Forty-seven catheter ablation procedures for intra-atrial reentry tachycardia were performed in 40 patients with palliated congenital heart disease. The acute success rate was 87% and the recurrence rate was 34% during an average follow-up of 36 months. Of those patients who had recurrence, 88% did so within 1 year of ablation. Of the 23 patients who were free of recurrence 1 year after ablation, 21 (91%) remain free from recurrence at an average of 45 months (median 39; range 15 to 88) after ablation.
