Comparing mitral valve repair strategies 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 Strategies for Mitral Valve Repair

China National Center for Cardiovascular Diseases · NCT06037447

This study is testing two different ways to fix a heart valve in children under 14 with mild to moderate valve problems to see which method works better and is safer.

What this trial studies

This observational study aims to evaluate the safety and effectiveness of a three-step standardized repair-oriented strategy versus annuloplasty alone in pediatric patients with mild to moderate mitral valve regurgitation. The study will assess improvements in left ventricular and mitral valve function while monitoring for surgical complications. Participants will be assigned to one of the two treatment groups based on their eligibility criteria, which includes children under 14 years old who have not previously undergone mitral valve surgery.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients under 14 years old with moderate to severe mitral regurgitation who have not had prior mitral valve surgery.

Not a fit: Patients with other significant cardiac malformations or conditions that contraindicate mitral valve surgery will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and heart function in children with mitral valve issues.

How similar studies have performed: While this approach is innovative, similar studies have shown varying degrees of success in improving surgical outcomes in pediatric cardiac patients.
