Abstract
As described in Chap. 32, FFR and CFR should—in theory—provide at least in part concordant results: an impaired FFR should always be associated with an impaired CFR (as a demonstration that the epicardial stenosis limits the maximum achievable blood flow) and vice versa. Exceptions are, however, very frequent.
