Background Coronary physiology measurement in serial coronary lesions with multiple
stenoses is challenging. Therefore, we evaluated the feasibility of Murray fractal law‐based …

Background In ST‐segment–elevation myocardial infarction, angiography‐based complete
revascularization is superior to culprit‐lesion‐only percutaneous coronary intervention …

Background: Quantitative flow ratio (QFR) has been introduced as a novel angiography-
based modality for fast hemodynamic assessment of coronary artery lesions and validated …

The feasibility and prognostic value of quantitative flow ratio (QFR) after percutaneous
coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) patients …

Background: A novel index of the functional severity of coronary stenosis, quantitative flow
ratio (QFR), may not consider the amount of viable myocardium in prior myocardial infarction …

Background Revascularization of left main coronary artery (LMCA) stenosis is mostly based
on angiography. Indices based on angiography might increase accuracy of the decision …

Background Intravascular ultrasound (IVUS) provides good insight into lumen boundary and
plaques; however, it is still difficult to detect functionally significant stenosis from IVUS …

Genesis of atherosclerotic lesions in the human arterial system is critically influenced by the
fluid mechanics. Applying computational fluid dynamic tools based on accurate coronary …

Introduction Non-obstructive coronary arteries (NOCA) are present in 39.7% to 62.4% of
patients who undergo elective angiography. Coronary microcirculation (< 400 µm) is not …

Despite the evidence of improved patients' outcome, fractional flow reserve (FFR) is
underused in current everyday practice. We aimed to evaluate the feasibility of a novel …
