Assessing the right ventricle by any imaging modality is a challenge because of the thin wall and crescent shape that wraps around the left ventricle. Structured echocardiographic examination using two-dimensional imaging provides a detailed regional and global qualitative assessment for routine evaluation. Quantitation is possible using one or more methods including tricuspid annulus plane systolic excursion, fractional area change, and myocardial performance index but speckle tracking deformation imaging and three-dimensional echocardiography are emerging as more robust quantitative methods. Right ventricular pressures should also be estimated routinely as long as a clear tricuspid regurgitant jet is identified.
