Robotic mitral valve repair for all categories of leaflet prolapse: Improving patient appeal and advancing standard of care

Abstract

OBJECTIVE: To characterize the early outcomes of robotic mitral valve (MV) repair using standard open techniques. PATIENTS AND METHODS: We prospectively studied 100 patients with severe mitral regurgitation due to leaflet prolapse who underwent robot-assisted MV repair using conventional open-repair techniques between January 1, 2008, and December 31, 2009, at Mayo Clinic, Rochester, MN. RESULTS: The mean age of the patients was 53.9 years; 77 patients (77%) were male. Fifty-nine patients (59%) had posterior leaflet prolapse, 38 (38%) had bileaflet disease, and 3 (3%) had isolated anterior leaflet prolapse. Median cross-clamp and bypass times decreased significantly during the course of the study (P
