Addetia K, et al. - Via performing this review, researchers sought to delineate the novel utility of 3-dimensional echocardiography in determining right ventricular (RV) size and function, in juxtaposition with what is currently available using 2-dimensional echocardiography. Three-dimensional echocardiography allows assessment of both volume and ejection fraction of the RV with precision and reproducibility close to that of cardiovascular magnetic resonance imaging. In addition, device leads, tricuspid valve leaflets, and RV wall–motion abnormalities could be assessed with 3-dimensional RV data sets as these can be cropped, sliced, and rotated. Many of the limitations linked with conventional 2-dimensional echocardiography are managed with the use of 3-dimensional echocardiography. These observations support its potential to render the detailed information needed for the complex clinical decision-making that demands accurate, quantitative information about the RV.
