hapln1a + cells guide coronary growth during heart morphogenesis and regeneration
Nature Communications, 2023 Although several tissues and chemokines orchestrate coronary formation, the guidance cues for coronary growth remain unclear. Here, we profile the juvenile zebrafish epicardium during coronary vascularization and identify hapln1a + cells enriched with ...

Reducing the X-ray radiation exposure frequency in cardio-angiography via deep-learning based video interpolation [PDF]
arXiv, 2020 Cardiac coronary angiography is a major technology to assist doctors during cardiac interventional surgeries. Under the exposure of X-ray radiation, doctors inject contrast agents through catheters to determine the position and status of coronary vessels in real time.

Microvascular coronary collateral vessels
КардиоСоматика, 2017 In normal human hearts, arterial collaterals are rare, but often develop during coronary disease. These collaterals can limit or even prevent myocardial infarction.

C-DARL: Contrastive diffusion adversarial representation learning for label-free blood vessel segmentation [PDF]
arXiv, 2023 Blood vessel segmentation in medical imaging is one of the essential steps for vascular disease diagnosis and interventional planning in a broad spectrum of clinical scenarios in image-based medicine and interventional medicine. Unfortunately, manual annotation of the vessel masks is challenging and resource-intensive due to subtle branches and complex

Robust semi-automated path extraction for visualising stenosis of the coronary arteries [PDF]
, 2008 Computed tomography angiography (CTA) is useful for diagnosing and planning treatment of heart disease. However, contrast agent in surrounding structures (such as the aorta and left ventricle) makes 3-D visualisation of the coronary arteries difficult ...

Serum low density lipoprotein receptor related protein-6 is a discriminator of occluded coronary artery assessed by coronary angiogram [PDF]
, 2019 Background: Human lipoprotein receptor-related protein -6 (LRP6) plays a role in the development of coronary artery disease. This study aimed to determine the serum level of the LRP6 in patients referred to the coronary angiogram taking into ...

Underuse of coronary revascularization procedures in patients considered appropriate candidates for revascularization. [PDF]
, 2001 Background: Ratings by an expert panel of the appropriateness of treatments may offer better guidance for clinical practice than the variable decisions of individual clinicians, yet there have been no prospective studies of clinical outcomes. We compared
