Methods: 57subjects who underwent transthoracic echocardiography including real time 3-dimensional image acquisition of right ventricle before and after hemodialysis were enrolled. End-diastolic and end-systolic volumes were obtained from right ventricular real time 3-dimensional image. Right ventricular stroke volume and ejection fraction were also calculated. Parameters representing right ventricular size and function based on 2-dimensional echocardiography were obtained from real time 3-dimensional image.
Results: The right ventricular functional parameters from real time 3-dimensional echocardiography could be easily obtained from commercially available software with other 2-dimensional functional parameters. And right ventricular ejection fraction obtained from real time 3-dimensional echocardiography was less dependent on acute preload changes.
Conclusion: Right ventricular ejection fraction based on real time 3-dimensional echocardiography can be used as more reliable parameter for right ventricular function irrespective of volume status.
