Article Synopsis
- Current guidelines don't recommend assessing right atrial volume routinely due to insufficient standardized data, but a new method called three-dimensional wall-motion tracking (3D-WMT) could change that.
- This study aimed to establish reference values for right atrial volume using both two-dimensional echocardiography (2D-echo) and 3D-WMT in a healthy adult population while evaluating the consistency of these methods.
- Results showed that while indexed volumes from 2D-echo and 3D-WMT were not strongly correlated, 3D-WMT provided better intra- and interobserver agreement, suggesting it could be a reliable method for measuring right atrial volume.
The echocardiographic technology known as three-dimensional wall motion tracking offers three-dimensional images of the myocardium and provides multiple measures of deformation, one of which is known as "area strain" (AS), which combines left ventricular longitudinal and circumferential deformations. Our aim was to describe the normal maximum systolic reference AS value in a sample of healthy subjects. Sixty consecutive subjects without known cardiovascular risk factors or diseases were enrolled, and left ventricular AS was measured.
