Monday 24 November 2003

Right atrial-right ventricular conduit.

Definition: The Fontan procedure is a palliative surgical procedure used in children with complex congenital heart defects. It involves diverting the venous blood from the right atrium to the pulmonary arteries without passing through the morphologic right ventricle. It was initially described in 1971 as a surgical treatment for tricuspid atresia.
