Why the study?
Does wall thickness-based adjustment of ablation index improve procedural efficacy and reduce 1-year AF recurrence in patients with atrial fibrillation undergoing pulmonary vein isolation?
Does wall thickness-based adjustment of ablation index improve procedural efficacy and reduce 1-year AF recurrence in patients with atrial fibrillation undergoing pulmonary vein isolation?
Tailoring ablation index based on wall thickness using intracardiac echocardiography improves procedural efficiency and reduces 1-year atrial fibrillation recurrence compared to a fixed ablation index.
Hypothesis-generating for wall thickness-guided ablation index in AF; randomized trials needed before practice change.
TAI increased acute procedure success, decreased time for PVI, and reduced the 1-year AF-recurrence rate, compared to FTI. Understanding the precise ablation target and tailoring AI would improve the efficacy of PVI.
