Diagnostic Accuracy of a Machine-Learning Approach to Coronary Computed Tomographic Angiography–Based Fractional Flow Reserve: Result From the MACHINE Consortium

Circulation Cardiovascular Imaging, 2018
Background: Coronary computed tomographic angiography (CTA) is a reliable modality to detect coronary artery disease. However, CTA generally overestimates stenosis severity compared with invasive angiography, and angiographic stenosis does not ...

Management of Cardiovascular Health Issues in Turner Syndrome: Expert Insights and Expanded Recommendations From the 2024 Guideline Development Team

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner syndrome (TS) is frequently complicated by congenital heart disease (CHD). While left‐sided lesions such as bicuspid aortic valve (BAV) and coarctation of the aorta are the most common structural heart lesions in TS, other anomalies, such as aortic arch malformations, hypoplastic left heart syndrome (HLHS), persistent left superior vena

Retinal and choroidal vascular changes in coronary heart disease: an optical coherence tomography angiography study.

Biomedical Optics Express, 2019
To reveal the association between retinal microvasculature changes and coronary heart disease (CHD), we assessed the full retinal thicknesses of eight areas, the vessel density of four layers (consisting of nine areas) and the flow area in two layers ...

Non-invasive computed tomography coronary angiography as a gatekeeper for invasive coronary angiography [PDF]

The International Journal of Cardiovascular Imaging, 2012
To determine the rate of subsequent invasive coronary angiography (ICA) and revascularization in relation to computed tomography coronary angiography (CTA) results. In addition, independent determinants of subsequent ICA and revascularization were evaluated. CTA studies were performed using a 64-row (n = 413) or 320-row (n = 224) multidetector scanner.

Influence of the arterial elastic component on the response to balloon angioplasty in femoral arteries of a healthy porcine model

Animal Models and Experimental Medicine, EarlyView.
This study evaluates the role of elastin in vascular response 28 days after balloon angioplasty using uncoated and paclitaxel‐coated balloons in a healthy porcine model. The results show higher elastin content in external femoral arteries, which is inversely correlated with vascular injury, inflammation, smooth muscle cell loss, proteoglycan and fibrin

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis

, 2017
In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical ...
