Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The FFR measurement reliability is assessed by two measures. First reliability is assessed by tracking and recording the drift caused by the pressure guidewire residing within the coronary artery. This is determined by the value of Pd/Pa before and after the procedure when pulled back just outside the guiding catheter. Secondly, FFR reliability is assessed by the stability of Pd/Pa during constant hyperemia. | — |
Secondary
| Measure | Time frame |
|---|---|
| The wire handling performance is assessed by scoring both wires by the same investigator in the same patient. The following characteristics are scored on a 5 point scale: torquability, steerability, pushability and support. The wire performance is also assessed by measuring the time it takes to reach and cross the lesion. | — |
