Simultaneous regulation of hemodynamic and anesthetic states: a simulation study.

abstract：:Numerical models of the mitral valve have been used to elucidate mitral valve function and mechanics. These models have evolved from simple two-dimensional approximations to complex three-dimensional fully coupled fluid structure interaction models. However, to date these models lack direct one-to-one experimental val...
