A man in his 50s was admitted to the hospital with acute chest pain and dyspnea. On examination, his systolic blood pressure was 82 mm Hg, and heart rate was 125 beats per minute. Coronary computed tomography angiography (, A) and transesophageal echocardiogram () revealed a tortuous coronary artery fistula (CAF) with a giant cauliflowerlike aneurysm originating from the dilated left main trunk and draining into the main pulmonary artery. Considering the presence of hemopericardium (, A), spontaneous ruptured aneurysm secondary to CAF was suspected as the cause of cardiac tamponade. This diagnosis was confirmed by the findings of emergency surgery (, B; ). Surgical repair was successfully performed with aneurysm excision, fistula closure, and coronary artery bypass grafting (). The postoperative course was uneventful. Cardiac tamponade attributable to ruptured aneurysm of a CAF is exceptionally rare but life-threatening; such a condition requires prompt diagnosis and urgent surgery.,
