Fractional flow reserve to guide coronary revascularization.
Fractional flow reserve (FFR) has become an increasingly important index for decision making with respect to revascularization of coronary artery stenosis. It is the gold standard to indicate whether a particular stenosis is responsible for inducible ischemia and it is generally accepted that a stenosis with an ischemic value of FFR is responsible for angina pectoris and a worse outcome, and sh...
متن کاملIschemia-based Coronary Revascularization: Beyond Anatomy and Fractional Flow Reserve
Treatment strategies for patients with coronary artery disease (CAD) should be based on objective evidence of inducible ischemia in the subtended myocardium to improve clinical outcomes, symptoms, and cost-effectiveness. Fractional flow reserve (FFR) is the most verified index to-date for invasively evaluating lesion-specific myocardial ischemia. Favorable results from large clinical trials tha...
متن کاملDelineating the guide-wire flow obstruction effect in assessment of fractional flow reserve and coronary flow reserve measurements.
Hemodynamic analysis was conducted to determine uncertainty in clinical measurements of coronary flow reserve (CFR) and fractional flow reserve (FFR) over pathophysiological conditions in a patient group with coronary artery disease during angioplasty. The vasodilation-distal perfusion pressure (CFR-p(rh)) curve was obtained for 0.35- and 0.46-mm guide wires. Our hypothesis is that a guide wire...
متن کاملMeasurement of fractional flow reserve to guide decisions for percutaneous coronary intervention
BACKGROUND Coronary artery disease (CAD) is one of the leading causes of premature death in Germany. Percutaneous coronary interventions (PCI) are frequently performed in patients with angiographically intermediate stenoses. However, the necessity of PCI has not been proven for all patients. Pressure-based fractional flow reserve (FFR) is an invasive test that can be used to assess the function...
متن کاملCost-effectiveness of measuring fractional flow reserve to guide coronary interventions.
BACKGROUND Most patients come to the catheterization laboratory without prior functional tests, which makes the cost-effective treatment of patients with intermediate coronary lesions a practical challenge. METHODS We developed a decision model to compare the long-term costs and benefits of 3 strategies for treating patients with an intermediate coronary lesion and no prior functional study: ...
