title: [Acute coronary syndrome caused by giant right coronary artery aneurysm; report of a case].
abstract: A 52-year-old man suffered from sudden chest pain. After urgent hospitalization, electrocardiogram showed complete atrioventricular (A-V) block. Computed tomography and coronary angiography showed a giant right coronary artery aneusysm. The patient was reffered to our hospital and elective operation was scheduled. The patient was re-attacked by chest pain and A-V block. Emergent coronary angiography showed mural thrombus in the right coronary artery aneurysm, which apparently caused the acute coronary syndrome. Under extracorporeal circulation, ligation of coronary artery aneurysm and coronary artery bypass using radial artery graft was performed. The postoperative course was uneventful. The histological findings revealed atherosclerotic coronary aneurysm.
