A Technique for Annular Plication to Facilitate Sliding Plasty After Extensive Mitral Valve Posterior Leaflet Resection

The sliding leaflet technique has been used in mitral valve repair in conjunction with posterior leaflet quadrangular resection to avoid left ventricular outflow tract obstruction secondary to systolic anterior motion of the anterior leaflet of the mitral valve. On occasion, despite the use of the sliding leaflet technique, reattachment of the edges of the posterior leaflet after extensive resection can be challenging because of excessive tension. My colleagues and I present our technique to ensure reattachment of the posterior leaflet without tension after extensive resection.
