Single Coronary Artery with Anomalous Rising of the Right Coronary Artery: A Rare Coronary Anomaly Diagnosed by 256-Multidetector Computed Tomography [PDF]

, 2011
Herein we report the diagnostic potential of cardiac computed tomography (cCT) to delineate the origin and course of an anomalous right coronary artery (RCA) originating from the midpart of the left anterior descended artery (LAD) in an adult with no ...

Automated Deep Learning Analysis of Angiography Video Sequences for Coronary Artery Disease [PDF]

arXiv, 2021
The evaluation of obstructions (stenosis) in coronary arteries is currently done by a physician's visual assessment of coronary angiography video sequences. It is laborious, and can be susceptible to interobserver variation. Prior studies have attempted to automate this process, but few have demonstrated an integrated suite of algorithms for the end-to-

Rare case of coronary to pulmonary vein fistula with coronary steal phenomenon [PDF]

, 2014
Coronary artery fistulas are abnormal connections between coronary artery territories and cardiac chambers or major vessels, most of them are congenital.

Hyper Association Graph Matching with Uncertainty Quantification for Coronary Artery Semantic Labeling [PDF]

arXiv, 2023
Coronary artery disease (CAD) is one of the primary causes leading to death worldwide. Accurate extraction of individual arterial branches on invasive coronary angiograms (ICA) is important for stenosis detection and CAD diagnosis. However, deep learning-based models face challenges in generating semantic segmentation for coronary arteries due to the ...

Assessment of congenital coronary artery fistulas by transesophageal color Doppler echocardiography [PDF]

, 2002
PURPOSE: Coronary angiography is the gold standard for imaging the coronary tree, but the relation of coronary artery fistulas to other structures, and their origin and course, may not be apparent.

Combined analysis of coronary arteries and the left ventricular myocardium in cardiac CT angiography for detection of patients with functionally significant stenosis [PDF]

arXiv, 2019
Treatment of patients with obstructive coronary artery disease is guided by the functional significance of a coronary artery stenosis. Fractional flow reserve (FFR), measured during invasive coronary angiography (ICA), is considered the gold standard to define the functional significance of a coronary stenosis.

Aortic Valve Replacement in Anomalous Aortic Origin of Right Coronary Artery [PDF]

, 2015
A 75-year-old man with severe aortic regurgitation was referred to our department for surgery. Coronary angiography revealed 75% stenosis at left coronary artery( LAD) and a normally positioned left coronary artery.

Segmentation and Vascular Vectorization for Coronary Artery by Geometry-based Cascaded Neural Network [PDF]

arXiv, 2023
Segmentation of the coronary artery is an important task for the quantitative analysis of coronary computed tomography angiography (CCTA) images and is being stimulated by the field of deep learning. However, the complex structures with tiny and narrow branches of the coronary artery bring it a great challenge.

Rotational arherectomy in the distal left anterior descending coronary artery through an internal mammary artery graft. [PDF]

, 2006
We report the case of a 53-year-old white man who began complaining of dyspnoea and angina 19 months after coronary artery bypass graft surgery. Coronary angiography revealed the presence of a long and critical stenosis in the native left anterior ...

Computational fluid dynamics analysis of the effect of simulated plaques in the left coronary artery: A preliminary study [PDF]

, 2011
Background: Atherosclerosis is the most common cause of coronary artery disease which is formed by plaque presence inside the artery wall leading to blockage of the blood supply to the heart muscle.
