Why the study?
Pulmonary arterial hypertension remains a progressive, life-threatening condition despite advances in medical treatments.
Does interventional stenting of a closed ductus arteriosus improve clinical status and right ventricular function in a child with severe pulmonary arterial hypertension?
Does interventional stenting of a closed ductus arteriosus improve clinical status and right ventricular function in a child with severe pulmonary arterial hypertension?
Interventional creation of a reverse Potts shunt by stenting a closed ductus arteriosus is a feasible approach that can improve right ventricular function in severe pediatric pulmonary arterial hypertension.
Pulmonary arterial hypertension remains a progressive, life-threatening condition despite advances in medical treatments. We report the first case of the interventional creation of a reverse Potts shunt by stenting a closed ductus arteriosus in a four-year-old child with right ventricular failure due to suprasystemic pulmonary arterial hypertension associated with Von Hippel-Lindau disease, unresponsive to triple anti-pulmonary arterial hypertension therapy. Following the procedure, the patient's clinical status and echocardiographic systolic and diastolic right ventricular function improved.
