Research Article: Accuracy and Reproducibility of Coronary Angiography-Derived Fractional Flow Reserve in the Assessment of Coronary Lesion Severity
Introduction:
Wire-based fractional flow reserve (FFR) is the gold standard for coronary revascularization in patients with stable ischemic heart disease, , and its favorable clinical outcomes have been demonstrated in several multicenter randomized trials. – However, the use of wire-based FFR is limited by its high cost, additional time to perform, and patient discomfort. , Over the past decade, four CFD-derived FFR techniques have been developed to avoid the need of using an invasive pressure wire: quantitative flow ratio…
