Key result
Driver ablation terminates persistent AF lasting under six months, keeping ~85% AF-free at one year.
Why the study?
Does catheter ablation targeting noninvasively mapped driver domains reduce radiofrequency delivery time and improve outcomes compared to stepwise ablation in patients with persistent atrial fibrillation?
Does catheter ablation targeting noninvasively mapped driver domains reduce radiofrequency delivery time and improve outcomes compared to stepwise ablation in patients with persistent atrial fibrillation?
Ablation targeting noninvasively mapped driver domains in persistent AF achieves similar 12-month freedom from AF as stepwise ablation but requires significantly less radiofrequency delivery time.
No takes yet. Share an insight, caveat, or question.
May reduce RF delivery time in persistent AF; extends observational driver data but leaves open randomized comparisons to stepwise ablation.
Haïssaguerre et al. (2014) studied this question. Driver ablation terminated 75% of persistent AF in patients with AF lasting up to 6 months, with 85% free from AF at 12 months post-ablation.
