Clinical Anatomy, EarlyView.ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Catheterization and Cardiovascular Interventions, EarlyView.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 ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Rotational atherectomy (RA) has undergone considerable technical modernization in recent years. This study evaluated whether RA performed in the contemporary era was associated with superior cardiovascular outcomes compared with the traditional era. Aims To compare the clinical characteristics and cardiovascular outcomes of patients

Computed Tomography of the Coronary Arteries
SA Heart Journal, 2017 MSCT Coronary Angiography is a fast developing non-invasive diagnostic technique that can detect a coronary stenosis. The detection of a coronary stenosis is hampered by limited image quality and by motion artefacts and extensive calcifications ...

Clinical Impact of Adherence to Fractional Flow Reserve Guidance in Acute Coronary Syndrome
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Fractional flow reserve (FFR) is established to guide revascularization in stable coronary disease and non‐culprit lesions in acute coronary syndromes (ACS). However, real‐world adherence to FFR guidance across the spectrum of ACS presentations, including ambiguous culprit scenarios, remains incompletely characterized.

Maximum Allowable Contrast Dose and Risk of Acute Kidney Injury After Coronary Procedures
Catheterization and Cardiovascular Interventions, EarlyView.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.
