[Long-term results of the Ross procedure].
Aortic valve replacement with a pulmonary autograft (Ross procedure) was pioneered by Donald Ross in 1967. The advantages of the autograft valve include freedom from anticoagulation, hemolysis, and infection, optimal hemodynamic performance, and growth potential. Various materials have been used for the right ventricular outflow tract (RVOT). Currently, a cryopreserved pulmonary allograft is accepted worldwide as a useful material for this procedure. Pulmonary allografts cannot be utilized in Japan, and thus other valves and materials must be used instead. The acceptance of these procedures has been slow because of the technical demands of the operations and the inherent need for reconstruction of the RVOT, thereby placing two valves at risk. In the past 20 years, the Ross procedure has been increasingly considered for pediatric patients with a wide spectrum of congenital abnormalities.
