Pulse Wave Velocity (PWV) is a very useful index for the systemic assessment of the cardio vascular diseases. To explore more effective usage of the PWV for the localized diseases, we analyzed the fluid-solid coupled problem of the stenosed artery with various area reductions ranging from 0% to 50% by using our application software. It was assumed that the stenosed artery is axisymmetric and the shape of the stenosis is given as the Gaussian curve. It was found that the PWV of the stenosed artery increases with the increase of the severity of the stenosis and the difference of the PWV between the stenosed and straight arteries reached 0.9m/s for the stenosed artery with an area reduction of 50%.
