PAROXYSMAL ATRIAL FIBRILLATION

This study tests a new approach to treat paroxysmal atrial fibrillation (a common heart rhythm problem) using a technique called burst stimulation to guide extra ablation spots. About 240 adults aged 18-80 who are having their first catheter ablation will be randomly assigned to …

This study tests whether adding a kidney nerve treatment (renal denervation) to a repeat heart ablation procedure can better prevent atrial fibrillation from coming back. It involves 250 adults with high blood pressure who need a second ablation. Participants are randomly assigne…

This study follows 250 people with a type of irregular heartbeat (paroxysmal atrial fibrillation) that doesn't get better with medication. Researchers want to see if a special heart ablation system is safe and works well over 3 years. The goal is to keep the heart in normal rhyth…

This study compares two heart ablation techniques for people with paroxysmal atrial fibrillation (AFib) that came back after a prior successful vein isolation. One group gets standard isolation of the superior vena cava (SVC), while the other gets that plus ethanol injection into…

This study tests new energy waveforms from the FARAPULSE system to treat atrial fibrillation, a common heart rhythm problem. About 200 adults with either short-term or persistent AFib will receive the procedure. The goal is to see if the new waveforms can safely and effectively i…

This study follows 200 people with a type of irregular heartbeat called paroxysmal atrial fibrillation. They receive a standard procedure that uses a freezing balloon to isolate the veins that trigger the abnormal rhythm. The goal is to see how well the treatment prevents the hea…

This study looks at how the heart's left atrium works during exercise after a procedure called catheter ablation for paroxysmal atrial fibrillation (a type of irregular heartbeat). Researchers will use special MRI scans taken while people exercise to measure changes in heart func…

This study looks at whether it's possible to run a larger trial comparing how different types of exercise (moderate or high intensity) affect symptoms of atrial fibrillation (AFib) compared to a week of rest. About 36 adults with AFib who have symptoms will try each approach. The…

This study is testing a new paddle-shaped catheter designed to map abnormal heart rhythms (arrhythmias) in the upper and lower chambers of the heart. About 60 people with conditions like atrial fibrillation or ventricular tachycardia will take part. The main goal is to check if t…

This study is a registry that will track the safety and success of a procedure called pulsed field ablation (PFA) for treating atrial fibrillation (an irregular heartbeat) in people from racial and ethnic minority groups. About 275 participants will be followed for one year to se…

This study aims to learn more about how a new, small heart device called the Micra AV2 works in people with a history of a specific irregular heartbeat (paroxysmal atrial fibrillation). Researchers will observe 50 patients who are getting the device as part of their standard care…
