Why the study?
The short and midterm efficacy, safety, and reconnection patterns of the novel very high power very short duration 90 W approach compared to 50 W HPSD for AF ablation needed evaluation.
Does very high power very short duration (90 W) ablation improve efficacy and safety compared to 50 W ablation in patients undergoing first AF ablation?
Does very high power very short duration (90 W) ablation improve efficacy and safety compared to 50 W ablation in patients undergoing first AF ablation?
Very high power very short duration (90 W) AF ablation offers shorter ablation times but lower first-pass isolation and higher blanking period recurrences compared to 50 W, with similar 12-month efficacy.
No takes yet. Share an insight, caveat, or question.
Retrospective data suggest similar short-term efficacy and safety for 90 W vHPvSD versus 50 W HPSD AF ablation; leaves open confirmation in randomized trials.
