The CHD patients were divided into 3 groups according to pulmonary artery systolic pressure (PASP): Non-PH group: PASP≤30 mmHg ( n =11); mild-PH group: PASP 31-49 mmHg ( n =10); moderate or severe-PH group: PASP≥50 mmHg ( n =12). The control group consisted of 15 health children. Plasma ADM, ET-1 and NO levels were determined by radioimmunoassay and colorimetry methods. The correlation between ADM and ET-1, NO, PASP was analyzed. The changes in plasma ADM, ET-1 and plasma NO on the 7th day after operation among the groups were compared. The results showed that plasma ADM levels in non-PH group were significantly higher than that in control group ( P <0.05), but there was no significant difference in ET-1 and NO levels between the two groups ( P >0.05). ADM and ET-1 levels in mild-PH group were significantly elevated as compared with those in non-PH group (both P <0.05), but NO levels were decreased ( P <0.05). ADM and ET-1 levels in moderate or severe-PH groups were increased as compared with those in mild-PH group (both P <0.01), but NO level significantly declined ( P <0.05). On the 7th day after operation, plasma ADM and ET-1 levels in PH group were significantly decreased ( P <0.05, P <0.01) as compared with those before operation, but there was no significant difference in NO levels ( P >0.05). But NO levels in non-PH group were significantly increased ( P <0.05). Plasma ADM levels in CHD were positively correlated with PASP and ET-1 ( r =0.77, P <0.01; r =0.82, P <0.01), negatively correlated with NO ( r =-0.56, P <0.05). It was concluded that during the progression of PH in the cases of CHD, plasma ADM, ET-1 and NO might play an important role in the development of PH. The increased ADM may represent a compensatory mechanism. It can interact with NO and ET-1 to regulate pulmonary circulation in the pathophysiology of PH with CHD. ADM may be involved in the defence mechanism against further increase of pulmonary arterial pressure. ADM could be used as a reliable indicator of the severity of CHD associated PH.展开更多

Information was collected on collateral origin, arch sidedness, presence of central pulmonary arteries, and presence of an aberrant subclavian vessel. While patients with 22q11 deletion were more likely to have collateral origin from brachiocephalic vessels, patients without 22q11 deletion were more likely to have collateral origin from the descending aorta. There was no significant difference in arch sidedness or the presence of central pulmonary arteries. Patients with 22q11 deletion were more likely to have an aberrant subclavian artery (15/46 vs 5/54, p < 0.05), whether a left or right arch was present. Nine of the fifteen 22q11 deletion patients had a collateral originating from an aberrant subclavian artery. In time, genomic and embryologic research may help determine the exact mechanisms by which 22q11 deletion contributes to the development of congenital heart disease such as pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals.展开更多

Methods Twenty patients with simple ventricular septal defect (VSD) were chosen as controls, and 30 patients with PH were studied. Plasma levels of ET-1 and NO were measured by radioimmunoassay or colorimetric method. Before cardiopulmonary bypass was established, the specimens from right lung were fixed with formaldehyde solution, embedded with paraffin and stained by SP immunohistochemistry. Intercellular adhesion molecule-1 (ICAM-1) expression was measured through the determination of the light density with computer imaging technology. Results Compared with that of the patients with simple VSD, the light density of ICAM-1 and plasma level of ET-1 increased in patients with PH; but plasma level of NO decreased (P<0.05). Positive correlation was observed between ICAM-1 and ET-1/NO (P<0.05). Conclusion Endothelia cells activation and imbalance of ET-1/NO might play an important role in the development of PH.展开更多

Multidisciplinary approach, good family support, well established doctorepatient relationship and well organised patient-support groups are the essential elements for success. With the advancement of implantable hearing devices,more options will be available for the microtia patients. Otologists play a leading role in the whole management process. They not only provide proper guidance to the patients in choosing the correct path of the treatment, but also play a key role in organising and maintaining a costeffective multidisciplinary rehabilitation team for the microtia patients.展开更多

Occurrence of aural ...Aural atresia is a rare congenital malformation of the external and middle ear. There are several syndromic associations of this anomaly with those involving the first and second branchial arches. Occurrence of aural atresia with sclerosing skeletal dysplasia is unknown and has never been reported. The coexistence of a sclerosing dysplasia can make the surgical treatment in aural atresia difficult and risky; and the auditory improvement may not be as expected. Moreover, internal auditory canal narrowing and hence sensorineural hearing loss in sclerosing dysplasia might add to the already existing conductive hearing loss in such patients. In this case report we have described an unknown association of bilateral microtia with sclerosing skeletal dysplasia(autosomal dominant osteopetrosis) and clinical implications of these two conditions occurring together leading to a change in the management plan.展开更多

文摘Background:Pulmonary atresia(PA)is a group of heterogeneous complex congenital heart disease.Only one study modality might not get a correct diagnosis.This study aims to investigate the diagnostic power of dualsource computed tomography(DSCT)for all intracardiac and extracardiac deformities in patients with PA compared with transthoracic echocardiography(TTE).Materials and Methods:This retrospective study enrolled 79 patients and divided them into three groups according to their main diagnosis.All associated malformations and clinical information,including treatments,were recorded and compared among the three groups.The diagnostic power of DSCT and TTE on all associated malformations were compared.The surgical index(McGoon ratio,pulmonary arterials index(PAI),and total neopulmonary arterial index)and radiation dose were calculated on the basis of DSCT.Results:Of the patients,32,30,and 17 were divided into the groups of PA with ventricular septal defect(VSD),PA with VSD and major aortopulmonary collateral arteries,and PA with other major malformations,respectively.Consequently,182,162,and 13 intracardiac,extracardiac,and other major malformations were diagnosed,respectively.Moreover,DSCT showed a better diagnostic performance in extracardiac deformities(154 vs.117,p<0.001),whereas TTE could diagnose intracardiac deformities better(159 vs.139,p=0.001).The McGoon ratio,PAI,and treatment methods were significantly different among the three groups(p=0.014,p=0.008,and p=0.018,respectively).Conclusion:More than one imaging modality should be used to make a correct diagnosis when clinically suspecting PA.DSCT is superior to TTE in diagnosing extracardiac deformities and could be used to roughly calculate surgical indices to optimize treatment strategy.
文摘Objectives:To access the effectiveness of our modified right-ventricular overhauling procedure on tricuspid valve(TV)growth in patients with pulmonary atresia with intact ventricular septum(PAIVS).Methods:We retrospectively reviewed 21 patients with PAIVS who underwent modified right ventricular overhauling(mRVoh)between 2008 and 2019 at two institutions.Our mRVoh consisted of wide resection of hypertrophied infundibular and trabecular muscle,peeling off fibrotic endocardial tissue in the right ventricle(RV)cavity,surgical pulmonary valvotomy,and Blalock-Taussig shunt or banding of ductus arteriosus under cardiopulmonary bypass.The TV annulus sizes were measured and analyzed using echocardiography before and after mRVoh.Results:No mortalities were observed during a median follow-up of 3 years(interquartile range:1.3–4.7 years)of follow-up were noted.mRVoh was performed at a median age of 163.5 days(range:21–560 days),including seven neonates and two infants(<60 days).During follow-up,the median TV annular z-score increased significantly from−2.24 to−1.15 before and after mRVoh(p=0.004).In ten patients with a prior history of percutaneous interventions for RV outflow tract(RVOT)widening at least 6 months before mRVoh,the TV annular z-score significantly changed during the period after mRVoh(−2.03 to−1.61,p=0.028)compared with the period before mRVoh(−2.51→–2.03,p=0.575)after percutaneous intervention only.Conclusions:mRVoh in PAIVS patients was positively associated with TV annular growth,and it was more effective than percutaneous RVOT widening interventions without mRVoh.

文摘The changes of adrenomedullin (ADM), endothelin-1 (ET-1) and nitric oxide (NO) levels before and after operation in congenital heart disease (CHD) associated with pulmonary hypertension (PH) were observed in order to investigate their role in CHD with PH and their clinical significance. The CHD patients were divided into 3 groups according to pulmonary artery systolic pressure (PASP): Non-PH group: PASP≤30 mmHg ( n =11); mild-PH group: PASP 31-49 mmHg ( n =10); moderate or severe-PH group: PASP≥50 mmHg ( n =12). The control group consisted of 15 health children. Plasma ADM, ET-1 and NO levels were determined by radioimmunoassay and colorimetry methods. The correlation between ADM and ET-1, NO, PASP was analyzed. The changes in plasma ADM, ET-1 and plasma NO on the 7th day after operation among the groups were compared. The results showed that plasma ADM levels in non-PH group were significantly higher than that in control group ( P <0.05), but there was no significant difference in ET-1 and NO levels between the two groups ( P >0.05). ADM and ET-1 levels in mild-PH group were significantly elevated as compared with those in non-PH group (both P <0.05), but NO levels were decreased ( P <0.05). ADM and ET-1 levels in moderate or severe-PH groups were increased as compared with those in mild-PH group (both P <0.01), but NO level significantly declined ( P <0.05). On the 7th day after operation, plasma ADM and ET-1 levels in PH group were significantly decreased ( P <0.05, P <0.01) as compared with those before operation, but there was no significant difference in NO levels ( P >0.05). But NO levels in non-PH group were significantly increased ( P <0.05). Plasma ADM levels in CHD were positively correlated with PASP and ET-1 ( r =0.77, P <0.01; r =0.82, P <0.01), negatively correlated with NO ( r =-0.56, P <0.05). It was concluded that during the progression of PH in the cases of CHD, plasma ADM, ET-1 and NO might play an important role in the development of PH. The increased ADM may represent a compensatory mechanism. It can interact with NO and ET-1 to regulate pulmonary circulation in the pathophysiology of PH with CHD. ADM may be involved in the defence mechanism against further increase of pulmonary arterial pressure. ADM could be used as a reliable indicator of the severity of CHD associated PH.

文摘Background:Never had literatures characterized the relationship between the property of major aortopulmonary collateral arteries(MAPCAs)and outcomes of selective unifocalization of pulmonary atresia with ventricular septal defects and MAPCAs.Methods:This is a case-series study.Thirteen patients were included.Angiographybased assessment was conducted to determine whether collateral arteries should be unifocalized or treated with intraoperative ligature.Specimens were collected and stained by HE and ET+VG.Results:Twelve patients underwent one-stage unifocalization at a median age of 37 months(range:6–228 months)and a median weight of 14.0 kg(range:5.0–49.0 kg),which produced a favorable right ventricle to aortic systolic pressure ratio of no more than 0.5 except in one patient who died.Patients were divided into three groups:Group 1(n=6),had no native pulmonary arteries,and collateral arteries supplied all pulmonary blood;Group 2(n=6)presented dysplastic native pulmonary arteries on one or both sides,and in some lung lobes or segments,blood was supplied only by collateral arteries;Group 3(n=1)had well-developed left and right pulmonary arteries,and collateral arteries,and pulmonary arteries provided blood flow to the same segments.Pathological reports demonstrated two types of collateral arteries:Elastic arteries presented an arborization distribution similar to native pulmonary artery walls,while muscular arteries showed high resistance and distortion.We selectively unifocalized single-supply collateral arteries with morphologic features based on the arborization distribution.Conclusions:We found that there were two kinds of MAPCAs with different histology,and we performed selective UF for MAPCAs that might belong to the elastic artery.Selective unifocalization achieved a low right ventricle to aortic systolic pressure ratio and favorable surgical effects.

文摘Objective:Pulmonary atresia(PA)is a rare type of complex cyanotic congenital heart defect characterized primarily by an undeveloped pulmonary valve or pulmonary artery.Therefore,defining a disease-causing gene mutation in a pulmonary atresia family is a possible method of genetic counseling,future prenatal diagnosis,and therapeutic approaches for pulmonary atresia.Methods:Blood samples were collected from six PA family members,and genomic DNA was extracted using the QIAamp DNA Blood Mini Kit.Gene detection was performed using a second-generation sequencing gene panel.Results:Genetic testing results indicated that a heterozygous mutation originating from maternal inheritance was detected in the BMPR2 gene of the proband’s genomic DNA.The pathogenic gene was c.2804C>T(p.A935V).The mutation was also detected in the genomic DNA of the proband’s elder brother(III-1),but not in other family members.Conclusion:To the best of our knowledge,this is the first study to report the BMPR2 variant responsible for pulmonary atresia.The frequency of the c.2804C>T(p.A935V)mutation detected in this family is extremely low in the normal population(1/246048).The mutation was highly conserved among different species.Sorting intolerant from tolerant(SIFT)predicts it to be a harmful mutation.
文摘BACKGROUND Ductal spasm is a rare but life-threatening complication of cardiac catheterization in neonates with pulmonary atresia and an intact ventricular septum.In patients with ductal-dependent pulmonary blood flow,ductal spasm may lead to refractory hypoxemia and severe hemodynamic instability,which need to be treated in perfect order.CASE SUMMARY We present a male infant with a gestational age of 39 wk,and his fetal echocardiography showed pulmonary atresia.At 28 d of age,transcatheter pulmonary valvuloplasty with balloon dilatation was performed.Two hours after the operation,the patient's pulse oxygen saturation continued to decrease.The patient was then transferred to receive cardiac catheterization.During catheterization,the invasive blood pressure and pulse oxygen saturation suddenly decreased,and repeated aortography revealed partial occlusion of the ductus arteriosus.It no longer changed when pulse oxygen saturation rose to 51%after approximately 20 min of maintenance therapy.Therefore,a ductal stent was used for implantation.Hemodynamics and hypoxemia were improved.CONCLUSION We should know that ductal spasm may occur during pulmonary atresia and intact ventricular septum cardiac catheterization.Understand the pathophysiology of ductal-dependent pulmonary blood flow and make comprehensive perioperative preparations essential to deal with hemodynamic disorders caused by ductal spasm.
文摘Introduction:While previous studies only focused on the arrhythmic risk associated with specific correction strategies,this study evaluates this risk in a large cohort of paediatric patients with all phenotypes of PA-IVS after surgical repair.Methods:In this single centre observational cohort study,we retrospectively evaluated 165 patients with a diagnosis of PA-IVS and we excluded those with an exclusively percutaneous treatment,patients lost or with insufficient follow-up and those affected by other arrhythmic syndromes.Surgical history and clinical outcomes were reviewed.Results:86 patients were included in the study(54 male[62.8%],mean age 16.4±6.1 years),with median follow-up from definitive repair of 12.8 years(6.4–18.9 years).They underwent three different final repairs:23 patients(26.7%)univentricular palliation,43(50%)biventricular correction,and 20(23.3%)one and a half ventricle correction.Thirteen patients(15%)developed arrhythmia:6 patients(all the subgroups)sinus node disfunction(SND);2(biventricular repair)premature ventricular complexes;2(one and a half ventricle repair)non-sustained ventricular tachycardia;1(biventricular repair)intra-atrial re-entrant tachycardia;1(one and a half ventricle repair)supraventricular tachyarrhythmia;1(biventricular repair)atrial fibrillation.Three patients with SND needed a pacemaker implantation.Only Fontan circulation showed an association with SND,while the other two groups heterogeneous types of arrhythmias.Conclusions:The low arrhythmic risk is related to surgical repair,it does not appear to be associated with native cardiomyopathy,and it appears to increase with length of follow up.Continuous follow-up in specialized centres is necessary to make an early diagnosis and to manage the potential haemodynamic impact at medium-long term.

文摘Background:Reversibility of pulmonary hypertension(PH)is closely related to the treatment options for and prognosis of children with congenital heart disease.Objective:We combined patient-specific clinical features including diagnosis,age and echocardiographic results,and biomarkers of pulmonary vascular dysfunction to explore the noninvasive methods that can be used to accurately evaluate the reversibility of pulmonary hypertension in congenital heart disease(PH-CHD).Methods:Based on the preoperative systolic pulmonary arterial pressure(sPAP),70 CHD patients were divided into normal,PH-CHD suspected,and confirmed groups.Additionally,biomarkers of circulating endothelial cells(CECs),endothelin-1(ET-1),and endothelial nitric oxide synthase(eNOS)were detected.Patients were categorized into reversible(RPH)and irreversible(IRPH)groups according to the sPAP 6 months after surgery.Risk stratification was performed according to the clinical features and biomarkers.Results:CECs and ET-1 levels in the confirmed group were significantly higher.eNOS was higher in the confirmed and suspected groups than that in the normal group.CECs in the IRPH group were significantly higher compared to the RPH group.No such intergroup differences were observed with respect to ET-1 and eNOS levels.The ROC curve showed that the risk stratification was of high diagnostic value to evaluate reversibility.Conclusion:The CECs,eNOS,and ET-1 were closely related with PH-CHD.CECs and risk stratification have high practical value in assessing the reversibility of PH-CHD.
文摘Objective In patients with pulmonary atresia and intact ventricular septum (PAIVS) without right ventricular-dependent coronaries,catheter techniques including the use of a sniff wire,lasers,and radiofrequency have been the most widely used as initial therapy. However,percutaneous perforation and balloon valvuloplasty were associated with higher rate of procedural failure and
文摘Objective Endothelin is a key role in the pathogenic of pulmonary arterial hypertension. High concentrations of endothelin 1 have been recorded in plasma and lungs of patients with pulmonary artery hypertension associated with congenital heart disease,and the concentrations of endothelin-1 was correlated with severity degree
文摘Background The reversibility of pulmonary arterial hypertension(PAH)in congenital heart disease(CHD)is of great importance for the operability of CHD.Proteomics analysis found that transgelin was significantly upregulated in the lung tissue of CHD-PAH patients,especially in the irreversible group.However,how exactly it participated in CHD-PAH development is unknown.
文摘We performed a retrospective analysis of patients with and without 22q11 deletion undergoing surgery for pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals between January 2004 and August 2009 at our institutions. Information was collected on collateral origin, arch sidedness, presence of central pulmonary arteries, and presence of an aberrant subclavian vessel. While patients with 22q11 deletion were more likely to have collateral origin from brachiocephalic vessels, patients without 22q11 deletion were more likely to have collateral origin from the descending aorta. There was no significant difference in arch sidedness or the presence of central pulmonary arteries. Patients with 22q11 deletion were more likely to have an aberrant subclavian artery (15/46 vs 5/54, p < 0.05), whether a left or right arch was present. Nine of the fifteen 22q11 deletion patients had a collateral originating from an aberrant subclavian artery. In time, genomic and embryologic research may help determine the exact mechanisms by which 22q11 deletion contributes to the development of congenital heart disease such as pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals.

文摘Objective To explore the correlation between endothelia cells activation and cytokines (ET-1, NO) levels in patients with pulmonary hypertension (PH), and to discuss their roles in the development of PH. Methods Twenty patients with simple ventricular septal defect (VSD) were chosen as controls, and 30 patients with PH were studied. Plasma levels of ET-1 and NO were measured by radioimmunoassay or colorimetric method. Before cardiopulmonary bypass was established, the specimens from right lung were fixed with formaldehyde solution, embedded with paraffin and stained by SP immunohistochemistry. Intercellular adhesion molecule-1 (ICAM-1) expression was measured through the determination of the light density with computer imaging technology. Results Compared with that of the patients with simple VSD, the light density of ICAM-1 and plasma level of ET-1 increased in patients with PH; but plasma level of NO decreased (P<0.05). Positive correlation was observed between ICAM-1 and ET-1/NO (P<0.05). Conclusion Endothelia cells activation and imbalance of ET-1/NO might play an important role in the development of PH.
文摘Purpose:This study examined the efficacy and safety of selexipag in treating pulmonary arterial hypertension(PAH)associated with congenital heart disease(CHD).Materials and Methods:We conducted a retrospective study of patients with CHD-associated PAH,treated with selexipag since December 2017.Thirteen adult patients(mean age,45.4 years;women,77%)were treated with selexipag as add-on therapy.Baseline characteristics,World Health Organization functional class,6-minute walking distance(6MWD)test results,N-terminal pro-B-type natriuretic peptide levels,echocardiographic data,and incidence of side effects were assessed.Results:The majority of patients(12/13,92.3%)experienced more than one treatment-associated complication;one patient dropped out of the study due to intolerable myalgia.The results of 6MWD test(from 299.2±56.2 m to 363.8±86.5 m,p=0.039)and tricuspid regurgitation(TR)pressure gradient(from 84.7±20.5 mmHg to 61.6±24.0 mmHg,p=0.018)improved and remained improved after selexipag treatment in 12 patients.Based on the results of a non-invasive risk assessment,8(66.7%)patients showed improvement,3(25.0%)showed no interval change,and the status of one patient(8.3%)deteriorated.Moreover,compared to patients treated with a low dosage,patients treated with a medium-to-high dosage showed a greater increase in 6MWD results(88.3±26.4 m vs.55.3±27.6 m,p=0.043)and a greater reduction in the TR pressure gradient(-33.7±10.9 mmHg vs.-12.5±12.0 mmHg,p=0.015).Conclusion:Selexipag is an efficient pulmonary vasodilator as add-on therapy in treating CHD-associated PAH.
文摘Congenital heart disease(CHD)-associated pulmonary arterial hypertension(PAH)includes a heterogeneous patient population that can be characterized by the underlying cardiac malformation.CHD-associated PAH has an estimated prevalence of 5– 10% in adult patients,with an increasing number of patients surviving to adulthood because of advances in the surgical management and the development of pulmonary arterial hypertension(PAH)-targeted pharmacotherapy.Although limited data exist,targeted PAH pharmacotherapy has proven to be benefi cial in patients with CHD-associated PAH,with observed improvement in functional class,increase in exercise capacity,and improvement in quality of life and cardiopulmonary hemodynamics.Additionally,there has been increasing interest in the“treat-to-close”strategy.PAH-targeted pharmacotherapy may be used to optimize cardiopulmonary hemodynamics so as to improve patients’operability in repairing the cardiac defect.Although there have been signifi cant advances in the management of this disease state in the past 2 decades,mortality remains high,and ongoing clinical trials are needed to better understand the treat-to-close strategy.
文摘Managing microtia patients is always a challenge. Multidisciplinary approach, good family support, well established doctorepatient relationship and well organised patient-support groups are the essential elements for success. With the advancement of implantable hearing devices,more options will be available for the microtia patients. Otologists play a leading role in the whole management process. They not only provide proper guidance to the patients in choosing the correct path of the treatment, but also play a key role in organising and maintaining a costeffective multidisciplinary rehabilitation team for the microtia patients.
文摘Aural atresia is a rare congenital malformation of the external and middle ear. There are several syndromic associations of this anomaly with those involving the first and second branchial arches. Occurrence of aural atresia with sclerosing skeletal dysplasia is unknown and has never been reported. The coexistence of a sclerosing dysplasia can make the surgical treatment in aural atresia difficult and risky; and the auditory improvement may not be as expected. Moreover, internal auditory canal narrowing and hence sensorineural hearing loss in sclerosing dysplasia might add to the already existing conductive hearing loss in such patients. In this case report we have described an unknown association of bilateral microtia with sclerosing skeletal dysplasia(autosomal dominant osteopetrosis) and clinical implications of these two conditions occurring together leading to a change in the management plan.
