Contact force sensing radiofrequency catheter ablation guided by electroanatomic mapping in pediatric patients with permanent junctional reciprocating tachycardia: A case series

Abstract

Limited data are available on the use of irrigated contact force (CF) catheters for radiofrequency (RF) ablation of permanent junctional reciprocating tachycardia (PJRT) in children. We considered five consecutive pediatric patients with diagnosis of PJRT who underwent RF ablation with irrigated CF catheter guided by electroanatomic mapping, obtaining a low number of RF pulses and minimal fluoroscopy exposure. High CF values are not necessary to obtain effective RF lesions and successful ablation.
