Surgery for mild tricuspid regurgitation during mitral valve repair

Annuloplasty for the Treatment of Not-Severe Tricuspid Regurgitation in Patients Undergoing Surgery for Mitral Valve Disease: a Prospective, Spontaneous, Multicentre, Randomized Study

Not applicable Interventional Ospedale San Raffaele · NCT02996552

This study is testing if adding a specific heart surgery for mild tricuspid regurgitation can help patients who are already having mitral valve surgery to avoid future heart problems.

What this trial studies

This clinical trial investigates the effectiveness of tricuspid annuloplasty in patients with mild tricuspid regurgitation (TR) undergoing mitral valve surgery. It aims to determine whether performing this procedure in patients with a dilated tricuspid annulus can prevent disease progression. The study is a multicenter, single-blind, parallel group randomized controlled trial, where participants will be randomly assigned to either receive tricuspid annuloplasty or undergo mitral valve repair only. The trial will enroll patients with TR ≤ 2+ and annular dilation to assess the potential benefits of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old scheduled for mitral valve surgery with mild tricuspid regurgitation and a dilated tricuspid annulus.

Not a fit: Patients with severe tricuspid regurgitation (TR ≥ 3) or organic disease of the tricuspid valve may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence for a surgical approach that prevents the progression of tricuspid disease in patients undergoing mitral valve surgery.

How similar studies have performed: While some observational studies suggest potential benefits, this approach remains controversial and lacks robust evidence from randomized trials.
