Fontan procedure
Fontan Procedure
The Fontan Procedure (pronounced: fawn-tahn pro-see-jur) is a type of cardiac surgery performed to improve blood flow in individuals with a specific type of congenital heart defect known as single ventricle defects.
Etymology
The procedure is named after French surgeon Francis Fontan, who first described the operation in 1971.
Procedure
The Fontan Procedure involves redirecting the venous blood from the inferior vena cava and superior vena cava directly to the pulmonary arteries, bypassing the right ventricle. This allows the single functioning ventricle to pump oxygenated blood to the body, while the deoxygenated blood flows passively to the lungs.
Indications
The Fontan Procedure is typically indicated for patients with single ventricle defects, such as hypoplastic left heart syndrome, tricuspid atresia, or double inlet left ventricle.
Risks and Complications
Like all surgeries, the Fontan Procedure carries risks, including blood clot formation, arrhythmia, and heart failure. Long-term complications may include protein-losing enteropathy and plastic bronchitis.
