Propagation-based phase-contrast synchrotron imaging of aortic dissection in mice : from individual elastic lamella to 3D analysis [PDF]

, 2018
In order to show the advantage and potential of propagation-based phase-contrast synchrotron imaging in vascular pathology research, we analyzed aortic medial ruptures in BAPN/AngII-infused mice, a mouse model for aortic dissection. Ascending and thoraco-

Challenging endovascular treatment of a thoracic saccular aneurysm in extensive coral reef aorta

Journal of Vascular Surgery Cases and Innovative Techniques, 2022
Coral reef aorta (CRA) is characterized by heavily calcified obstructive lesions in the aorta. Thoracic endovascular aortic repair (TEVAR) is an established, less invasive procedure for aortic diseases; however, aortic occlusive diseases are commonly ...

Single-Stage Open Repair of Extensive Arch and Descending Thoracic Aneurysm through Sternotomy: A Case Report

Journal of Chest Surgery, 2021
Extensive thoracic aortic disease involving the ascending aorta, the aortic arch, and the descending thoracic aorta may require multiple surgical and interventional managements, which impose a burden in terms of cumulative surgical trauma and the risk ...

Aortic and arterial mechanics [PDF]

Cardiovascular Mechanics, 2018, 2019
Knowledge of the mechanical properties of the aorta is essential as important concerns regarding the treatment of aortic pathologies, such as atherosclerosis, aneurysms and dissections, are fundamentally mechanobiological. A comprehensive review is presented in the current chapter. As the function of arteries is to carry blood to the peripheral organs,

Clinical Results for Cardiovascular Xenografts Treated With Novel Anticalcification Protocols

Artificial Organs, EarlyView.
This study demonstrates the safety, efficacy, and clinical performance of the tissue‐engineered Periborn bovine pericardial scaffold treated with our novel anticalcification protocols for surgical repair of a variety of cardiovascular diseases. The overall probability of freedom from Periborn‐related reoperation was 95.4% ± 3.2% at 9 years.

Including Aortic Valve Morphology in Computational Fluid Dynamics Simulations: Initial Findings and Application to Aortic Coarctation [PDF]

, 2012
Computational fluid dynamics (CFD) simulations quantifying thoracic aortic flow patterns have not included disturbances from the aortic valve (AoV). 80% of patients with aortic coarctation (CoA) have a bicuspid aortic valve (BAV) which may cause adverse ...

The efficacy of immediate bridging thoracic endovascular aortic repair for ruptured infected thoracic aortic aneurysms

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
Herein we describe four cases of ruptured infected thoracic aortic aneurysm. All patients underwent emergent thoracic endovascular aortic repair to stabilize hemodynamics.

Calibration of the mechanical boundary conditions for a patient-specific thoracic aorta model including the heart motion effect [PDF]

Volume: 70 Issue: 11, November 2023, IEEE Transaction on Biomedical Engineering
Objective: we propose a procedure for calibrating 4 parameters governing the mechanical boundary conditions (BCs) of a thoracic aorta (TA) model derived from one patient with ascending aortic aneurysm. The BCs reproduce the visco-elastic structural support provided by the soft tissue and the spine and allow for the inclusion of the heart motion effect.

Systemic Inflammatory Response and Severe Thrombocytopenia after Endovascular Thoracic Aortic Aneurysm Repair

Case Reports in Medicine, 2017
After Endovascular repair of thoracic aortic aneurysm, a systemic inflammatory response, named postimplantation syndrome, can develop. This syndrome is characterized by fever, leukocytosis, and elevated CRP plasma levels and its pathogenetic mechanisms ...
