A multi-artery Fractional Flow Reserve (FFR) approach for handling coronary stenosis-stenosis interaction in the multi-vessel disease (MVD) arena

摘要

Background: FFR is a widely accepted 'gold standard' of coronary stenosis severity indices in MVD cases. Contrary to this conception, reality shows that true FFR values that are equal to the real fractional remnant blood flow exist only in single vessel disease (SVD) cases and in those MVD cases that are decomposable into independent SVD cases.
