Background: We aimed to evaluate the acute and long-term efficacy and safety of radiofrequency catheter ablation (RFCA) in Chinese pediatric patients with arrhythmias. Methods: We gathered clinical data from pediatric patients who underwent RFCA in several large medical centers in China between 2000 and 2019. Results: A total of 4,622 different substrates in 4,622 patients were ablated, with the majority consisting of supraventricular tachycardia (N = 3,831, 82.9%) and ventricular arrhythmias (VAs) (N = 791, 17.1%). The majority of supraventricular tachycardia (SVT) consists of atrioventricular reentry tachycardia (AVRT) (N = 2,492, 65.0%) and atrioventricular nodal reentry tachycardia (AVNRT) (N = 1,075, 28.1%). The accessory pathway location was left-sided in 1,237(49.7%) and right-sided in 1,251(50.3%) of the 2,488 pathways. The VAs consist of premature ventricular contraction (PVC) (N = 597, 75.5%) and ventricular tachycardia (VT) (N = 194, 24.5%). The duration of follow-up ranged from 1 month to 1 year. The overall acute/long-term success rate of RFCA was 96.4%/92.2%, AVRT 97.8%/93.5%, AVRT 99.3%/95.0, PVC 98.1%/92.2%, and VT 81.3%/75.2%. Serious complications occurred in 29 patients (0.6%). Conclusions: This present study shows that RFCA is effective and safe in the treatment of arrhythmias in Chinese pediatric patients, with a high success rate exceeding 90%, low recurrence rate, and significantly reduces the risk of complications. The success rate of left-sided pathway ablation is slightly higher than that of the right-sided pathway. There is no difference in the success rate of RFCA among children of different ages. It could be the first-line therapy in the majority of pediatric patients with SVT and/or VAs.

AbstractBackgroundTo compare potential risk factors for complications and recurrence after radiofrequency catheter ablation in symptomatic atrioventricular reentrant tachycardia in children and adolescents.MethodsWe retrospectively reviewed the data of 213 consecutive patients with symptomatic atrioventricular reentrant tachycardia who underwent both electrophysiological study and radiofrequency catheter ablation, divided these patients into two groups, children (age <12 years) and adolescents (12 ≤ age < 18 years), and compared the location of the accessory pathway, success rate, recurrence rate, complications, presence of congenital heart disease, presence of intermittent ventricular pre-excitation, and presence of Wolff–Parkinson–White syndrome in the two groups.ResultsThe position of the accessory pathway was mostly right sided in children (61.3%) and left sided in adolescents (61.5%). Children had significantly more congenital heart disease than adolescents (6.4% versus 0.8%). Univariate analysis showed children or adolescents with right-sided accessory pathways to be 6.84 times and those with accessory pathways on both sides of the septum 25 times more likely to relapse than those with a single accessory pathway. Multivariate analysis indicated that children or adolescents with two accessory pathways were six times, and those with intermittent ventricular pre-excitation nine times more at risk of relapsing following radiofrequency ablation than those with single accessory pathways. All five complications occurred in children.ConclusionsThe findings suggest that the position and number of accessory pathways and presence of intermittent ventricular pre-excitation are related to risks of recurrence of atrioventricular reentrant tachycardia in children and adolescents.

Radiofrequency lesions can, theoretically, be the substrate for new persistent arrhythmias. As far as we know, this has never previously been encountered after transcatheter ablation of accessory pathways. A child with Wolff–Parkinson–White syndrome was referred for radiofrequency catheter ablation of a left-sided accessory pathway. After successful ablation of the accessory pathway using a retrograde transaortic approach, the child developed an incessant wide QRS complex tachycardia at slow rate that was resistant to pharmacologic interventions. The focus of the tachycardia was identical to the ventricular site of insertion of the eliminated accessory pathway.

Abstract Radiofrequency catheter ablation of parahisian accessory pathways in pre-excitation syndrome is a challenging task, due to the extremely high risk of complete atrioventricular block. In this brief report we describe the case of a 32 year-old man presenting a parahisian accessory pathway, who has been successfully treated by radiofrequency ablation. Radiofrequency catheter ablation using low-power radiofrequency current is considered to be the most appropiate method of ablation in adult patients.
