Coarctation of the Aorta [PDF]
BMJ, 1956 This report summarises our experience with 16 cases of coarctation of the aorta. Clinical and radiological aspects are briefly reviewed. Theimportance of angiocardiography in demonstrating the site and length of the stenosed aortic segment is indicated. The complications of the untreated condition and the indications for surgery are outlined.

Pathology of the Aorta and Aorta as Homograft [PDF]
Journal of Cardiovascular Development and Disease, 2021 The aorta is not a rigid tube, it is an “organ” with lamellar units, consisting of elastic fibers, extracellular matrix and smooth muscle cells in between as parenchyma. Several diseases may occur in the natural history of the aorta, requiring replacement of both semilunar cusps and ascending aorta.

Mathematical modeling of shear-activated targeted nanoparticle drug delivery for the treatment of aortic diseases [PDF]
Biomechanics and Modeling in Mechanobiology (2021), 2021 The human aorta is a high-risk area for vascular diseases, which are commonly restored by thoracic endovascular aortic repair. In this paper, we report a promising shear-activated targeted nanoparticle drug delivery strategy to assist in the treatment of coarctation of the aorta and aortic aneurysm.

Hemodynamic effects of stent-graft introducer sheath during thoracic endovascular aortic repair [PDF]
Biomechanics and Modeling in Mechanobiology (2022), 2021 Thoracic endovascular aortic repair (TEVAR) has become the standard treatment of a variety of aortic pathologies. The objective of this study is to evaluate the hemodynamic effects of stent-graft introducer sheath during TEVAR. Three idealized representative diseased aortas of aortic aneurysm, coarctation of the aorta, and aortic dissection were ...

Automatic Aorta Segmentation with Heavily Augmented, High-Resolution 3-D ResUNet: Contribution to the SEG.A Challenge [PDF]
MICCAI 2023, Segmentation of the Aorta Challenge, 2023 Automatic aorta segmentation from 3-D medical volumes is an important yet difficult task. Several factors make the problem challenging, e.g. the possibility of aortic dissection or the difficulty with segmenting and annotating the small branches. This work presents a contribution by the MedGIFT team to the SEG.A challenge organized during the MICCAI ...

Classification of Pressure Gradient of Human Common Carotid Artery and Ascending Aorta on the Basis of Age and Gender [PDF]
International Journal of computer Applications, Volume 145, No.1,
July 2016, 2017 The current work is done to see which artery has more chance of having cardiovascular diseases by measuring value of pressure gradient in the common carotid artery (CCA) and ascending aorta according to age and gender. Pressure gradient is determined in the CCA and ascending aorta of presumed healthy volunteers, having age between 10 and 60 years.

Editorial Coarctation of the aorta [PDF]
Archives of Medical Science, 2012 Ding et al. report in the current number of the AMS [1] a 12 year old patient with abdominal coarctation of the aorta above the renal arteries treated successfully with percutanous transluminal angioplasty. This report is a useful reminder that hypertension maybe the sole manifestation of aortic coarctation that has an estimated incidence of 1 in 2500 ...

Automatic Segmentation of Thoracic Aorta Segments in Low-Dose Chest CT [PDF]
SPIE Medical Imaging, 2018, vol. 10574, pp. 105741S, 2018 Morphological analysis and identification of pathologies in the aorta are important for cardiovascular diagnosis and risk assessment in patients. Manual annotation is time-consuming and cumbersome in CT scans acquired without contrast enhancement and with low radiation dose.
