Combined functional and anatomical diagnostic endpoints for assessing arteriovenous fistula dysfunction

Figure 7 Contribution of viscous losses and losses due to momentum changes to the total pressure drop in a stenosed coronary artery with the increase in the percentage area stenosis[65]. Here, the pressure drop values at different stenosis severity were ob-tained under the corresponding hyperemic flow for coronary arteries. Also, lm and dm represent the length of stenosis throat and diameter of throat, respectively. Reprinted from ref. [65], with permission.
