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

open access: yesarXiv, 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.

The Role of Collateral Circulation in Preserving Myocardial Function

open access: yesBiomolecules & Biomedicine, 2006
The coronary collateral circulation is an alternative source of blood supply to the myocardium jeopardized by the failure of the original stenotic or occluded vessel to provide adequate blood flow to this region. One hundred coronary angiograms and left

Reprogramming the myocardial infarction microenvironment with melanin-based composite nanomedicines in mice

open access: yesNature Communications
Myocardial infarction (MI) has a 5-year mortality rate of more than 50% due to the lack of effective treatments. Interactions between cardiomyocytes and the MI microenvironment (MIM) can determine the progression and fate of infarcted myocardial tissue ...
