Aortic valve repair after arterial switch operation with autologous pulmonary artery wall.

Neoaortic valve repair after arterial switch operation can be challenging due to altered valve geometry and the absence of an ideal material for leaflet augmentation. We report repair of severe neoaortic valve regurgitation in a 22-month-old child using autologous pulmonary artery wall for cusp augmentation. A geometry-driven approach was applied, including augmentation of all cusps to increase coaptation surface and enlargement of the right sinus of Valsalva. This demonstrates feasibility of the neoaortic valve repair with autologous living pulmonary artery wall.
