The Fontan Procedure is a surgical operation that is performed on patients with complex congenital heart defects. While the procedure is commonly known by its official name, there are several synonyms that are used to refer to it in medical literature and discussions. Some of these synonyms include the Fontan Operation, Fontan Palliation, and Total Cavopulmonary Connection. These terms all refer to the same surgical technique, which involves redirecting the flow of blood from the lower body to the lungs without the need for a functioning right ventricle. While the terminology may vary, the goal of the Fontan Procedure remains the same: to improve the quality of life for individuals with complex heart defects.
