During these two years, the number of coronary pressure measurements performed worldwide both during diagnostic and interventional procedures has increased almost exponentially. Mos

Marie Daycular disease on coronary blood flow.. As a result, there is a wide variation in normal values and a large overlap between normal and pathologic values, i.e. values associated with inducible ischemia or not.. Therefore, clinical decision-making based upon absolute coronary flow reserve, remains difficult.

The Coronary Circulation,ell understood. This chapter does not claim to be an extensive review of the physiology of the coronary circulation but aims at providing the reader with the anatomic and physiologic background required to understand the principles, advantages, and limitations of the concept of pressure-derived frac
