Surgical Treatment for Left Main Coronary Atresia with Significant Mitral Regurgitation in a 1-Year-Old Child

Journal of Chest Surgery, 2021
Congenital atresia of the left main coronary artery (LMCA) is an extremely rare coronary anomaly that necessitates surgical correction. Patients with LMCA atresia may have various clinical symptoms, which are determined by the degree of collateral ...

Absence of Both Right and Left Main Coronary in a COVID Survivor

Diagnostics, 2021
The prevalence of isolated right coronary artery (RCA) absence ranges from 0.014% to 0.066% in the general population, but its combination with an absent left main (dual ostium left anterior descending [LAD] and super-dominant left circumflex [LCx]) has ...

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.

Congenital Absence of the Left Circumflex Artery Presenting With Inferoposterior Wall Myocardial Infarction Due to Stenosis of the Super Dominant Right Coronary Artery: A Rare Case

Cureus, 2023
The primary coronary arteries are the right coronary artery (RCA), the left main coronary artery (LMCA), which bifurcate into the left anterior descending artery (LAD), and the left circumflex artery (LCX), arising from the right coronary sinus and left ...

Point Transformer For Coronary Artery Labeling [PDF]

arXiv, 2023
Coronary CT angiography (CCTA) scans are widely used for diagnosis of coronary artery diseases. An accurate and automatic vessel labeling algorithm for CCTA analysis can significantly improve the diagnostic efficiency and reduce the clinicians'manual efforts.

YOLO-Angio: An Algorithm for Coronary Anatomy Segmentation [PDF]

arXiv, 2023
Coronary angiography remains the gold standard for diagnosis of coronary artery disease, the most common cause of death worldwide. While this procedure is performed more than 2 million times annually, there remain few methods for fast and accurate automated measurement of disease and localization of coronary anatomy.

PERSISTENT LEFT SUPERIOR VENA CAVA: A DECEPTIVE ANOMALY

Journal of Cancer and Allied Specialties, 2019
Persistent left superior vena cava (SVC) is a rare but vital congenital anomaly of the thoracic venous system. It is the persistence of vessel that normally regresses during early foetal life.

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

arXiv, 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 ...
