Key result
Echocardiographic estimation of left ventricular volume correlated strongly with angiocardiography (r=0.91), though lack of fit occurred in patients with abnormal left ventricular cavity shape.

Does echocardiography accurately estimate left ventricular size compared to angiocardiography?
Effect estimate: r=0.91
Echocardiography provides a reliable estimate of left ventricular volume compared to angiography, though accuracy is reduced in patients with abnormal left ventricular cavity shapes.
D G Gibson (1973) conducted an observational in Patients requiring left ventricular dimension estimation (n=50). Echocardiography vs. Angiocardiography was evaluated on Correlation of left ventricular volume estimation (r=0.91). Echocardiographic estimation of left ventricular volume correlated strongly with angiocardiography (r=0.91), though lack of fit occurred in patients with abnormal left ventricular cavity shape.
