Cardiac tamponade due to a rupture of the coronary arteriovenous aneurysm--a case report.
We experienced an unusual case of cardiac tamponde caused by a rupture of the coronary arteriovenous aneurysm in a 54-year-old woman. The patient was suffered from sudden chest pain and syncope, and was initially managed by pericardiocentesis following an echocardiogram which revealed a massive pericardial effusion with signs of cardiac tamponade. She was referred to our hospital under the impression of aortic dissection with cardiac tamponade. She underwent an emergency operation and was found to have a 2 x 2 cm sized bleeding cystic mass protruding from the proximal anterior descending coronary artery. The aneurysm was excised and the openings connected with the coronary artery and right ventricular outflow tract were closed with sutures from the inside of aneurysm. Subsequent coronary arteriography supported the diagnosis.
