Patient-specific modeling of blood flow and pressure in human coronary arteries

HJ Kim, IE Vignon-Clementel, JS Coogan… - Annals of biomedical …, 2010 - Springer
Coronary flow is different from the flow in other parts of the arterial system because it is
influenced by the contraction and relaxation of the heart. To model coronary flow …
