Physiological Assessment During Interventional Procedures

Chapter

Abstract

Angiography identifies minimal luminal diameter but does not calculate the minimal luminal area. The operator should keep in mind the limitations of angiography. A significant lesion may be missed due to its eccentric nature, location in a highly tortuous artery, ostial position, or length. In addition, moderate (50–70 %) lesions may be hemodynamically significant (see Fig. 4.1). Fractional flow reserve [FFR] provides objective evidence for functional significance. FFR-guided decision making provides better clinical outcomes when compared to angiography, and therefore every operator must be familiar with this technique.1
