Table 1 The pressure difference in the artery zone and FFR calculation under the two outlet boundary conditions
From: Influence of microcirculation load on FFR in coronary artery stenosis model
Outlet | The peak Pressure (Pa) | The low pressure (Pa) | Fluctuation range (Pa) | FFR | AS(%) | |||
|---|---|---|---|---|---|---|---|---|
Pa | Pd | Pa | Pd | Pa (%) | Pd (%) | |||
Microcirculation Seepage Load | 7170 | 5480 | 1980 | 1760 | 5190 (72.4%) | 3720 (67.9%) | 0.813 | 75% |
Pressure Load | 4540 | 2870 | 2960 | 2740 | 1580 (34.8%) | 130 (4.53%) | 0.776 | 75% |
