Multiaxial pulsatile dynamics of the thoracic aorta and impact of thoracic endovascular repair

European Journal of Radiology Open, 2021
Purpose: The thoracic aorta is a highly mobile organ whose dynamics are altered by thoracic endovascular aorta repair (TEVAR). The aim of this study was to quantify cardiac pulsatility-induced multi-axial deformation of the thoracic aorta before and ...

Papillary Fibroelastoma of the Ascending Aorta [PDF]

Journal of Investigative Medicine High Impact Case Reports, 2019
Papillary fibroelastomas are rare benign primary cardiac tumors. They are typically found on valvular surfaces, most commonly, the aortic valve. In this article, we report a case of papillary fibroelastoma arising from the sinotubular junction of the ascending aorta, a rare and unusual site causing an embolic stroke.

P.53 Ascending Aorta Diameter and Pulse Wave Velocity are Increased and Local Hemodynamic is Disrupted in Patients with Blunt Traumatic Thoracic Aortic Injury Treated by TEVAR

Artery Research, 2020
Background: Thoracic endovascular aortic repair (TEVAR) is becoming the preferred treatment option to repair the proximal descending aorta after rupture following blunt traumatic injury. However, hemodynamic and mechanic implications of this intervention

Utility of four-dimensional computed tomography angiography for evaluating the mobility of a thrombus in the ascending aorta

Radiology Case Reports, 2020
Four-dimensional computed tomography has been used to evaluate moving structures and is a useful method to diagnose cardiovascular diseases. We report a case of cerebral infarction due to the thrombus in the ascending aorta, and utilized 4-dimensional ...

Biomechanical properties of the aortic root are distinct from those of the ascending aorta in both normal and aneurysmal statesCentral MessagePerspective

JTCVS Open, 2023
Background: Although aneurysms of the ascending aorta and the aortic root are treated similarly in clinical guidelines, how biomechanical properties differ between these 2 segments of aorta is poorly defined.
