7) MODELING EMBRYONIC HEART DEVELOPMENT
Congenital heart diseases affect one percent of newborn babies and babies who are lost in the prenatal period, and the malformation of the circulatory system is responsible for 10 percent of stillbirths.
To give scientists new insight into the developing heart, math biologist Laura Miller, an assistant professor of mathematics at the University of North Carolina, along with mechanical engineer Arvind Santhanakrishnan and graduate student Anil Shenoy, constructed several dynamically scaled models of the embryonic heart within rigid plexiglass walls. The models represent the morphologies of different stages in heart development, and provide insight into the flow within the developing heart. Corresponding numerical simulations by Miller couple the electrophysiology to the flow patterns within a beating heart.
These physical and numerical models will help scientists gain a better understanding of the relationship between the fluid dynamics, electrophysiology, and biochemistry of the embryonic heart, which may allow doctors to detec
