Статья представляет собой обзор литературы, посвященный значению эхокардиографии в выявлении и оценке митральной аннулярной дизъюнкции – специфической анатомической аномалии, характеризующейся отчетливым разделением между митральным кольцом и стенкой левого предсердия, с одной стороны, и базальной частью задне-бокового сегмента миокарда левого желудочка – с другой. Митральная аннулярная дизъюнкция является нередким компонентом аритмических пролапсов митрального клапана с фиброзом левого желудочка. Приводятся данные о связи митральной аннулярной дизъюнкции с желудочковыми аритмиями и у пациентов без пролапса митрального клапана. Наряду с эхокардиографией приводится значение других неинвазивных методов визуализации в диагностике митральной аннулярной дизъюнкции.

The article is a review of the literature on the importance of echocardiography in the detection and evaluation of the mitral annular disjunction, a specific anatomical anomaly characterized by a distinct separation between the mitral annulus and the wall of the left atrium on the one hand and the basal part of the posterolateral segment of the left ventricular myocardium on the other. Mitral annular disjunction is a common component of arrhythmic mitral valve prolapse with left ventricular fibrosis. Data are presented on the relationship between mitral annular disjunction and ventricular arrhythmias in patients without mitral valve prolapse. Along with echocardiography, the importance of other non-invasive imaging methods in the diagnosis of mitral annular disjunction is given.
