Does apical orthogonal 2-D echocardiography accurately estimate left ventricular volume and ejection fraction compared to biplane cine-angiography in patients undergoing cardiac catheterization?
Effect estimate: r=0.98
Apical orthogonal 2-D echocardiography provides highly accurate estimates of left ventricular volumes and ejection fraction compared to the invasive cine-angiography standard.
Jenni et al. (1981) conducted a cross-sectional in Patients undergoing biplane left ventricular cine-angiography (n=42). Two-dimensional echocardiography vs. Biplane left ventricular cine-angiography was evaluated on Left ventricular end-diastolic volume (r=0.98). Two-dimensional echocardiography yielded strong correlations with cine-angiography for estimating left ventricular end-diastolic volume (r=0.98) and end-systolic volume (r=0.97).
