Why the study?
Do single- and 2-beat real-time 3D echocardiography provide accurate left ventricular volume and ejection fraction measurements compared to 4-beat acquisition and CMR?
Do single- and 2-beat real-time 3D echocardiography provide accurate left ventricular volume and ejection fraction measurements compared to 4-beat acquisition and CMR?
2-beat real-time 3D echocardiography offers similar accuracy to 4-beat acquisition for LV volumes and EF with fewer stitching artifacts, whereas single-beat acquisition underestimates LVEF.
No takes yet. Share an insight, caveat, or question.
Supports 2-beat RT3DE for LVEF assessment with fewer artifacts than 4-beat; leaves open prospective validation versus CMR.
Macron et al. (2010) studied this question.
