Cardiac single ventricle birth defects are a leading cause of death among birth defects for children under one years of age. Fontan palliation is the current clinical treatment for patients with these birth defects and result in a single working ventricle to power the entire system by forming a total cavopulmonary connection (TCPC). A significant number of patients with uni-ventricle Fontan circulation develop Fontan failure caused by the inability of the single ventricle to power the Fontan circulation. The use of mechanical cavopulmonary assist device has been proposed as a treatment for these patients.
