fractional flow reserve ppt

Fractional flow reserve is defined as the pressure after distal to a stenosis relative to the pressure before the stenosis. FFR immediately after stenting to assess the impact of the treatment on coronary flow and the possible residual stenosis has been poorly investigated and data on this specific FFR application are sparse.

Use of FFR was associated with simplified surgical procedures but at 1-year follow-up no difference in overall graft patency 80 vs. The original description of FFR required the induction of maximal hyperemia to achieve near linear correlation between coronary pressure and blood flow.

The result is an absolute. Despite the overall trend towards more physiology-guided revascularization there remains a gap between guideline recommendations and the clinical. The index FFR Fractional Flow Reserve is based upon the two following principles.

P 0885 or in the composite of death myocardial infarction target vessel revascularization and stroke was found in the GRAft patency after FFR-guided versus angiography-guided CABG. Sensitivity 88. Fractional flow reserve FFR utilizes a specialized guide wire to measure blood pressure within a coronary artery.

In the FAME. In other words FFR expresses the maximal flow down a vessel in the presence of a stenosis compared to the. A normal value is 1 while values.
