PAROXYSMAL ATRIAL FIBRILLATION

This study is testing a new medical device system designed to treat a common type of irregular heartbeat called atrial fibrillation (AFib). The procedure uses pulsed electrical fields to scar heart tissue and block faulty electrical signals. Researchers aim to see if this new sys…

This study is checking how safe and effective a heart procedure is over three years for people with a type of irregular heartbeat called paroxysmal atrial fibrillation. It will follow 250 patients who have tried medications that didn't work well enough. Researchers will track whe…

This study is testing a new approach during a heart procedure called catheter ablation to better treat a common irregular heartbeat (paroxysmal atrial fibrillation). Researchers want to see if using a special electrical stimulation test to guide where to apply the ablation can pr…

This study is testing new electrical waveforms delivered through the FARAPULSE system to treat atrial fibrillation, a common irregular heartbeat condition. Researchers will enroll 200 adults with either occasional or persistent atrial fibrillation to evaluate the safety and effec…

This study follows 200 patients with recurrent atrial fibrillation symptoms to see how well a freezing catheter procedure works over three years. The procedure freezes small areas of heart tissue to prevent irregular heartbeats, offering an alternative to medication. Researchers …

This study is testing the safety and effectiveness of a medical device that uses extreme cold (cryoablation) to treat a type of irregular heartbeat called paroxysmal atrial fibrillation. It is for people whose symptoms keep coming back despite taking medication. Doctors will use …

This study is testing whether adding a special ultrasound treatment to the kidneys during a repeat heart procedure helps prevent atrial fibrillation (AFib) from returning. It involves 250 adults with high blood pressure whose AFib has come back after a previous procedure. Partici…

This study is testing a recently approved pulsed field ablation system for treating atrial fibrillation in typical patients seen in regular medical practice. The procedure uses electrical pulses to create scar tissue in the heart to block irregular electrical signals. Researchers…

This study is testing a new, paddle-shaped catheter designed to create detailed maps of irregular heartbeats. Doctors will use it on 60 patients with conditions like atrial fibrillation or ventricular tachycardia to see if it's safe and works well. The goal is to see if this tool…

This study aims to learn more about how a new, small heart device called the Micra AV2 works in people with a history of a specific irregular heartbeat (paroxysmal atrial fibrillation). Researchers will observe 50 patients who are getting the device as part of their standard care…

This study follows 50 patients with intermittent atrial fibrillation who receive a standard catheter ablation procedure. Researchers will use exercise tests and heart imaging to measure how the heart's pumping function improves during physical activity after treatment. The goal i…

This is a small pilot study to see if it's practical to run a larger trial on how short-term exercise affects symptoms in people with atrial fibrillation (AF). Researchers will enroll 36 symptomatic men and women with AF. Participants will try a week of moderate exercise, a week …
