Robotic folding plasty for repair of posterior mitral leaflet prolapse.

Folding plasty is a valuable technique for reducing excessive posterior leaflet height and mitigating the risk of systolic anterior motion. It offers a simpler alternative to the classic quadrangular resection with sliding plasty and has demonstrated comparable long-term durability when applied in appropriate settings. We have adopted this technique widely and employ it frequently in both open and robotic mitral valve repair.
