“…In the adult population, similar recurrence rates have been reported in RMN and MAN ablation, which were also comparable between these two techniques, corresponding with the current study’s findings [19] , [20] . Recently published large European and Japanese pediatric CA registries, including primarily manual-guided RF and few cryoablation procedures, reported much higher 12-month recurrence rates compared to our findings, for AVNRT as well as for AVRT ablation [2] , [3] . Moreover, a higher recurrence rate in cryoablation compared to non-irrigated RF ablation was also observed in one of these registries, whereas the other did no comparison between energy sources [2] , [3] .…”

Theoretically, the observed differences between cryoablation and RF ablation could be caused by either energy source, catheter stability and/or (mis)identification of the right target.…”

“…AP’s occur at a variety of locations, of which left lateral is the most frequently observed site [18] . Ablation of left lateral located AP’s yields high acute and long-term success rates, whereas right free wall and septal located AP’s are more difficult to ablate [2] , [3] , [18] . This is consistent with our findings.…”

“…In children without structural heart disease, the majority of supraventricular tachyarrhythmias (SVT) consist of atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) [1] , [2] , [3] . Catheter ablation (CA) in pediatric cardiology has been used as treatment of these SVT since 1990 [1] , [4] .…”

Background Catheter ablation (CA) is the first-choice treatment for tachyarrhythmia in children. Currently available CA techniques differ in mechanism of catheter navigation and energy sources. There are no large studies comparing long-term outcomes between available CA techniques in a pediatric population with atrioventricular reentry tachycardia (AVRT) or atrioventricular nodal reentry tachycardia (AVNRT) mechanisms. Objective This study aimed to compare procedural and long-term outcomes of remote magnetic navigation-guided radiofrequency (RF) ablation (RMN), manual-guided RF ablation (MAN) and manual-guided cryoablation (CRYO). Methods This single-center, retrospective study included all first consecutive CA procedures for AVRT or AVNRT performed in children without structural heart disease from 2008 to 2019. Three study groups were defined by the ablation technique used: RMN, MAN or CRYO. Primary outcome was long-term recurrence of tachyarrhythmia. Results In total, we included 223 patients, aged 14 (IQR 12–16) years; weighting 56 (IQR 47–65) kilograms. In total, 108 procedures were performed using RMN, 76 using MAN and 39 using CRYO. RMN had significantly lower recurrence rates compared to MAN and CRYO at mean follow-up of 5.5 ± 2.9 years (AVRT: 4.3% versus 15.6% versus 54.5%, P < 0.001; AVNRT: 7.7% versus 8.3% versus 35.7%, P = 0.008; for RMN versus MAN versus CRYO respectively). In AVNRT ablation, RMN had significantly lower fluoroscopy doses compared to CRYO [30 (IQR 20–41) versus 45 (IQR 29–65) mGy, P = 0.040). Conclusion In pediatric patients without structural heart disease who underwent their first AV(N)RT ablation, RMN has superior long-term outcomes compared to MAN and CRYO, in addition to favorable fluoroscopy doses.

Background: Radiofrequency ablation (RFA) is the standard method of treatment for tachyarrhythmias in school children, and it leads to complete recovery in children without structural heart disease. However, RFA in young children is limited by the risk of complications and unstudied remote effects of radiofrequency lesions.Objective: To present the experience of RFA of arrhythmias and the results of followup of younger children. Materials andMethods: RFA procedures (n = 255) were performed in 209 children with arrhythmias from 0 to 7 years old. The arrhythmias were presented with atrioventricular reentry tachycardia with Wolff-Parkinson-White (WPW) syndrome (56%), atrial ectopic tachycardia (21.5%), atrioventricular nodal reentry tachycardia (4.8%), and ventricular arrhythmia (17.2%). Results:The overall effectiveness of RFA, considering the repeated procedures performed due to the primary ineffectiveness and recurrencies, was 94.7%. There was no mortality associated with RFA in patients, including young patients. All cases of "major" complications are associated with RFA of the left-sided accessory pathway and tachycardia foci and are represented by the mitral valve damage in three patients (1.4%). Tachycardia and preexcitation recurred in 44 (21%) patients. There was a correlation between recurrences and parameters of RFA (odds ratio 0.894; 95% confidence interval: 0.804-0.994; p = .039). Reducing the maximum power of effective applications in our study increased the risk of recurrence. Conclusion:The use of the minimum effective parameters of RFA in children reduces the risk of complications, but increases arrhythmia recurrence rate.
