Does robotic mitral valve repair using the da Vinci system provide safe and effective outcomes in patients requiring mitral valve surgery?
Robotic mitral valve repair using the da Vinci system is safe and yields excellent early results, with a 93.5% rate of no residual mitral regurgitation.
Supports safety in experienced centers; leaves open comparative effectiveness versus conventional approaches in randomized trials.
BACKGROUND: Robotic mitral valve repair using the da Vinci telemanupilation system has become the standard of care at many centres worldwide. We perform the first robotic MV repair in the United States in the year 2000. This article reviews our 6 year experience and current technique of robotic MV repair as well as future trends in the field. METHODS: Retrospective review of our initial 200 robotic MV repairs. Patient demographics, operative times, type of repairs, morbidities, mortality, success of the repair including need for reoperations were reviewed. RESULTS: The average age was 57 +/- 0.9 years. Average time for CPB was 156 minutes and for cross clamp 119 minutes. There was one operative death (0.5%) with no device related complications. Postoperative TEE demonstrated no MR in 187 (93.5%) patients, trace MR in 6 (3%) patients, moderate MR in 5 (2.5%) patients, and SAM in 2 (1%) patients. Five (2.5%) patients required reoperation for failed repairs. CONCLUSIONS: Robotic MV repair operations are safe with excellent early results. Follow-up studies are needed to determine repair longevity. We must continue to improve the current technology in order to develop the next generation of tools that will facilitate robotic MV repairs.

Rodríguez et al. (2006) conducted an observational in Mitral valve disease (n=200). Robotic mitral valve repair was evaluated on Operative mortality, morbidities, and success of repair. Robotic mitral valve repair resulted in a 0.5% operative mortality rate and 93.5% of patients having no mitral regurgitation on postoperative transesophageal echocardiography.
