We report a case of transcatheter aortic valve implantation in a 79-year-old woman with a coronary anomaly who underwent surgical aortic valve replacement with a 23-mm Abbott Trifecta bioprosthesis. The procedure was performed in response to severe aortic stenosis caused by a bicuspid aortic valve. Computed tomography showed an anomalous origin of the right coronary artery from the left coronary sinus, with an interarterial course. Although the virtual transcatheter valve to coronary ostium distance-right coronary artery was short, the right coronary artery ostium was just behind the stent post. The externally mounted leaflet was unable to reach the coronary orifice beyond the stent post. This case highlights a successful transcatheter aortic valve implantation for stented bioprostheses with externally mounted leaflets when the virtual transcatheter valve to coronary ostium distance is shortened by a coronary anomaly.
