Why the study?
Is atrial fibrillation ablation using open-irrigated tip radiofrequency safe with an average intraprocedural ACT ≤210 seconds?
Is atrial fibrillation ablation using open-irrigated tip radiofrequency safe with an average intraprocedural ACT ≤210 seconds?
AF ablation using open-irrigated tip radiofrequency catheters can be performed safely with an average ACT ≤210 seconds, suggesting that traditional higher ACT targets may not be strictly necessary to prevent thromboembolic events.
No takes yet. Share an insight, caveat, or question.
May support lower ACT targets in irrigated-tip AF ablation; hypothesis-generating and requires randomized confirmation.
