PAROXYSMAL ATRIAL FIBRILLATION

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 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 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 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 study will test whether an artificial intelligence (AI) program can accurately detect atrial fibrillation (AF) using data from consumer smartwatches. Researchers will enroll 40 adults with AF who will wear a smartwatch while their heart rhythm is also monitored with standard…

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…

This study tests a new software module that analyzes heart signals during a procedure called pulsed field ablation, used to treat atrial fibrillation. The goal is to see if the software can accurately tell doctors when the targeted heart veins are fully isolated. One hundred adul…
