- Abstract
The article presents information about mitral annular disjunction (MAD), which is the abnormal insertion of the posterior leaflet of the mitral valve outside the area of the atrioventricular (AV) junction. Two phenotypes of MAD are mentioned: true disjunction, in which abnormal insertion can be observed in both diastole and systole, and pseudo disjunction, in which only the disjunction space can be seen in systole. It is emphasized that true disjunction is more common than previously thought and further research is needed to determine its clinical implications. Additionally, it is mentioned that annular disjunction in patients with prolapse is associated with larger annuli and more severe prolapses, which may explain the higher incidence of arrhythmic events in this group.
