Aims: We sought to assess eventual changes in iFR measurements in patients with aortic
stenosis (AS) before and after TAVI in coronary lesions with different degrees of …

The value of fractional flow reserve (FFR) in determining the appropriateness of
percutaneous coronary intervention (PCI) has been well established and incorporated into …

Fractional flow reserve (FFR) measurements can determine the haemodynamic relevance of
coronary artery stenoses. Current guidelines recommend their use in lesions in the absence …

Abstract Purpose of Review The goal of this article is to review the data supporting the use of
fractional flow reserve derived from coronary computed tomography angiography (FFRCT) …

Recent analyses suggest the incidence of acute coronary syndrome is declining in high-and
middle-income countries. Despite this, overall rates of non-ST-elevation myocardial …

Background Quantitative flow ratio (QFR) has a high diagnostic accuracy in assessing
functional stenoses relevance, as judged by fractional flow reserve (FFR). However, its …

Objectives To identify clinical, angiographic and hemodynamic predictors of discordance
between instantaneous wave‐free ratio (iFR) and fractional flow reserve (FFR). Background …

Objectives: The aim of this study was to examine the level of agreement between acute
instantaneous wave-free ratio (iFR) measured across nonculprit stenoses in patients with ST …

Although concomitant coronary artery disease (CAD) is frequent in patients with severe
aortic stenosis (AS), hemodynamic assessment of CAD severity in patients undergoing valve …

Background Nonhyperemic pressure ratios (NHPRs) such as instantaneous wave‐free ratio,
resting full‐cycle ratio, or diastolic pressure ratio have emerged as invasive physiologic …
