Objectives The purpose of this study was to use speckle tracking analysis to evaluate the size, shape, and function of the atrial chambers in normal fetuses and develop a z-score calculator that can be used in future studies in fetuses at risk for ca

One of the problems for the clinician who desires to measure the interventricular septum (IVS) in a high-risk fetus is to know where to make the measurement. The purpose of this study was to use speckle-tracking analysis to measure the IVS area, 24-s

BACKGROUND: Atrial function has a close interdependence with ventricular function and plays a central role in maintaining optimal cardiac function. There are two well-defined timing methods used to determine the start point. The aim of this prospecti

Background Right ventricular (RV) volumetric and functional assessments are both crucial for the management of patients with hypoplastic left heart syndrome (HLHS). 3-dimensional echocardiography (3DE) for volume measurements and 2D speckle-tracking

Objectives To measure, using speckle-tracking technology, the fractional area change (FAC) of the right and left ventricles in normal fetal hearts between 20 and 40 weeks of gestation. Methods The four-chamber view of the fetal heart was obtained in

OBJECTIVE Annular plane systolic excursion (APSE) has been evaluated for the right (RV) and left (LV) ventricles using M-mode echocardiography. This study examined APSE using 2-dimensional speckle tracking (2DST) of the lateral and septal annuli of t

OBJECTIVE Because of parallel circulation in the fetus and the differential effect that various disease states may have on the shape of the right and left ventricles, this study was conducted to evaluate the sphericity index (SI) of 24 transverse seg

Introduction The purpose of this study was to simultaneously measure with speckle tracking software (STS) the end-diastolic ventricular area (A), basal transverse width (BW), mid-chamber transverse width, (MW) and the basal-apical length (BAL) in nor
