Antiarrhythmic surgery (ventriculotomy) was used in our institution between 1973 and 1980 to treat 15 patients with Arrhythmogenic Right Ventricular Dysplasia (ARVC/D) who had ventricular tachycardia (VT) resistant to antiarrhythmic drug therapy. When catheter ablative procedures became available, we used fulguration (F) with DC energy shock alone in 27 patients between August 1983 and February 1992. However, this technique was associated with serious complications. The causes of these complications are now understood and the problems associated with F have been corrected. We now use radiofrequency (RF) energy followed by F if RF ablation is not successful. This protocol has been used in 23 patients from 1992 until October, 1999. The results of ablation using these two approaches over 16 years has been reported [1]. We wish to report our most recent experience with 22 additional patients over 6 years using the combined treatment with RF ablation immediately followed by the use of F if necessary.
