Irrigated contact force sensing catheter for redo ablation of slow-fast atrioventricular nodal reentrant tachycardia in pediatric and adolescent patients: A case series

Conventional nonirrigated catheters cannot be able to create adequate lesions for effective slow pathway modulation in certain cases of pediatric atrioventricular nodal reentrant tachycardia ablation. Irrigated contact force sensing catheters may be considered in pediatric and adolescent patients to obtain a more extensive slow pathway modulation for redo ablation, avoiding dangerous radiofrequency applications close to the compact atrioventricular node or complex left-sided procedures.
