OBJECTIVE: The use of radiofrequency ablation of @entity943 in pediatrics requires demonstration that the technique is effective and devoid of significant complications. In this study we present our experience in the ablation of @entity943 in @entity1 and adolescents. @entity1 AND METHODS: Between January 1992 and January 1997 we performed a total of 1,543 radiofrequency ablation procedures. Of these, 130 were performed in 117 @entity1 younger than 18 years of age (58 were younger than 14 years old). Indication for ablation was the presence of drug refractory recurrent @entity4710 in 112 @entity1 and permanent ventricular preexcitation in 5 asymptomatic @entity1 . Final diagnosis in the 112 symptomatic @entity1 was: 4 @entity591 , 21 atrio-ventricular nodal reentrant @entity591 , 53 @entity3153 , 33 @entity591 using a concealed accessory pathway and 1 idiopathic left @entity1165 . RESULTS: The initial ablation procedure was effective in 109/117 @entity1 (93%) with a total duration of 90 +/- 31 minutes, using 16 +/- 11 minutes of radioscopy and a median of 4 radiofrequency applications. During follow-up, recurrence occurred in 9 @entity1 (8%). In 7 of them and in 6 of those with an unsuccessful initial procedure, a second effective procedure was performed in 11/13 @entity1 . Finally, radiofrequency ablation was effective in 111/117 @entity1 (95%). We observed a single complication in a 15 year old @entity1 who presented a @entity715 of the right femoral artery requiring balloon recanalization. Comparison of these results with those in the adult population showed no difference in terms of effectiveness, recurrences or complications. CONCLUSIONS: Radiofrequency ablation of @entity943 in pediatric and young @entity1 can be safely and effectively done. Results are similar to those obtained in adults suggesting that indications for ablation can also be similar.
