Does echocardiographic measurement of aortic root diameter correlate with angiocardiographic measurement in patients with heart disease?
Effect estimate: r=0.944
p-value: p=<0.001
Echocardiography is a simple, safe, and reliable noninvasive method for estimating aortic root diameter that correlates highly with invasive angiocardiography.
Furukawa et al. (1976) conducted a cross-sectional in Various heart diseases and normal subjects (n=324). Echocardiographic measurement of aortic root diameter vs. Angiocardiographic measurement was evaluated on Correlation between aortic root diameters measured by echocardiograms and angiocardiograms (r=0.944, p=<0.001). Echocardiographic measurements of aortic root diameter showed a highly significant correlation with angiocardiographic measurements (r=0.944, p<0.001), proving it a reliable noninvasive method.
