CAMERA-MRI II: Catheter Ablation versus Medical Rate Control in Atrial Fibrillation with Systolic Heart Failure and Myocardial Fibrosis - an MRI guided Multi-Centre Randomised Controlled Trial

心房颤动（AF）是一种不规则的心律，常见于心肌功能减弱的患者。如果通过导管消融术恢复心律，症状和心功能可能会改善。这项研究将评估这种手术是否能改善心房颤动患者的心脏功能，这些患者的心脏存在虚弱和疤痕。我们希望能更好地确定哪些患者最适合，并从这个过程中获得最大的好处。

Atrial fibrillation (AF) is an irregular heart rhythm commonly seen in patients with a weakened heart muscle. Symptoms and heart function may improve if the rhythm is restored through a catheter ablation procedure. This study will assess whether this procedure improves the function of the heart in those with AF where there is weakness and scarring of the heart. We hope to better determine which patients are best suited and will derive the most benefit from this procedure.
