| description | The research and development of better prosthetic heart valves need better knowledge of their effect on the blood flow, therefore a new design will need hemodinamics studies. This paper presents a numerical model based on finite element analysis, developed and validated for bileaflet prosthetic heart valve. This model assumes laminar and steady-state flow, Newtonian and incompressible fluid and isothermical system. The model was developed to be used in the design of trileaflet prosthetic heart valves, to be presented in a second paper. |

Prótesis valvular cardíacaLa investigación y desarrollo de modelos de mejores prótesis valvulares necesitan de un mejor conocimiento de cómo afectan el flujo sanguíneo, por lo tanto para el diseño de nuevos modelos es imprescindible la realización de estudios hemodinámicos. En este trabajo se presenta un modelo numérico basado en análisis por elementos finitos, desarrollado y validado para prótesis bivalvas. El modelo considera flujo en estado estacionario y laminar, considerando a la sangre como un fluido Newtoniano e incompresible. El sistema se considera isotérmico. El modelo fue planteado para su aplicación en el diseño de prótesis trivalvas, cuya descripción se presenta por separado.
