Mitral Annular Function in Mitral Annular Calcification and Severe Mitral Regurgitation.

ABSTRACT:

Background

Longitudinal left ventricular (LV) shortening, or mitral atrioventricular plane displacement (AVPD), reflects mitral annular function.

Objectives

The authors sought to demonstrate the use of cardiac computed tomography (CCT) to measure mitral AVPD and assess its contribution to LV stroke volume (LVSV) in patients with mitral annular calcification (MAC), severe functional mitral regurgitation (FMR), and severe primary mitral regurgitation (PMR) without MAC.

Methods

We included 200 patients with circumferential MAC (age 79.6 ± 10 years), 50 with severe FMR (age 74 ± 8 years), 50 with severe PMR (age 83 ± 10 years), and 50 control subjects (age 41.6 ± 16 years) who underwent CCT (2016-2022). AVPD was measured in all patients. The volume of blood attributable t
