Prospective assessment after pediatric cardiac ablation: recurrence at 1 year after initially successful ablation of supraventricular tachycardia

Abstract

Recurrence after initially successful ablation occurs commonly in children. It is least common after AVNRT ablation and most common following ablation of right-sided pathways. These results serve as a benchmark for the time course of recurrence following initially successful ablation of supraventricular tachycardia in children.

2015 ACC/AHA/HRS Guideline for the Management of Adult Patients With Supraventricular Tachycardia

“…Several large series support the use of catheter ablation of the accessory pathway as first-line therapy in patients who have had AF and/or AVRT. These series report a success rate of approximately 93% to 95% and a 3% risk of major complications when patients are followed up for 6 months to 8 years 102,103,254,[276][277][278][279][280][281][282] (Table 8). AF in younger patients is usually associated with the accessory pathway and is unlikely to occur after ablation; in contrast, older patients may have recurrence of AF from causes unrelated to the accessory pathway.…”

Transcatheter cryoablation of tachyarrhythmias in children

“…Depending on which denominator one uses, this may suggest somewhere between 9% and 14% recurrence rates. Because the follow-up data are incomplete, a selection bias to follow-up in the recurrence patients would be a reasonable assumption, and thus the recurrence rate may not be dissimilar from the PAPCA experience of 7% and 9% at two and six months, respectively (25).…”

Recurrences of symptoms after AV node re-entrant tachycardia ablation: A clinical arrhythmia risk score to assess putative underlying cause

“…Slow pathway ablation has been shown to be very effective [10][11][12] and has both a high initial success rate and a low complication rate [13][14][15][16][17]. Although long-term AVNRT recurrence rate is low, the risk of persistent inappropriate sinus tachycardia [18,19] and atrial fibrillation (AF) or other atrial arrhythmias is increased after AVNRT ablation [20][21][22][23][24][25].…”
