We report the successful repair of left main coronary artery obstruction with aortitis syndrome. She was a 39-year-old woman and was admitted to Saiseikai Kumamoto Hospital because of angina pectoris. Her bilateral radial artery pulsation was not palpable. Total occlusion of the left main coronary artery (LMT) and bilateral subclavian artery was detected by angiography. Patch enlargement of the LMT was performed using a Distaflo (Impra Carbon PTFE) graft. Postoperative coronary angiography showed an adequate LMT diameter and sufficient blood flow.

A 68-year-old woman was referred to our hospital with arrhythmia and cardiomegaly. She lost consciousness in the waiting room. After urgent hospitalization, cardiac ultrasonography showed cardiac tamponade, and urgent pericardial drainage was performed. A ruptured coronary aneurysm with a fistulous communication was diagnosed by CT scan and coronary angiography. Under extracorporeal circulation, ligation of the unusual coronary vessels and resection of the aneurysm were performed. The postoperative course was uneventful and she was discharged on the 25th postoperative day. No ischemic signs were observed on treadmill test at one year after surgery. Most congenital coronary aneurysms are asymptomatic; however, once rupture occurs, it is important to diagnose this condition rapidly and treat surgically.
