Example of a young woman with a bileaflet prolapse and a mitral annular disjunction (MAD). Longitudinal strain demonstrates the impact of MAD on left ventricular function. (A–C) MAD (double green arrow) in parasternal and apical long axis views. There is an atrialisation of a part of the left ventricle in regard of the posterior leaflet insertion. The sudden and excessive displacement of leaflets toward the left atrium in systole elicits an abnormal tension and stretch of chordae and papillary muscles. Not only the secondary chordae but also the chordae that are directly attached to the basal segments of the left ventricle. (D) In 3D-echo, the posterior leaflet prolapses totally in the left atrium in systole. The prolapse is less marked for the anterior leaflet in this example. (E) Mitral annulus disjunction can induce abnormal longitudinal deformation of left ventricular basal segments, associated with cardiac MRI to inferolateral basal myocardial wall fibrosis. 3D, three-dimensional.
