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.
