CATHETER CREATION OF AN OPEN OUTFLOW TRACT IN PREVIOUSLY ATRETIC RIGHT-VENTRICULAR OUTFLOW TRACT ASSOCIATED WITH VENTRICULAR SEPTAL-DEFECT

Pulmonary atresia with ventricular septal defect is a therapeutic challenge. Surgical creation of an aorto-pulmonary shunt, or palliative light ventricular (RV) outflow tract reconstruction is performed to increase pulmonary perfusion.1-3 Recently, transcatheter perforation, using a hot-up laser, and subsequent balloon dilatation was reported in pulmonary valve atresia.4 The interventional creation of a "neo-lumen" within a muscular RV atresia has been suggested to be beyond the scope of interventional cardiology. We report the results of radiofrequency perforation in 10 patients with muscular atresia of the RV outflow tract. © 1993.
