In 1632, Galileo Galilei wrote in his Dialogo Sopra I Due Sistemi Massimi del Mondo (Dialogue Concerning the Two Chief World Systems), “All truths are easy to understand once they are discovered; the point is to discover them.” This quote by one of the world’s most famous scientists states that some truths need to be discovered before they can be widely accepted. In this issue of JAMA Cardiology, Nochioka et al1 sought to study the prognostic significance of a variety of right ventricular (RV) parameters, including 3-dimensional (3-D) echocardiographic assessment of the right ventricle in an elderly, population-based cohort. The authors found an association between RV function assessed by 3-D imaging and heart failure (HF) outcomes in this population. The results of this study underscore the importance of including 3-D measurements in the comprehensive assessment of the right ventricle in the echocardiography laboratory.
