Key result
B-scan ultrasonography area ejection fraction correlated strongly with ventriculographic silhouettes (r=0.92) and biplane volume ejection fraction (r=0.87) for assessing left ventricular function.
Why the study?
Does B-scan ultrasonography accurately assess left ventricular geometry and function compared to biplane cine angiography in patients with cardiac disorders?
Cross-Sectional (n=25)
Does B-scan ultrasonography accurately assess left ventricular geometry and function compared to biplane cine angiography in patients with cardiac disorders?
Effect estimate: r = 0.92
B-scan ultrasonography provides a safe, noninvasive method that correlates well with angiography for assessing left ventricular geometry and function, even in patients with asynergy.
No takes yet. Share an insight, caveat, or question.
May support noninvasive LV assessment in cardiac patients; leaves open prospective validation against angiography.
Teichholz et al. (1974) conducted a cross-sectional in various cardiac disorders (n=25). B-scan ultrasonography vs. biplane cine angiography was evaluated on Correlation between area ejection fractions determined from B-scan and ventriculographic silhouettes (r = 0.92). B-scan ultrasonography area ejection fraction correlated strongly with ventriculographic silhouettes (r=0.92) and biplane volume ejection fraction (r=0.87) for assessing left ventricular function.
