Mitral Annular Calcification Score Determined by 3-D Transesophageal Echocardiography vs Cardiac Computed Tomography.

ABSTRACT:

Background

A cardiac computed tomography (CT)-based mitral annular calcification (MAC) scoring system systematically grades MAC severity, but its correlation with three-dimensional transesophageal echocardiography (3D-TEE) remains unclear.

Objectives

The authors aimed to compare MAC severity assessment by 3D-TEE vs CT and evaluate their associations with hemodynamic parameters indicative of mitral valve disease.

Methods

We analyzed patients with MAC enrolled in the MITRAL (Mitral Implantation of TRAnscathether vaLves) II trial (NCT04408430) across 13 centers undergoing transcatheter mitral valve replacement screening. Core laboratories assessed MAC severity using 3D-TEE and CT. Correlation and agreement were assessed via Spearman and intraclass correlation coefficient
