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

open access: yesJournal 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.

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 ...

Use of the instantaneous wave-free ratio or fractional flow reserve in PCI [PDF]

open access: yes, 2017
BACKGROUND: Coronary revascularization guided by fractional flow reserve (FFR) is associated with better patient outcomes after the procedure than revascularization guided by angiography alone.

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.

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.

Human coronary vessels: distribution of cholinergic nerve fibres and age-related changes [PDF]

open access: yes
Background. Cholinergic nerve fibres were studied in the human coronary vascular tree by means of acetylcholinesterase staining and choline acetyltransferase activities on autopsy samples of coronary vessels (arteries, veins, and micro-vessels ...

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.
