Not Applicable
Completed
Conditions
Atrial Fibrillation Paroxysmal
Registration Number
NCT05711589
Lead Sponsor
Pusan National University Hospital
Brief Summary

This study aimed to investigate safety and efficacy of intracardiac echocardiography (ICE)-guided zero-fluoroscopic cryoballoon ablation (CBA) in patients with paroxysmal atrial fibrillation.

Detailed Description

Patients (n=100) undergoing de novo CBA for paroxysmal AF were randomly assigned (1:1) to zero-fluoroscopic (Zero-X) and conventional fluoroscopy groups.

Radiation exposure, procedural time, acute and long term outcome were analyzed.
