Key result
Vein of Marshall ethanol infusion is reviewed regarding its mechanisms, procedural aspects, and outcomes as an adjunct to pulmonary vein isolation in patients with persistent atrial fibrillation.
Why the study?
Pulmonary vein isolation is less effective for persistent AF, and the vein of Marshall can serve as an AF trigger source and tract for autonomic nerves.
Does vein of Marshall ethanol infusion as an adjunct to pulmonary vein isolation improve outcomes in patients with persistent atrial fibrillation?
Does vein of Marshall ethanol infusion as an adjunct to pulmonary vein isolation improve outcomes in patients with persistent atrial fibrillation?
This review summarizes the mechanisms, procedural aspects, and outcomes of vein of Marshall ethanol infusion as an adjunctive treatment for persistent atrial fibrillation.
May support adjunctive use in persistent AF ablation; leaves open confirmation of outcome benefit in randomized trials.
Catheter ablation has become a cornerstone treatment for atrial fibrillation (AF). Pulmonary vein isolation is the accepted approach for paroxysmal AF ablation, but it is less effective for persistent AF. The vein of Marshall (VOM) is located in the epicardial left atrium and can be a source of AF triggers as well as a tract for autonomic nerves. It directly communicates with the underlying myocardium, including the left atrial ridge and the posterior mitral isthmus. This review discusses the latest evidence regarding the mechanisms, procedural aspects, and outcomes of VOM ethanol infusion when used as an adjunct to pulmonary vein isolation in patients with persistent AF.
