3D Coronary Vessel Reconstruction from Bi-Plane Angiography using Graph Convolutional Networks [PDF]

open access: yesarXiv, 2023
X-ray coronary angiography (XCA) is used to assess coronary artery disease and provides valuable information on lesion morphology and severity. However, XCA images are 2D and therefore limit visualisation of the vessel. 3D reconstruction of coronary vessels is possible using multiple views, however lumen border detection in current software is ...

The haemodynamic effects of collateral donation to a chronic total occlusion : implications for patient management [PDF]

open access: yes, 2015
Physiological lesion assessment in the form of Fractional Flow Reserve (FFR) is now well established for the purpose of guiding multi-vessel revascularization.

Partial Vessels Annotation-based Coronary Artery Segmentation with Self-training and Prototype Learning [PDF]

open access: yesarXiv, 2023
Coronary artery segmentation on coronary-computed tomography angiography (CCTA) images is crucial for clinical use. Due to the expertise-required and labor-intensive annotation process, there is a growing demand for the relevant label-efficient learning algorithms.

Robust PCA Unrolling Network for Super-resolution Vessel Extraction in X-ray Coronary Angiography [PDF]

open access: yesarXiv, 2022
Although robust PCA has been increasingly adopted to extract vessels from X-ray coronary angiography (XCA) images, challenging problems such as inefficient vessel-sparsity modelling, noisy and dynamic background artefacts, and high computational cost still remain unsolved.

Implantation of paclitaxel-eluting stents in saphenous vein grafts: clinical and angiographic follow-up results from a multicentre study. [PDF]

open access: yes, 2006
Objective: To define the clinical and angiographic follow-up results after implantation of paclitaxel-eluting stents (PESs) in stenotic saphenous vein grafts (SVGs). Design: Prospective multicentre study. Comparison with a control group.

Vascular Development and Regeneration in the Mammalian Heart

open access: yesJournal of Cardiovascular Development and Disease, 2016
Cardiovascular diseases including coronary artery disease are the leading cause of death worldwide. Unraveling the developmental origin of coronary vessels could offer important therapeutic implications for treatment of cardiovascular diseases.

Coronary Circulation and Hemodynamics [PDF]

open access: yes, 2017
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygenrich blood to the myocardium are known as coronary arteries.

Extraction of Coronary Vessels in Fluoroscopic X-Ray Sequences Using Vessel Correspondence Optimization [PDF]

open access: yes, 2022
We present a method to extract coronary vessels from fluoroscopic x-ray sequences. Given the vessel structure for the source frame, vessel correspondence candidates in the subsequent frame are generated by a novel hierarchical search scheme to overcome the aperture problem.

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

open access: yesBMC 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 ...
