Evaluation of left atrial longitudinal function in patients with hypertrophic cardiomyopathy: a tissue Doppler imaging and two-dimensional strain study

Abstract

Left atrial longitudinal function is reduced in HCM compared to non-HCM LVH and healthy controls. In addition, 2D atrial strain has an additive value in differentiating HCM from non-HCM LVH and it is more reproducible and less time consuming than TDI strain.
