Key result
Use of a contact force-sensing catheter with an advanced catheter location system during AF ablation significantly reduced median fluoroscopy time (9.5 vs. 41 min, P<0.001) compared to control.

The use of a contact force-sensing catheter with advanced catheter location during AF ablation significantly reduces fluoroscopy time and radiation dose without increasing complications.
Lee et al. (2015) conducted a cohort in Atrial fibrillation (n=1,515). Contact force-sensing catheter with advanced catheter location system vs. Atrial fibrillation ablation without this technology was evaluated on Total fluoroscopy time (min) (p=<0.001). Use of a contact force-sensing catheter with an advanced catheter location system during AF ablation significantly reduced median fluoroscopy time (9.5 vs. 41 min, P<0.001) compared to control.
