The authors present the results of the utilization of Bioval bovine pericardium bioprosthesis in 73 patients operated upon in Bauru, SP. from September 1982 to December 1987. Thirty nine patients had mitral disease, 25 aortic, 6 both mitral and aortic, 2 had aortic and coronary disease and 1, mitral and coronary disease. The hospital mortality was 5.4% and none of them was valve related. There were only one patient with atrial thrombus and 1 patient with mild mitral calcification, which didn't require re-operation. Actuarial survival in 60 months follow-up was 82% for total, 88% for mitral and 78% for aortic patients. Late death was 2.7 events/100 patients/year. In conclusion, this prosthesis had a very good performance in this group of patients.
