A 55-year-old man was admitted with anterior chest pain. He had received aorto-renal bypass for left renal artery stenosis at the age of 24. His coronary angiography with ergotamine malate provocation showed 99% stenosis in the left anterior descending artery and circumflex artery and abdominal aortography revealed an aneurysm with a diameter of 4cm at the proximal site of the graft anastomosis. The patient was surgically treated with aneurysmectomy and PTFE grafting (7mm) between abdominal aorta and the already-implanted graft to the left renal artery. His postoperative course was uneventful and no major complication such as renal failure were observed. Anastomotic aneurysm is a fairly common complication associated with arterial reconstruction which is most common in the common femoral artery. This is the first reported case of anastomotic aneurysm complicated by aorto-renal bypass.

A 54-year-old man consulted our hospital because of nocturnal and mild exertional chest pain. Echocardiography demonstrated a mobile mass in the right atrium. There were no abnormal findings on the coronary angiogram. Because of the large size of the mass, surgical removal was carried out and a yellowish, globular tumor, sized 20×15×13mm, attached to the anterior tricuspid leaflet with a short stalk was excised. Postoperative recovery was uneventful. The patient was discharged from the hospital with no symptoms. The diagnosis of papillary fibroelastoma (PFE) was confirmed on histologic examination. PFE is a well-known tumor that usually arises on the heart valves. Although, historically, this tumor has incidentally been discovered at necropsy, clinical case reports have recently increased. However, the vast majority of clinically reported PFEs were the cases of the left side of the heart, for which the operative indication is quite definite because of serious complications such as cerebral or myocardial infarction caused by this tumor, irrespective of size. On the contrary, only a small number (17 cases) of the right heart PFEs have been reported in the literature and its operative indications are unclear. Review with regard to the operative indications for the right heart PFEs was made based on the total of 18 cases including our patient.
