Rheumatic mitral valve

INTRODUCTION: Infective endocarditis is a microbial infection of the endocardial surface of the native and prosthetic valves. This study aimed to evaluate knowledge regarding the current guidelines for antibiotic prophylaxis for infective endocarditis. METHODS: This cross-sectional study was conducted among physicians, cardiologists, and dentists in Rawalpindi and Islamabad. The questionnaire was distributed as Google Forms among the required population, and responses were collected on a Google Response Sheet...

Introduction : Handheld echocardiography (echo) is the tool of choice for rheumatic heart disease (RHD) screening. We aimed to assess the agreement between screening and standard echo for latent RHD diagnosis in schoolchildren from an endemic setting. Methods: Over 14 months, 3 nonphysicians used handheld machines and the 2012 WHF Criteria to determine RHD prevalence in consented schoolchildren from Brazilian low-income public schools. Studies were interpreted by telemedicine by 3 experts (Brazil, US). RHD-positive children (borderline/definite) and those with congenital heart disease (CHD) were referred for standard echo, acquired and interpreted by a cardiologist...

BACKGROUND: Rheumatic fever and rheumatic heart disease is endemic in India. Mitral valve replacement with mechanical valve is the commonest surgical procedure performed in rheumatic heart disease (RHD). However, there are no studies reporting the long-term outcomes of mechanical mitral valve replacement in rheumatic heart disease from India. OBJECTIVE: The primary objective of the study was to look at the long-term survival following mechanical mitral valve replacement in RHD...

BACKGROUND: Rheumatic carditis is the leading cause of permanent disability caused by damage of the cardiac valve. This study aimed to determine the outcome and predictors of valve surgery in patients with acute rheumatic fever (ARF) and recurrent rheumatic fever (RRF). METHODS: This was a retrospective study of patients diagnosed with ARF and RRF between 2006 and 2021. The predictors of valve surgery were analysed using multivariable Cox proportional regression...

Percutaneous balloon mitral valvotomy (PBMV) is a good and preferred therapy choice over surgical commissurotomy for patients with rheumatic mitral stenosis (MS). However, interventional cardiologists must recognize that treating patients with rheumatic MS poses unique challenges for each patient, especially in special populations such as pregnant patients or patients with arrhythmias like atrial fibrillation (AF), which can complicate procedures. Based on information from observational studies, PBMV may be a safe and efficient treatment for improving outcomes in MS women who do not have substantial subvalve illness in a specific demographic...

Most individuals with ventricular septal defect survive to adulthood which allows time for other complications such as pulmonary arterial hypertension to gradually develop over a period of time. When there are other associated cardiac conditions that also contribute to the development of pulmonary hypertension such as valvular heart disease, the pulmonary hypertension may be exaggerated. Because these different etiologies of the pulmonary hypertension have different mechanisms, their coexistence can complicate patient management...

INTRODUCTION: Primary cardiac myxomas are rare tumors. Concurrent valvular lesion is a common finding on evaluation which is thought to be due to annular dilatation secondary to tumor movement across the valve, functional obstruction across the valve, and severe pulmonary hypertension secondary to chronic obstruction. A common belief among surgeons is that excision of myxoma leads to abatement of symptoms, and further valve intervention may not be warranted. METHODS: A 10-year retrospective descriptive study was designed to analyze patients who underwent excision of cardiac myxoma at our center...

A 68-year-old male patient was admitted for extremities edema and diagnosed with infective endocarditis (IEIE). The patient underwent mitral and aortic valve mechanical valve replacement due to rheumatic heart valve disease 26 years ago. He underwent mechanical aortic valve and bioprosthetic tricuspid valve replacement due to mechanical aortic valve dysfunction and severe tricuspid valve regurgitation 1 year ago. Two months ago, the patient underwent emergency permanent pacemaker implantation due to syncope caused by a third-degree atrioventricular block...

BACKGROUND: When mitral valve (MV) surgery is indicated, repair is preferred over replacement; however, this preference is not supported by evidence from clinical trials. Furthermore, the benefits of MV repair may not be universal for all etiologies of MV disease.Methods and Results: This study identified a total of 18,428 patients who underwent MV repair (n=4,817) or MV replacement (n=13,611) during 2001-2018 from Taiwan's National Health Insurance Research Database. These patients were classified into 4 etiologies: infective endocarditis (IE, n=2,678), rheumatic heart disease (RHD, n=4,524), ischemic mitral regurgitation (IMR, n=3,893), and degenerative mitral regurgitation (DMR, n=7,333)...

BACKGROUND: Long-term invasive mechanical ventilation (IMV) is a major burden for those affected and causes high costs for the health care system. Early risk assessment is a prerequisite for the best possible support of high-risk patients during the weaning process. We aimed to identify risk factors for long-term IMV within 96 h (h) after the onset of IMV. METHODS: The analysis was based on data from one of Germany's largest statutory health insurance funds; patients who received IMV ≥ 96 h and were admitted in January 2015 at the earliest and discharged in December 2017 at the latest were analysed...

BACKGROUND: Rheumatic heart disease is the major cause of valvular heart disease in developing nations. Endothelial cells (ECs) are considered crucial contributors to rheumatic heart disease, but greater insight into their roles in disease progression is needed. METHODS: We used a Cdh5 -driven EC lineage-tracing approach to identify and track ECs in the K/B.g7 model of autoimmune valvular carditis. Single-cell RNA sequencing was used to characterize the EC populations in control and inflamed mitral valves...

BACKGROUND: Mitral valve (MV) disease is the most common form of valvular heart disease. Findings that indicate women have a higher risk for unfavorable outcomes than men remain controversial. This study aimed to determine the sex-based differences in epidemiological distributions and outcomes of surgery for MV disease.Methods and Results: Overall, 18,572 patients (45.3% women) who underwent MV surgery between 2001 and 2018 were included. Outcomes included in-hospital death and all-cause mortality during follow up...

OBJECTIVE: We aimed to evaluate the mitral valve calcification and mitral structure detected by cardiac computed tomography (cardiac CT) and establish a scoring model based on cardiac CT and clinical factors to predict early good mitral valve repair (EGMR) and guide surgical strategy in rheumatic mitral disease (RMD). MATERIALS AND METHODS: This is a retrospective bi-center cohort study. Based on cardiac CT, mitral valve calcification and mitral structure in RMD were quantified and evaluated...

OBJECTIVES: We evaluated practice trends and 3-year outcomes of transcatheter edge-to-edge repair (TEER) and surgical repair for degenerative mitral regurgitation (MR) in the U.S. METHODS: From the Centers for Medicare and Medicaid data (2012-2019), 53,117 mitral valve interventions (surgery or TEER) were performed for degenerative MR, identified by excluding rheumatic and congenital disease, endocarditis, myocardial infarction, cardiomyopathy, and concomitant or prior coronary revascularizations...

BACKGROUND: Identification of children with latent rheumatic heart disease (RHD) by echocardiography, before onset of symptoms, provides an opportunity to initiate secondary prophylaxis and prevent disease progression. There have been limited artificial intelligence studies published assessing the potential of machine learning to detect and analyze mitral regurgitation or to detect the presence of RHD on standard portable echocardiograms. METHODS AND RESULTS: We used 511 echocardiograms in children, focusing on color Doppler images of the mitral valve...

INTRODUCTION: Mitral valve repair (MVr) has been shown to achieve better outcomes than mitral valve replacement (MVR) in degenerative aetiology. However, that cannot be applied in rheumatic mitral valve disease. Therefore, this study aims to evaluate early and late clinical outcomes and mid-term survival in RHD compared to the non-RHD group and whether mitral valve repair is a better surgical approach in RHD patients. METHODS: Patients who underwent mitral valve surgery with or without coronary artery bypass grafting were included in this study...

This case report discusses the rare coexistence of Systemic Lupus Erythematosus (SLE) and Rheumatic Heart Disease (RHD) in a 46-year-old female patient, challenging the conventional understanding of their distinct presentations. The patient exhibited migratory joint pains, palpitations, and shortness of breath. Diagnostic investigations confirmed SLE based on EULAR/ACR criteria, with positive anti-nuclear and anti-dsDNA antibodies. Concurrently, transthoracic echocardiography revealed severe mitral stenosis and regurgitation, leading to the diagnosis of RHD...

A 51-year-old female underwent emergency mitral valve replacement for mitral stenosis with an undetermined mass which was attached to the anterior mitral leaflet. Histopathological testing of the excised specimen confirmed the diagnosis of rheumatic mitral disease in combination with a primary rhabdomyosarcoma. Postoperative adjuvant chemotherapy with pazopanib hydrochloride was given. At 10 months of follow-up, repeated computed tomographic screening has not shown any signs of local recurrence or secondary metastases...
