Konno procedure using atrioventricular groove patch plasty after arterial switch operation.
A patient with transposition of the great arteries accompanied by Shaher type 9 coronary anatomy experienced the development of progressive neoaortic valvular regurgitation with a small annulus, supravalvular stenosis, and neopulmonary valvular and supravalvular stenoses 15 years after an arterial switch operation. To implant a prosthetic valve clinically adequate in size, the Konno procedure was necessary. However, the right coronary anatomy precluded the original Konno procedure. My colleagues and I accomplished neoaortic anterior annular enlargement in this case by using atrioventricular groove patch plasty without jeopardizing the right coronary artery, and this resulted in a satisfactory outcome.
