Neonatal tetralogy of Fallot with doubly committed ventricular septal defect and severe pulmonary valvar stenosis: A contraindication for catheter intervention?

Abstract

Balloon dilation of the pulmonary valve is regarded as the treatment of choice for isolated pulmonary valvar stenosis. This technique can also be performed palliatively, delaying surgical treatment in neonates with tetralogy of Fallot (TOF) and severe pulmonary valvar stenosis. 1 We report a case of TOF and a doubly committed ventricular septal defect (VSD) in which pulmonary valvar stenosis was balloon dilated. This led to the rupture of the adjacent aortic sinus wall and development of significant aortic regurgitation.
