Outcomes and Safety of Fluoroless Catheter Ablation for Atrial Fibrillation.

ABSTRACT:

Background

Intracardiac echocardiography and 3D mapping systems allow catheter ablation for atrial fibrillation (AF) to be conducted without fluoroscopy; however, the safety and effectiveness of fluoroless AF ablation are not well defined.

Methods

We examined consecutive radiofrequency AF catheter ablations at a large academic teaching hospital from November 2017 to July 2019. Outcomes for fluoroscopy-guided (N = 176) and fluoroless (N = 147) ablations were compared. Cases were designated as fluoroless at the outset of the procedure.

Results

Mean age was 59.5 ± 10 years, 66.9% were male, 71.8% had paroxysmal AF, and the mean CHA₂DS₂-VASc score was 1.7 ± 1.4. There were no differences in patient baseline characteristics. In the fluoroless group, m
