Accuracy of a virtual PCI planner based on coronary CT angiography in calcific lesions.

Fractional Flow Reserve (FFR) measured after percutaneous coronary intervention (PCI) quantifies the degree of functional revascularization and is associated with improvement in angina and clinical outcomes. 1 Hwang D.
