Tested added ethanol vein treatment during repeat atrial fibrillation ablation
Part of Heart & circulation clinical trials.
This trial compares two ways to help stop atrial fibrillation during a repeat procedure: standard vein isolation only versus standard isolation plus an added medicine (ethanol) into the vein of Marshall. It aims to see whether the added step improves results when atrial fibrillation returns after a previous successful treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re over 18 years old.
- You’re scheduled for a repeat ablation because paroxysmal atrial fibrillation came back after a prior PVI.
- At the start of the study, testing shows your prior pulmonary vein isolation is still lasting.
- You do not have persistent atrial fibrillation (an ongoing form of AF, not brief episodes).
- You haven’t had certain prior heart ablation steps (including SVC/roofline/mitral line or vein of Marshall ethanol).
- No blood clots in the left atrium/left atrial appendage on pre-procedure scans, and your heart pumping strength is okay (left ejection fraction is at least 35%).

This trial tests two new treatments for persistent atrial fibrillation that came back after an initial procedure. One uses a targeted chemical injection, the other uses a special energy field to re-isolate the veins involved.
This study compares two treatments for paroxysmal atrial fibrillation (AF that comes and goes): using pulsed electric field ablation alone versus combining it with ethanol infusion into a specific vein. The goal is to see which approach works better for first-time ablation patients.
This study tests whether applying a small amount of alcohol to a specific heart vein (“vein of Marshall”) is safe and feasible during a standard atrial fibrillation (AF) ablation. It may help improve AF treatment, but the goal here is mainly to see if the approach can be done safely in the right patients.
This trial is testing a new approach to treat persistent atrial fibrillation (a type of irregular heartbeat) by combining standard catheter ablation with a special injection of alcohol (ethanol) into certain heart veins. It may help people whose symptoms haven't improved with medication.
This study tests a new way to find and treat the specific areas in the heart that cause atrial fibrillation to come back. It aims to improve the success of a repeat ablation procedure for people whose previous pulmonary vein isolation did not stop the irregular heartbeats.
This trial tests whether isolating the superior vena cava (a large vein carrying blood to the heart) during a repeat procedure helps people with atrial fibrillation (an irregular heartbeat) who have already had their pulmonary veins isolated. It aims to see if this extra step reduces the chance of the irregular heartbeat coming back.
