Software subroutines for modeling cardiac pressure-volume relationship and coronary blood flow
Stanford researchers at the Taylor Lab have developed software subroutines that can be used together with the open source software system Simvascular to improve the simulation of blood flow in modeling coronary arteries. These subroutines implement lumped parameter heart models and coronary boundary condition models to three-dimensional finite element models of the aorta and coronary arteries. These methods have been demonstrated to yield physiologically realistic pressure and flow waveforms in coronary circulation and can be used for purposes of understanding mechanisms of coronary artery disease, designing coronary devices or planning interventions.
