Hydrodynamics of Aortic Blood Flow.
• The peculiarities of the arterial circulation, including pulsatile flow in tubes with distensible walls and multiple branchings, make it difficult to apply classical hydrodynamic principles to the aortic blood flow without direct experimental verification. An example of the present confusion regarding fundamental concepts is the question of mixing in the aortic root. The generally accepted vi...
متن کاملAortic Stiffening, Aortic Blood Flow Reversal, and Renal Blood Flow.
N ormal arterial aging is characterized by arterial enlargement , wall thickening, and stiffening, which predominates at large arteries. 1 Patients with chronic kidney disease (CKD) have an early vascular aging, 2 characterized by an accelerated arterial enlargement and stiffening, which occurs in parallel with the decline in glomerular filtration rate (GFR). 3 The relationships between central...
متن کاملMultiscale modeling of nanocarrier (NC) hydrodynamics in blood flow
Nanocarrier (NC) transport in blood vessels involves hydrodynamic and thermodynamic interactions, which collectively dictate efficacy in targeted drug delivery applications. We investigate two important transport effects of (1) the effect of blood particulates in defining the hydrodynamic fields in simple and complex vascular geometries, and (2) hydrodynamic interactions for NCs of complex shapes.
متن کاملEffects of aortic irregularities on blood flow
Anatomic aortic anomalies are seen in many medical conditions and are known to cause disturbances in blood flow. Turner syndrome (TS) is a genetic disorder occurring only in females where cardiovascular anomalies, particularly of the aorta, are frequently encountered. In this study, numerical simulations are applied to investigate the flow characteristics in four TS patient- related aortic arch...
متن کاملFour-dimensional aortic blood flow patterns in thoracic aortic grafts.
Time-resolved cardiac gated three-directional velocity data obtained with magnetic resonance velocity-encoded phase contrast sequences were used to study blood flow patterns in thoracic aortic grafts. Twelve patients were studied, 6 with traumatic descending aortic pseudoaneurysms, 3 with atherosclerotic aneurysms, and 3 with dissecting aneurysms. All grafts had an inflow jet; outflow jet; and/...
