550 Robotic Totally Endoscopic Mitral Valve Surgeries Within a Comprehensive Robotic Cardiac Program

Area of Science:

• Minimally Invasive Cardiac Surgery
• Robotic Surgery
• Valvular Heart Disease

Background:

• Initiation of a comprehensive multispectrum robotic cardiac surgery program in 2013.
• Emphasis on the totally endoscopic approach for cardiac procedures.
• Review of mitral valve (MV) operations within this program's context.

Purpose of the Study:

• To evaluate the outcomes of robotic totally endoscopic mitral valve (MV) procedures.
• To assess the feasibility and success of MV surgery using a minimally invasive robotic approach.
• To analyze patient data collected according to Mitral Valve Academic Research Consortium definitions.

Main Methods:

• Retrospective review of 1714 robotic endoscopic cardiac surgeries (September 2013 - February 2024).
• Analysis of outcomes for 550 consecutive patients undergoing robotic totally endoscopic MV operations.
• Data collection adhering to Mitral Valve Academic Research Consortium standards.

Main Results:

• High MV repair rate (98%) in degenerative mitral regurgitation (MR).
• Excellent 30-day surgical success (95.9%) and procedural success (93.0%) for MV repair.
• Low 30-day mortality (0.6 observed/expected) and short hospital stay (2.8 days).
• Five-year freedom from reoperation for recurrent MR was 95.7%.

Conclusions:

• Robotic endoscopic mitral valve surgery is a feasible and effective option.
• Successful integration within a comprehensive robotic cardiac surgery program.
• Demonstrates favorable short-term and long-term outcomes for MV repair and replacement.
