The surgical creation of a Potts shunt has been reported in children with suprasystemic idiopathic pulmonary artery (PA) hypertension (IPAH) refractory to any medical therapy. This surgical approach allows acute decompression of the right ventricle (RV) and thereby avoids ventricular failure. We present 4 newborns and infants with different causes of pulmonary hypertension (PH) in whom interventional stenting of the patent ductus arteriosus (PDA) was used to create a "functional" Potts shunt.
