ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Maximum Allowable Contrast Dose and Risk of Acute Kidney Injury After Coronary Procedures
ABSTRACT Background Recent studies have questioned whether iodinated contrast is causally related to acute kidney injury (AKI). AIM We pursed a contemporary analysis to determine the impact of contrast dose on AKI following coronary procedures in an era of lower contrast doses and less nephrotoxic agents.

Impaired Flow and Physiology in Coronaries With Anomalous Origin From the Opposite Sinus of Valsalva
ABSTRACT Background Anomalous Aortic Origin of a Coronary Artery (AAOCA) high‐risk anatomical features (intramural segment, acute take‐off angle, slit‐like ostium) cause coronary stenosis leading to myocardial infarction. How these features alter coronary physiology remains unclear.

Biventricular Pressure‐Volume Loop Analysis in an LVAD Patient Optimized With Impella RP Flex
ABSTRACT Right ventricular (RV) failure after left ventricular assist device (LVAD) implantation is a serious complication which may necessitate temporary mechanical support in refractory cases. Here we describe a 63‐year‐old man with end‐stage ischemic cardiomyopathy and severe combined pre‐ and post‐capillary pulmonary hypertension who developed ...

ABSTRACT Background Cangrelor reduces thrombotic events in patients undergoing percutaneous coronary intervention (PCI), with the advantage of rapid onset and offset. However, premature discontinuation may increase the risk of acute thrombosis for patients undergoing complex/high‐risk PCI (CHIP).
