Carpentier "sliding leaflet" technique for repair of the mitral valve: early results.
Reconstructive mitral valve operation is now the preferred technique for the surgical treatment of prolapse of the posterior leaflet due to degenerative disease. Systolic anterior motion of the mitral valve with left ventricular outflow tract obstruction has been observed after such repair, with an incidence ranging from 4.5% to 10%. In an attempt to reduce the incidence of this complication, Carpentier has devised a new technique: the sliding leaflet plasty of the posterior leaflet. We report on 48 patients who underwent this new procedure between July 1990 and July 1992. One patient died perioperatively (2.1%). All other patients were able to be discharged on the ninth postoperative day. All patients underwent M-mode, two-dimensional, and Doppler echocardiography before discharge. Forty-one patients (85%) had no evidence of postoperative regurgitation, whereas 7 patients (15%) showed mild mitral valve insufficiency. Left ventricular outflow tract obstruction due to systolic anterior motion of the mitral valve was never detected. We believe that this technique of mitral valve repair is safe and seems to be effective in achieving a decreased incidence of left ventricular outflow tract obstruction.
