Mitral Annular Disjunction: A Scoping Review
Cardiology in Review, 2023Mitral annular disjunction (MAD) is the atrial displacement of the mitral valve (MV) hinge point, especially along the posterior mitral leaflet, which leads to inhomogeneous blood flow into the left ventricle, causing chronic fibrotic changes, malignant arrhythmias, and even sudden cardiac arrest. Some studies suggest that MAD is a part of normal heart

Imaging Considerations and Clinical Implications of Mitral Annular Disjunction
Circulation: Cardiovascular Imaging, 2022Mitral annular disjunction is increasingly recognized as an important anatomic feature of mitral valve disease. The presence of mitral annular disjunction, defined as separation between the left atrial wall at the point of mitral valve insertion and the left ventricular free wall, has been associated with increased degeneration of the mitral valve and ...

Morphology of Mitral Annular Disjunction in Mitral Valve Prolapse
Journal of the American Society of Echocardiography, 2022Mitral annular disjunction (MAD) is an abnormal insertion of the hinge line of the posterior mitral leaflet on the atrial wall: the mitral annulus shows a separation or "disjunction" between the leaflet-atrial wall junction and the crest of the left ventricle myocardium.

Mitral annular disjunction: A systematic review of the literature
Echocardiography, 2019AbstractBackgroundMitral annular disjunction (MAD) is a structural abnormality where there is a separation between the mitral valve annulus and the left atrial wall which is not well understood.MethodsWe conducted a systematic review to evaluate the prevalence of MAD, factors associated with MAD and clinical outcomes among patients with MAD.ResultsA ...

In patients with bileaflet mitral valve prolapse (MVP), mitral annular disjunction (MAD) is associated with increased risk of sudden cardiac death via incompletely understood mechanisms.This study assessed the substrate for ventricular arrhythmias in patients with bileaflet MVP and MAD as well as outcomes of catheter ablation with an emphasis on ...

Mitral Annular Disjunction: Review of an Increasingly Recognized Mitral Valve Entity
Radiology: Cardiothoracic Imaging, 2023Mitral annular disjunction (MAD) refers to atrial displacement of the hinge point of the mitral valve annulus from the ventricular myocardium. MAD leads to paradoxical expansion of the annulus in systole and may often be associated with mitral valve prolapse (MVP), leaflet degeneration, myocardial and papillary muscle fibrosis, and, potentially ...

Improving the imaging diagnosis of mitral annular disjunction
Heart, 2020Mitral annular disjunction (MAD) was described 30 years ago, originally by Bharati et al , reporting the sudden cardiac death of a 45-year-old man with a history of palpitations and with mitral valve prolapse (MVP).1 MAD is defined as the atrial displacement of the hinge point of the mitral valve from the ventricular myocardium.

Multimodality imaging assessment of mitral annular disjunction in mitral valve prolapse
Heart, 2020Objective Mitral annular disjunction (MAD) is an abnormality linked to mitral valve prolapse (MVP), possibly associated with malignant ventricular arrhythmias.
