Explain Fontan Operation ?

The original Fontan operation was done in a case where classical Glenn operation had been done (end-Lo-end anastomosis of superior vena cava and light pulmonary artery). The Fontan operation was completed by inserting a biological valve in the IVC - RA junction and a valved conduit between sight atrium and pulmonary artery. Later on Fonton operation was done diverting both SVC and IVC blood from right atrium through the conduit to Pulmonary artery without valves. There have been many modifications of Fontan procedure. Currently the procedure of choice is total cavopulmonary connection (TCPC).
