Comparing drug therapies to improve heart function after mitral valve repair in children

A Prospective Controlled Study for the Treatment Effect of Different Intervention Strategies for Pediatric Mitral Regurgitation--A Multicenter Prospective Cohort Study of Innovative Drug Therapy in Improving Left Ventricular Function After Mitral Repair

Observational China National Center for Cardiovascular Diseases · NCT06039592

This study is testing if a new combination of heart medications can help children feel better and improve heart function after they have surgery to fix their mitral valve.

What this trial studies

This observational study aims to evaluate the safety and effectiveness of a modified drug therapy compared to traditional drug therapy in pediatric patients who have undergone mitral valve repair. Participants will be assigned to either the Modified Drug Therapy Group, which includes a combination of ACE inhibitors, beta-blockers, diuretics, potassium supplements, and spironolactone, or the Traditional Drug Therapy Group, which consists of diuretics and potassium supplements. The study will monitor improvements in left ventricular and mitral valve function over a 6-month period, alongside assessing any adverse drug reactions. Echocardiography and other clinical assessments will be conducted to gather comprehensive data on patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric patients under 14 years old who have recently undergone mitral valve repair.

Not a fit: Patients with severe heart failure, pulmonary hypertension, or significant organ failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved heart function and better overall health outcomes for pediatric patients after mitral valve repair.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in improving outcomes for patients with congenital heart disease.
