Computational simulation of the pulmonary arteries and its role in the study of pediatric pulmonary hypertension

Abstract: The hemodynamic state of the pulmonary arteries is challenging to routinely measure in children due to the vascular circuit''s position in the lungs. The resulting relative scarcity of quantitative clinical diagnostic and prognostic information impairs management of diseases such as pulmonary hypertension, or high blood pressure of the pulmonary circuit, and invites new techniques of measurement. Here we examine recent applications of macro-scale computational mechanics methods for fluids and solids – traditionally used by engineers in the design and virtual testing of complex metal and composite structures – applied to study the pulmonary vasculature, both in healthy and diseased states. In four subject areas, we briefly outline advances in computational methodology and provide examples of clinical relevance. [Copyright &y& Elsevier]
