Quantitative evaluation of longitudinal strain in layer-specific myocardium during normal pregnancy in China

Background The myocardial wall of the left ventricle is a complex, multilayered structure and is not homogenous. The aim of this study was to determine longitudinal strain (LS) in the three myocardial layers in normal pregnant women according to gestation proceedings. Methods The advanced two-dimensional speckle tracking echocardiography (2D STE) was performed on 62 women during...

Structural and functional changes in maternal left ventricle during pregnancy: a three-dimensional speckle-tracking echocardiography study

Background Pregnancy represents a physiological adaptation to the transient load changes of maternal heart. This study aimed to investigate maternal left ventricle (LV) performance during normal pregnancy by three-dimensional speckle-tracking echocardiography (3D STE) parameters considering LV loading and shape. Methods Sequential two-dimensional echocardiography (2DE) and 3D STE...
