Stenosis, FF and translesional pressure gradient before and after intervention
| Before intervention |
After intervention |
|||
|---|---|---|---|---|
| all patients (n = 19)a | patients with PTA or stenting (n = 13)b | patients with PTA or stenting (n = 13)b | patients on conservative management (n = 5) | |
| Stenosis, % | 74.8±8.3 | 76.2 ± 8.3 | 24.7 ±11.7 | 70.1 ±7.7 |
| FF | 0.70±0.17 | 0.66 ± 0.18 | 0.88 ±0.09 | 0.79 ±0.12 |
| Pa-Pd gradient, mm Hg | 25.6±17.9 | 29.9 ± 19.8 | 10.9 ±10.3 | 15.8 ±8.9 |
PTA = Percutaneous transluminal angioplasty. Figures are presented as mean ± SD.
a
1 patient had incomplete preintervention data, hence his data were not presented in this table.
b
1 more patient had incomplete postintervention pressure measurements due to technical issues with the machine, and not due to the patient or the procedure, hence his data were also not included in this table.
