Key result
Real-time three-dimensional echocardiography accurately quantified right ventricle cavity volumes without geometric assumptions, showing excellent correlation with static volumes (B-scan, r = 0.99; P<.001).
Why the study?

Effect estimate: r = 0.99
p-value: p=<.001
Real-time three-dimensional echocardiography can accurately quantify right ventricle cavity and stroke volumes without geometric assumptions in an in vitro model.
Schindera et al. (2002) studied Right ventricular volume assessment (n=39). Real-time three-dimensional echocardiography vs. Water displacement was evaluated on Correlation between real-time three-dimensional echocardiographic determinations and static volumes (r = 0.99, p=<.001). Real-time three-dimensional echocardiography accurately quantified right ventricle cavity volumes without geometric assumptions, showing excellent correlation with static volumes (B-scan, r = 0.99; P<.001).
