Standardization of Fractional Flow Reserve Measurements.
Pressure wire-based fractional flow reserve is considered the standard of reference for evaluation of the ischemic potential of coronary stenoses and the expected benefit from revascularization. Accordingly, its application in daily practice or for research purposes has to be as standardized as possible to avoid technical or operator-related artifacts in pressure recordings. This document propo...
متن کاملCoronary flow reserve by contrast enhanced transesophageal coronary sinus Doppler measurements can evaluate diabetic microvascular dysfunction.
BACKGROUND This study was undertaken to investigate whether coronary flow reserve (CFR) using coronary sinus flow (CSF), which can be measured by transesophageal Doppler echocardiography (TEDE), especially when contrast enhanced, is useful in evaluating microvascular dysfunction in patients with diabetes mellitus (DM). METHODS AND RESULTS CSF recordings using contrast enhanced TEDE were perfo...
متن کاملImpact of Right Atrial Pressure on Fractional Flow Reserve Measurements: Comparison of Fractional Flow Reserve and Myocardial Fractional Flow Reserve in 1,600 Coronary Stenoses.
OBJECTIVES This study sought to assess the impact of a wide range of mean right atrial pressure (Pra) on fractional flow reserve (FFR) measurements. BACKGROUND FFR invasively assesses the ischemic potential of coronary stenoses. FFR is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The Pra is considered to have little impac...
متن کاملIntracoronary Versus Intravenous Adenosine-Induced Maximal Coronary Hyperemia for Fractional Flow Reserve Measurements
BACKGROUND Maximal hyperemia is the critical prerequisite for fractional flow reserve (FFR) assessment. Despite intravenous (IV) adenosine currently being the recommended approach, intracoronary (IC) administration of adenosine constitutes a valuable alternative in everyday practice. However, it is surprisingly unclear which IC strategy allows the achievement of FFR values that are comparable t...
متن کاملFractional Flow Reserve
Traditionally, coronary artery disease was assessed using coronary angiographic guidance. Significant lesions were determined by the coronary angiographer. However, interobserver variability showed a significant limitation of interpretation of coronary angiography. Stent deployment and apposition were also evaluated based on angiographic appearance only. Risk factors for stent thrombosis and in...
