Hemodynamic rounds series II: Coronary hemodynamics for angioplasty and stenting after myocardial infarction: use of absolute, relative coronary velocity and fractional flow reserve.
The application of absolute coronary velocity reserve, relative coronary velocity reserve, and pressure-derived fractional flow reserve of the myocardium may have influence on decision making for angioplasty and stenting in patients after myocardial infarction. This case highlights the use and limitations of these techniques in the setting of myocardial infarction where absolute coronary flow reserve may be commonly compromised. The role for absolute, relative coronary, and fractional flow reserve are discussed.
