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

Fluid dynamics of heart valves during atrial fibrillation: a lumped parameter-based approach [PDF]
, 2015 Atrial fibrillation (AF) consequences on the heart valve dynamics are usually studied along with a valvular disfunction or disease, since in medical monitoring the two pathologies are often concomitant. Aim of the present work is to study, through a stochastic lumped-parameter approach, the basic fluid dynamics variations of heart valves, when only ...

Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]
arXiv, 2022 Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.
