Right ventricular (RV) size and function assessed by multimodality imaging are associated with outcomes in a variety of cardiovascular diseases. Understanding RV anatomy and physiology is essential ...in appreciating the strengths and weaknesses of current imaging methods and gives these measurements greater context. The adaptation of the right ventricle to different types and severity of stress, particularly over time, is specific to the cardiovascular disease process. Multimodality imaging parameters, which determine outcomes, reflect the ability to image the initial and longitudinal RV response to stress. This paper will review the standard and novel imaging methods for assessing RV function and the impact of these parameters on outcomes in specific disease states.

•Given the complex anatomy and physiology of the RV, quantitative measures of function using a multiparametric, multimodality approach are the best indicators of right heart function in specific disease states.•Imaging parameters that reflect longitudinal RV function, such as TAPSE, TDIs’, and FWS are particularly useful measures of RV function.•Novel imaging modalities and applications of artificial intelligence may further improve assessment of RV dysfunction.
