Indications for transcatheter aortic valve replacement (TAVR) have steadily increased over
the last decade since the first trials including inoperable or very high risk patients. Thus …

Aortic stenosis (AS) and coronary artery disease (CAD) frequently coexist, with up to two
thirds of patients with AS having significant CAD. Given the challenges when both disease …

The clinical value of fractional flow reserve and non-hyperaemic pressure ratios are well
established in determining an indication for percutaneous coronary intervention (PCI) in …

Background The Murray law‐based quantitative flow ratio (μQFR) is a novel technique that
simulates fractional flow reserve (FFR) from a single angiographic view. However, the …

Background Quantitative flow ratio (QFR) is a novel angiography-derived index aimed to
assess the functional relevance of coronary stenoses without pressure wires and adenosine …

BACKGROUND: Angiography-derived computational physiology is an appealing alternative
to pressure-wire coronary physiology assessment. However, little is known about its …

Objective: The study aimed to investigate the diagnostic accuracy of Murray law based
quantitative flow ratio (μQFR) from a single angiographic view in patients with abnormal …

Coronary physiologic assessment is performed to measure coronary pressure, flow, and
resistance or their surrogates to enable the selection of appropriate management strategy …

Introduction and objectives Quantitative flow ratio (QFR) is a novel noninvasive method for
evaluating coronary physiology. However, data on the QFR in patients with aortic stenosis …

Background Coronary artery disease (CAD) is common in patients with aortic valve stenosis
(AS) ranging from 60% to 80%. The clinical and prognostic role of coronary artery lesions in …
