Abstract:BACKGROUND:
Quantitative flow ratio derived from computed tomography angiography (CT-QFR) and invasive coronary angiography (Murray law–based quantitative flow ratio [μQFR]) are novel approaches enabling rapid computation of fractional flow reserve without the use of pressure guidewires and vasodilators. However, the feasibility and diagnostic performance of both CT-QFR and μQFR in evaluating complex coronary lesions remain unclear.
