title: Right ventricular myxoma mimicking recurrent pulmonary embolism after primary ligament reconstruction.
abstract: Recurrent pulmonary emboli may be due to numerous causes and deep vein thrombosis are not an unusual source of pulmonary emboli following surgery. In this case report, the diagnostic approach and implications of a right ventricular myxoma as a rare source in a young patient is described. A 27-year old healthy woman presented scintigraphically proven recurrent pulmonary emboli after primary ligament reconstruction. Following a long period of diagnostic work-up for thromboembolism after surgery, a transthoracic and transoesophageal echocardiography was performed to document a right ventricular myxoma. Both transthoracic and transoesophageal echocardiography are powerful diagnostic means in a cardiac work-up and were used in this patient for the documentation of a right ventricular myxoma mimicking deep vein thromboembolism after surgery. As consequence of this case report we recommend to investigate patients with recurrent pulmonary embolism and no detectable venous thrombosis by echocardiography and a need for cardiac catheterization is restricted to patients with possible coexisting coronary artery disease. Furthermore, this case report demonstrates a myxoma in the right ventricle occurring only in 3-4% of all myxomas.
