Right Ventricular Myocardial Work by Echocardiography: A Scoping Review of Methodology, Validation, and Clinical Applications

Abstract

Echocardiographic assessment of right ventricular (RV) function remains challenging because conventional functional and deformation indices are strongly influenced by loading conditions. Right ventricular myocardial work (RVMW), derived by integrating myocardial deformation with ventricular pressure, has emerged as a potential framework for contextualizing RV mechanics according to afterload. However, its methodology, validation, clinical applications, and readiness for routine use have not been comprehensively mapped.
