CV Grand Rounds — The Fontan Operation: Unanticipated Consequences

Mayo Clinic cardiologist, Alexander C. Egbe, M.B.B.S., discusses the unanticipated consequences of the Fontan operation. For more information on the Fontan operation, congenital heart disease or to request an appointment, visit here.

Fontan is a surgical procedure used in patients who are born with single ventricle physiology. The Fontan operation directly routes systemic venous return into the pulmonary circulation bypassing the subpulmonary vessel. The Fontan operation is not a cure and can come with unanticipated consequences later in life including atrial arrhythmia, thromboembolism and liver disease, which will require treatment and close follow-up with your physician.
