4.2 | The feasibility of PVI
Durable PVI is the cornerstone for PeAF ablation.9 The
efficacy and safety of PVI with PFA in paroxysmal AF had been
demonstrated absolutely in previous studies.7,8 In our
study, the acute successful PVI of PFA was excellent despite the
unsatisfying PVI durability which might be due to inadequate contact of
the circular PFA catheter located at the anterior or posterior carina in
PV. The utilization of a steerable sheath may be a promising approach to
improve the contact of the circular PFA catheter. Thus, ensuring stable
PFA catheter contact, along with adequate energy delivery and sufficient
applications, is crucial to enhance PVI durability.
