Effect of Electroanatomically Guided Versus Conventional Catheter Ablation of Typical Atrial Flutter on the Fluoroscopy Time and Resource Use: A Prospective Randomized Multicenter Study
Why the study?
Does electroanatomically guided catheter ablation reduce procedure duration and fluoroscopy exposure time compared to conventional ablation in patients with typical atrial flutter?
Population
210 patients with documented typical atrial flutter, mean age 63 +/- 10 years, 169 men and 41 women.
Comparison
Electroanatomically guided mapping and catheter… vs Conventional catheter ablation strategy
Design
RCT, randomized
Follow-up
6 months

Implication
Supports electroanatomic guidance to limit radiation in atrial flutter ablation; extends RCT evidence for mapping systems.
Structured PICO

I
Intervention
Electroanatomically guided mapping and catheter ablation (Carto)
C
Comparator
Conventional catheter ablation strategy
O
Outcome
Procedure duration and fluoroscopy exposure time
Electroanatomically guided ablation for typical atrial flutter significantly reduces fluoroscopy exposure time by almost 50% compared to conventional ablation, but increases procedural costs.
