Single left coronary artery with the right coronary artery arising from the mid-portion of the left anterior descending artery. Diagnosis with MDCT.

Journal of the Belgian Society of Radiology, 2012
Single coronary artery is a very rare entity.We describe a very unusual subtype of this anomaly in which the right coronary artery arises from the mid-portion of the left anterior descending artery.

An Endothelial Contribution to Coronary Vessels [PDF]

Cell, 2012
Despite the profound impact of coronary artery disease on human health, the origins of the coronary blood vessels are poorly understood. Wu et al. use imaging and genetic techniques to show that the endocardium contributes to the coronary vessels and that the coronary arteries and veins have multilineage origins.

Compliant vascular models 3D printed with the Stratasys J750: a direct characterization of model distensibility using intravascular ultrasound

3D Printing in Medicine, 2021
Purpose The purpose of this study is to evaluate biomechanical accuracy of 3D printed anatomical vessels using a material jetting printer (J750, Stratasys, Rehovot, Israel) by measuring distensibility via intravascular ultrasound.

Development of Coronary Vessels

The FASEB Journal, 2004
Publisher Summary This chapter discusses the development in coronary vessels. Formation of the coronary vessels occurs through an epithelial-to-mesenchymal transformation of proepicardial cells, followed by vasculogenesis in the subepicardial layer, assembly and remodeling of a primitive coronary plexus, and recruitment of a smooth-muscle coating ...

Vesselness-guided Active Contour: A Coronary Vessel Extraction Method

Journal of Medical Signals & Sensors, 2014
Vessel extraction is a critical task in clinical practice. In this paper, we propose a new approach for vessel extraction using an active contour model by defining a novel vesselness-based term, based on accurate analysis of the vessel structure in the image.

Changes in Immune‐Inflammation Status and Acute Ischemic Stroke Prognosis in Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Inflammation is a critical risk factor for poor outcomes in cerebral infarction. Prior studies focused primarily on baseline inflammation status, neglecting dynamic longitudinal changes. We try to investigate the association between immune‐inflammation status alterations and stroke prognosis, and evaluated three systemic biomarkers'

Relationship between epicardial fat volume on cardiac CT and atherosclerosis severity in three-vessel coronary artery disease: a single-center cross-sectional study

BMC Cardiovascular Disorders, 2022
Background The ideal treatment strategy for stable three-vessel coronary artery disease (CAD) patients are difficult to determine and for patients undergoing conservative treatment, imaging evidence of coronary atherosclerotic severity progression ...

Identification of Flow-Limiting Coronary Stenosis With PCS: A New Cost-Effective Index Derived From the Product of Corrected TIMI Frame Count and Percent Diameter Stenosis

Frontiers in Cardiovascular Medicine, 2021
Background: Identifying functional coronary stenosis with simple and cost-effective methods during invasive coronary angiography is still challenging. Corrected TIMI frame count (CTFC) is considered to be the frame count velocity of coronary blood flow ...

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...
