Q. True regarding Fontan surgery? A. Bidirectional glenn shunt is usually done within 1 week of birth B. PA banding may be required in patients with significant pulmonary stenosis prior to glenn surgery C. Fenestration decreases post-op pleural effusion D. Peri-operative mortality is around 20% Answer: C. Fenestration decreased post-op pleural effusion Explanation: Fontan surgery is type of single ventricular repair required for some complex congenital heart diseases. It is a multistaged procedure. Also known as Total cavopulmonary connection (TCPC). It separates systemic and pulmonary circulation. 1 st stage procedure is done to normalize pulmonary blood flow (BT shunt in case of decreased pulmonary blood flow situations like PS and PA band in case of increased pulmonary blood flow situations). 2 nd stage is called bidirectional glenn shunt (BDG) or Hemifontan which is done at the age of 4-6 months and final stage is completion of Fontan Advantages:
