[Acute Coronary Syndrome Caused by Papillary Fibroelastoma:Report of a Case].

ABSTRACT

A 72-year-old female had persistent severe chest pain while climbing stairs. She was diagnosed as having acute coronary syndrome, and underwent an emergency coronary angiography (CAG). The right coronary artery (RCA) ostium was sub-totally occluded. Echocardiography revealed a 10 mm mobile mass at the right coronary cusp of the aortic valve. To avoid total obustruction on two drug eluting stents were placed at the RCA ostium so as to have the proximal end protrude into the right Valsalva sinus. Thus, her hemodynamic condition was stabilized. The tumor was surgically resected and the stents were easily removed. Pathologically, the tumor was papillary fibroelastoma. Postoperative aortic regurgitation was minimal echocardiography, and CAG showed normal RCA.
