The REAL Registry is a large observational study tracking real-world outcomes in patients who receive catheter ablation—a minimally invasive procedure that uses heat or pulsed energy to correct dangerous heart rhythms. The study focuses on people with atrial fibrillation (irregular heartbeats that come and go, or persist for days to months) or ventricular arrhythmias (dangerous rhythms originating in the heart's lower chambers), and uses Biosense Webster ablation technologies including THERMOCOOL SMARTTOUCH, QDOT MICRO, and VARIPULSE catheters. Researchers want to understand how well this treatment works in everyday clinical practice and how safe it is over the long term.
Catheter ablation is an established treatment for heart rhythm problems, but doctors need real-world data on how these newer mapping and ablation technologies perform in actual patients over time. This registry will help answer important questions about the procedure's effectiveness, safety, and how well people do months and years after treatment.

If you enroll, you'll receive catheter ablation as planned by your doctor—the study does not change your treatment. You'll be asked to attend baseline appointments before the procedure and follow-up visits after ablation to check how you're doing, including assessments at 7 days, 30 days, and beyond the first 90 days. The study tracks whether your heart rhythm problems return, whether you experience any complications, and how well the procedure worked for you over time. Because this is a registry (not a randomized trial), your care follows standard practice at your hospital, and your participation simply means sharing your medical outcomes with the research team.
