New catheter for atrial fibrillation using nanosecond pulses
Part of Heart & circulation clinical trials.
This trial tests a new catheter that uses very short electrical pulses to treat atrial fibrillation (a type of irregular heartbeat). It may help people whose AF symptoms continue despite medication.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old.
- You have been diagnosed with paroxysmal atrial fibrillation (AF that comes and goes) and have had at least one episode in the past year.
- You have tried at least one heart rhythm medication (like a beta blocker or calcium channel blocker) and it didn't work well or caused side effects.
- Your left atrium (upper heart chamber) is not too large (5.5 cm or less on imaging) and your heart pumps at least 40% of blood per beat.
- You have not had a prior heart ablation or any implanted heart device like a pacemaker or ICD.
- You are not on amiodarone (a strong heart rhythm drug) in the last 3 months, and you don't have other serious health issues like active cancer, recent stroke, or kidney failure.

This trial tests a new type of heart procedure that uses gentle electrical pulses to fix abnormal signals in the upper chambers of the heart for people with a specific type of atrial fibrillation that comes and goes on its own. It may be an option if your AFib episodes stop within 7 days and medications haven't helped enough.
This trial tests a new treatment that uses two types of energy (pulsed field and radiofrequency) to fix the heart's electrical signals in people with paroxysmal atrial fibrillation (AFib that comes and goes). It aims to be more effective and safer than standard ablation alone.
This trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.
This study tests a new catheter system, called Varipulse, to see if it's safe and effective for treating atrial fibrillation (AF), a heart rhythm problem. People with short-lasting AF who haven't been helped by medication may be able to join.
This trial tests a new way to deliver energy (FARAPULSE PFA system) to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to see if these new waveforms can safely and effectively stop AF symptoms and improve quality of life.
This trial tests a new catheter and mapping system designed to treat paroxysmal atrial fibrillation (AF), which is a type of irregular heartbeat that comes and goes. If you have this condition, the study aims to see how well the new system works with a minimally invasive procedure.
