Abstract
OBJECTIVE: To analyze late clinical evolution after surgical treatment of children, with reparative and reconstructive techniques without annular support.
METHODS: We evaluated 21 patients operated upon between 1975 and 1998. Age 4.67+/-3.44 years; 47.6% girls; mitral insufficiency 57.1% (12 cases), stenosis 28.6% (6 cases), and double lesion 14.3% (3 cases). The perfusion 43.10+/-9.50 min, and ischemia time were 29.40+/-10.50 min. The average clinical follow-up in mitral insufficiency was 41.52+/-53.61 months. In the stenosis group (4 patients) was 46.39+/-32.02 months, and in the double lesion group (3 patients), 39.41+/-37.5 months. The echocardiographic follow-up was in mitral insufficiency 37.17+/-39.51 months, stenosis 42.61+/-30.59 months, and in the double lesion 39.41+/-37.51 months.
RESULTS: Operative mortality was 9.5% (2 cases). No late deaths occurred. In the group with mitral insufficiency, 10 (83.3%) patients were asymptomatic (p=0.04). The majority with mild reflux (p=0.002). In the follow-up of the stenosis group, all were in functional class I (NYHA); and the mean transvalve gradient varied between 8 and 12 mmHg, average of 10.7 mmHg. In the double lesion group, 1 patient was reoperated at 43 months. No endocarditis or thromboembolism were reported.
CONCLUSION: Mitral stenosis repair has worse late results, related to the valve abnormalities and associated lesions. The correction of mitral insufficiency without annular support showed good long-term results.
