Computational Fluid Dynamics facilitates in the quantitative analysis of haemodynamic processes of in vivo cardiovascular systems. The objective of the present study is to examine the effects of different branching angles of diseased renal arteries with respect to the abdominal aorta on its flow characteristics. Secondly, simulation of normal renal arteries at similar branching angles were also done as a baseline for comparison to comprehend if geometry played a role in the endothelial proliferation in renal artery stenosis. Idealistic renal artery models generated from the digital image of computerized tomography scan were used, with bifurcation angles at the junction ranging from 30° to 90° at successive intervals of 15°. Virtual stenosis of a degree below and above 80% by diameter were generated on the right and left renal artery respectively. The models were discretized using a hybrid polyhedral mesh. Parameters such as time-averaged velocity, time-averaged wall shear stress, pressure difference and fractional flow reserve were used to analyse the flow characteristics. Stenosed renal arteries with higher angulation was found to have larger flow recirculation zones, higher pressure gradient near the Ostia and was observed to experience greater amounts of shear stress at the region of stenosis. For the same degree of stenosis (above 80%), the blockage tended to increase from 18% to 25%, as the angle increased. The effect of angulation was observed to alter the flow characteristics significantly in the stenosed arteries. Critically stenosed (above 80%) renal arteries at a bifurcation angle above 45° showed signs of ischemia.

Fluid-Structure Interaction in Problems of Patient Specific Transcatheter Aortic Valve Implantation with and Without Paravalvular Leakage Complication Reviewed International journal

Basri A.A., Zuber M., Basri E.I., Zakaria M.S., Aziz A.F.A., Tamagawa M., Ahmad K.A.

Fluid Dynamics and Materials Processing 17 ( 3 ) 531 - 553 2021.01

Language：English Publishing type：Research paper (scientific journal)

Paravalvular Leakage (PVL) has been recognized as one of the most dangerous complications in relation to Transcathether Aortic Valve Implantation (TAVI) activities. However, data available in the literature about Fluid Structure Interaction (FSI) for this specific problem are relatively limited. In the present study, the fluid and structure responses of the hemodynamics along the patient aorta model and the aortic wall deformation are studied with the aid of numerical simulation taking into account PVL and 100% TAVI valve opening. In particular, the aorta without valve (AWoV) is assumed as the normal condition, whereas an aorta with TAVI 26 mm for 100% Geometrical Orifice Area (GOA) is considered as the patient aorta with PVL complication. A 3D patient-specific aorta model is elaborated using the MIMICS software. Implantation of the identical TAVI valve of Edward SAPIEN XT 26 (Edwards Lifes ciences, Irvine, California) is considered. An undersized 26 mm TAVI valve with 100% valve opening is selected to mimic the presence of PVL at the aortic annulus. The present research indicates that the existence of PVL can increase the blood velocity, pressure drop and WSS in comparison to normal conditions, thereby paving the way to the development of recirculation flow, thrombus formation, aorta wall collapse, aortic rupture and damage of endothelium.
