Fontan Procedure

A Fontan procedure is a series of surgical steps that is used to correct tricuspid atresia. Tricuspid atresia is a condition that is characterized by a small ventricular septal defect (VSD), an atrioventricular septal defect (ASD), and a small pulmonary valve. These defects result in low oxygen levels. To correct this, a bi-directional Glen shunt is performed. This removes the superior vena cava from the right atrium and attaches it to the pulmonary artery. The right atrium is then attached to the pulmonary artery. An internal baffle then directs blood from the inferior vena cava into the pulmonary artery. This blood then flows to the lungs and improves oxygenation of the body.
