Atrial Fibrillation Ablation in Patients with Arrhythmia-Induced Cardiomyopathy: A Prospective Multicentre Study

Abstract

In the subset of patients referred for AF ablation, the development of AiCM was associated with persistent AF and CKD. Biomarker analysis was not different between groups nor predicted recurrence. Patients with AiCM benefited from ablation, with a significant improvement in left ventricular ejection fraction and similar AF recurrence rates to those without AiCM.
