Diverts the venous blood from the right atrium (deoxygenated blood returns to the heart from the body) to the pulmonary arteries (carry blood from heart to lungs) without passing through the morphologic pulmonary ventricle. Used when a congential heart defect result in the formation of a heart with only one ventricle. The procedure allows oxygenation of blood by lungs.
It was initially described in 1971 by Dr Fontan and Dr Kreutzer separately as a surgical treatment for tricuspid atresia.
