Doubly committed subarterial ventricular septal defect: A risk factor for aortic distortion in patients considered for percutaneous pulmonary valve implantation?

Percutaneous pulmonary valve implantation has gradually become the first line strategy for re-intervention for right ventricular outflow tract dysfunction during long-term follow-up after congenital cardiac surgery in many centers. We describe a case of a patient with double outlet right ventricle (Fallot's type) with a doubly committed subarterial ventricular septal defect, where the unique anatomy precluded percutaneous pulmonary valve implantation.
