Atrial fibrillation (AF) is associated with clinical deterioration, stroke and disability in patients with hypertrophic cardiomyopathy (HCM). Therefore, the objective of this study was to evaluated cardiac magnetic resonance (CMR)-derived determinants for the occurrence of AF in patients with HCM. | Right ventricular and right atrial involvement can predict atrial fibrillation in patients with hypertrophic cardiomyopathy
