Fractional flow reserve in unstable angina and non-ST-segment elevation myocardial infarction experience from the FAME (Fractional flow reserve versus Angiography for Multivessel Evaluation) study [PDF]

, 2011
The use of fractional flow reserve (FFR) to guide percutaneous coronary intervention (PCI) is well established in stable angina (SA) but has not been prospectively researched in unstable angina (UA) or non–ST-segment elevation myocardial infarction ...

Diagnostic Accuracy of Diastolic Fractional Flow Reserve for Functional Evaluation of Coronary Stenosis

JACC: Asia, 2021
Background: In the resting conditions, narrowing the window of coronary pressure measurements from the whole cardiac cycle to diastole improves diagnostic performance of coronary pressure–derived physiological index. However, whether this also applies to

Effect of the ratio of vessel-specific volume to fractional myocardial mass on fractional flow reserve

Experimental Biology and Medicine, 2021
This study aimed to examine whether the ratio of vessel-specific coronary arterial lumen volume to the fraction of myocardial mass (V R /M R ) affects myocardial ischemia. We proposed a calculation method for V R /

Measurement of fractional flow reserve in a patient with combined myocardial bridging and coronary fixed stenosis [PDF]

, 2012
A segment of coronary arteries traveling through the myocardium is known as myocardial bridging. Several reports have shown reduced fractional flow reserve (FFR) associated with myocardial bridging.

Dobutamine-induced wall motion abnormalities: Correlations with myocardial fractional flow reserve and quantitative coronary angiography [PDF]

, 1996
Objectives. This study evaluated both the relation between dobutamine-induced wall motion abnormalities and the physiologic and morphologic features of epicardial coronary artery stenoses and the impact of the extent of the area at risk on the ...

The Impact of Myocardial Bridging on Fractional Flow Reserve

, 2022
Arterial stenosis is a problem of immediate significance, as cardiovascular disease is the number one leading cause of death worldwide. Fractional flow reserve (FFR) was proposed to evaluate the functional severity of coronary plaque-induced stenosis more accurately. FFR relies on invasive pressure measurements, while computational fluid dynamics (CFD)
