Non-obstetrical drivers of adverse pregnancy outcomes are underappreciated. Latent structural heart disease may account for a substantial proportion of adverse pregnancy outcomes in low-resource settings. Pregnant women presenting to B.P. Koirala Institute of Health Sciences will be prospectively included into a registry upon their visit for antenatal care. Women will be followed until 6 weeks after the time of delivery. Nested within this registry, the investigators will perform a registry-based adaptive cluster randomized crossover trial. The trial compares an experimental condition (echocardiographic screening) and a control condition (routine antenatal care).

GOAL-Stop is a randomized, controlled, non-inferiority trial designed to evaluate whether discontinuing secondary antibiotic prophylaxis (SAP) is non-inferior to continuing SAP in preventing progression of rheumatic heart disease (RHD) among children and adolescents. The trial will enroll participants aged 5-20 years with previously diagnosed mild RHD who have received at least 2 years of SAP and who demonstrate either echocardiographic normalization or stability (persistent mild RHD). Participants will be randomized to either continue SAP or discontinue SAP for 2 years. The primary outcome is echocardiographic progression of RHD at 2 years, assessed by blinded adjudicators using the 2023 World Heart Federation criteria. Subgroup analyses will evaluate outcomes in participants with echocardiographic normalization versus stable mild RHD, and an exploratory analysis will assess whether outcomes differ by prior prophylaxis route (oral vs. intramuscular).
NCT05211024
GOAL-Post is comprised of two studies that will help refine recommendations for the duration of secondary prophylaxis for children diagnosed with latent RHD, which is currently not known
NCT05502042
The objective of CAMPS is to test and evaluate scalable models of secondary antibiotic adherence support for children newly diagnosed with rheumatic heart disease. Aim 1: Determine 1-year BPG adherence rates of children newly diagnosed with latent RHD in Uganda randomized to two support strategies: (1) Usual care (Arm 1) (2) peer group + case manager strategy (Arm 2). Aim 2: Explore patient reported outcomes including treatment satisfaction, patient health-related quality of life, and care giver quality of life, in relation to support strategy and adherence.
NCT05991219
After basic clinical screening including history and physical, Point of care ultrasound will be performed to look at Mitral, Aortic and Tricuspid Valves for regurgitation or stenosis. For patients with confirmed Rheumatic heart disease (RHD), treatment and referral depending on stage of disease. Antibiotic prescription could be shifted to community health workers delivering preventive medications via practical clinical algorithms, diagnostic tools, availability of appropriate antibiotics, and supportive supervision. Patients will have repeat imaging at 2 years and 5 years to look at the outcome of delayed progression of valve disease.
NCT04575857
The goal of this study is to address specific implementation questions necessary and sufficient to ensure the feasibility of the larger randomized trial examining the efficacy of statin medications in slowing rheumatic heart disease (RHD) valvular pathology progression. This feasibility study is intended to confirm the number of readily recruitable subjects, assess recruitment rate, and assess the rate of valve pathology via echocardiograms. These results are necessary and sufficient to facilitate the successful design of a large full scale randomized trial to determine whether statins improve outcomes in RHD. Successful treatment of RHD would fundamentally shift the RHD management paradigm world-wide, improve the lives of millions afflicted with RHD, and subsequently, decrease health care spending on RHD management.
NCT05618223
Rheumatic mitral stenosis remains a health problem in developing countries. Progressive fibrosis of the valves and myocardium is the main pathophysiology that plays an important role. Dapagliflozin has various beneficial effects on the heart by reducing fibrosis, reducing inflammation, and improving patient quality of life. However, the role of this therapy is unknown in patients with rheumatic mitral stenosis.
NCT02832531
This program is a comprehensive evaluation of rheumatic valvular heart disease (RVHD), Atrial fibrillation (AF)/flutter and stroke. A prospective, randomized, open-label superiority trial comparing rivaroxaban to aspirin in high risk patients either with AF and unsuitable for VKA or without AF and with high risk factors.
NCT03346525
Rheumatic heart disease (RHD) affects at least 32.9 million people, mostly children living in low-resource settings. Long-term intramuscular benzathine penicillin G (BPG) prophylaxis is proven to prevent progression of chronic valve changes in patients with established rheumatic heart disease (RHD) and to allow regression of valve changes in patients with a history of acute rheumatic fever (ARF) with mild RHD. However, in low-resource settings ARF is an elusive diagnosis, and most patients (85%) are diagnosed only when RHD is severe and irreversible, medications ineffective, and surgical intervention is expensive and/or unavailable. Identification of latent RHD might be an opportunity to substantially reduce RHD morbidity and mortality. However, detection of latent RHD is only important if outcomes are improved. The appropriate management of children with latent RHD is unknown and no formal recommendations exist. While some clinicians prescribe penicillin prophylaxis for children with latent RHD, clinical equipoise exists regarding the best practice. To fill this gap, the investigators propose a randomized controlled trial in children with latent RHD to evaluate the efficacy of BPG prophylaxis compared to no prophylaxis. Our primary outcome measure is progression of valvular changes on echocardiogram at 2 years. A sample size of 916 children is needed to detect a 50% reduction of progression (expected range 7.5-12.5% progression in BPG-arm vs. 15%-25% progression in control-arm) with 90% power. AIM 1: To compare the proportion of children (aged 5-17 years) with latent RHD receiving BPG prophylaxis who progress to worse valvular disease at 2-years compared to children not receiving BPG prophylaxis. Hypothesis 1: Prophylaxis with BPG will result in fewer children with latent RHD showing progression of echocardiographic valve changes at 2 years compared to children with latent RHD not receiving BPG prophylaxis. (The investigators expect at least a 50% relative reduction in progression in the BPG arm: range 15%-25% control arm vs. 7.5-12.5% BPG-arm.) AIM 2: To compare the proportion of children (aged 5-17 years) with latent RHD receiving BPG prophylaxis who regress to improved valvular disease at 2-years compared to children not receiving BPG prophylaxis. Hypothesis 2: Prophylaxis with BPG will result in more children with latent RHD showing regression of echocardiographic valve changes by 2 years compared to children with latent RHD not receiving BPG prophylaxis. (The investigators expect at least a 50% relative increase in regression in the BPG arm: range 10-20% control arm vs. 20-40% BPG arm.) This study is highly significant because it will establish if BPG prophylaxis improves outcomes for children with latent RHD. Feasibility will be ensured through the experience, resources, community support, and accessible patient population of our investigational team. The results of our study will have high impact, immediately informing international policy on the standard of care for children diagnosed with latent RHD and shaping, over 2-3 years, practical and scalable programs that could substantially decrease the global burden of RHD.

Rheumatic heart disease remains a major health problem in developing countries. It is the most important sequel of rheumatic fever and occurs in about 30% of patients with rheumatic fever.Rheumatic heart disease presents with different degrees of pancarditis and associated valve failure. Involvement of the mitral leaflets can cause mitral regurgitation (MR) or stenosis and eventually can lead to heart failure. Mitral repair or replacement is therefore recommended before left ventricular (LV) dysfunction develops. Study Objectives/Specific Aims Overall Goal: To determine the benefit the patient with pulmonary hypertension will get from mitral valve replacement as regard function improvement and remodeling of the right ventricle. * Objective1: Identify risk factors that are predictive of outcomes.(Type and severity of Mitral valve pathology , severity of pulmonary hypertension, tricuspid regurge, preoperative RV dysfunction) * Objective2: Determine the value of management strategies (Mitral valve replacement in pulmonary hypertension i.e. : decrease RV pressure overload and enhance RV remodeling) * Objective3: Assessment of the outcomes clinically \& Echocardiographically : postoperative results during hospital stay and follow up (short term up to 3 months).

This study evaluates the safety and efficiency of surgical prevention of atrial fibrillation in patients with valvular heart disease and left atrium enlargement
NCT02353663
Rheumatic heart disease remains a major challenge in low and middle income countries. Early detection of clinically silent valvular lesions by screening echocardiography allows timely implementation of secondary antibiotic prevention, and may prevent progression of disease to severe valvular damage and heart failure. The objective of the study is to assess the prevalence of rheumatic heart disease among schoolchildren in Arequipa, Peru. Subsequently, the investigators will evaluate progression of disease in children with early stages of subclinical rheumatic heart disease. The investigators will perform a population-based observational survey for rheumatic heart disease using portable echocardiography among schoolchildren aged 5 to 16 years from randomly selected public and private schools. Rheumatic heart disease will be documented both according to the modified World Health Organization definition and the echocardiographic criteria suggested by the World Heart Federation.

The hemodynamic parameters of 31 pregnant women with rheumatic valve disease, undergoing restorative dentistry under local anesthesia with 2% solution of lidocaine, divided in two groups, with (Group LE) and without 1:100,000 epinephrine solution (Group LNE), were studied by 24-hour ambulatory electrocardiographic monitoring, intermittent blood pressure monitoring and continuous cardiotocography, during three standard time periods. A significant decrease in the values of maternal heart rate was seen during the procedure, in comparison with the other two time periods in the two groups, as well as, the occurrence of cardiac arrhythmia in 9 (29.1%) patients, being 7 (41.8%) of them in the group receiving epinephrine anesthesia. We conclude the use of 2% lidocaine in association with epinephrine proved safe during dental procedure in pregnant women with rheumatic valve disease.
