Redo ablation for recurrent atrial fibrillation with Sphere-9 catheter
Part of Heart & circulation clinical trials.
This trial tests a new catheter and system for people who have had one previous ablation for atrial fibrillation but still have symptoms. It aims to see if a repeat procedure can safely and effectively treat recurrent episodes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have had one previous ablation for atrial fibrillation within the last 3 years.
- You have had symptoms of atrial fibrillation, atrial flutter, or atrial tachycardia at least 3 months after that ablation.
- You have had at least one documented episode of these abnormal heart rhythms in the past year.
- You do not have a pacemaker, defibrillator, or other implanted heart device.
- You are on blood thinners for at least 3 weeks before the procedure.

This trial tests a new catheter-based treatment for paroxysmal atrial fibrillation (AF) — a type of irregular heartbeat that comes and goes. It uses a special balloon catheter to deliver energy to the heart to help restore a normal rhythm. This may be an option if medications haven't controlled your symptoms.
This trial tests a catheter ablation procedure for people with persistent atrial fibrillation (a type of irregular heartbeat that lasts more than 7 days but less than a year). It aims to see if the procedure is safe and effective for restoring a normal heart rhythm.
This trial compares two catheter ablation techniques for people with persistent atrial fibrillation (a type of irregular heartbeat that doesn't go away on its own). It will test whether a more extensive ablation (burning more heart tissue) works better than the standard procedure of isolating the pulmonary veins (the veins that bring blood from the lungs to the heart). If you have this condition and have had at least one episode in the past year, this study might help you find a more effective 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 trial tests a newer, possibly safer way to treat persistent atrial fibrillation using pulsed field ablation. It compares standard vein isolation alone to adding extra ablation spots to improve success.
This trial tests a new balloon catheter that uses pulsed electric fields to treat persistent atrial fibrillation, a type of irregular heartbeat that lasts more than 7 days. The treatment aims to restore normal heart rhythm and may be an option for people who have not had prior heart procedures.
