Key result
The CARTO 3 non-fluoroscopic navigation system significantly reduced mean fluoroscopy time during atrial fibrillation ablation compared to the CARTO XP system (15.9 vs 26 minutes; P<0.001).
Why the study?
Does the CARTO 3 System reduce fluoroscopy exposure compared to the CARTO XP system during catheter ablation in patients with drug refractory atrial fibrillation?
Population
240 patients with drug refractory atrial fibrillation undergoing catheter ablation

The CARTO 3 electroanatomical navigation system significantly reduces fluoroscopy exposure during atrial fibrillation ablation compared to the previous generation system.
Stabile et al. (2011) conducted an observational in Drug refractory atrial fibrillation (n=240). CARTO 3 system vs. CARTO XP system was evaluated on Mean fluoroscopic time (minutes) (p=< 0.001). The CARTO 3 non-fluoroscopic navigation system significantly reduced mean fluoroscopy time during atrial fibrillation ablation compared to the CARTO XP system (15.9 vs 26 minutes; P<0.001).
