Prolapsing right atrial myxoma.
Echocardiography was of great value in establishing the correct diagnosis in a patient with symptoms of congestive heart failure due to a prolapsing right atrial myxoma. The movement of the tumor into the right ventricle through the atrioventricular orifice during diastole was identified by the echocardiogram and confirmed by angiography and direct observations during surgery. The indicator dilution curve also showed abnormal hemodynamic features simulating tricuspid incompetence, in relation to the movement of the tumor.
