Key Points The myocardium subtending a CTO is universally ischemic at rest measured by iFR. In 30% of vessels, iFR remains in the ischemic range despite angiographic optimization after PCI. In approximately half of the ischemic vessels after PCI, iFR can be improved with further intervention. The strategy of functionally optimized coronary intervention is feasible in a CTO.
