Summary
Experienced surgical teams can advance robotic mitral valve repair techniques. Increased complexity in subvalvular procedures demonstrates enhanced proficiency in totally endoscopic intracardiac robotic surgery.
Area of Science:
- Cardiac Surgery
- Robotic Surgery
- Mitral Valve Repair
Background:
- Totally endoscopic intracardiac robotic surgery is typically limited to uncomplicated mitral valve procedures.
- An experienced team developed an aggressive approach for complex mitral valve pathologies.
Purpose of the Study:
- To report advancements in complex subvalvular robotic cardiac surgery techniques.
- To correlate procedural complexity with team experience and capabilities.
Main Methods:
- Review of 1287 robotic mitral procedures (July 2011-May 2022) by a 2-surgeon team.
- Natural language processing of operative reports to identify subvalvular repair techniques.
- Comparison of early (pre-2018) versus late (2018 onwards) robotic surgical experience.
Main Results:
- 1024 mitral valve repairs were performed; 30-day mortality was 0.6%.
- Significant increase in advanced subvalvular techniques from early to late experience (52.3% vs. 74.2%, P < .001).
- Complex techniques included papillary muscle repositioning, chordae division, and ventricular reconstruction.
Conclusions:
- An experienced 2-surgeon team can progressively perform more complex robotic subvalvular repair.
- The application of advanced subvalvular techniques indicates team proficiency and enhanced capabilities in robotic cardiac surgery.
