Reconstructive surgery of the mitral valve has been an alternative to mitral valve replacement in patients with mitral regurgitation. In order to evaluate the early results of mitral valve reconstruction, 38 consecutive cases were analyzed.Between January 1985 and May 1993, 38 patients with mitral valve incompetence were treated with a system of reconstructive techniques. Nineteen (52%) of the patients were in NYHA functional class II and seventeen (45%) in class III or IV preoperatively. The cause of the mitral disease was degenerative in 25 (66%), rheumatic in 6 (15%) and ischaemic in 5 (13%) patients. Isolated mitral valve repair was performed in 25 patients (66%); the remainder underwent associated procedures that included a myocardial revascularization in 9 patients (23.6%). Thirty-eight patients (100%) underwent a ring annuloplasty. Resection of the posterior leaflet was performed in 24 patients (63%).There was one operative death (2.6%) and two late deaths (5.3%). Postoperatively, four patients sustained embolic events (incidence 10.5%). Six patients (15.8%) were precociously reoperated within the following month; two patients required valve replacement, one had mediastinitis and three other ones needed a pericardial drainage. Patients routinely received acenocoumarol anticoagulation for two months. Mean follow-up was 33 months (range 6 to 104) and one patient was lost to follow-up. Two years actuarial survival was 91.4%. There were no thromboembolic complications in the follow-up period. No patient was reoperated for valvular insufficiency beyond this time limit. One patient had late endocarditis and has been reoperated for mitral replacement (2.6%). After surgery, 34 survivors (89.5%) were in the NYHA functional class I or II.These results demonstrate that mitral valvuloplasty is associated with lower operative mortality rates. Preservation of the mitral valve mechanism raised the performance of the left ventricle after reconstructive surgery. The incidence of reoperation and thromboembolism was low. |
