For the reconstruction of the right ventricular outflow tract (RVOT) allografts show significantly better long-term durability than xenografts regardless of the age at implantation and the diameter.

The incidence of trivial or mild AI after the ASO is considerable and a progression over time is evident. However, severe AI and the need for AVR are rare. Patients with VSD or Taussig-Bing anomaly, and those with left ventricular outflow tract obstruction exhibit a higher risk of developing significant aortic insufficiency. Particularly patients who have developed an AI at 1 year after the ASO need to be under close observation.
