Recently, a few prospective studies have implicated the diagnostic role of micro RNAs in congenital heart defects(CHD).DATA RESOURCES: This review retrieved the research articles in Pub Med focusing on the altered microR NAs in cardiac tissue or serum of patients with CHD versus healthy normal controls, as well as the studies exploring circulating microR NAs as potential biomarkers for(fetal) CHD.RESULTS: Most of the studies of interest were conducted in recent years, implicating that the topic in this review is a newly emerging field and is drawing much attention. Moreover, a number of differentially expressed microR NAs between CHD specimens and normal controls have been reported.CONCLUSION: Circulating micro RNAs may serve as potential biomarkers for diagnosis of CHD in the future, with more efforts paving the road to the aim.展开更多

The last decade has witnessed significant technical advances in the field of radiological imaging and also in interventional cardiology which has helped to offer more non-invasive solutions for the management of congenital heart defects. This has resulted from the use of advanced 3-dimensional fusion imaging instead of conventional 2-dimensional angiography, applying interactive real-time enhancement and using computed tomography and Magnetic Resonance Imaging for interventional procedures. Similarly the introduction of next generation devices, have not only improved the final outcome of the procedure but also has helped in reducing the challenges that were faced before and with the initial generation of devices. These advances have helped not only in reducing the radiation exposure, the use of contrast medium dose but also have resulted in improved early survival. The field of neonatal cardiology has advanced at an unprecedented pace. The transcatheter closure of patent ductus arteriosus has evolved over time and now it has been made possible at much lower body weight. Similarly, early use of stents for aortic coarctation has been found effective in some patients, especially when surgical intervention had been denied. The application of the hybrid approach for the management of complex congenital heart defects has also been effectively applied. More recently transcatheter placement of the pulmonary valve has been introduced for severely stenotic and/or regurgitant pulmonary valve in adolescents and adults. It is anticipated that in near future, this procedure would be available for relatively younger patients. In conclusion: last 2 decades have improvised pediatric interventional cardiology to incorporate less invasive solutions for CHD. The current advances in radio-diagnostic imaging, gadgetry and technical expertise have improved significantly and led to manage many of such defects by trans-catheter approach. This has led also, to replace the early surgical intervention with a more subtle hybrid approach, thus reducing not only the major surgical trauma but also been found to be cost-effective due to a shorter hospital stay. But a learning curve for performers is required for optimum results and also such procedures should be performed in a fully developed facility with an optimum surgical backup.展开更多

Method: Population based prospective observational study. Material: CHDs in infants born alive in a Norwegian county 1982-2011. Results: In 828/71 217 infants (12 per 1000) a CHD was diagnosed. The prevalence increased from 8 to 12 per 1000 after introduction of early echocardiography in newborns with suspected CHD from 1986 (p = 0.0001). Ventricular septal defect (VSD) was the dominating CHD (474;57%). In 222 (27%) the CHDs were missed and diagnosed after discharge from hospital after birth. Twelve critical CHDs (causing death or requiring invasive procedures before 28 days of life) were missed. Prenatal diagnosis of critical CHDs increased from 4/67 (6%) born 1997-2006 to 4/11 (36%) born 2007-2011 (p = 0.01). In 177 (21%) a syndrome or extracardial defect occurred. The occurrence of CHDs associated with chromosomal disorders (60/73 (82%) trisomies) more than doubled from the cohort born in the first 10-year period 1982-1991 (0.6 per 1000) to the last 2002-2011 (1.4 per 1000) (p < 0.0001) in parallel with increasing births in women ≥ 35 years old in the population. 237 (29%) underwent therapeutic procedures (203 (86%) surgery, of whom 16 after initial catheter intervention, and 34 (14%) catheter intervention alone). 39/237 (16%) died, 101 (43%) were repaired and 97 (41%) had some minor residual defect. The death rate declined significantly from 65/532 (12%) born 1982-2001 to 11/296 (4%) born 2002-2011 (p = 0.0001). 37/76 (49%) deaths occurred within 28 days after birth. Conclusions: The rate of detection of CHDs increased substantially after introduction of echocardiography in newborns with suspected CHD, especially VSDs. Some critical CHDs were overlooked. The prenatal detection rate of such defects increased. The prevalence of CHDs with associated chromosomal disorders increased in parallel with increasing maternal age in the population. Most deaths occurred during the neonatal period. Increasing survival increases the load on long-term follow-up programmes.展开更多

Methods One hundred and ninety-two CHD patients and their parents were included in this study as case group in Liaoning Province by birth defect registration cards, and 124 healthy subjects (age and gender matched) and their parents were simultaneously selected from the same geographic area as control. Their gene polymorphism of MTHFD G1958A locus was examined with PCR-RFLP, and serum folic acid and homocysteine (Hcy) levels were tested with radio-immunoassay and fluorescence polarization immunoassay (FPIA). Results There existed gene polymorphism at MTHFD G1958A locus in healthy subjects living in North China. The percentages of GG, GA, and AA genotype were 57.98%, 35.57%, and 6.45% respectively, and the A allele frequency was 24.23%, which was significantly different from Western population. No difference was observed when comparing genotype distribution and allele frequency between the case and control groups, so was the result from the comparison between genders. The A allele frequency of arterial septal defect patients’ mothers (10.87%) was significantly lower than that of controls (28.15%) (P=0.014), with OR=0.31 (95% CI: 0.09-0.84), and no difference in the other subgroups. The percentage of at least one parent carrying A allele in arterial septal defect subgroup (43.48%) was significantly lower than that in controls (69.64%) (P=0.017), with OR=0.34 (95% CI: 0.12-0.92). The analysis of genetic transmission indicated that there was no transmission disequillibrium in CHD nuclear families. Their serum folic acid level was significantly higher than that of controls (P=0.000), and Hcy level of the former was higher than that of the latter with no statistical significance (P>0.05). Serum Hcy and folic acid levels of mothers with gene mutation were lower than those of mothers with no mutation. Conclusion No significant difference of genotype distribution and allele frequency existed between CHD patients and healthy population. MTHFD G1958A mutation in parents (particularly in mother) can decrease the risk of arterial septal defect in offspring. The possible mechanism of protection might be mutation, which can increase MTHFD enzyme activity, folic acid metabolism and homocysteine remethylation, and decrease Hcy level.展开更多

We only use non-selective beta blockers in these infants, carvedilol in those with left ventricular dysfunction and propranolol in those with congenital heart disease without ventricular dysfunction. Despite a significant improvement of Ross’s heart failure score, we could not convince most colleagues within the last 25 years if the concept of neurohumoral activation in heart failure is not well-established pediatric cardiology. Recently, Honghai Liu et al. published that cardiomyocyte cytokinesis failure was increased in congenital heart disease. Inactivation of the beta adreno receptors genes and administration of the beta-blocker propranolol increased cardiomyocyte division in neonatal mice, which increased the number of cardiomyocytes (endowment) and conferred benefit after myocardial infarction in adults. We currently realize that propranolol in infants with congenital heart disease not only decrease highly elevated NT-Pro-BNP values but also decrease cardiac troponin T values that may indicate myocardial injury due to neurohumoral activation. We reproduce this observation, primarily seen in infants with congenital heart disease, in an infant with Duchenne muscular dystrophy. These observations were in good accordance with current data from H. Liu et al., who showed that treatment with non-selective beta blockers early after birth might rescue cytokinesis defects and prevent heart dysfunction in adulthood in a mouse model.展开更多

There are problems at both pediatric and adult ages with high morbidity and mortality on account of inadequate surgical care. Objective: To determine the status of congenital defects and assess the impact of foreign cardiac missionary missions vis-à-vis the effects on the magnitude as well as on the educational program for the local cardiac team. Materials and Method: In the last 5.5 years, Foreign Cardiac Surgery missions were reinstituted at National Cardiothoracic Center of Excellence, Enugu, Nigeria. The participants performed cardiac interventions on a variety of patients with CHD. We performed a retrospective review of this endeavor. Patients’ demographics, number of patients, age ranges, types of CHD and clinical evaluation methodology were obtained from our hospital’s record department. We also assessed types of cardiac interventions, outcome and challenges and the impacts of the foreign cardiac surgery missions. Results:?During the study period, a total of 72 children with CHD were evaluated. They were 39 males and 33 females. The age ranged between 0 - 10 years in children and 41 - 50 years in the adult. We studied both simple and complex anomalies. A VSD was the commonest (n = 22, 27.16%). Conclusion: Foreign congenital cardiac surgery missions were not able to provide adequate services for the care of CHD that require cardiac surgery both in terms of reduction in magnitude as well as adequate educational program for the local cardiac team. Thus infants, in particular, suffer an early death. The need for governmental support to develop a comprehensive program to care for these patients is essential in Nigeria and other developing countries.展开更多

The aim of this study was to investigate the long-term mortality of children with congenital heart disease admitted to the Departmental University Hospital of Borgou/Alibori (CHUD-B/A) from 2011 to 2022. Methods: This descriptive longitudinal study with analytical aims covered 11 years (April 1, 2011 to December 31, 2022). It consisted of a review of the records of children under 15 years of age with echocardiographically confirmed congenital heart disease. This was followed by an interview with the parents to assess the children’s current condition. Data were entered using Kobocollect software and analyzed using R Studio 4.2.2. software. Results: A total of 143 complete files were retained. The median age at diagnosis was 14 months (IIQ: Q1 = 4;Q3 = 60) with a range of 2 days and 175 months, and the sex-ratio (M/F) was 0.96. Left-to-right shunts were the most frequent cardiopathy group (62.9%). Only 35 children (24.5%) benefited from restorative treatment. The mortality rate was 31.5%. Median survival under the maximum bias assumption was 114 months and 216 months under the assumption of minimum bias. Survival was significantly better in children with right-to-left shunts (p = 0.0049) under the assumption of minimum bias. The death risk factors were: age at diagnosis less than 12 months (aHR = 7.58;95% CI = 3.36 - 17.24;p Conclusion: The long-term mortality of congenital heart disease is high and favoured by the absence of restorative treatment. Local correction of congenital heart disease and medical follow-up will help to reduce this mortality.展开更多

文摘Background:The management of suspected critical congenital heart defects(CCHD)relies on timely echocardiographic diagnosis.The availability of experienced echocardiographers is limited or even non-existent in many hospitals with obstetric units.This study evaluates remote-mentored echocardiography performed by physicians without experience in imaging of congenital heart defects(CHD).Methods:The setup included a pediatric cardiologist in a separate room,guiding a physician without experience in echocardiographic imaging of CHD in the examination of a symptomatic newborn.This remote-mentoring pair was blinded to the diagnosis of the newborn and presented with a simplified patient history.The echocardiographic images were streamed to the laptop of the mentor,along with a webcam feed showing the probe position.The task was to identify CCHD in need of immediate transfer to a pediatric cardiac surgical center.The result was compared to the previously completed echocardiographic report and the clinical decision of the patient-responsible pediatric cardiologist.Results:During 17 months,15 newborns were recruited.All six newborns with CCHD were correctly labeled by the remotementoring pair.One newborn with Tetralogy of Fallot was erroneously labeled as needing immediate transfer.Eight newborns without CCHD were correctly labeled.Conclusions:Remote-mentored echocardiography performed by examiners without experience in imaging CHD identified all newborns with CCHD in need of immediate transfer for specialist care.The setup shows promising results for improving the management of CCHD in hospitals without continuous pediatric cardiology service.

文摘Background:Research on fetal congenital heart defect(CHD)mostly focuses on etiology and mechanisms.However,studies on maternal complications or pathophysiology are limited.Our objective was to determine whether vascular dysfunction exists in pregnant women carrying a fetus with congenital heart defects.Methods:We conducted a case-control study.27 cases of pregnant women carrying a fetus with major CHD admitted to our hospital for delivery between April 2021 and August 2022 were selected.Every case was matched with about 2 pregnant complication-free controls without fetal abnormalities.The proangiogenic and anti-angiogenic factors and pregnancy outcomes were compared.Results:The proangiogenic factors include vascular endothelial growth factor(VEGF)and placental growth factor(PlGF).The anti-angiogenic factors involve soluble fms-like tyrosine kinase 1(sFlt-1)and soluble endoglin(sEng).No differences were found in maternal plasma concentrations of PlGF,VEGF,and sFlt-1 between case-control groups when analyzed at 36 weeks≤gestational age(GA)<39 weeks and 39 weeks≤GA≤41 weeks.The concentrations of sEng in maternal plasma in the fetal CHD group were significantly higher than those in the control group:0.60(0.77)vs.0.32(0.26)ng/ml at 36 weeks≤GA<39 weeks,p=0.001 and 0.75(0.55)vs.0.28(0.27)ng/ml at 39 weeks≤GA≤41 weeks,p<0.001.Conclusion:Vascular dysfunction exists in pregnant women with fetal congenital heart defects,manifesting significantly elevated sEng concentration at delivery.
文摘BACKGROUND: Micro RNAs are small non-coding RNAs of approximately 22 nucleotides in length, and play important regulatory roles in normal heart development and the pathogenesis of heart diseases. Recently, a few prospective studies have implicated the diagnostic role of micro RNAs in congenital heart defects(CHD).DATA RESOURCES: This review retrieved the research articles in Pub Med focusing on the altered microR NAs in cardiac tissue or serum of patients with CHD versus healthy normal controls, as well as the studies exploring circulating microR NAs as potential biomarkers for(fetal) CHD.RESULTS: Most of the studies of interest were conducted in recent years, implicating that the topic in this review is a newly emerging field and is drawing much attention. Moreover, a number of differentially expressed microR NAs between CHD specimens and normal controls have been reported.CONCLUSION: Circulating micro RNAs may serve as potential biomarkers for diagnosis of CHD in the future, with more efforts paving the road to the aim.

文摘Objective This study aimed to assess the associations between maternal drug use,cytochrome P450(CYP450)genetic polymorphisms,and their interactions with the risk of congenital heart defects(CHDs)in offspring.Methods A case-control study involving 569 mothers of CHD cases and 652 controls was conducted from November 2017 to January 2020.Results After adjusting for potential confounding factors,the results show that mothers who used ovulatory drugs(adjusted odds ratio[a OR]=2.12;95% confidence interval[CI]:1.08-4.16),antidepressants(a OR=2.56;95%CI:1.36-4.82),antiabortifacients(a OR=1.55;95%CI:1.00-2.40),or traditional Chinese drugs(a OR=1.97;95%CI:1.26-3.09)during pregnancy were at a significantly higher risk of CHDs in offspring.Maternal CYP450 genetic polymorphisms at rs1065852(A/T vs.A/A:OR=1.53,95%CI:1.10-2.14;T/T vs.A/A:OR=1.57,95%CI:1.07-2.31)and rs16947(G/G vs.C/C:OR=3.41,95%CI:1.82-6.39)were also significantly associated with the risk of CHDs in offspring.Additionally,significant interactions were observed between the CYP450 genetic variants and drug use on the development of CHDs.Conclusions In those of Chinese descent,ovulatory drugs,antidepressants,antiabortifacients,and traditional Chinese medicines may be associated with the risk of CHDs in offspring.Maternal CYP450 genes may regulate the effects of maternal drug exposure on fetal heart development.

文摘Early intervention to prevent premature mortality is vital for adults with congenital heart defects(CHD).Anatomic complexity and comorbid conditions are thought to contribute to CHD mortality.Since hypertension(HTN)and heart failure(HF)are the comorbid conditions among the most prevalent causes of death in the United States,and commonly accompany CHD,it is crucial to evaluate whether they are reliable predictors of mortality for adults with CHD(ACHD)independent of anatomic CHD complexity.A retrospective cross-sectional analysis of ACHD,aged 18–64,with concomitant HTN and/or HF and at least one health care encounter during 2008–2010 were assessed.Of 5,397 ACHD patients(18.3%HTN without HF,4.4%HF without HTN,8.3%with both),3.0%died(n=163)during the study period.Overall,the sample was 45.1%white,61.4%female,and 29.0%had a complex CHD.Among those who died,23.3%had HTN without HF,17.2%had HF without HTN,and 42.3%had both.Crude analyses revealed that older age,male gender,black race,and having public health insurance were associated with increased mortality during the three-year study period compared to ACHD patients who were younger,female gender,white race,and covered by private health insurance.ACHD patients diagnosed with non-complex CHD lesions(i.e.,shunts,valves,or shunts+valves)were at greater risk of dying compared to those with severe complex CHDs.When CHD type was assessed separately,those with valve lesions were more likely to die compared to those with complex CHD lesions.After adjustment for age,gender,race,insurance and CHD complexity,ACHD patients with HF,with or without HTN,were equally likely to die during the study period.However,ACHD patients with HF,without or without HTN,who had valve defects were more likely to die during the three-year study period compared to patients with complex CHDs.
文摘This review aims to sum up the improvements witnessed in the field of interventional cardiology during recent times. The last decade has witnessed significant technical advances in the field of radiological imaging and also in interventional cardiology which has helped to offer more non-invasive solutions for the management of congenital heart defects. This has resulted from the use of advanced 3-dimensional fusion imaging instead of conventional 2-dimensional angiography, applying interactive real-time enhancement and using computed tomography and Magnetic Resonance Imaging for interventional procedures. Similarly the introduction of next generation devices, have not only improved the final outcome of the procedure but also has helped in reducing the challenges that were faced before and with the initial generation of devices. These advances have helped not only in reducing the radiation exposure, the use of contrast medium dose but also have resulted in improved early survival. The field of neonatal cardiology has advanced at an unprecedented pace. The transcatheter closure of patent ductus arteriosus has evolved over time and now it has been made possible at much lower body weight. Similarly, early use of stents for aortic coarctation has been found effective in some patients, especially when surgical intervention had been denied. The application of the hybrid approach for the management of complex congenital heart defects has also been effectively applied. More recently transcatheter placement of the pulmonary valve has been introduced for severely stenotic and/or regurgitant pulmonary valve in adolescents and adults. It is anticipated that in near future, this procedure would be available for relatively younger patients. In conclusion: last 2 decades have improvised pediatric interventional cardiology to incorporate less invasive solutions for CHD. The current advances in radio-diagnostic imaging, gadgetry and technical expertise have improved significantly and led to manage many of such defects by trans-catheter approach. This has led also, to replace the early surgical intervention with a more subtle hybrid approach, thus reducing not only the major surgical trauma but also been found to be cost-effective due to a shorter hospital stay. But a learning curve for performers is required for optimum results and also such procedures should be performed in a fully developed facility with an optimum surgical backup.
文摘The objective of the work is to study the topographic and anatomical characteristics of the atrioventricular node’s artery in complex congenital heart defects.The material for the work was the following:44 specimens including hearts of fetuses and children of the first three years having congenital defects and 50 specimens of the hearts of a similar age with normal development as the control.A complex of generally accepted morphological methods was used to identify the conductive system of the heart,its blood supply.According to the data obtained given congenital heart defects,the artery of the atrioventricular node arises from an artery,that determines the type of blood supply to the heart.With the full form of the common atrioventricular canal,the presence of the“U”-shaped bend of the coronary artery at the point of departure of the atrioventricular artery from it is inconstant,which is apparently due to the localization of the atrioventricular node in the embryonic position.The intensity of the lateral branches from the artery of the atrioventricular node to the heart partitions is determined by the hemodynamic features with congenital heart defects.

文摘Aim: To assess basic trends in epidemiology of congenital heart defects (CHDs). Method: Population based prospective observational study. Material: CHDs in infants born alive in a Norwegian county 1982-2011. Results: In 828/71 217 infants (12 per 1000) a CHD was diagnosed. The prevalence increased from 8 to 12 per 1000 after introduction of early echocardiography in newborns with suspected CHD from 1986 (p = 0.0001). Ventricular septal defect (VSD) was the dominating CHD (474;57%). In 222 (27%) the CHDs were missed and diagnosed after discharge from hospital after birth. Twelve critical CHDs (causing death or requiring invasive procedures before 28 days of life) were missed. Prenatal diagnosis of critical CHDs increased from 4/67 (6%) born 1997-2006 to 4/11 (36%) born 2007-2011 (p = 0.01). In 177 (21%) a syndrome or extracardial defect occurred. The occurrence of CHDs associated with chromosomal disorders (60/73 (82%) trisomies) more than doubled from the cohort born in the first 10-year period 1982-1991 (0.6 per 1000) to the last 2002-2011 (1.4 per 1000) (p < 0.0001) in parallel with increasing births in women ≥ 35 years old in the population. 237 (29%) underwent therapeutic procedures (203 (86%) surgery, of whom 16 after initial catheter intervention, and 34 (14%) catheter intervention alone). 39/237 (16%) died, 101 (43%) were repaired and 97 (41%) had some minor residual defect. The death rate declined significantly from 65/532 (12%) born 1982-2001 to 11/296 (4%) born 2002-2011 (p = 0.0001). 37/76 (49%) deaths occurred within 28 days after birth. Conclusions: The rate of detection of CHDs increased substantially after introduction of echocardiography in newborns with suspected CHD, especially VSDs. Some critical CHDs were overlooked. The prenatal detection rate of such defects increased. The prevalence of CHDs with associated chromosomal disorders increased in parallel with increasing maternal age in the population. Most deaths occurred during the neonatal period. Increasing survival increases the load on long-term follow-up programmes.

文摘To investigate the relationship between G1958A gene polymorphism of methylenetetrahydrofolate dehydrogenase (MTHFD) and occurrence of congenital heart disease (CHD) in North China. Methods One hundred and ninety-two CHD patients and their parents were included in this study as case group in Liaoning Province by birth defect registration cards, and 124 healthy subjects (age and gender matched) and their parents were simultaneously selected from the same geographic area as control. Their gene polymorphism of MTHFD G1958A locus was examined with PCR-RFLP, and serum folic acid and homocysteine (Hcy) levels were tested with radio-immunoassay and fluorescence polarization immunoassay (FPIA). Results There existed gene polymorphism at MTHFD G1958A locus in healthy subjects living in North China. The percentages of GG, GA, and AA genotype were 57.98%, 35.57%, and 6.45% respectively, and the A allele frequency was 24.23%, which was significantly different from Western population. No difference was observed when comparing genotype distribution and allele frequency between the case and control groups, so was the result from the comparison between genders. The A allele frequency of arterial septal defect patients’ mothers (10.87%) was significantly lower than that of controls (28.15%) (P=0.014), with OR=0.31 (95% CI: 0.09-0.84), and no difference in the other subgroups. The percentage of at least one parent carrying A allele in arterial septal defect subgroup (43.48%) was significantly lower than that in controls (69.64%) (P=0.017), with OR=0.34 (95% CI: 0.12-0.92). The analysis of genetic transmission indicated that there was no transmission disequillibrium in CHD nuclear families. Their serum folic acid level was significantly higher than that of controls (P=0.000), and Hcy level of the former was higher than that of the latter with no statistical significance (P>0.05). Serum Hcy and folic acid levels of mothers with gene mutation were lower than those of mothers with no mutation. Conclusion No significant difference of genotype distribution and allele frequency existed between CHD patients and healthy population. MTHFD G1958A mutation in parents (particularly in mother) can decrease the risk of arterial septal defect in offspring. The possible mechanism of protection might be mutation, which can increase MTHFD enzyme activity, folic acid metabolism and homocysteine remethylation, and decrease Hcy level.
文摘Our first intention to treat infants’ heart failure with beta blockers was to improve the clinical condition as shown in our prospective randomized trial. We only use non-selective beta blockers in these infants, carvedilol in those with left ventricular dysfunction and propranolol in those with congenital heart disease without ventricular dysfunction. Despite a significant improvement of Ross’s heart failure score, we could not convince most colleagues within the last 25 years if the concept of neurohumoral activation in heart failure is not well-established pediatric cardiology. Recently, Honghai Liu et al. published that cardiomyocyte cytokinesis failure was increased in congenital heart disease. Inactivation of the beta adreno receptors genes and administration of the beta-blocker propranolol increased cardiomyocyte division in neonatal mice, which increased the number of cardiomyocytes (endowment) and conferred benefit after myocardial infarction in adults. We currently realize that propranolol in infants with congenital heart disease not only decrease highly elevated NT-Pro-BNP values but also decrease cardiac troponin T values that may indicate myocardial injury due to neurohumoral activation. We reproduce this observation, primarily seen in infants with congenital heart disease, in an infant with Duchenne muscular dystrophy. These observations were in good accordance with current data from H. Liu et al., who showed that treatment with non-selective beta blockers early after birth might rescue cytokinesis defects and prevent heart dysfunction in adulthood in a mouse model.

文摘Objective Congenital heart defect (CHD) is one of the most common birth anomalies with high morbidity and mortality. Previous studies of CHD mostly focus on the postnatal prevalence, mortality and successful rate of operation, etc. This study aimed to explore the detection rate of prenatal CHD and CHD factors that attribute to termination of pregnancy (TOP).
文摘Background: Unlike in developed countries, the delivery of cardiovascular services to children born with congenital heart defects in Nigeria is inadequate. There are problems at both pediatric and adult ages with high morbidity and mortality on account of inadequate surgical care. Objective: To determine the status of congenital defects and assess the impact of foreign cardiac missionary missions vis-à-vis the effects on the magnitude as well as on the educational program for the local cardiac team. Materials and Method: In the last 5.5 years, Foreign Cardiac Surgery missions were reinstituted at National Cardiothoracic Center of Excellence, Enugu, Nigeria. The participants performed cardiac interventions on a variety of patients with CHD. We performed a retrospective review of this endeavor. Patients’ demographics, number of patients, age ranges, types of CHD and clinical evaluation methodology were obtained from our hospital’s record department. We also assessed types of cardiac interventions, outcome and challenges and the impacts of the foreign cardiac surgery missions. Results:?During the study period, a total of 72 children with CHD were evaluated. They were 39 males and 33 females. The age ranged between 0 - 10 years in children and 41 - 50 years in the adult. We studied both simple and complex anomalies. A VSD was the commonest (n = 22, 27.16%). Conclusion: Foreign congenital cardiac surgery missions were not able to provide adequate services for the care of CHD that require cardiac surgery both in terms of reduction in magnitude as well as adequate educational program for the local cardiac team. Thus infants, in particular, suffer an early death. The need for governmental support to develop a comprehensive program to care for these patients is essential in Nigeria and other developing countries.
文摘In this editorial,we comment on the article by Kong et al published in the recent issue of the World Journal of Cardiology.In this interesting case,the authors present the challenges faced in managing a 13-year-old patient with Down syndrome(DS)and congenital heart disease(CHD)associated with pulmonary arterial hypertension.In this distinct population,the Authors underscore the need for early diagnosis and management as well as the need of a multidisciplinary approach for decision making.It seems that the occurrence of CHD in patients with DS adds layers of complexity to their clinical management.This editorial aims to provide a comprehensive overview of the intricate interplay between DS and congenital heart disorders,offering insights into the nuanced diagnostic and therapeutic considerations for physicians.
文摘1 Background Congenital heart disease(CHD)is the most common major congenital anomaly,affecting approximately one in every 100 live births[1].Among congenital anomalies,66%of preventable deaths are due to CHD,and 58%of the avertable morbidity and mortality due to congenital anomalies would result from scaling congenital heart surgery services[2].Every year,nearly 300,000 children and adults die from CHD,the majority of whom live in low-and middle-income countries(LMICs)[3].Approximately 49%of all individuals with CHD will require surgical or interventional care at some point in their lifetime[4];as a result of advances in access to and the delivery of such services,over 95%of children born with CHD in high-income countries now live into adulthood[3].Here,adults have surpassed children in the number of CHD cases at a ratio of 2:1[5].

文摘Congenital heart disease(CHD),the most prevalent congenital ailment,has seen advancements in the“dual indi-cator”screening program.This facilitates the early-stage diagnosis and treatment of children with CHD,subse-quently enhancing their survival rates.While cardiac auscultation offers an objective reflection of cardiac abnormalities and function,its evaluation is significantly influenced by personal experience and external factors,rendering it susceptible to misdiagnosis and omission.In recent years,continuous progress in artificial intelli-gence(AI)has enabled the digital acquisition,storage,and analysis of heart sound signals,paving the way for intelligent CHD auscultation-assisted diagnostic technology.Although there has been a surge in studies based on machine learning(ML)within CHD auscultation and diagnostic technology,most remain in the algorithmic research phase,relying on the implementation of specific datasets that still await verification in the clinical envir-onment.This paper provides an overview of the current stage of AI-assisted cardiac sounds(CS)auscultation technology,outlining the applications and limitations of AI auscultation technology in the CHD domain.The aim is to foster further development and refinement of AI auscultation technology for enhanced applications in CHD.
文摘Background:Patients with congenital heart disease(CHD)will transition to lifelong adult congenital cardiac care.However,their structural heart disease is challenging to convey via two-dimensional drawings.This study utilized a tele-educational environment,with personalized three-dimensional(3D)modeling and health Details(3D+Details=“4D”),to improve actual and perceived knowledge,both important components of transition readiness in CHD patients.Methods:Participants aged≥13 years with a history of CHD and cardiac magnetic resonance imaging(MRI)studies were eligible.Cardiac MRI datasets were then used to segment and create 3D heart models(using Mimics,Materialize Inc.).Participantsfirst completed the MyHeart Questionnaire,a validated survey of actual knowledge.A tele-educational session was then scheduled,during which participants were shown a 3D model of a normal heart,followed by their personal 3D heart model and specific health details.Participants then repeated the actual knowledge survey,in addition to questionnaires assessing perceived knowledge pre-and post-session,as well as a satisfaction survey.Results:Twenty-two patients were included.Actual knowledge increased from 75%±15%to 89%±20%(p=0.00043)and perceived knowledge increased infive of seven questions.Actual knowledge correlated with perceived knowledge(r=0.608,p<0.0001).Ninety-one percent of participants ranked the 3D model as“very satisfactory”and ninety-five percent ranked the educational session as“very help-ful”or“extremely helpful.”Conclusions:The use of“4D”tele-education increased both actual and perceived knowledge and may help improve transition readiness in CHD patients.
文摘Background: Congenital heart disease is a public health issue due to its incidence and mortality rate. The aim of this study was to investigate the long-term mortality of children with congenital heart disease admitted to the Departmental University Hospital of Borgou/Alibori (CHUD-B/A) from 2011 to 2022. Methods: This descriptive longitudinal study with analytical aims covered 11 years (April 1, 2011 to December 31, 2022). It consisted of a review of the records of children under 15 years of age with echocardiographically confirmed congenital heart disease. This was followed by an interview with the parents to assess the children’s current condition. Data were entered using Kobocollect software and analyzed using R Studio 4.2.2. software. Results: A total of 143 complete files were retained. The median age at diagnosis was 14 months (IIQ: Q1 = 4;Q3 = 60) with a range of 2 days and 175 months, and the sex-ratio (M/F) was 0.96. Left-to-right shunts were the most frequent cardiopathy group (62.9%). Only 35 children (24.5%) benefited from restorative treatment. The mortality rate was 31.5%. Median survival under the maximum bias assumption was 114 months and 216 months under the assumption of minimum bias. Survival was significantly better in children with right-to-left shunts (p = 0.0049) under the assumption of minimum bias. The death risk factors were: age at diagnosis less than 12 months (aHR = 7.58;95% CI = 3.36 - 17.24;p Conclusion: The long-term mortality of congenital heart disease is high and favoured by the absence of restorative treatment. Local correction of congenital heart disease and medical follow-up will help to reduce this mortality.
