Fontan is a type of open-heart surgery to redirect the blood flow from the lower portion of the body directly to the lungs. It is usually performed to treat congenital heart abnormalities like, tricuspid atresia, hypoplastic left heart syndrome, and double-inlet ventricle. The inferior vena cava (IVC) and superior vena cava (SVC) are detached from the heart and routed directly to the pulmonary artery through a tube called conduit. A small hole is made between the conduit and the right atrium that lets the blood flow directly to the heart until the lungs get used to the extra flow from the lower part of the body.
