Key result
A standardized step-by-step guide outlines vein of Marshall ethanol infusion as an adjunctive strategy to enhance ablation efficacy and reduce recurrence in persistent atrial fibrillation.
Why the study?
Pulmonary vein isolation alone has limited success in treating persistent AF, prompting adjunctive strategies such as vein of Marshall ethanol infusion to improve outcomes.
This step-by-step guide provides a reproducible framework for electrophysiologists to integrate VOM ethanol ablation into clinical practice for complex AF patients.
Standardized VOM ethanol infusion protocol may aid persistent AF ablation; leaves open efficacy confirmation in randomized trials.
Pulmonary vein isolation (PVI) alone has limited success in treating persistent atrial fibrillation (AF), prompting the use of adjunctive strategies like vein of Marshall (VOM) ethanol infusion to improve outcomes. This step-by-step guide outlines a standardized approach for VOM ethanol infusion, including venous access, coronary sinus cannulation, VOM identification, and ethanol infusion via an over-the-wire balloon catheter. Ethanol infusion enhances ablation efficacy, reducing AF recurrence and improving the likelihood of durable mitral isthmus block. By providing a reproducible framework, this guide helps electrophysiologists integrate VOM ethanol ablation into clinical practice, optimizing rhythm control strategies for complex AF patients.
