Accuracy of Doppler echocardiography to estimate key hemodynamic variables in subjects with normal left ventricular ejection fraction.
The accuracy of Doppler echocardiography to estimate key hemodynamic parameters in subjects with normal left ventricular ejection fraction (LVEF) has not been fully investigated. ⋯ Single Doppler echocardiography parameters are not accurate enough to reliably estimate key hemodynamic parameters, particularly PCWP, in subjects with normal LVEF.
