Read our Atrial Fibrillation research guide →This study is testing whether two types of heart imaging — a CT scan and an MRI scan — can help doctors predict which patients will benefit most from ablation, a procedure that treats an irregular heart rhythm called atrial fibrillation. The imaging looks at the structure and function of the left chamber of your heart, specifically focusing on fat and scar tissue that may affect how well the ablation procedure works.
Right now, doctors don't have a good way to predict ahead of time which patients will have the best results from ablation treatment. This study hopes to find imaging markers that can help select the right patients for this procedure and improve treatment success.

If you join this study, you will have a CT scan and an MRI scan of your heart before your scheduled ablation procedure. These imaging tests are designed to look at the structure and function of your heart's left chamber. You may also have follow-up imaging after your ablation treatment to see how the heart changes. The study involves about 130 patients total and is being conducted at hospitals in Paris.
