PAROXYSMAL ATRIAL FIBRILLATION

This study tests a procedure called pulsed field ablation (PFA) for people with early-stage atrial fibrillation (AFib) diagnosed within the last 3 years. The procedure uses a balloon to deliver energy that isolates the pulmonary veins, aiming to stop abnormal heart rhythms. Resea…

This study tests a catheter-based procedure called Varipulse to treat paroxysmal atrial fibrillation (irregular heartbeat that comes and goes). Researchers want to see how well it works long-term when combined with different types of sedation. About 300 adults aged 18-80 with sym…

This study tests a device called the Globe Pulsed Field System, which uses short bursts of electric energy to destroy tiny areas of heart tissue that cause abnormal rhythms in people with paroxysmal atrial fibrillation (a type of irregular heartbeat that comes and goes). The tria…

This study tests a new imaging and guidance system called VERAFEYE that creates a 3D model of the heart to help doctors navigate during catheter ablation for atrial fibrillation. About 50 adults with paroxysmal or persistent atrial fibrillation will have their standard ablation p…

This study tests a new device called the VERAFEYE System, which creates a 3D model of the heart to guide doctors during catheter ablation for paroxysmal atrial fibrillation (a type of irregular heartbeat). About 100 adults who are already scheduled for ablation will have the proc…

This study tests a new way to treat atrial fibrillation (AFib), a condition where the heart beats irregularly. Doctors will use pulsed field ablation (PFA) instead of heat or cold to create scars in the heart and block bad signals. They will also use a special 3D ultrasound syste…

This trial will enroll about 3,200 people with paroxysmal atrial fibrillation (AF) to see if using a smartwatch to continuously track AF burden can guide earlier and better treatment. Participants will be monitored with a wearable device, and if their AF burden is high, doctors w…

This study compares two common heart rate-lowering drugs, verapamil and metoprolol, in 436 adults with paroxysmal atrial fibrillation (AF). It also tests whether using a smartwatch for self-care can reduce hospital visits and improve symptoms. The goal is to find better ways to m…

This study compares two heart procedures for people with paroxysmal atrial fibrillation (AFib), a condition where the heart beats irregularly. One group gets standard ablation to isolate the pulmonary veins, while the other also gets ablation of the superior vena cava using pulse…

This study tests a new procedure called pulsed field ablation (PFA) using the FARAPULSE system to treat people with paroxysmal atrial fibrillation, a type of irregular heartbeat. Researchers will enroll 200 Chinese patients to see if the procedure can safely isolate the veins tha…

This trial investigates whether analyzing electrical signals from the heart during pulsed field ablation can tell doctors how well the catheter is touching tissue and whether the resulting scar will be permanent. About 60 people with paroxysmal atrial fibrillation will undergo th…

This study tests a new wearable system called M2VS that measures heart activity (ECG) and blood pressure continuously for 24 hours. Researchers want to see if it works as well as standard monitors like Holter ECG and ambulatory blood pressure monitors. The study involves 20 adult…

This study will compare five different pulsed field ablation systems used to treat atrial fibrillation (an irregular heartbeat). The goal is to see which system causes the fewest tiny clots (microemboli) that travel to the brain during the procedure. One hundred adults with atria…
