Robotic mitral valve repair: quadrangular resection and bidirectional sliding valvuloplasty.

Systolic anterior motion remains a recognized complication of mitral valve repair, for which sliding valvuloplasty was originally developed as a preventive strategy. This technique is used in patients with a broad area of posterior leaflet prolapse and excessive leaflet height. We demonstrate our modification of the classic sliding plasty, including further adaptations to enable its reliable and efficient application via a minimally invasive robotic approach.
