Key result
Autologous pulmonary artery wall augmentation proves feasible for severe neoaortic valve regurgitation in a child.
Why the study?
Neoaortic valve repair after arterial switch operation is challenging due to altered valve geometry and the lack of an ideal material for leaflet augmentation.
Case Report (n=1)
Autologous pulmonary artery wall can be feasibly used for cusp augmentation in neoaortic valve repair after arterial switch operation in pediatric patients.
Supports feasibility of autologous pulmonary artery augmentation for neoaortic repair in toddlers; hypothesis-generating and requires larger series before adoption.
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.

Konstantinov et al. (2026) conducted a case report in Severe neoaortic valve regurgitation after arterial switch operation (n=1). Neoaortic valve repair with autologous pulmonary artery wall was evaluated on Feasibility of neoaortic valve repair. Neoaortic valve repair using autologous pulmonary artery wall for cusp augmentation was feasible in a 22-month-old child with severe neoaortic valve regurgitation.
