PAROXYSMAL ATRIAL FIBRILLATION

This study looks at people with paroxysmal atrial fibrillation (a type of irregular heartbeat) who need a second procedure because their first treatment didn't last. It compares two approaches: isolating a vein in the heart (SVC) alone, or adding an alcohol injection into another…

This study tests new energy waveforms from the FARAPULSE system to treat atrial fibrillation, a common heart rhythm problem. About 200 adults with either occasional or persistent AFib will receive a minimally invasive procedure to isolate faulty electrical signals in the heart. T…

This study follows 200 people with a type of irregular heartbeat called paroxysmal atrial fibrillation. They will receive a procedure using a special catheter that freezes heart tissue to restore normal rhythm. The goal is to see how many remain free from heart rhythm problems fo…

This study looks at how safe and effective the QDOT MICRO system is over three years for people with a type of irregular heartbeat called paroxysmal atrial fibrillation that doesn't get better with medication. About 250 adults who are candidates for a heart ablation procedure wil…

This study tests a new, faster method to treat paroxysmal atrial fibrillation (a type of irregular heartbeat). Doctors will use a very high power, short duration energy to isolate the veins in the heart. The goal is to see if this approach reduces procedure time while still being…

This study tests whether adding a burst stimulation-guided ablation to the standard pulmonary vein isolation procedure can lower the chance of atrial fibrillation coming back. About 240 adults with paroxysmal AFib who are having their first catheter ablation will be randomly assi…

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 275 patients who are racial or ethnic minorities. The procedure uses FDA-approved catheters to correct th…

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 looks at how well the Micra AV2 pacemaker tracks the heart's natural rhythm and detects hidden atrial fibrillation (an irregular heartbeat) in 50 people with a history of the condition. Participants will have their pacemaker checked regularly and may wear a special mon…

This study looks at whether a week of exercise (moderate or high intensity) changes symptoms of atrial fibrillation compared to a week of rest. It includes 36 adults aged 40+ with paroxysmal or persistent AF who have had symptoms recently. The main goal is to see if a larger stud…

This study follows 50 adults with paroxysmal atrial fibrillation (AF) who are scheduled for catheter ablation. Researchers use exercise cardiac MRI before and 5-6 months after the procedure to measure how well the heart's left atrium works during exercise. The goal is to understa…

This study is testing a new, paddle-shaped catheter designed to map abnormal heart rhythms (arrhythmias) in people with conditions like atrial fibrillation or ventricular tachycardia. About 60 participants will undergo a standard heart-mapping procedure using this investigational…
