Extracardiac Fontan is a preferred treatment strategy in many centers treating patients with single ventricle physiology, and many of these centers regularly include a fenestration between the extracardiac conduit and the common atrium. Spontaneous closure of the fenestration is a common complication of this technique and is independently associated with increased morbidity and mortality. Recently, we introduced a novel technique for fenestration of the extracardiac conduit wherein a pericardial patch is utilized at the fenestration point with excellent outcomes in the midterm fenestration patency rates, thus reducing the risk of acute post-Fontan complications.
