Mitral valve incompetence in elderly patients raises the problem of whether to replace or to repair the mitral valve. The purpose of this study is to review our experience with mitral valve repair in patients70 years old.Between 1986 and 1991, 79 consecutive patients70 years old underwent mitral valve repair by Carpentier techniques. The most frequent cause was degenerative valve disease (65 of 79). Preoperative echocardiography showed that 6% of the patients had type I, 88% type II, and 5% type III mitral valve dysfunction. Anatomic lesions encountered at surgery confirmed the preoperative echocardiographic findings, with 88% of the patients with a leaflet prolapse either of the posterior leaflet (56%) or of both the anterior and posterior leaflets (32%). Multiple surgical procedures were required in each patient. Posterior leaflet resection was the most common technique used (76%). Prosthetic ring annuloplasty was used in 96% of patients. Associated procedures were performed in 21.5% of cases. Three patients died, for an operative mortality of 3.8%. One patient (1.3%) required reoperation for residual mitral insufficiency. Nonfatal complications related to the patients' preoperative condition were noted in more than half of the patients. Echocardiography obtained before discharge revealed absent or minimal mitral insufficiency in 91% of patients and mild mitral insufficiency (2+/4+) in 9%. Follow-up was available for 74 of 76 patients (97.3%) and ranged from 3 months to 6 years (mean, 22 months). Two patients (2.6%) were lost to follow-up. Sixty patients (89%) were in New York Heart Association functional class I or II. Seven patients died and one required reoperation. Actuarial analysis of the results showed overall survival at 5 years 81 +/- 11%; freedom from thromboembolism, hemorrhage, and reoperation 97 +/- 5%, 97 +/- 5%, and 98 +/- 4%, respectively. Color-coded echo Doppler studies obtained in 67 patients at the time of follow-up showed absent or minimal MI (91%) (n = 61), and mild MI in 9% (n = 6).These data suggest that mitral valve repair using Carpentier techniques should now be considered as the procedure of choice in patients of any age referred for mitral insufficiency. |
