Insights into the relationship between mitral annular dimensions, derived sphincter-like features and systolic longitudinal excursion of the mitral annular plane in healthy adults from the MAGYAR-Healthy Study
Year: 2025
Type: article
Abstract: Background: The mitral annulus (MA) is a fibrous ring with a three-dimensional (3D) movement during the cardiac cycle having an up-and-town longitudinal motion and a sphincter-like narrowing-dilating pattern respecting the cardiac cycle. In the clinical practice, the MA plane systolic excursion (MAPSE), a feature of MA longitudinal function, can be assessed by the simple and widely used M-mode echocardiography (MME), while changes of MA dimensions and derived functional properties can be accurately measured by 3D speckle-tracking echocardiography (3DSTE) at the same time. The aim of the present retrospective cohort study was to evaluate the associations between MME-derived MAPSE and 3DSTE-derived MA dimensions in healthy adults for better understanding their physiologic relationship. Methods: ) were used to create the subgroups of subjects with less than mean - SD, mean and larger than mean + SD. Results: . 14.5±3.7 mm, P=ns for all). Conclusions: MME-derived MAPSE and 3DSTE-derived MA dimensions and derived functional 'sphincter-like' properties are not associated in healthy adults.
