Mitral Annular Disjunction Assessed Using CMR Imaging: Insights From the UK Biobank Population Study.

ABSTRACT:

Background

Mitral annular disjunction is the atrial displacement of the mural mitral valve leaflet hinge point within the atrioventricular junction. Said to be associated with malignant ventricular arrhythmias and sudden death, its prevalence in the general population is not known.

Objectives

The purpose of this study was to assess the frequency of occurrence and extent of mitral annular disjunction in a large population cohort.

Methods

The authors assessed the cardiac magnetic resonance (CMR) images in 2,646 Caucasian subjects enrolled in the UK Biobank imaging study, measuring the length of disjunction at 4 points around the mitral annulus, assessing for presence of prolapse or billowing of the leaflets, and for curling motion of the inferolateral left ventricular w
