Modified Fontan Conversion: An Alternative Technique for Adult Patients.

A need persists for Fontan conversion that provides alternative approaches for the individual anatomical challenges occurring in these unusual and complex adult patients. The pulmonary arteries present unique variations and the surgical technique needs to be intraoperatively addressed. We describe a technique for Fontan conversion for performing the distal anastomosis of the extracardiac conduit, allowing adequate matching to the pulmonary arteries and preserving an optimal flow into the Fontan circuit.
