Mitral annular disjunction and mitral valve prolapse: echocardiographic-MRI insights into cardiac function
Abstract
BACKGROUND: Mitral annular disjunction (MAD) may accompany mitral valve prolapse (MVP) and is linked to ventricular arrhythmias. Its impact on global cardiac performance (specifically cardiac index (CI) and output (CO)), remains incompletely defined. Cardiac MRI (CMR) allows precise measurement of MAD, assessment of mitral annular dynamics, and detection of myocardial fibrosis via late gadolinium enhancement (LGE). We investigated both CMR and TTE metrics in patients with varying degrees of MAD compared to MVP-only. METHODS AND RESULTS: Fifty-six patients who underwent CMR and TTE (mean age 61, 33 female) were divided into MAD ≥2 mm and MVP (the "MAD + MVP" group, n = 41) or MVP-only (n = 15). MAD was classified as
