The edges of that leaflet are reconnected. E. An annuloplasty ring is placed. Systolic anterior motion, or SAM, is a complication that may occur with mitral valve repair procedures. The redundant posterior leaflet tissue pushes the anterior leaflet into the left ventricular outflow tract, causing obstruction. Whereas this complication was once fairly common, the development of the sliding leaflet technique by Carpentier has helped significantly to reduce its rate of occurrence.
Calcification often extends through the wall of the heart.
An annuloplasty ring supports the repair. Whereas this procedure is fairly uncommon, many times a surgeon will elect to do a valve replacement rather than attempt the repair. Inc. All Rights Reserved.
