A Successful Case of Re-coronary Artery Bypass Grafting for the Graft Stenosis of Aortic Valve Translocation via the Left Thoractomy Approach with a Radial Artery Conduit / 日本心臓血管外科学会雑誌

ABSTRACT

A 79-year-old man underwent aortic valve replacement by xenografts for active infective endocarditis with aortic regurgitation. Two months later, he developed congestive heart failure and uncontrolled infective endocarditis. The second operation was performed 3 months later, with an aortic valve translocation procedure because of aortic regurgitation due to aortic root abscess and prosthetic valve endocarditis. Six months after the second operation, the saphenous vein graft (SVG) to the left coronary artery (LAD) revealed a severe stenotic lesion at the proximal site. The stenotic vein graft fed almost the entire left coronary circulation. The third operation was performed via left thoracotomy, under hypothermic circulatory arrest with cardiopulmonary bypass. A new radial artery (RA) graft was anastomosed between the descending thoracic artery and the old SVG for LAD. The patient recovered without any major complications and postoperative angiography showed that the new RA graft was patent.
