New heart-ablation method for long-lasting arrhythmias
Part of Heart & circulation clinical trials.
This study tests a new way to destroy the tissue causing dangerous heart rhythms using a detailed model of how the heart's electrical signals spread. It may be an option for people with long-lasting atrial fibrillation or hard-to-control ventricular arrhythmias who are already scheduled for a standard ablation procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a type of irregular heart rhythm called persistent atrial fibrillation (AFib) that has lasted for more than 6 months, and your doctor has decided you need a procedure to fix it (AF ablation).
- OR you have a different dangerous heart rhythm called ventricular fibrillation (VF) or ventricular tachycardia (VT) that hasn’t been well controlled with standard medications.
- You are willing and able to have a heart monitor (implantable Holter or defibrillator) that your doctors can check remotely after the procedure.
- You do NOT have an overactive thyroid, a severe infection, or other major medical condition causing your heart rhythm problem.
- You do NOT have a blood clot in your heart or other reason that makes heart catheterization unsafe.

This study compares a newer, faster type of ablation (high-power short-duration) with the standard approach for treating atrial fibrillation. The goal is to see which method is safer and more effective at restoring a normal heart rhythm.
This study tests a new combination treatment approach for people with long-standing persistent atrial fibrillation (a type of irregular heartbeat that lasts for years). It aims to see if this approach can help improve symptoms and restore a more normal heart rhythm.
This study compares two procedures to treat persistent atrial fibrillation (an irregular heartbeat that lasts more than a week). It looks at whether a newer method (pulsed-field ablation) works better than the standard method (radiofrequency ablation), both combined with a chemical injection to improve treatment success.
This trial tests a new type of heart procedure called pulsed field ablation for people with persistent atrial fibrillation (a long-lasting irregular heartbeat). It compares three different ways to use this ablation to try to restore a normal heart rhythm and reduce symptoms.
This study compares two types of ablation (a procedure that uses energy to fix irregular heartbeats) for people with persistent atrial fibrillation. It tests whether adding extra treatment to the back of the heart's left upper chamber helps improve outcomes compared to standard treatment alone.
This trial tests whether using a special heart-mapping device during ablation (a procedure to fix irregular heartbeats) can improve outcomes for people with persistent atrial fibrillation and an enlarged left heart chamber.
