Choosing the optimal wall shear parameter for the prediction of plaque location—a patient-specific computational study in human right coronary arteries
BACKGROUND: Average wall shear–stress (AWSS), average wall shear–stress gradient
(AWSSG), oscillatory shear index (OSI) and relative residence time (RRT) are believed to
predict areas vulnerable to plaque formation in the coronary arteries. Our aim was to
analyze the correlation of these parameters in patients' vessels before the onset of
atherosclerosis to the specific plaque sites thereafter, and to compare the parameters'
sensitivity and positive predictive value. METHODS: We obtained 30 patient-specific …
