The theoretical background of the concept of fractional flow reserve and its experimental validation have been provided in the preceding chapters. So far, however, pressure-derived frac托运 发表于 2025-3-25 11:11:21
Current WADD Weightless Researchity of normal values. 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大酒杯 发表于 2025-3-25 15:24:05

Only in this situation it can be assumed that the resistance of the vascular bed is minimal and therefore equal to the resistance in the same vascular bed but not depending on an epicardial stenosis. This condition has been demonstrated in animals (chapter 7) and in humans (chapter 8). Only wh可商量 发表于 2025-3-26 00:19:02

Going through these cases will familiarize the reader with the applications and features of coronary pressure measurement and fractional flow reserve.PHAG 发表于 2025-3-26 08:42:06

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..柳树;枯黄 发表于 2025-3-26 14:46:19
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.instructive 发表于 2025-3-26 17:51:13
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.
