Artificial Intelligence Mapping and Ablation of Non-Pulmonary Vein Electrical Drivers of AF Study

This study is looking for adults aged 22 or older who have been diagnosed with a specific type of Atrial Fibrillation (AF). This includes AF that is 'persistent' (meaning it doesn't go away on its own but hasn't lasted for a very long time) or 'recurrent' (meaning it comes and goes). You must be considered suitable for a heart ablation procedure by your doctor, and have had recent ECG recordings of your heart activity.

However, you won't be able to join if you have a different type of AF, especially if your AF has been persistent for a year or more. You also can't take part if you're pregnant, or if the quality of your heart's electrical recordings (ECGs) isn't clear enough for the study. If you're already involved in another clinical trial with a new medication or device, or if your doctor thinks taking part might put your health at risk, you also won't be able to join.

If you decide to take part, you'll have an initial assessment. Then, you'll be randomly put into one of two groups: either you'll receive the standard PVI procedure, or you'll have the PVI procedure guided by the vMap® system. The actual heart procedure will be just like a normal PVI, but for one group, the vMap® tool will be used to help plan it. You'll need to attend follow-up appointments after your procedure so the study doctors can see how you're doing. The total length of your participation, including follow-up, will be explained to you in detail.
