Clearly, This Heart Beats Strong

Researchers at Rice University and Japan's Waseda University have developed a model that simulates the flow of blood through the heart.

The model of a working ventricle-valve-aorta provides a detailed view of how the ventricle fills with blood, how quickly the three-leaf valve opens to relieve the pressure, and the flow of blood as it pushes through.

Said Rice's Tayfun Tezduyar, "This is a computational technology that no one else in the world currently has with this level of accuracy near the leaflet surfaces."

Tezduyar explained, "Modeling three-leaflet valves that touch each other, fully close off blood flow and then open again, and doing that with accurate representation of the near-leaflet flow patterns, is a new and challenging class of problems in fluid mechanics."

Tezduyar said the research could help doctors evaluate replacement valves for patients with heart disease.
