Pathogenesis of Single Right Coronary Artery and Pulmonic Stenosis in English Bulldogs [PDF]
, 2001 English Bulldogs are the most common breed to have pulmonic stenosis. Previous studies showed that this congenital heart abnormality in Bulldogs frequently is caused by a circumpulmonary left coronary artery originating from a single right coronary ...

3D Fusion between Fluoroscopy Angiograms and SPECT Myocardial Perfusion Images to Guide Percutaneous Coronary Intervention [PDF]
arXiv, 2020 Background. Percutaneous coronary intervention(PCI) in stable coronary artery disease(CAD) is commonly triggered by abnormal myocardial perfusion imaging(MPI). However, due to the possibilities of multivessel disease and variability of coronary artery perfusion distribution, opportunity exists to better align anatomic stenosis with perfusion ...

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis [PDF]
, 2017 In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical practice.

CathAI: Fully Automated Interpretation of Coronary Angiograms Using Neural Networks [PDF]
arXiv, 2021 Coronary heart disease (CHD) is the leading cause of adult death in the United States and worldwide, and for which the coronary angiography procedure is the primary gateway for diagnosis and clinical management decisions. The standard-of-care for interpretation of coronary angiograms depends upon ad-hoc visual assessment by the physician operator ...

Coronary-Cameral Fistula with Angina Pectoris [PDF]
, 2010 Coronary-cameral fistula (CCF) is an anomalous connection between a coronary artery and cardiac chamber. Most of CCFs are discovered incidentally during angiographic evaluation for coronary vascular disorder. We report a case of CCF with angina pectoris.

Post-processing of coronary and myocardial spatial data [PDF]
arXiv, 2022 Numerical simulations of real-world phenomena require a computational scheme and a computational domain. In the context of haemodynamics, the computational domain is the blood vessel network through which blood flows. Such networks contain millions of vessels that are joined in series and in parallel.

Hyperdominant left anterior descending artery continuing across left ventricular apex as posterior descending artery coexistent with aortic stenosis [PDF]
, 2007 We describe, in a 61 year old man, with coexistent aortic stenosis, the anomalous origin of posterior descending artery (PDA) from a stenotic left anterior descending (LAD) artery, as its continuation across the left ventricular apex, in the presence of ...

Unexpected Dual Left Anterior Descending Artery as a Source of Percutaneous Coronary Revascularization Failure. [PDF]
, 2016 Dual left anterior descending artery (LAD) is rare. A 61-year-old patient was referred because of angina and a positive stress test. Coronary angiography revealed a short LAD originating from the left main coronary artery.

NeCA: 3D Coronary Artery Tree Reconstruction from Two 2D Projections via Neural Implicit Representation [PDF]
Bioengineering 2024, 11(12), 1227Cardiovascular diseases (CVDs) are the most common health threats worldwide. 2D X-ray invasive coronary angiography (ICA) remains the most widely adopted imaging modality for CVD assessment during real-time cardiac interventions. However, it is often difficult for cardiologists to interpret the 3D geometry of coronary vessels based on 2D planes ...

Automated Detection of Coronary Artery Stenosis in X-ray Angiography using Deep Neural Networks [PDF]
arXiv, 2021 Coronary artery disease leading up to stenosis, the partial or total blocking of coronary arteries, is a severe condition that affects millions of patients each year. Automated identification and classification of stenosis severity from minimally invasive procedures would be of great clinical value, but existing methods do not match the accuracy of ...
