Case Reports[Floating right atrial thrombus as the cause of recurring pulmonary embolisms].
After an attack of pleuropneumonia a 25-year-old woman developed persistent dyspnoea due to pulmonary emboli, as demonstrated by scintigraphy. There was no clinical or phlebographic evidence of the peripheral venous system as the source. Two-dimensional echocardiography demonstrated a floating spherical tumour in the right atrium, attached to the interatrial septum and prolapsing into the right ventricle during ventricular diastole. ⋯ It proved to be myxoma-like, 3 x 3 cm in diameter. Histologically it was a thrombus without evidence of myxoma. No further thromboemboli occurred under phenprocoumon anticoagulation.
