Comparative Study Between Cryoablation and Radiofrequency Ablation in the Treatment of Supraventricular Tachycardia

CRYOthermy and Radiofrequency ABLation For AVNRT TrEatment

• Status: Unknown
• Phase: Phase 4
• Study type: Interventional
• Enrollment: 520 (estimated)
• Sponsor: Princess Margaret Hospital, Hong Kong · Other Government
• Sex: All
• Age: 18 Years – 80 Years
• Healthy volunteers: Not accepted

Summary

The purpose of this study is to compare the safety and effectiveness of cryoablation and radiofrequency ablation in the treatment of the commonest kind of supraventricular tachycardia, namely atrioventricular nodal reentrant tachycardia. The study hypothesis is that cryoablation is non-inferior to radiofrequency.

Conditions

• Supraventricular Tachycardia
• Atrioventricular Nodal Reentrant Tachycardia

Interventions

Type	Name	Description
PROCEDURE	cryoablation	cryoablation with an 8mm-tip catheter
PROCEDURE	radiofrequency ablation	radiofrequency ablation with a 4mm-tip catheter
