Key result
Two-dimensional echocardiography (triggered B-scan) correlated strongly with single-plane angiography for assessing left ventricular chamber volume (r=0.88) and ejection fraction (r=0.81).
Why the study?
Does two-dimensional echocardiography accurately determine left ventricular volume and ejection fraction compared to single-plane angiography in patients undergoing routine angiography?
Observational (n=20)
Does two-dimensional echocardiography accurately determine left ventricular volume and ejection fraction compared to single-plane angiography in patients undergoing routine angiography?
Effect estimate: r 0.88
Two-dimensional echocardiography provides a safe, non-invasive, and reliable alternative to angiography for determining left ventricular volume and ejection fraction, particularly in patients with dilated hearts.

May support 2D echo for LV assessment; leaves open prospective validation before clinical adoption.
Gehrke et al. (1975) conducted an observational in Undergoing routine left ventricular single-plane angiography (n=20). Ultrasonic triggered B-scan technique (two-dimensional echocardiography) vs. Left ventricular single-plane angiography was evaluated on Correlation of left ventricular chamber volume and ejection fraction (r 0.88). Two-dimensional echocardiography (triggered B-scan) correlated strongly with single-plane angiography for assessing left ventricular chamber volume (r=0.88) and ejection fraction (r=0.81).
