In medical practice, atrial fibrillation (AF) is intricately associated with heart failure (HF). Currently, ethanol infusion of vein Marshall (EIVOM) for AF ablation in HF patients remains significantly limited. This was a non-randomized, single-center, retrospective observational study. received 4-step composed EIVOM, pulmonary isolation (PVI) and linear ablation. The primary composite endpoint defined as recurrence tachycardia over 30 s. Propensity score matching (PSM) performed to reduce selection bias. From April 2020 May 2022, 362 were included, comprising 182 180 non-HF patients. EIVOM success rate lower than (86.8% vs. 93.9%). Cardiac effusion more common (44.0% 37.2%), 2 cases atrial-esophageal fistula observed the group. During median follow-up 12 months, no significant difference between Different subgroups had similar recurrence. After PSM, remained statistically equivalent groups. EVIOM combining catheter can be completed comparable or without HF. However, peri-procedural safety concern undergoing combing follow-up, status before not related increased
