Table 7.
Spatial distribution of coronary flow for a large subtree implanted at three axial locations in an LV with a uniform thickness of 12.3 mm
| Axial Position | Subepicardium | Midwall | Subendocardium | Qendo/Qepi |
|---|---|---|---|---|
| Base | 1.51 (+6.3) | 1.45 (+14.2) | 1.28 (+25.5) | 1.44 (+18.0) |
| Center | 1.53 (+9.3) | 1.47 (+12.2) | 1.27 (+32.3) | 1.41 (+21.1) |
| Apex | 1.52 (+8.6) | 1.36 (+7.1) | 1.07 (+35.4) | 1.2 (+25.0) |
The table lists the mean values of terminal precapillary flows (qterm) at 3 transmural regions and the ratio of perfusion densities (Qendo/Qepi) in outer layers of the left ventricle (LV). Value in brackets is the % change in the mean value of qterm or Q in a uniformly thick LV from the corresponding value in a nonuniformly thick LV (Table 3). n = 8,634 vessels.
