[Coronary-pulmonary Artery Fistula Manifested by Cardiac Tamponade;Report of a Case].

: Coronary-pulmonary artery fistula( CPAF) is a relatively rare congenital malformation. We successfully treated a patient who presented with cardiac tamponade due to ruptured CPAF. A 58-year-old woman was admitted to our hospital due to consciousness disorder. Enhanced computed tomography revealed hemopericardium, and she was diagnosed with cardiac tamponade due to a ruptured coronary artery aneurysm with fistula arising from the right coronary and entering the main pulmonary artery. Therefore, emergency operation was performed. Under cardiopulmonary bypass, the aneurysm was opened and the ostium of the fistula was closed with pledgetted mattress sutures. After ligating the tortuous CPAF, the aneurysmal wall was sutured. Postoperative course was uneventful, and she was discharged on postoperative day 16.
