Computational fluid dynamics simulation of the right subclavian artery cannulation

Abstract

Right subclavian artery cannulation was cerebroprotective, especially on the right side.

Impact of turbulent blood flow in the aortic root on de novo aortic insufficiency during continuous‐flow left ventricular‐assist device support

“…Our methods of computational analyses have been previously described. [7][8][9][10][18][19][20] Data for the analyses were acquired by electrocardiogram-gated 320-slice CT imaging. The image data in Digital Imaging and Communications in Medicine format were rendered into three-dimensional patient-specific geometries, including the aorta, coronary arteries, cervical branch arteries, and LVAD outflow graft using a dedicated software (AZE, Tokyo, Japan).…”

“…5 Computational fluid dynamics (CFD) could help visualize and evaluate the blood flow, flow velocity, wall shear stress, and other fluid dynamic parameters in the three-dimensional aorta. [7][8][9][10] However, previous studies using CFD have only reported blood flow analysis in the ascending aorta without the aortic root because of the complex anatomy of the aortic root and its components such as the aortic valve, coronary arteries, and Valsalva sinus. [11][12][13][14][15] To evaluate the three-dimensional blood flow in the aortic root, three-dimensional patient-specific geometries with accurate anatomy of the aortic root were reproduced using electrocardiogram-gated 320-slice computed tomographic (CT) images.…”

“…Although blood flow analysis using vector flow mapping with two‐dimensional echocardiographic images was previously reported, the actual blood flow and shear stress in the three‐dimensional aortic root is unknown .

Computerized virtual surgery based on computational fluid dynamics simulation for planning coronary revascularization with aortic root replacement in adult congenital heart disease: a case report

“…Therefore, we performed computerized virtual surgery based on CFD combined with 3D CG. The CFD method was based on our previous validation studies [4,5]. We used the data obtained from thin-slice, early-phase, enhanced multidetector-row CT imaging.…”

Commentary: Always do right

“…Their report consequently confirmed that the incidence rate of right-hemisphere stroke was significantly lower in the right axillary artery cannulation group. Numata and colleagues 4 reported that the right subclavian artery cannulation was cerebroprotective with the use of computational fluid dynamics simulation. They showed that a retrograde flow of the brachiocephalic artery and an antegrade flow of the right common carotid artery were produced from the blood streamline from the right subclavian artery throughout the cardiac cycle.…”
