Fractional flow reserve measurement modification with monorail pressure catheter.
A number of symptomatic patients with coronary artery disease undergo revascularization without definite evidence that particular coronary stenosis is responsible for their symptoms [1]. Currently, the borderline coronary artery stenoses are most commonly assessed by intravascular ultrasound and fractional flow reserve (FFR) alongside with quantitative coronary angiography [2]. FFR measurement,...
متن کاملHybrid Instantaneous Wave-Free Ratio–Fractional Flow Reserve versus Fractional Flow Reserve in the Real World
BACKGROUND The instantaneous wave-free ratio (iFR) is a novel method to assess the ischemic potential of coronary artery stenoses. Clinical trial data have shown that iFR has acceptable diagnostic agreement with fractional flow reserve (FFR), the reference standard for the functional assessment of coronary stenoses. This study compares iFR measurements with FFR measurements in a real world, sin...
متن کاملResting Pd/Pa measured with intracoronary pressure wire strongly predicts fractional flow reserve.
OBJECTIVE To investigate the relationship between resting distal coronary pressure to aortic pressure ratio (Pd/Pa) and fractional flow reserve (FFR) obtained during maximal hyperemia. BACKGROUND FFR is an invasive index of the functional severity of a coronary artery stenosis determined from coronary pressure measurements. It is generally believed that there is little correlation between res...
متن کاملCoronary pressure measurement and fractional flow reserve.
The shortcomings of coronary arteriography to assess the physiological significance of coronary stenoses have been recognised for decades ; therefore, the importance of additional physiological techniques is beyond doubt. One of the currently available physiological techniques is coronary pressure measurement, which has emerged over the past few years as a major step forward in the invasive ass...
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...
