Normal values of CFR widely vary from patient to patient and strongly depend on the current hemodynamic state (as shown in chapter 9), extent of collaterals (chapter 16), and the technique used to measure that index. When CFR is assessed by flow velocity ratios, an additional c

Since these early days, the interest in measuring distal coronary pressure has fluctuated between enthusiasm for having a simple index to assess coronary hemodynamics and disillusion due to the inconsistency of the results..

Marie DayThe present chapter aims at providing the reader with the practical aspects of coronary pressure measurements in humans. The technical requirements, equipment, “tips and tricks” of the procedure itself, and methods to induce hyperemia are reviewed. Potential pitfalls to be aware of, are discussed in chapter 6.

In addition to feasibility and clinical relevance, reproducibility (or absence of variability) is another crucial characteristic of any new diagnostic test. A measurement which is either difficult to obtain, of little clinical relevance, or highly variable, would be clinical nonsense.
