This study is testing a new device called the VARIPULSE catheter system to treat persistent atrial fibrillation, a type of irregular heartbeat. The device uses pulsed field ablation to isolate specific heart veins and may be combined with a procedure to close off a heart pouch to…

This study tests a new system (VARIPULSE catheter and TRUPULSE generator) with updated software for treating persistent atrial fibrillation, a long-lasting irregular heartbeat. About 50 adults aged 18-75 who have not responded to medication will undergo a heart ablation procedure…

This study is checking the long-term safety and effectiveness of the VARIPULSE catheter, a device already approved by the FDA, for treating people with a type of irregular heartbeat called paroxysmal atrial fibrillation. About 276 participants who have symptoms and haven't respon…

This study tests a new catheter called VARIPULSE against an already approved one, FARAWAVE, for people with persistent atrial fibrillation (a long-lasting irregular heartbeat). About 466 participants will receive one of the two treatments to see which is safer and better at resto…

This study is testing a new system (VARIPULSE catheter and TRUPULSE generator) with updated software to treat atrial fibrillation, a condition where the heart beats irregularly. The goal is to see how well the system works in a real-world setting, measuring procedure times and sa…

This study is testing a new device that uses pulsed electric fields to treat paroxysmal atrial fibrillation, a condition where the heart beats irregularly. The procedure aims to isolate the pulmonary veins to restore normal rhythm. Researchers will enroll 440 people who have not …

This observational study will follow 8,000 people with irregular heartbeats (arrhythmias) who are scheduled for a standard catheter ablation procedure using Biosense Webster devices. Researchers will track safety issues and how well the procedure works in everyday hospital practi…

This study is testing a new paddle-shaped catheter designed to map the heart's electrical signals in people with various heart rhythm disorders like atrial fibrillation and ventricular tachycardia. The device has many sensors to create a detailed map of the heart's chambers. The …
