We report a 66-year-old woman with circulatory collapse due to acute pulmonary thromboembolism, in whom a left nephrectomy for a renal tumor was scheduled. Following preoperative renal angiography. The patient suffered sudden shock resulting from pulmonary thromboembolism (PTE) following release of compression of the puncture site. The patient was transported to the ICU, and percutaneous cardiopulmonary support (PCPS) was instituted immediately for resuscitation. Hemodynamics were stabilized by PCPS and percutaneous thrombectomy was attempted. However, perforation by a catheter inverted to the extracardiac space occurred, which neccesitated emergency surgical hemostasis. PCPS was converted to cardiopulmonary bypass (CPB). The injured right ventricle and right atrial walls were repaired, and pulmonary thrombectomy was performed via the pulmonary trunk. CPB was easily terminated and her postoperative course was uneventful with anticoagulant therapy. Left nephrectomy was performed two months later. PTE recurred due to the interruption of anticoagulation for surgical treatment of a renal tumor. Percutaneous pulmonary thrombectomy and thrombolysis therapy were effective and a Greenfield filter was inserted into the inferior vena cava to prevent recurrence.

We report an 81-year-old woman with giant left atrial myxoma who had been admitted with congestive heart failure. Diagnosis was established by echocardiography and a moderate degree of tricuspid valve regurgitation was also found. The tumor was extensively attached to the atrial septum, and was excised completely including endocardium. She had concomitant tricuspid annuloplasty. Atrial fibrillation occurred on postoperative day 10, but conversion to a sinus rhythm was seen on postoperative day 19. She was discharged in good condition on postoperative day 36. Even in a patient over 80 years old with congestive heart failure, aggressive surgical treatment of left atrial myxoma should be performed.
