Read our Atrial Fibrillation research guide →This is a registry study that follows patients with atrial fibrillation (an irregular heart rhythm) who undergo a procedure called pulmonary vein isolation using a newer device called the Heliostar radiofrequency balloon catheter. Researchers want to collect information about how well this newer balloon catheter works and how safe it is when used in real-world clinical practice across multiple hospitals.
Atrial fibrillation is a common heart rhythm problem that can lead to serious complications like stroke. While catheter ablation is an established treatment, this study aims to gather real-world safety and effectiveness data on a newer balloon catheter technology to better understand its benefits and risks compared to what we already know.

You would undergo the pulmonary vein isolation procedure using the Heliostar balloon catheter as your doctor has already planned. The study simply collects information about your procedure and follows your recovery and heart rhythm over time according to your hospital's standard care plan. Researchers will monitor you for any complications and track whether your heart rhythm remains stable after the procedure.
