Visualization of multiple catheters with electroanatomical mapping reduces X-ray exposure during atrial fibrillation ablation
Why the study?
Does electroanatomic mapping with multiple catheter visualization reduce fluoroscopy time in patients with symptomatic refractory AF undergoing ablation?
Population
120 patients with symptomatic refractory atrial fibrillation (AF)
Comparison
Electroanatomic integration or electroanatomic… vs Conventional fluoroscopy alone during AF ablation
Design
RCT, randomly assigned

Implication
Minimizes radiation exposure in AF ablation; confirms RCT benefit of electroanatomic mapping with visualization over fluoroscopy alone.
Structured PICO
Does electroanatomic mapping with multiple catheter visualization reduce fluoroscopy time in patients with symptomatic refractory AF undergoing ablation?
P
Population
120 patients with symptomatic refractory atrial fibrillation (AF)
I
Intervention
Electroanatomic integration (n=40) or electroanatomic integration plus multiple catheter visualization (n=40) during AF ablation
C
Comparator
Conventional fluoroscopy alone (n=40) during AF ablation
O
Outcome
Total procedure time and total fluoroscopy timesurrogate
The use of electroanatomic mapping with multiple catheter visualization significantly reduces fluoroscopy time during atrial fibrillation ablation compared to conventional fluoroscopy.
