“…IFLVTs, unlike the majority of IVTs, are classically sensitive to verapamil because of its effect on the slow inward calcium channel, which is thought to be critical to the propagation of the arrhythmia . Intravenous adenosine, electrical cardioversion, and β-blockers are largely ineffective at terminating IFLVT because of lack of effect on the slow inward calcium channel.…”

Objective:Fascicular tachycardia is a common form of sustained idiopathic left ventricular tachycardia. This study aimed to achieve successful results with catheter ablation procedures performed through three-dimensional electroanatomic mapping using near-zero fluoroscopy in fascicular tachycardia patients.Methods and results:In this study, we included 33 consecutive children with fascicular tachycardia, for whom we performed a transcatheter radiofrequency ablation procedure using the EnSite® system. Activation mapping was performed in all patients during tachycardia, and the earliest presystolic purkinje potentials were the target site for radiofrequency lesions.Results:Twenty-five patients were male, and eight were female. The mean weight of the patients was 39.6 ± 10.4 kg, and the mean age was 13.6 ± 2.5 years. The mean procedure time was 121.3 ± 44.3 minutes. The mean follow-up period was 18.4 ± 6.5 months. No fluoroscopy was needed in 30 patients. The mean fluoroscopy time in the remaining patients was 166.6 ± 80 seconds. All of the patients had left posterior fascicular tachycardia except for one who had left anterior fascicular tachycardia. The acute success rate was perfect (100%). No patients developed left bundle branch block or complete atrioventricular block. Recurrence developed in one patient.Conclusion:We suggest that radiofrequency ablations via an electroanatomic mapping system are quite safe and effective, with high success rates in paediatric patients with fascicular tachycardia. This method has the advantage of avoiding ionising radiation exposure for both the patient and operator, thus reducing the lifetime risk of malignancy in the paediatric population.
