Multimodality Imaging of Right Heart Function JACC Scientific Statement

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.

Automated summary

Right ventricular (RV) size and function assessed by multimodality imaging are associated with outcomes in various cardiovascular diseases. Understanding RV anatomy and physiology is crucial for comprehending the strengths and weaknesses of current imaging methods and providing context for these measurements. The adaptation of the RV to different types and severities of stress, especially 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 reviews the standard and novel imaging methods for assessing RV function and discusses the impact of these parameters on outcomes in specific disease states.
