Read our Atrial Fibrillation research guide →Atrial fibrillation is an irregular heartbeat that can lead to serious complications. Doctors treating this condition often use a procedure called catheter ablation, which involves creating small scars in the heart to restore normal rhythm. This study compares two different ways of detecting and mapping these scars — an MRI scan and an electrical mapping procedure — to see if they give consistent results and help predict which patients will have the best long-term outcomes.
Right now, doctors use two different techniques to find scarring in the heart before and after treating atrial fibrillation, but it's not clear if these techniques are detecting the same areas. Understanding how well these methods match up could help doctors better predict who will benefit most from treatment and reduce the chance of the irregular heartbeat coming back.

If you join this study, you will have an MRI scan of your heart before your planned ablation procedure, and doctors will perform an electrical mapping of your heart during the procedure itself. Your heart's scarring will be assessed using both methods so researchers can compare the results. You may be followed up afterward to see how well the procedure worked and whether your irregular heartbeat returns.
