Isolating the superior vena cava in repeat atrial fibrillation ablation
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are older than 18 years.
- You have been diagnosed with paroxysmal atrial fibrillation (an irregular heartbeat that comes and goes) that keeps coming back.
- You have had a previous procedure to isolate your pulmonary veins (the veins that bring blood from your lungs to your heart) as the only treatment for your atrial fibrillation.
- At your repeat procedure, your pulmonary veins are still isolated (no reconnection).
- You are not pregnant and are willing to participate in the study.

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 studies a modified ablation procedure that targets the superior vena cava in addition to the pulmonary veins to help stop episodes of paroxysmal (coming and going) atrial fibrillation. It may help people whose symptoms continue despite antiarrhythmic medicines.
This study tests a new type of ablation (pulsed field ablation) for people with atrial fibrillation who haven't gotten enough relief from medication alone. It aims to see if isolating the superior vena cava along with the pulmonary veins is safe and effective.
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.
This trial compares different techniques for a second heart ablation procedure in people with atrial fibrillation (AFib) who have already had one ablation. It aims to find the best approach to stop AFib from coming back.
This study compares two extra ablation procedures done along with standard pulmonary vein isolation in people with persistent atrial fibrillation. Both aim to stop abnormal electrical signals that drive atrial fibrillation, and the study will see which approach is safer and more effective.
