A Y-incision to enlarge the aortic root for aortic valve stenosis with anomalous aortic origin of the right coronary artery

Abstract

Abstract Background Anomalous aortic origin of the coronary artery (AAOCA) is a rare congenital heart disease. Therefore, optimal indications for surgery in patients with severe aortic valve stenosis (AS) complicated by AAOCA remain uncertain. Case presentation We report the case of a 57-year-old male patient who underwent aortic valve replacement (AVR) and aortic root enlargement using a Y-incision procedure for severe AS with an anomalous aortic origin of the right coronary artery (AAORCA). Since preoperative single-photon emission computed tomography revealed no ischaemic lesions, an aortic root enlargement with a Y-incision was performed to prevent the potential compression of the prosthetic valve on the AAOCA and prosthesis-patient mismatch. Conclusions Preoperative evaluation of the coronary anatomy and myocardial ischaemia using advanced imaging modalities and aortic root enlargement with the Y-incision procedure is an effective strategy for preventing ischaemic complications in cases of severe AS with AAORCA.
