JUAN A. CRESTANELLO: Welcome to the Cardiovascular Surgery Series, where I review of the latest research in cardiovascular surgery from the Mayo Clinic in just 2 minutes. I am Dr. Juan Crestanello. I will discuss today, robotic versus minimally invasive mitral valve repair-- a 5-year comparison of surgical outcomes.

Minimally invasive mitral valve repair is commonly performed either robotically or non-robotically through a right mini thoracotomy. We review patients who underwent robotic mitral valve repair at our institution or mitral valve repair via a mini right thoracotomy between 2015 and 2020.

69 matched pairs were included in the study. Robotic and non-robotic mitral valve repair had similar operative characteristics, except the robotic had longer cross-clamp times. There was no difference in operative outcomes. And the operative mortality was 0. Hospital stay was shorter after robotic mitral valve repair.

After a median follow-up of 3.3 years, there was no mortality in either group, and there was no difference in freedom from mitral valve reoperations between robotic and non-robotic mitral valve repairs. By echocardiogram follow-up, excellent free of recurrence, moderate or severe mitral valve regurgitation was found at three years. We conclude that both short- and mid-term outcomes of robotic and non-robotic minimally invasive mitral valve repair are comparable. Thank you for listening to the Mayo Clinic Cardiovascular Surgery Series.
