Abstract

The management in the patients with atrial fibrillation and dilated cardiomyopathy

Author(s): Yoon-Kee Siow, Chin-Yu Lin

Atrial Fibrillation (AF) not only maintains itself but also becomes closely linked with Left Ventricular (LV) dysfunction, creating a complex clinical picture for clinicians. Furthermore, Dilated Cardiomyopathy (DCM), marked by LV dysfunction and chamber dilation, adds another layer of complexity to patient management. The coexistence of AF and DCM poses significant challenges, requiring a nuanced approach to treatment. The recent consensus update has elevated catheter ablation to a Class I recommendation for treating patients with AF and Heart Failure (HF), affirming its effectiveness. However, the literature often overlooks patients specifically with DCM, revealing a notable gap and underscoring the critical need for tailored treatment strategies for this subgroup. This review aims to clarify the terms and pathophysiology related to AF and DCM, exploring tailored treatment options for patients dealing with both the conditions. By covering medical therapy, catheter ablation, device implantation, and novel mechanical net therapy, this comprehensive review seeks to offer valuable insights into managing this unique subset of AF patients effectively.
