Durable Robotic Mitral Repair of Degenerative Primary Regurgitation With Long-Term Follow-Up.

ABSTRACT:

Background

Variation in degenerative mitral morphology may contribute to suboptimal repair rates. This study evaluates outcomes of a standardized mitral repair technique.

Methods

An institutional clinical registry was used to identify 1036 consecutive patients undergoing robotic mitral surgery between 2005 and 2020: 87% (n = 902) had degenerative disease. Calcification, failed transcatheter repair, and endocarditis were excluded, leaving 582 (68%) patients with isolated posterior leaflet and 268 (32%) with anterior or bileaflet prolapse. Standardized repair comprised triangular resection and true-sized flexible band in posterior leaflet prolapse. Freedom from greater than 2+ moderate mitral regurgitation stratified by prolapse location was assessed using competing risk analy
