Several novel software systems have been developed for the reconstruction of the coronary artery tree and the calculation of fractional flow reserve (FFR) from coronary artery angiography images without coronary artery instrumentation: FFRangio, Computational pressure-flow dynamics derived FFR, quantitative flow ratio (QFR), and vessel FFR. In this report, we review the current evidence on each software, their contemporary use, and future directions.
Keywords: angiography; coronary revascularization; fractional flow reserve software.
