Key result
Echocardiography in 128 patients with aortic valve disease demonstrated distinct patterns of pressure overload in aortic stenosis and volume overload in aortic regurgitation.
Why the study?
How do echocardiographic measurements of left ventricular function differ among patients with aortic stenosis, aortic regurgitation, and mixed aortic valve disease?
Observational (n=128)
How do echocardiographic measurements of left ventricular function differ among patients with aortic stenosis, aortic regurgitation, and mixed aortic valve disease?
Echocardiography can distinguish between pressure and volume overload patterns in different types of aortic valve disease and identify mechanisms of left ventricular failure.

Echocardiographic overload patterns may refine LV assessment in aortic valve disease; leaves open prognostic or therapeutic utility.
Ian G. McDonald (1976) conducted an observational in isolated aortic valve disease (n=128). Echocardiography was evaluated on Left ventricular size and contraction (LVIDd, PWTd, FS, LVSV). Echocardiography in 128 patients with aortic valve disease demonstrated distinct patterns of pressure overload in aortic stenosis and volume overload in aortic regurgitation.
