We report a modified technique of wire atrial septostomy (WAS) with a reverse transseptal puncture (TSP) in an infant case of pulmonary atresia with intact ventricular septum. A radiofrequency (RF) wire was advanced to the septum through a 4 Fr pigtail catheter hooked on the left side of atrial septum and RF energy was applied while advancing the wire across the septum. Following that reverse TSP, WAS was performed to cut the septal tissue using a 0.010 microwire and RF wire. The atrial septum defect (ASD) was enlarged to a size of 1
