Freezing treatment as first choice for persistent atrial fibrillation
Part of Heart & circulation clinical trials.
This trial tests whether using freezing (cryoablation) as the first treatment for persistent atrial fibrillation is better than starting with anti-arrhythmic drugs. The goal is to restore a normal heart rhythm and reduce symptoms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have persistent atrial fibrillation (a heart rhythm problem) that has lasted between 7 days and 12 months, or it started as paroxysmal AF (comes and goes) and then became persistent.
- You have had at least 2 episodes of AF in the last 2 years, with the most recent one within the last 6 months.
- You have not had previous ablation (a procedure to destroy the tissue causing the abnormal rhythm) or heart surgery for AF.
- You do not have severe heart failure, severely enlarged heart chamber, or severely reduced heart pumping function.
- You do not have serious lung disease, serious kidney disease, or significant valve disease needing treatment.

This study tests whether doing a second ablation (a procedure that uses heat or cold to destroy tiny areas of heart tissue that cause irregular beats) can help people with persistent atrial fibrillation (a continuous irregular heartbeat) that has come back after a first ablation. It aims to see if this repeat procedure safely reduces symptoms and improves heart rhythm.
This trial compares two ways to treat persistent atrial fibrillation (an irregular heartbeat that lasts for months or years). One method uses pulsed field energy and the other uses radiofrequency heat to fix the heart's electrical signals. The goal is to see which method is safer and more effective for patients having their first ablation procedure.
This trial tests a new procedure that uses pulsed electric fields to treat persistent atrial fibrillation, a type of irregular heartbeat. The goal is to see if this approach is safe and effective in restoring a normal heart rhythm.
This study tests a new way to treat persistent atrial fibrillation (a type of irregular heartbeat) during your first catheter ablation procedure. The goal is to see if this approach offers better results than the usual care.
This trial tests a new type of ablation (pulsed-field) to treat persistent atrial fibrillation (AFib) that lasts more than 7 days. You may qualify if you have symptoms and haven't had other heart ablation procedures except for one specific type.
This trial tests a newer type of energy (pulsed field ablation) against the standard heat-based method (radiofrequency) for people who have already had one ablation and now have atrial fibrillation again. The goal is to see which works better for keeping your heart in a normal rhythm.
