IntRoductIon In current catheter research, there are 3 main directions with respect to fractional flow reserve (FFR), including instantaneous wave‐free ratio, noninvasive measurement of FFR, and FFR transferred from coronary circulation to other ischemia‐inducing circulation. Recently, an interesting study was published, in which FFR was performed to diagnose and guide stenting in chronic mesen...

Fractional flow reserve (FFR) is considered nowadays as the gold standard for invasive assessment of physiologic stenosis significance and an indispensable tool for decision-making in coronary revascularization. Robust studies have shown that FFR is more effective in accurately identifying which lesions should be stented, and revascularization guided by FFR improves the outcome of coronary arte...

Rev Esp Cardiol. 2005;58(9):1117 1117 A 69-year-old patient with a history of hypertension was admitted to the hospital for an acute coronary syndrome. Coronary arteriography showed a myocardial bridge at the mid-distal third of the left anterior descending artery with marked systolic compression. The fractional flow reserve (FFR) following intravenous infusion of adenosine (140 μg/kg) was 0.68...

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...
