Objective: Conservative procedures on the valve mitral have advantages over its replacement. We evaluated the mid term results in patients with rheumatic mitral disease regarding clinical and echocardiography variables. Material and Methods: Fifty six patients with rheumatic etiology were submitted to mitral valve repair. Forty six patients were female (82.1%) and ten male (17.9%). The average age was 34.70 years (standard deviation 13.88 years). Average time of follow-up was 23.84 months (standard deviation 9.23 years). Twenty five patients (44.6%) were in functional class III or IV and eleven patients with atrial fibrillation (19.6%) before surgery. The procedures were commissurotomy, commissurotomy with papillaromyotomy in 11 patient (19.6%), commissurotomy with malleable annuloplasty bovine pericardium prosthesis in 27 patients (48.2%) and malleable annuloplasty bovine pericardium prosthesis in 18 patients (32.1%). Results: There was one death (30 days) in this series (1.7%). One patient presented transitory vascular accident in the operative period with total recovery. Improvement ocurred with regard to the final diastolic volume of the left ventricule from 52.0 ± 12.4 mm to 48.8 ± 9.9 (p = 0.001), left atrium size from 53.0 ± 8.0 mm to 47.8 ± 7.6 mm (p < 0.0001). Functional class improved significantly (p = 0.0001), with just one patient in class III (1.8%). It happened two reoperations with 28.5 months and 2.93 months of follow-up, 96.43% were free reoperation in the follow-up period. Conclusion: We conclude that mitral valve repair over the mid term provides good results with improvement of echocardiography and clinical parameters.
