INTRODUCTIONNeoaortic root dilatation and valve regurgitation may develop after an arterial switch operation (ASO). Aortic valve replacement has been the procedure of choice; however, valve‐sparing reimplantation has recently become more popular and demonstrates excellent long‐term outcomes. We report a case of neoaortic root dilatation and valve regurgitation due to an enlarged noncoronary cusp after ASO, for which we performed a valve‐sparing reimplantation using a cusp plication technique.PATIENT PROFILESA 13‐year‐old male was born with a transposition of the great arteries (TGA), ventricular septal defect (VSD), and coactation of the aorta. He underwent a balloon atrial septostomy at 13 days, followed by VSD patch closure and ASO at 19 days. Although he had no clinical complaints until the age of 13 years, follow‐up computed tomography showed a progressive dilation of the neoaortic root and sinus of Valsalva (Figure ). An echocardiogram revealed severe neoaortic valve regurgitation with an enlarged prolapsing non‐coronary cusp (NCC) (Figure A). This report was approved by the Institutional Review Board, and the written informed consent was obtained.Contrasted computed tomography. The dilated aortic root was replaced with a graft post‐operatively (arrow). Pre, pre‐operative, Post, post‐operativeEchocardiography images. An enlarged non‐coronary cusp was adjusted relative to the other cusps and neoaortic valve
