title: [Thrombosis of mechanical heart valve prosthesis. Predisposing factors and results of surgical treatment].
abstract: Heart valve thrombosis is a serious complication. From February, 1995 to January, 1996, 19 patients were studied to identify predisposing factors and results of surgical management. Mean age was 47.3 years. Thirteen patients (73.6%) had an irregular surveillance of anticoagulation therapy. Fifteen patients showed low anticoagulation effect during their evolution. Sixteen patients were in functional class III and 80% (15 patients) showed imaging of thrombus in the echocardiographic study. All patients presented thrombus on both sides of the prothesis. There were no deaths, and 15 patients returned to functional class I. It was concluded that the main predisposing factor in this series of patients was deficient anticoagulation therapy, and surgical results are comparable to those other authors.
