SVC isolation for repeat AFib ablation
Part of Heart & circulation clinical trials.
This study tests if isolating the superior vena cava (a large vein in the chest) can help control AFib in people who have already had a prior ablation for paroxysmal (comes and goes) AFib and whose pulmonary veins are still blocked.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have atrial fibrillation that comes and goes (paroxysmal AFib).
- You have had one prior catheter ablation that only treated the pulmonary veins.
- At a recent procedure, the doctor confirmed that your pulmonary veins are still blocked (isolated).
- You do not have AFib that stays constantly (persistent AFib).
- Your first ablation did not treat any areas besides the pulmonary veins.
- You are not pregnant and can give written consent.

This study tests a new catheter that uses pulsed field energy to isolate the veins in your heart that trigger atrial fibrillation. The goal is to see how long the effects last, and you would need to have a repeat procedure about 2–3 months after the first one.
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 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 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 study compares two ways to treat persistent atrial fibrillation during a catheter ablation procedure. It tests whether adding isolation of the back wall of the left atrium or using alcohol to ablate a small vein near the heart can improve outcomes compared to standard pulmonary vein isolation alone.
This trial compares two types of repeat ablation for people whose persistent atrial fibrillation (AF) has come back after a prior procedure. It tests whether adding isolation of the back wall of the heart's left atrium to the standard vein isolation improves outcomes. If you have had up to two prior AF ablations and are willing to be followed, you may qualify.
