✦ Synopsis

We report the usefulness of a new 2-French (F) electrode catheter for perforating the atretic pulmonary valve in patients with pulmonary atresia and intact ventricular septum, using radiofrequency energy. The new 2-F electrode catheter was used in three patients. The first patient, weighing 2.1 kg, with pulmonary atresia and an intact ventricular septum, underwent transcatheter valvotomy at the age of 18 days. Due to massive left ventricular volume overload, the patient required surgical ligation of the ductus arteriosus, but she was discharged uneventfully after that. The second patient, weighing 2.2 kg, had Ebstein's anomaly with pulmonary atresia and an intact ventricular septum. She underwent transcatheter valvotomy at the age of 30 days. Although she was weaned from prostaglandin E 1 infusion, she died suddenly (presumed septicemic). A postmortem examination showed a split pulmonary valve. The third patient, weighing 2.3 kg, with pulmonary atresia and an intact ventricular septum, underwent transcatheter valvotomy at the age of 17 days. Prostaglandin E 1 infusion was discontinued on the 3rd day after the transcatheter valvotomy and she was discharged uneventfully. Cathet.
