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.

Robust semi-automated path extraction for visualising stenosis of the coronary arteries [PDF]

, 2008
Computed tomography angiography (CTA) is useful for diagnosing and planning treatment of heart disease. However, contrast agent in surrounding structures (such as the aorta and left ventricle) makes 3-D visualisation of the coronary arteries difficult ...

Perspectives in Microvascular Fluid Handling: Does the Distribution of Coagulation Factors in Human Myocardium Comply with Plasma Extravasation in Venular Coronary Segments? [PDF]

, 2010
Background: Heterogeneity of vascular permeability has been suggested for the coronary system. Whereas arteriolar and capillary segments are tight, plasma proteins pass readily into the interstitial space at venular sites.

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.

Underuse of coronary revascularization procedures in patients considered appropriate candidates for revascularization. [PDF]

, 2001
Background: Ratings by an expert panel of the appropriateness of treatments may offer better guidance for clinical practice than the variable decisions of individual clinicians, yet there have been no prospective studies of clinical outcomes. We compared

A polymer coated cicaprost-eluting stent increases neointima formation and impairs vessel function in the rabbit iliac artery [PDF]

, 2016
Drug-eluting stents have been successful in reducing in-stent restenosis but are not suitable for all lesion types and have been implicated in causing late stent thrombosis due to incomplete regeneration of the endothelial cell layer.

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 ...

Vessel tractography using an intensity based tensor model with branch detection [PDF]

, 2013
In this paper, we present a tubular structure seg- mentation method that utilizes a second order tensor constructed from directional intensity measurements, which is inspired from diffusion tensor image (DTI) modeling.
