Image-based immersed boundary model of the aortic root [PDF]

open access: yesarXiv, 2017
Each year, approximately 300,000 heart valve repair or replacement procedures are performed worldwide, including approximately 70,000 aortic valve replacement surgeries in the United States alone. This paper describes progress in constructing anatomically and physiologically realistic immersed boundary (IB) models of the dynamics of the aortic root and

Fluid dynamics of aortic root dilation in Marfan syndrome [PDF]

open access: yesJournal of Biomechanics, 47, (2014) 3120-3128, 2014
Aortic root dilation and propensity to dissection are typical manifestations of the Marfan Syndrome (MS), a genetic defect leading to the degeneration of the elastic fibres. Dilation affects the structure of the flow and, in turn, altered flow may play a role in vessel dilation, generation of aneurysms, and dissection.

3D Printing-Assisted Energy Loss Testing of Artificial Aortic Heart Valves [PDF]

open access: yesarXiv, 2019
With the development of additive manufacturing, 3D printing technology has become more common nowadays. We designed and 3D printed a cost-effective liquid fluid pressure measurement device that can convert liquid pressure to air pressure. Air pressure was measured by a low-cost manometer in this study.
