Early Balloon Dilatation of the Pulmonary Valve in Infants With Tetralogy of Fallot

Abstract

Pulmonary valve dilatation in infants with tetralogy of Fallot is a relatively safe procedure and appears to produce adequate palliation in most patients. It allowed the growth of the pulmonary annulus and of the pulmonary arteries, resulting in a mean gain of 2 SD for those structures.
