Does pulse echo Doppler velocimetry accurately assess the presence and severity of aortic valve disease and prosthesis function?
Pulse echo Doppler velocimetry provides a reliable, non-invasive method for assessing aortic valve disease severity and prosthesis function.
Veyrat et al. (1980) conducted an observational in Aortic valve disease and aortic prostheses (n=63). Pulse echo Doppler velocity recordings was evaluated on Sensitivity and specificity for detecting type and severity of aortic valve lesions. Pulse echo Doppler velocity recordings accurately assessed the presence and severity of aortic valve lesions, with sensitivity and specificity ranging between 80% and 94%.
