Introduction
Coronary ostial aneurysm (COA) is one of the fatal complications after aortic root replacement (ARR) 1, 2 and the higher incidence in patients with Marfan syndrome (MFS) has been reported.3 Surgical procedures to reconstruct coronary ostium is still an important issue to secure coronary perfusion and avoid COA recurrent. Herein, we report a case of short segment coronary artery bypass grafting (CABG) using radial artery (RA) to repair bilateral COA after ARR in a 48-year-old patient with MFS.
