The complex geometry and structure of the right ventricular (RV) cavity make the assessment of RV function and volumes by 2-dimensional (2D) echocardiography arduous. Highly trabeculated endocardial border and bellows-like contractile pattern are not explicitly imaged by 2D echocardiography.1,2 Furthermore, the retrosternal position of the right ventricle hinders its visualization, and minimal changes in the angle of insonification affect RV chamber measurement and thereby, reproducibility.

Parameters of RV function and volume derived from 2D echocardiography (tricuspid annular plane systolic excursion, RV to left ventricular diameter ratio, and fractional area change) do not reliably predict the risk of RV failure during mechanical circulatory support with left ventricular assist device.3,4 Similarly, 2D assessment of RV function and volume in pulmonary hypertension has been challenging. The etiology and hemodynamic classification (pre- versus postcapillary) of pulmonary hypertension are important determinants of the RV remodeling …
