ATRIAL FIBRILLATION PAROXYSMAL

This study tests a new device called the CellFX nsPFA catheter, which uses short electrical pulses instead of heat to treat paroxysmal atrial fibrillation (a type of irregular heartbeat). The goal is to see if it is safe and effective at restoring normal rhythm in 215 adults who …

This study tests a new device called the CellFX Nano-PFA 360 catheter, which uses very short electrical pulses to treat atrial fibrillation (an irregular heartbeat). About 60 adults aged 18 to 75 with paroxysmal atrial fibrillation will receive this procedure. The goal is to see …

This early study tests a new balloon device that uses pulsed electric fields to treat atrial fibrillation, a common heart rhythm disorder. 75 people with short-duration AF who haven't had prior ablation will receive the procedure and be followed for one year. The goal is to see i…

This study looks at whether screening for and treating sleep apnea can reduce the burden of atrial fibrillation (AFib) in patients who are candidates for heart ablation. Fifty adults with paroxysmal or persistent AFib that hasn't responded to medication will be screened for sleep…

This study tests a new approach for treating paroxysmal atrial fibrillation (a type of irregular heartbeat). It combines two procedures: pulsed-field ablation to isolate the pulmonary veins, plus targeted thermal ablation of a nerve cluster near the heart. The goal is to see if a…

This study compares two types of catheter ablation for people with paroxysmal atrial fibrillation (a type of irregular heartbeat). The goal is to see if a newer method called pulse field ablation preserves heart muscle function better than the standard cryoablation. Eighty adults…

This study tests whether a smartwatch and text message system can encourage people with paroxysmal atrial fibrillation (a type of irregular heartbeat) to be more physically active. The trial has two phases: first, a small group will help design the messages and test the smartwatc…

This study tests whether a 12-week digital MediYoga program—combining deep breathing, gentle yoga, and meditation—can improve quality of life, lower blood pressure, and reduce heart rate in 456 adults with paroxysmal atrial fibrillation. Participants use a smartphone app and get …

This study looks at whether avoiding alcohol reduces the chance of an atrial fibrillation (AFib) episode in people with paroxysmal AFib. One hundred participants will be randomly assigned each day to either avoid or be allowed to drink alcohol. They will wear heart monitors, fitn…

This study looks at how two different catheters used to treat atrial fibrillation (a type of irregular heartbeat) affect the temperature of the esophagus (the tube connecting the mouth to the stomach) and the risk of injury to it. About 30 adults with paroxysmal atrial fibrillati…
