Abstract
A 63-year-old woman with annuloaortic ectasia and severe aortic regurgitation was referred to our hospital. Preoperative coronary angiography revealed 50% stenosis of the orifice of the left main trunk. She underwent aortic root replacement, but we were unable to insert a 12-gauge cannula into the orifice of the left coronary artery because of cardioplegia. Therefore, we decided to perform patch plasty of the left main trunk by a saphenous vein patch. Her postoperative course was uneventful, and postoperative computed tomography (CT) showed good expansion of the left main trunk without any evidence of aneurysm formation.
