Prevalence, Characteristics, and Arrhythmogenic Substrate of Mitral Annular Disjunction Assessed by Cardiac Magnetic Resonance Imaging in Patients With Apparently Idiopathic Ventricular Arrhythmia

Prevalence, Characteristics, and Arrhythmogenic Substrate of Mitral Annular Disjunction Assessed by Cardiac Magnetic Resonance Imaging in Patients With Apparently Idiopathic Ventricular Arrhythmia

ABSTRACT Background Mitral annular disjunction (MAD) is linked to an increased risk of sudden cardiac death, but its association with ventricular arrhythmias (VAs) in Japanese patients is unclear. Methods We retrospectively analyzed 129 Japanese patients with VAs and no overt structural heart diseas...
