Minimally invasive mitral valve repair for commissural prolapse: Safety, success, and long-term efficacy.

ABSTRACT:

Objectives

Commissural prolapse (CP) is a rare and complex mitral valve pathology which is complicated in preoperative diagnosis and repair. This study evaluated the safety, success, and long-term efficacy of minimally invasive mitral valve repair (MIMVR) for CP compared to posterior leaflet prolapse (PMLp).

Methods

Between 2001 and 2022, 34 patients with CP and 590 with PMLp underwent MIMVR at our center. Operative, perioperative, and long-term follow-up data were retrospectively collected. Surgical success was defined as freedom from conversion to valve replacement, sternotomy, and residual mitral regurgitation (MR) > grade I. Long-term efficacy included MR recurrence, reoperation, and survival.

Results

Median age was similar (CP: 64.0 years [53.2; 69.8] vs PMLp: 62
