Fontan Surgery
The Fontan operation is an open-hearted method of surgery. Let blood from the bottom of the body go straight into the lungs. This helps the blood to consume oxygen without going through the heart
Low-oxygen blood from the lower part of the body combines with high-oxygen blood in babies with hypoplastic left heart syndrome The low-oxygen blood and high-oxygen blood no longer combine after the Fontan operation. It helps the heart to only pump high-oxygen blood to the body.
The patch that was placed in the right upper chamber is removed. A wall, called a baffle, is built in the right upper chamber. The baffle guides the blue blood coming from the lower body into the blood vessels that go to the lungs. A small hole, called a fenestration, is made in the baffle. This allows a small amount of blue blood to go across the baffle into the right upper chamber.
