Patency of the false lumen in chronic aortic dissection (AD) is associated with aortic dilation and long-term aortic events. However, predictors of adverse outcomes in this population are limited. The aim of this study was to evaluate the relationship between aortic growth rate and false lumen flow dynamics and biomechanics in patients with chronic, patent AD. [...]

Abnormal fluid dynamics at the ascending aorta may be at the origin of aortic aneurysms. This study was aimed at comparing the performance of computational fluid dynamics (CFD) and fluid-structure interaction (FSI) simulations against four-dimensional (4D) flow magnetic resonance imaging (MRI) data; and to assess the capacity of advanced fluid dynamics markers to stratify aneurysm progression risk.

Diseases of the descending aorta have emerged as a clinical issue in Marfan syndrome following improvements in proximal aorta surgical treatment and the consequent increase in life expectancy. Although a role for hemodynamic alterations in the etiology of descending aorta disease in Marfan patients has been suggested, whether flow characteristics may be useful as early markers remains to be determined.

262 p, 10.9 MB Predictores biomecánicos de dilatación en aorta ascendente en población con válvula aórtica bicúspide mediante resonancia magnética 4D flow / Dux-Santoy, Lydia ; Evangelista Masip, Arturo, dir. ; Rodríguez Palomares, José Fernando, dir. ; García Dorado, D., dir. ; Universitat Autònoma de Barcelona. Departament de Medicina
Antecedentes: Los diferentes fenotipos de fusión -derecho-izquierdo (RL) o derecho-no coronárico (RN)- de la válvula aórtica bicúspide (VAB) se asocian con distintos morfotipos de dilatación. La dilatación se ha relacionado con alteraciones en la tensión de corte (wall shear stress, WSS) secundarias a un diferente comportamiento del flujo en VAB, aunque algunos estudios sostienen que podría verse favorecida por un daño biomecánico intrínseco en la pared aórtica. [...]
Background: Different cusp-fusion bicuspid aortic valve (BAV) phenotypes -right-left (RL) or right-non-coronary (RN)- are associated with different dilation morphotypes. Aortic dilation has been related to alterations in wall shear stress (WSS) secondary to a different flow behavior in BAV, although some studies argue that it could be favored by an intrinsic biomechanical damage in the aortic wall of these patients.
