Abstract
From May 1985 to May 1992, 169 patients underwent surgery for mitral valve repair. In 87% of these patients, the valve reconstruction involved the mitral annulus. At the beginning, in an effort to preserve systolic movement of the annulus and avoid the implant of prosthetic materials inside the heart, we mainly used simple suture annuloplasty in 66 patients. When we reoperated upon three patients only a few months after reconstruction of the mitral valve for a dehiscence of the suture annuloplasty, we decided to perform ring annuloplasty with the Carpentier ring in 23 patients. Though we have not seen any problems with the Carpentier ring in our series, we performed a suture annuloplasty reinforced with a strip of autologous pericardium to eliminate all prosthetic material. Since introducing this technique in 1989, we have used this annuloplasty in 58 patients. We have not observed any dehiscence of the suture or other complications related to this procedure. Three patients with a pericardial annuloplasty underwent reoperation for other reasons; the autologous pericardium was perfectly attached to the annulus, covered by a smooth layer of fibrous tissue without calcification. After this encouraging initial experience, we believe that long-term follow-up is necessary to confirm that autologous pericardium is an effective method of mitral annulus repair.
