ABSTRACT: Case 1: A 77-year-old woman had effort angina pectoris. Coronary angiography (CAG) revealed a coronary artery aneurysm on the left descending artery. Coronary artery bypass grafting (CABG) and patch angioplasty for the aneurysm were performed. Case 2 : A 69-year-old woman had effort dyspnea CAG showed dilation of the left main trunk and beaded aneurysms (maximum 6 cm in diameter) behind the ascending aorta with a fistula to the right atrium. We closed the fistula and performed CABG to the circumflex branch. Case 3 : A 78-year-old woman had had general fatigue for 2 weeks. Previous CAG had revealed coronary artery aneurysms and current chest computered tomography revealed pericardial effusion. She was, therefore, diagnosed with the rupture of the coronary artery aneurysm. We closed the coronary artery aneurysm and performed CABG. Case 4: A 55-year-old man had been diagnosed with acute myocardial infarction and had undergone percutaneous coronary intervention 3 years before. CAG revealed a coronary artery aneurysm on the right coronary artery. We resected the aneurysm and interposed with saphenous vein graft. Although coronary artery aneurysm often has no symptoms, in the cases of angina, myocardial infarction, rupture or large aneurysm more than 3 times larger than the normal diameter, surgical repair should be considered.Kyobu geka.

Article: [Preservation of aortic root with severe destruction in Stanford type A acute aortic dissection].[show abstract] [hide abstract]
ABSTRACT: From November 1999 to December 2008, 197 patients with Stanford type A acute aortic dissection underwent the surgical treatment on an emergency basis. In 19 cases, we preserved the severely destroyed aortic root using gelatin-resorcin-formalin (GRF) glue avoiding aortic root replacement. We examined the indication and limitation of repair of the destroyed aortic root. The 19 patients were classified into 3 groups (A, B and C). Group A consisted of 7 patients who had no aortic regurgitation (AR). Group B consisted of 6 patients who had moderate to severe AR. Group C consisted of 6 patients who had coronary involvement. We preserved the broken aortic root in group A and group B. But it seemed to be rather difficult to repair the destroyed aortic root in some cases of group C.Kyobu geka.
