Robotic annular plication for repair of posterior mitral leaflet prolapse.

Annular plication is a fundamental technique in mitral valve repair, forming a core component of classic quadrangular resection by enabling tension-free re-approximation of the cut leaflet edges. While smaller resections are more commonly performed in the current era, annular plication remains essential in selected cases. We describe a modification of the originally described technique that allows efficient, accurate application while preserving its underlying surgical principles.
