MVP has two distinct anatomical subtypes: Barlow's disease and fibroelastic deficiency; each reflects different underlying structural and pathological processes. While most individuals generally remain asymptomatic with subclinical regurgitation, some develop significant mitral regurgitation followed by heart failure. A malignant form of MVP, marked by bileaflet prolapse, mitral annular disjunction (MAD), and myocardial fibrosis, is increasingly recognized as a substrate for ventricular arrhythmias and sudden cardiac death. In addition to transthoracic/transesophageal echocardiography, cardiac magnetic resonance is expected to contribute to risk stratification, particularly in identifying high-risk features such as MAD and fibrosis. As diagnostic capabilities continue to advance, integrating phenotypic, imaging, and electrophysiological insights will be key to optimizing outcomes in patients with MVP.
