Differences in graft flowmetry and its derivatives between patent and occluded grafts.
| Parameter | Patent Grafts (n = 17) | Occluded Grafts (n = 5) | p |
|---|---|---|---|
| Flow during cardioplegia | 100.2 ± 27.7 | 49.2 ± 31.5 | 0.0022 |
| CR cardioplegia | 1.03 ± 0.33 | 2.70 ± 1.57 | 0.0029 |
| Mean TTF flow | 54.2 ± 25.5 | 30.2 ± 17.1 | 0.06 |
| CR TTF | 1.74 ± 0.22 | 6.38 ± 9.92 | 0.09 |
| PI | 1.7 ± 0.6 | 2.3 ± 1.6 | 0.44 |
CR: coronary resistances, TTF: transit time flowmetry, PI: pulsatility index.
