In this paper we analyse the mortality results in the valve reoperation. We compare the results of the conservative procedures and valve replacement, and relating this results to the number of previous operations. Two hundred and ninety-six patients were included in this paper, aged five to 72 years. Two hundred and eigth patients were submitted to mitral reoperations, 23 (7.8%) mitral recomissurotomy, two (0,7%) third comissurotomy, 26 (8.8%) first mitral valve replacement, 127 (42.9%) second mitral valve replacement, 26 (8.8%) third mitral valve replacement, three (1%) fourth mitral valve replacement. Aortic reoperations were performed in 67 patients, five (1.7%) first aortic replacement, 48 (16.2%) second aortic replacement, 11 (3.7) third aortic replacement and three (1%), fourth. Nineteen (6.4%) patients were submitted to mitro-aortic rereplacement, one (0.3%) to tricuspid rereplacement and one 0.3%) to mitrotricuspid rereplacement. The Hospital mortality was 0% (0/26), in mitral recomissurotomies, 15,4% (4/26) in first mitral replacement and no mortality in fourth and fifth mitral valve replacement. Relating to the aortic patients the Hospital mortality was 40% (2/5) in the first replacement, 14.6% (7/48) in the second replacement, no mortality (0/11) in the third replacement and 100% (3/3) in the fourth replacement. Relating to the mitro-aortic patients the statistical analysis showed no relation between mortality and mumber of previous operation.
