 The addition of afterload rPAB to a normal-functioning right ventricle in the setting of end-stage dilated cardiomyopathy shifts the inter-ventricular septum toward the midline, thus significantly improving left ventricular geometry and function. It permits the infant or young child to operate from a much improved position on Starlings curve with gradual resolution of congestive heart failure and the potential for lethal ventricular dysrhythmia. An abundance of progenitor myocytes known to exist within the myocardium of this patient age group may then contribute to permanent left ventricular restoration.
