AGFA-Net: Attention-Guided and Feature-Aggregated Network for Coronary Artery Segmentation using Computed Tomography Angiography [PDF]
arXivCoronary artery disease (CAD) remains a prevalent cardiovascular condition, posing significant health risks worldwide. This pathology, characterized by plaque accumulation in coronary artery walls, leads to myocardial ischemia and various symptoms, including chest pain and shortness of breath.

Direct Quantification for Coronary Artery Stenosis Using Multiview Learning [PDF]
arXiv, 2019 The quantification of the coronary artery stenosis is of significant clinical importance in coronary artery disease diagnosis and intervention treatment. It aims to quantify the morphological indices of the coronary artery lesions such as minimum lumen diameter, reference vessel diameter, lesion length, and these indices are the reference of the ...

DeepCA: Deep Learning-based 3D Coronary Artery Tree Reconstruction from Two 2D Non-simultaneous X-ray Angiography Projections [PDF]
arXivCardiovascular diseases (CVDs) are the most common cause of death worldwide. Invasive x-ray coronary angiography (ICA) is one of the most important imaging modalities for the diagnosis of CVDs. ICA typically acquires only two 2D projections, which makes the 3D geometry of coronary vessels difficult to interpret, thus requiring 3D coronary artery tree ...

A topology-preserving three-stage framework for fully-connected coronary artery extraction [PDF]
arXivCoronary artery extraction is a crucial prerequisite for computer-aided diagnosis of coronary artery disease. Accurately extracting the complete coronary tree remains challenging due to several factors, including presence of thin distal vessels, tortuous topological structures, and insufficient contrast.

Atrial tachycardia treated by coil embolization of a giant coronary artery fistula
Revista Portuguesa de Cardiologia, 2014 Coronary artery fistulas are the second most frequently seen coronary anomaly following abnormalities of coronary artery origin and distribution. A coronary fistula is defined as a direct communication between a coronary artery and any cardiac chamber or

Giant Right Coronary Artery Aneurysm
JACC: Case Reports, 2020 Coronary artery aneurysms are rare conditions with potentially devastating consequences. We describe the case of an athletic 40-year-old woman who received a diagnosis of giant right coronary artery aneurysm while she was undergoing a work-up for lower ...

4D-CAT: Synthesis of 4D Coronary Artery Trees from Systole and Diastole [PDF]
arXivThe three-dimensional vascular model reconstructed from CT images is widely used in medical diagnosis. At different phases, the beating of the heart can cause deformation of vessels, resulting in different vascular imaging states and false positive diagnostic results. The 4D model can simulate a complete cardiac cycle.

Mitral Valve Repair and Anomalous Origin of Circumflex Artery
JACC: Case Reports, 2019 We describe a case of an adult patient with mitral valve regurgitation and the anomalous origin and course of the left circumflex coronary artery. Use of a ringless procedure or a microinvasive approach, such as transapical neochordae implantation, would
