Tricuspid valve thromboembolus with recurrent pulmonary embolism--a case report

The authors describe a fifty-one-year-old man with multiple pulmonary emboli in whom two-dimensional echocardiography clearly showed a large mobile thrombus transiently entrapped in the chordal apparatus of the tricuspid valve, a location rarely noted except in autopsy specimens. Subsequent lung scan and echocardiograms documented clinically silent nonfatal embolization of this large thrombus to the lungs. Whereas most patients with this form of thromboembolic disease come to either surgery or autopsy, this case demonstrates how the combination of echocardiography and lung scanning can be used to differentiate the etiology of some right-heart masses.
