Advances in the pathogenesis and ultrasonic diagnosis of senile calcific valvular disease of the heart

Objective:Senile calcific valvular disease of the heart is an endemic valvular heart disease in the elderly patients. The disease is mainly characterized by degenerative change, thickening, fibrosis and calcification of the valvular connective tissue, which leads to the dysfunction of the valve and its stent. The pathogenesis of calcified valvular heart disease has not been fully elucidated, and it may be related to hemodynamics, atherosclerosis and sex. Echocardiography is the basic method and important basis for clinical diagnosis of calcified valvular heart disease, and it might detect the valvular thickening or calcification. This article aimed to analyze the pathogenesis of senile calcified valvular heart disease. At the same time, this research tried to review the progress on ultrasonic diagnosis of senile calcified valvular heart disease in order to provide references for clinical diagnosis and treatment.

The Problem of Rehospitalisation for Heart Failure at the Cardiology Department of the Hôpital National Ignace Deen

Introduction: Despite current therapeutic advances, heart failure in sub-Saharan Africa remains a common, serious and costly disease, particularly due to rehospitalizations. The objective of this work was to determine the proportion of rehospitalizations for heart failure and to identify etiological factors. Methodology: This was a retrospective descriptive study with a duration of 8 months from April 1 to November 30, 2021. This study included all patients rehospitalized in the department for Heart Failure and who agreed to participate in our study. Results: During the period of our study, 437 patients were hospitalized in the HF department, among which we collected 126 cases of rehospitalization for HF with a frequency of 28.83%. The mean age of our patients was 46.32 ± 18.98 years with the extremes of 15 to 84 years. The most affected age group was between 35 and 44 years old in 24 cases, i.e. a frequency of 19%. We observed a female predominance of 64 cases, i.e. a frequency of 50.8% compared to 62 cases, i.e. a frequency of 49.2% with a sex ratio (M/F) equal to 0.96. 98 cases of our patients, i.e. a frequency of 77.8%, were mutual insurance companies who felt they had the necessary support from those around them. In our sample, the underlying heart disease was mainly represented by valvular heart disease in 59 cases, followed by hypertensive heart disease in 42 cases with the respective frequencies of 46.82% and 33.33%. The majority of our patients were rehospitalized (1 - 3) times after a first episode of HF flare-up in 117 cases or 92.9%. Irregularity at control and therapeutic break were the most common decompensation factors with frequencies of 75.8% and 74.2% respectively. The majority of our patients were rehospitalized (1 - 3) times after a first episode of HF flare-up in 117 cases or 92.9%. Irregularity at control and therapeutic break were the most common decompensation factors with frequencies of 75.8% and 74.2% respectively. Conclusion: It appears in this study that rehospitalizations for heart failure are frequent, linked to irregularity in control and the lack of therapeutic education.

Clinical, sonographic characteristics and long-term prognosis of valvular heart disease in elderly patients

Background Valvular heart disease(VHD)is expected to become more prevail as the population ages and disproportionately affects older adults.However,direct comparison of clinical characteristics,sonographic diagnosis,and outcomes in VHD patients aged over 65 years is scarce.The objective of this study was to evaluate the differences in clinical characteristics and prognosis in two age-groups of geriatric patients with VHD.Methods We retrospectively enrolled consecutive individuals aged>65 years from Guangdong Provincial Peopled Hospital and screened for VHD using transthoracic echocardiography(TTE)or transesophageal echocardiography(TEE).Finally,260(48.9%)patients were in the 65-74 years group,and 272(51.1%)were in the>75-year group.Factors that affected long-term survival was explored.A multivariable Cox hazards regression was performed to identify the predictors of major adverse cardiac events(MACEs)in each group.Results In our population,the older group were more likely to have chronic obstructive pulmonary disease(COPD),degenerative VHD,but with less rheumatic VHD,aortic stenosis(AS)and mitral stenosis(MS).Compared with those aged 65-74 years,the older group had a higher incidence of all-cause death(10.0%vs.16.5%,P=0.027),ischemic stroke(13.5%vs.20.2%,P=0.038)and MACEs(37.3%vs.48.2%,P=0.011)at long-term follow-up.In multivariable Cox regression analysis,mitral regurgitation,a history of COPD,chronic kidney disease,diabetes,hypertension,atrial fibrillation and New York Heart Association(NYHA)functional class were identified as independent predictors of MACEs in the older group.Conclusion Advanced age profoundly affect prognosis and different predictors were associated with MACEs in geriatric patients with VHD.

Differences in the predictive value of red cell distribution width for the mortality of patients with heart failure due to various heart diseases

Background Increased red blood cell distribution width （RDW） is associated with adverse outcomes in patients with heart failure （HF）. The objective of this study was to compare the differences in the predictive value of RDW in patients with HF due to different causes. Methods We retrospectively investigated 1,021 HF patients from October 2009 to December 2011 at Fuwai Hospital （Beijing, China）. HF in these patients was caused by three diseases; coronary heart disease （CHD）, dilated cardiomyopathy （DCM） and valvular heart disease （VHD）. Patients were followed-up for 21 ~ 9 months. Results The RDW, mortality and survival duration were significantly different among the three groups. Kaplan-Meier analysis showed that the cumulative survival decreased significantly with increased RDW in patients with HF caused by CHD and DCM, but not in those with HF patients caused by VHD. In a multivariable model, RDW was identified as an independent predictor for the mortality of HF patients with CHD （P 〈 0.001, HR 1.315, 95% CI 1.122-1.543）. The group with higher N-terminal pro-brain natriuretic peptide （NT-proBNP） and higher RDW than median had the lowest cumulative survival in patients with HF due to CHD, but not in patients with HF due to DCM. Conclusions RDW is a prognostic indicator for patients with HF caused by CHD and DCM; thus, RDW adds important information to NT-proBNP in CHD caused HF patients.

Bioinformatics Analysis on lncRNA and mRNA Expression Profiles for Novel Biological Features of Valvular Heart Disease with Atrial Fibrillation

The biological features of the valvular heart disease with atrial fibrillation(AF-VHD)remain unknown when involving long non-coding RNAs(lncRNAs).This study performed system analysis on lncRNA and messenger RNA(mRNA)expression profiles constructed by using bioinformatics methods and tools for biological features of AF-VHD.Fold change and t-test were used to identify differentially expressed(DE)lncRNAs and mRNAs.The enrichment analysis of DE mRNAs was performed.The subgroups formed by lncRNAs and nearby mRNAs were screened,and a transcriptional regulation network among lncRNAs,mRNAs,and transcription factors(TFs)was constructed.The interactions between mRNAs related to lncRNAs and drugs were predicted.The 620 AF-VHDrelated DE lncRNAs and 452 DE mRNAs were identified.The 3 lncRNA subgroups were screened.The 665 regulations mediated by lncRNAs and TFs were identified.The 9 mRNAs related to lncRNAs had 1 or more potential drug interactions,totaling 37 drugs.Of these,9 drugs targeting 3 genes are already known to be able to control or trigger atrial fibrillation(AF)or other cardiac arrhythmias.The found biological features of AF-VHD provide foundations for further biological experiments to better understand the roles of lncRNAs in development from the valvular heart disease(VHD)to AF-VHD.

One Case of Diabetes Nephropathy Stage V, Combined Valvular Disease, Total Heart Failure with Diabetes Foot Gangrene

The patient was found to have 4+urine sugar by physical examination 14 years ago and was treated with oral hypoglycemic drugs. Insulin was injected intramuscularly nine years ago. Two and a half years ago, it was found that the color of the thumb, index and middle toe of the left foot became black. He went to a third-class hospital in Beijing and was diagnosed as “diabetes foot”. He was treated with “balloon dilation of lower limb blood vessels of diabetes foot”. Half a year ago, the third toe on the right side was broken and treated in the hospital again. “Popliteal artery stent implantation” was given for the diagnosis of “double kidney insufficiency, diabetes foot, left heart failure, combined heart valve disease”, “Hemofiltration therapy” and anti-inflammatory, amino acid supplementation, kidney function protection, anticoagulation, anemia correction and other treatments. Later, he went to our hospital and was diagnosed by the TCM diagnosis: category of consumptive disease, toe or finger gangrene (syndrome/pattern of qi and yin deficiency). Western medicine diagnosed: stage V of diabetes nephropathy, type II diabetes foot gangrene, combined with heart valve disease, hypoalbuminemia, double kidney cyst, moderate anemia, pleural effusion, hyperkalemia, pulmonary infection, and total heart failure. The patient was treated by the Qi-acupuncture therapy of TCM in combination with Chinese and Western medicine Medical treatment made the patient significantly better and discharged.

Heart valve disease in elderly Chinese population： effect of advanced age and comorbidities on treatment decision-making and outcomes

Background A considerable proportion of elderly patients with symptomatic severe heart valve disease are treated conservatively de- spite clear indications for surgical intervention. However, little is known about how advanced age and comorbidities affect treatment deci-sion-making and therapeutic outcomes. Methods Patients （n = 234, mean age： 78.5 ± 3.7 years） with symptomatic severe heart valve dis- ease hospitalized in our center were included. One hundred and fifty-one patients （65%） were treated surgically （surgical group） and 83 （35%） were treated conservatively （conservative group）. Factors that affected therapeutic decision-making and treatment outcomes were investi- gated and long-term survival was explored. Results Isolated aortic valve disease, female sex, chronic renal insufficiency, aged _〉 80 years, pneumonia, and emergent status were independent factors associated with therapeutic decision-making. In-hospital mortality for the surgical group was 5.3% （8/151）. Three patients （3.6%） in the conservative group died during initial hospitalization. Low cardiac output syndrome and chronic renal insufficiency were identified as predictors of in-hospital mortality in the surgical group. Conservative treatment was identi- fied as the single risk factor for late death in the entire study population. The surgical group had better 5-year （77.2% vs. 45.4%, P 〈 0.0001） and 10-year （34.5% vs. 8.9%, P 〈 0.0001） survival rates than the conservative group, even when adjusted by propensity score-matched analysis. Conclusions Advanced age and geriatric comorbidities profoundly affect treatment decision-making for severe heart valve disease. Valve surgery in the elderly was not only safe but was also associated with good long-term survival while conservative treatment was unfavorable for patients with symptomatic severe valve disease.

Initial Experience in the Surgical Management of Valvular Heart Diseases at Yaoundé General Hospital: Preliminary Results

Introduction: Valvular heart diseases, often linked to rheumatic heart disease, represent a major cause of cardiovascular morbidity in sub-Saharan Africa. This study reports the preliminary outcomes of surgical treatment for valvular heart diseases initiated at the Yaoundé General Hospital (YGH) by an entirely local team. Materials and Methods: Between September 2022 and November 2024, 37 patients underwent surgery for valvular heart diseases at YGH. A retrospective analysis of clinical, operative, and postoperative data was conducted using R software (version 4.4.0). Results: Male patients predominated, with a sex ratio of 1.17. The median age at the time of surgery was 40 years (interquartile range [IQR]: 25.0 - 51.0). Dyspnea was the main symptom at admission, reported in 36 patients (97.3%). Rheumatic etiologies were the most frequent (25 cases, 67.57%), followed by atherosclerotic lesions (6 cases, 16.2%) and degenerative lesions (4 cases, 10.83%). Among the 37 patients, 19 (51.4%) underwent mitral valve replacement, 11 (29.7%) aortic valve replacement, 6 (16.2%) double mitral-aortic valve replacement, and 1 (2.7%) tricuspid valve replacement. Mechanical prostheses were implanted in 27 patients (73%), while 10 patients (27%) received biological prostheses. The median duration of cardiopulmonary bypass and aortic clamping was 101 minutes (IQR: 84.75 - 146.25) and 73 minutes (IQR: 55.75 - 116.25), respectively. The median duration of mechanical ventilation and ICU stay were 2 hours (IQR: 2 - 3) and 3 days (IQR: 2 - 4), respectively. The most frequent complication was postoperative anemia requiring blood transfusion in 16 patients (43.2%). Three patients (8.1%) required reoperation for bleeding. There was no in-hospital mortality. Conclusion: Valvular heart diseases treated at YGH are predominantly of rheumatic origin. Valve replacement was by far the most commonly used technique. Early outcomes are satisfactory and encouraging.

Assessing the Association between Heart Attack, High Blood Pressure, and Heart Disease Mortality Rates and Particulate Matter and Socioeconomic Status Using Multivariate Geostatistical Model

This study addresses the public concerns of potential adverse health effects from ambient fine particulate matter as well as socioeconomic factors. Heart attack, high blood pressure, and heart disease mortality rates were investigated against fine particulate matter and socioeconomic status, for all counties in the United States in 2013. Multivariate multiple regressions as well as multivariate geostatistical predictions show that these are significant factors towards assessing the causal inferences between exposure to air pollution and socioeconomic status and the three mortality rates.

Valvular Heart Disease and Aortic Dilatation

The case presented here offers us an opportunity to discuss an increasingly commonly confronted clinical challenge.Two issues are raised:how best to manage the patient’s valvular heart disease,including both the indications for surgical intervention and the prosthetic options,and how best to manage his aortic dilatation.Let us take them one at a time.The patient has severe aortic regurgitation but a normal ejection fraction.Although we do not have his ventricular dimensions,he has a class I indication for intervention given his symptoms.

Rheumatic valvular heart disease treated with traditional Chinese medicine:A case report

BACKGROUND Rheumatic heart disease(RHD)is an autoimmune disease that leads to irreversible valve damage and heart failure.Surgery is an effective treatment;however,it is invasive and carries risks,restricting its broad application.Therefore,it is essential to find alternative nonsurgical treatments for RHD.CASE SUMMARY A 57-year-old woman was assessed with cardiac color Doppler ultrasound,left heart function tests,and tissue Doppler imaging evaluation at Zhongshan Hospital of Fudan University.The results showed mild mitral valve stenosis with mild to moderate mitral and aortic regurgitation,confirming a diagnosis of rheumatic valve disease.After her symptoms became severe,with frequent ventricular tachycardia and supraventricular tachycardia>200 beats per minute,her physicians recommended surgery.During a 10-day preoperative waiting period,the patient asked to be treated with traditional Chinese medicine.After 1 week of this treatment,her symptoms improved significantly,including resolution of the ventricular tachycardia,and the surgery was postponed pending further follow-up.At 3-month follow-up,color Doppler ultrasound showed mild mitral valve stenosis with mild mitral and aortic regurgitation.Therefore,it was determined that no surgical treatment was required.CONCLUSION Traditional Chinese medicine treatment effectively relieves symptoms of RHD,particularly mitral valve stenosis and mitral and aortic regurgitation.

Noninvasive Surrogates for Left Ventricular Filling Pressure in Patients with Valvular Heart Disease

Background: Invasive measurement of left ventricular filling pressure is the gold standard for determining diastolic dysfunction and predicting subsequent outcomes. For repetitive assessment of diastolic function during long-term management, noninvasive surrogates are used. Their reliability and reproducibility should be validated separately for different cardiovascular diseases and conditions. The aim of this study was to identify noninvasive surrogates of invasively derived left ventricular filling pressure and to relate these surrogates to outcomes (death or valve replacement) in patients with stable, asymptomatic valvular heart disease and preserved ejection fraction. Materials and Methods: In a first cohort, we investigated 54 patients who had spiroergometry, echocardiography, and left heart catheterization within a range of 100 days. In a second cohort (n = 64), noninvasive measures were related to outcomes after follow-up of 694 ± 576 days. Transmitral doppler E/tissue doppler E’ (E/E’), E/flow propagation velocity (E/Vp), isovolumetric relaxation time/time to E’-time to E (IVRT/TE’-TE), ventilatory efficiency (VE/VCO2slope), O2 consumption at anaerobic threshold and at peak exercise (VO2AT, VO2peak) as well as NT-pro brain natriuretic peptide (NTpro-BNP) were assessed in relation to left ventricular filling pressure and outcome. Results: NT-proBNP, VO2AT, VE/VCO2slope as well as echocardiographic surrogates E/E’ and E/flow propagation velocity were indicators of elevated end diastolic filling pressure. In multivariable analysis, VO2AT was the only independent predictor. NT-proBNP was the only surrogate of left ventricular filling pressure which predicted outcome. Conclusion: In patients with asymptomatic valvular heart disease and preserved systolic function, spiroergometric parameters and NT-proBNP performed best to assess filling pressure. Only NT-proBNP showed prognostic value in this cohort.

Anesthetic management of a child with Cornelia de Lange Syndrome undergoing open heart surgery:A case report

BACKGROUND Cornelia de Lange syndrome(CdLS)is a congenital multisystemic genetic disorder.The expected lifespan of children with this disorder has been prolonged in parallel with the advances in medicine in recent years.However,they still more frequently undergo cardiac surgery.There are some challenges for clinicians when faced with CdLS patients.We present the perioperative management of a child with CdLS undergoing open-heart surgery.CASE SUMMARY Severe pulmonic and subpulmonic valvular stenosis,enlargement of the right side of the heart,mild tricuspid regurgitation,atrial septal defect,and patent ductus arteriosus were diagnosed in a 14-month-old boy with manifested cyanosis,developmental delay,and malnutrition.Attempted balloon valvuloplasty was unsuccessful due to a severe stenotic pulmonary valve,therefore it was decided to perform an open surgical repair.Following a successful and uncomplicated intraoperative course,the patient was extubated on postoperative day 5,and adrenalin and dopamine infusions were gradually decreased and stopped on postoperative days 6 and 10,respectively.Moderate laryngomalacia and suboptimal vocal cord movements were diagnosed,and tracheotomy and percutaneous endoscopic gastrostomy were performed under general anesthesia in the same session at postoperative day 32.The patient was discharged on postoperative day 85 after a challenging postoperative period with additional airway and nutritional problems.CONCLUSION This is the first report of the perioperative anesthetic and clinical management of a CdLS patient undergoing open-heart surgery.

Study of Coronary Artery Disease in Single Aortic Valvular Disease

Objectives To analyze the results of coronary angiographies (CAG) in patients with single aortic valvular heart disease; To study the relationship between aortic valve diseases and coronary artery disease (CAD). Methods 105 patients with single aortic valvular heart disease before surgery underwent angiography. The data of clinical characteristics and angiographies were analyzed. Results 51 patients had symptoms of angina pectoris among 105 patients with single aortic valvular heart disease. Seven of them were confirmed coronary artery disease by angiographies. Although the incidence of angina in aortic valve stenosis group was significantly higher than that in aortic valve regurgitation, the probability of combination of CAD in aortic valve stenosis group was similar to the later. However, the probability of combination of CAD in degenerative aortic valve group was significantly higher than the groups of rheumatic, congenitally bicuspid aortic valves, and other causes (p < 0.01 ). Conclusions Angina pectoris is not sensitive for diagnosis of CAD in single aortic valve heart disease. The probability of combination of CAD in degenerative aortic valve disease is higher than that in aortic valve disease with other causes. Coronary angiography is strongly suggested for these patients.

Risk of cardiovascular,cardiac and arrhythmic complications in patients with non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease(NAFLD)has emerged as a public health problem of epidemic proportions worldwide.Accumulating clinical and epidemiological evidence indicates that NAFLD is not only associated with liver-related morbidity and mortality but also with an increased risk of coronary heart disease(CHD),abnormalities of cardiac function and structure(e.g.,left ventricular dysfunction and hypertrophy,and heart failure),valvular heart disease(e.g.,aortic valve sclerosis)and arrhythmias(e.g.,atrial fibrillation).Experimental evidence suggests that NAFLD itself,especially in its more severe forms,exacerbates systemic/hepatic insulin resistance,causes atherogenic dyslipidemia,and releases a variety of pro-inflammatory,pro-coagulant and pro-fibrogenic mediators that may play important roles in the pathophysiology of cardiac and arrhythmic complications.Collectively,these findings suggest that patients with NAFLD may benefit from more intensive surveillance and early treatment interventions to decrease the risk for CHD and other cardiac/arrhythmic complications.The purpose of this clinical review is to summarize the rapidly expanding body of evidence that supports a strong association between NAFLD and cardiovascular,cardiac and arrhythmic complications,to briefly examine the putative biological mechanisms underlying this association,and to discuss some of the current treatment options that may influence both NAFLD and its related cardiac and arrhythmic complications.

TLR2 was overexpressed independent of IL-6 in patients with valvular atrial fibrillation

Toll-like receptor 2 （TLR2） has recently been shown to be up-regulated in patients with non-valvular atrial fi-brillation （AF）. The present study was aimed to determine whether the pathogenesis and development of AF is associated with the up-regulation of TLR2. Clinical data and right atrial appendage （RAA） specimens were col-lected from 20 patients with persisten AF （PeAF）, 15 patients with paroxysmal AF （PaAF） and 13 patients with no history of AF undergoing valvular replacement. The results showed that gene expression and protein content of TLR2 were increased in both the AF subgroups, compared with the sinus rhythm （SR） group. Between the two AF subgroups, PaAF had a higher TLR2 level than PeAF. However, no difference in interluekin （IL）-6 content was found among the three groups, and no correlation was found between TLR2 and IL-6 in PeAF patients （r = 0.090, P = 0.706）, PaAF patients （r = 0.408, P = 0.131） and AF patients （r = -0.301, P = 0.079）. Immunohistochemical analysis revealed that TLR2 was distributed in RAAs of AF patients and confirmed the immunoblotting results. In conclusion, we demonstrated that TLR2 was elevated in AF （especially PaAF） patients with valvular heart disease, further implicating inflammation involved in the pathogenesis and development of AF.

Pattern of Cardiovascular Diseases as Seen in an Out-Patient Cardiac Clinic in Ghana

Cardiovascular diseases (CVDs) are increasingly emerging as a major health problem in sub-Saharan Africa, but information on the epidemiology, clinical characteristics and spectrum of the diseases are scanty. Epidemiological data regarding the incidence and prevalence of CVDs in different geographical regions are essential to our understanding of global distribution and evolution of CVDs. We conducted a retrospective observational study to determine the prevalence and spectrum of cardiovascular diseases in patients seen at the out-patient cardiac clinic of the Directorate of Medicine, Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. Medical records of 432 patients selected from the cardiac clinic using simple random sampling. The medical history, including the socio-demographic information, was examined. The results of the patients’ laboratory tests, chest X-ray, electrocardiography, M-mode and two-dimensional echocardiography with Doppler and colour flow imaging of the patients were also examined. The patients were aged between 13 - 97 years with the mean age (±standard deviation) of 55.35 (±19) years. There were more females (53%;n = 229) than males (47%;n = 203). The main cardiovascular diseases seen included: hypertensive heart disease (35.6%;n = 154), valvular heart disease (19.7%;n = 85), cardiomyopathies (18.5%;n = 80), arrhythmias (6.3%;n = 27) and coronary artery disease (4.2%;n = 18). The most common causes of valvular heart disease, cardiomyopathies and arrhythmias were rheumatic heart disease, dilated cardiomyopathy and complete heart block respectively. In conclusion, our study has shown that hypertensive heart disease, rheumatic heart disease and cardiomyopathies were the main cardiovascular diseases,seen in 73.8% of the patients in this study.

Epidemiological survey of valvular heart disease for five years in a single cardiovascular center of Southern China: Changes in morbidity, etiological spectrum and management

Background Valvular heart disease （VHD） is defined as a structural or functional abnormality in cardiac valve which encompasses a number of common cardiovascular conditions. This study was aimed to analyze the epidemiological changes of VHD in a single cardiovascular center of Southern China. Methods A total of 13,138 VHD patients of Guangdong general hospital from January 2011 to December 2013 were screened by transthoracic echocardiography （TTE） or transesophageal echocardiography （TEE） and enrolled for this study. The morbidity, etiological spectrum and management of these patients were analyzed. Continuous variables were expressed as mean _＋ standard deviation. Categorical variables were expressed as ratio or percentage. Results Patients in this study were divided into different groups and were analyzed throughout changes in morbidity, etiological spectrum and management. Conclusions The prevalence of VHD remains high in Southern China and RHD is still the leading etiology of VHD. But morbidity rate is reduced and surgery is still the main treatment option.

Current Status and Challenges of Valvular Heart Disease Interventional Therapy

Valvular heart disease(VHD)is common in the global population,occupying an heavy disease burden among aging population.Currently,it is the booming era of transcatheter VHD treatment,even with superiority than traditional open heart surgery in some clinical outcomes.We collected data sources mainly derived from published articles and conference presentations,including randomized controlled trials,first-in-man studies,clinical registries,and other single-or multi-center and prospective or retrospective clinical studies.This review summarized the relevant devices and researches of transcatheter aortic valve replacement,transcatheter mitral valve repair and replacement,transcatheter tricuspid valve repair and replacement,and transcatheter pulmonary valve replacement.Moreover,possible challenges of interventional therapy for various VHD in the future were discussed as well.
