Assessment of the right ventricle by echocardiography: a primer for cardiac sonographers.
The assessment of right ventricular (RV) structure and function by echocardiography has been improved by advancements that include Doppler tissue imaging, strain imaging, and three-dimensional imaging. Doppler tissue imaging and strain imaging can be useful for the assessment of regional RV systolic and diastolic function. Three-dimensional imaging has been reported to determine RV volumes and ejection fraction, which have previously been cumbersome to measure with conventional two-dimensional echocardiography. This article addresses the role of conventional and newer methods of echocardiography to assist sonographers in understanding the technical considerations, limitations, and pitfalls of image acquisition and analysis of RV structure and function.
