Inter-technique agreement of left atrial and ventricular deformation analysis: a comparison between transthoracic echocardiography and cardiovascular magnetic resonance imaging.

ABSTRACT:

Background

Myocardial strain measurements are increasingly used in research and clinical practice. However, there are limited data on inter-modality agreement and reproducibility. We aimed to investigate the inter-technique agreement of transthoracic echocardiography (TTE) and cardiovascular magnetic resonance (CMR) imaging derived left atrial (LA) and left ventricular (LV) deformation parameters.

Methods

Subjects with or without cardiovascular disease were prospectively recruited and had TTE and CMR on the same day. Ten subjects with type 2 diabetes (T2D) had both scans repeated within two weeks for test-retest reproducibility assessment. Myocardial deformation analyses were undertaken including LA strain (LAS) corresponding to LA reservoir, conduit and booster pump phases,
