Coarctation of the Thoracic Aorta
The Annals of Thoracic Surgery, 1971 Abstract Operative resection is clearly the treatment of choice for coarctation of the thoracic aorta. The optimal time for elective repair appears to start at age 4 years. When coarctation must be dealt with in the first few months of life because of persisting congestive heart failure, there will be a significant mortality which is correlated with ...

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 ...

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.

Aneurysms of the thoracic aorta [PDF]
Thorax, 1971 Selected radiographs from 40 patients with thoracic aortic aneurysm serve to illustrate most of the radiographic features of this disease. Surgical techniques are outlined and were used to modify the natural course of the disease in 14 patients, with three postoperative deaths.

Fluid structure interaction: Insights into biomechanical implications of endograft after thoracic endovascular aortic repair [PDF]
Computers in Biology and Medicine (2021), 2021 Thoracic endovascular aortic repair (TEVAR) has developed to be the most effective treatment for aortic diseases. This study aims to evaluate the biomechanical implications of the implanted endograft after TEVAR. We present a novel image-based, patient-specific, fluid-structure computational framework.

A robust shape model for blood vessels analysis [PDF]
, 2023 The availability of digital twins for the cardiovascular system will enable insightful computational tools both for research and clinical practice. This, however, demands robust and well defined models and methods for the different steps involved in the process.

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.

Multiscale constitutive framework of 1D blood flow modeling: Asymptotic limits and numerical methods [PDF]
Multiscale Model. Simul. 21 (2023) 1237-1267, 2023 In this paper, a multiscale constitutive framework for one-dimensional blood flow modeling is presented and discussed. By analyzing the asymptotic limits of the proposed model, it is shown that different types of blood propagation phenomena in arteries and veins can be described through an appropriate choice of scaling parameters, which are related to ...

Thoracic Aorta: Anatomy and Pathology
Diagnostics, 2023 The aorta is the largest elastic artery in the human body and is classically divided into two anatomical segments, the thoracic and the abdominal aorta, separated by the diaphragm. The thoracic aorta includes the aortic root, the ascending aorta, the arch, and the descending aorta.
