[Echocardiographic diagnosis of 4 cases of tricuspid valve endocarditis].

Four tricuspid endocarditis cases are reported. Echocardiography found, four times, large vegetations on the tricuspid leaflets leading to the diagnosis. The degree of tricuspid insuffisancy was appreciated by the RV/LV ratio. Successive echos have permitted to survey the evolution and specially to establish a clear decrease of abnormal tricuspid echoes succeeding to pulmonary embolisms. In the four cases, surgery confirmed the diagnosis.
