Vascular properties may confound aortic Doppler LV assessment; leaves open reliability without vascular adjustment in humans.
Do systemic vascular characteristics influence the early systolic aortic ultrasound Doppler signal used for assessing left ventricular function?
Maximal velocity and acceleration from aortic Doppler signals can only reliably assess left ventricular function when vascular characteristics are constant or can be estimated.
Janerot-Sjöberg et al. (1993) studied this question.
