JinJiang ablation catheter is no inferior than Johnson ablation catheter in radiofrequency ablation of paroxysmal supraventricular tachycardia

Abstract

AbstractBackgroundParoxysmal supraventricular tachycardia (PSVT) is characterized by episodes of rapid tachycardia with sudden onset and sudden termination. PSVT treatment has evolved considerably over the past 30 years. Currently, radiofrequency catheter ablation is the first‐line treatment.HypothesisWe conducted a randomized controlled trial to compare safety and effectiveness of PSVT ablation between the Jinjiang and Johnson (J&J) catheters in 57 patients in our hospital.Methods and resultsPatients were randomly assigned to ablation procedures using either the Jinjiang system or the J&J Carto system. Follow‐up was performed 3 days, 1, and 6 months after the procedure. Success rate, ablation time, frequency of ablation, and rates of complications and recurrence did not significantly differ between the groups. One Jinjiang group patient (3.6%) experienced arrhythmia recurrence during the 6‐month follow‐up.ConclusionsThe Jinjiang catheter for radiofrequency ablation of PSVT is as safe and effective as the J&J catheter.
