Laser or radiofrequency pulmonary valvotomy in neonates with pulmonary atresia and intact ventricular septum—description of a new method avoiding arterial catheterization

Abstract

SummaryWe describe a new method of transvenous laser or radiofrequency perforation of the pulmonary valve with subsequent balloon pulmonary valvoplasty. The technique obviates the need for arterial catheterisation and considerably shortens the time needed for the procedure. Uncomplicated and successful relief of pulmonary valvar atresia was achieved in both patients attempted, although one ultimately required a Blalock-Taussig shunt because of increasing muscular obstruction of the right ventricular outflow tract.
