Why the study?
Does open irrigated tip catheter ablation at 50 W using perpetual motion improve cure rates without increasing complications in patients undergoing atrial fibrillation ablation?
Population
1,122 ablations for atrial fibrillation (including paroxysmal and persistent AF)
Comparison
Open irrigated tip catheters at 50 W using… vs Closed tip catheters and OITC at lower powers
Design
Cohort

Higher-power OITC may improve persistent AF outcomes; leaves open randomized confirmation of efficacy and safety.
Does open irrigated tip catheter ablation at 50 W using perpetual motion improve cure rates without increasing complications in patients undergoing atrial fibrillation ablation?
Using open irrigated tip catheters at 50 W with perpetual motion improves cure rates for persistent AF and reduces procedure times without increasing complications.
