Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Correlation of cDSA-derived parameters and Doppler flow velocity-derived parameters of microvascular resistance during hyperemic flow and coronary flow reserve, pre-and post PCI. Patiënts will receive a PCI of the LAD following standard of care. However, before the PCI 2 additional angiograms will be acquired, before and after administration of adenosine. Simultaneously, intracoronary flow and pressure will be measured with a Combowire positioned in the LAD. Following the PCI the same will be repeated. | — |
