Role of fractional and coronary flow reserve in clinical decision making in intermediate coronary lesions

摘要: Adequate patient selection for percutaneous coronary intervention is of the greatest importance in order to minimize early and late complications. Therefore, objective evidence myocardial ischemia mandatory management patients with artery disease, particular multivessel disease those intermediate lesions (40–70% diameter stenosis on angiography). The use sensor-equipped guidewires assessment functional lesion severity has become extensive cardiac catheterization laboratory. hemodynamic indices derived from intracoronary pressure or flow measurements, fractional reserve reserve, show a high agreement noninvasive stress testing. Furthermore, deferral hemodynamically nonsignificant associated low major adverse event rate. However, since these are based either flow, they do not investigate hemodynami...
