Redo Right Ventricular Outflow Tract Reconstruction in Adult Patients with Congenital Heart Disease

Between April 2005 and February 2019, 11 adult patients underwent redo reconstruction of the right ventricular outflow tract. The primary malformation was Fallot's tetralogy in 8, transposition of the great arteries in 2, and pulmonary atresia with intact ventricular septum in 1. Mean age at redo operation was 27.4 years. Right ventricular outflow tract was reconstructed with expanded polytetrafluoroethylene conduits with bulging sinuses and a fan-shaped valve in 9, transannular patch in 1, and right ventricular outflow patch in 1. There were no early and late deaths. One patient had residual branch pulmonary stenosis, while other 10 patients had no significant pulmonary stenosis and no significant pulmonary regurgitation. Signs and symptoms were improved in these 10 patients. Re-operation should be done before the development of right ventricular dysfunction, while it can be performed with satisfactory results in adult patients.
