Feasibility of Ethanolization of Vein of Marshall With Specific Catheter in Atrial Fibrillation Ablation — Innov Marshall  

Atrial Fibrillation Clinical Trial

Official title:
Prospective Single-centre Study to Evaluate the Feasibility of Ethanolization of Vein of Marshall With a Specific Catheter in the Ablation of Atrial Fibrillation

Clinical Trial Summary

In patients with persistent AF (PsAF), ablation limited to pulmonary vein (PV) isolation is the most straightforward approach, but results only in 50% of arrhythmia freedom at 1 year follow-up. Substrate modification strategies have failed to demonstrate their superiority with variable reported success rate. The Marshall network is a highly arrhythmogenic structure that has not been systematically targeted so far, probably because of the absence of dedicated tools to make its ablation simple and easy. We sought to investigate the use of a specific catheter for visualization and ethanolization of vein of Marshall allowing to systematically include this target in the ablation set. The main objective of this study is to demonstrate the feasibility to use the Targeted Endovascular Delivery (TED) catheter specifically for visualization and ethanolization of vein of Marshall.
