Abstract:
Triangular resection is an effective repair technique for isolated segmental posterior leaflet prolapse in mitral valves at low risk for systolic anterior motion. It is applicable in the majority of such cases, is low risk, and has excellent long-term durability. Its simplicity and efficacy make it an essential part of every mitral surgeon's armamentarium. Herein we present our robotic approach to triangular resection, highlighting subtle adaptations from the open technique.
