Coronary Computed Tomography (CT) Angiography as a Predictor of Cardiac and Noncardiac Vascular Events in Asymptomatic Type 2 Diabetics: A 7‐Year Population‐Based Cohort Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundType 2 diabetics are at increased risk for vascular events, but the value of further risk stratification for coronary heart disease (CHD) in asymptomatic subjects is unclear.

Interpreting results of coronary computed tomography angiography-derived fractional flow reserve in clinical practice

, 2017
The application of computational fluid dynamics to coronary computed tomography angiography allows Fractional Flow Reserve (FFR) to be calculated non-invasively (FFRCT), enabling computation of FFR from coronary computed tomography angiography acquired ...

Sheath‐to‐Artery Diameter Ratio: A Robust Predictor of Early Access‐Site Adverse Events in Percutaneous Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vascular access site complications (VASCs) remain an important source of morbidity following percutaneous interventions. Although the sheath‐to‐femoral artery ratio is a recognized risk factor in transcatheter aortic valve implantation (TAVI), its role across a broader range of femoral procedures is less well defined.

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

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 ...

Evaluating the Impact of Enhanced Stent Visualization on PCI Outcomes in Older Patients With Multivessel Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Optimal stent expansion is a key determinant of long‐term outcomes after PCI. Intravascular imaging provides the most accurate assessment of stent deployment but remains underused, especially in older patients with MI and multivessel disease.

Fractional Flow Reserve Measurement by Coronary Computed Tomography Angiography: A Review with Future Directions

Cardiovascular Innovations and Applications, 2016
Invasive fractional flow reserve (FFR) measurement is currently the gold standard for coronary intervention. FFR measurement by coronary computed tomography angiography (FFRCT) is a novel and promising imaging technology that permits noninvasive ...

Temporal Trends and Prognosis in Rotational Atherectomy: A Comparison of Contemporary and Traditional Eras

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

Left ventricular thrombus attenuation characterization in cardiac computed tomography angiography

, 2012
BACKGROUND: Because of their similar visual appearance, differentiation of left ventricular thrombotic material and myocardial wall can be difficult in contrast-enhanced coronary computed tomography (CT) angiography.

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.
