Test of a heart procedure during atrial fibrillation ablation

This trial tests three different ways of delivering radiofrequency energy using a specific catheter (QDOT) during a first-time procedure to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to find which method works best for patients with recent or short-lasting AF episodes.

This study tests advanced technology to improve how atrial fibrillation (AFib) is treated with a heart ablation procedure. It may help patients who are already advised to have AFib ablation by seeing how well the approach works in real clinical practice.

This trial tests whether an early procedure (catheter ablation) for atrial fibrillation (AF) can prevent strokes in people with a high risk of stroke. The goal is to see if this treatment is safer and more effective than standard care for patients with other health conditions.

This trial is studying a way to improve the entire process of catheter ablation for atrial fibrillation. It may help people who are having this procedure for the first time and have a normal-sized left atrium and good heart function.

This trial tests a new catheter system to treat atrial fibrillation (AF) by creating small scars in the heart to block faulty signals. It may help people with symptoms that continue despite medication and who are scheduled for a standard ablation procedure.

This trial studies whether CT scans and heart MRI scans (done around the time of atrial fibrillation ablation) can help care planning and results. It may help your team better understand your heart before and after the procedure.
