METHODS: One hundred twenty nine atrial ablation cases wherein VOM ethanol infusion was attempted were identified from the time of the program\'s inception in 2019 at Maine Medical Center (Portland, ME). Our technical approach, procedural success, and complications were adjudicated from the medical record.
RESULTS: The overall VOM ethanol infusion success was 90%. Infusion success rates improved and fluoroscopy utilization decreased with experience. Arrhythmia recurrence was 14% after a mean follow-up of 9.5 months. Complications occurred in 5.4% of patients, including a 3.1% risk of delayed tamponade.
CONCLUSIONS: In our single center experience, VOM ethanol infusion was feasible with a high technical success rate. These positive results are balanced against a concerning rate of delayed tamponade.
