Our objective was to design a new trileaflet aortic valve using computer-aided design (CAD). Quantification of aortic valve geometries is essential in understanding normal and pathological valvular function and eventually in the design of valves. We have designed a new tissue valve model to investigate its suitability in aortic valve replacement. Steps involved in three-dimensional CAD-based geometric modeling of a trileaflet aortic valve and the effects of different component dimensions on the mechanical behavior of valve are presented in this article. Conceptual designing of individual components was used to build the total geometric model. A new geometric model of a trileaflet aortic valve was designed. This may be of great interest to designers of new prosthetic heart valve models, as well as to surgeons involved in valve-sparing surgery.
我们的目标是使用计算机辅助设计（CAD）设计一种新型三叶式主动脉瓣。定量分析主动脉瓣几何形状对于理解正常和病理瓣膜功能至关重要，最终对于瓣膜设计也至关重要。我们设计了一种新型组织瓣膜模型，以研究其在主动脉瓣置换中的适用性。本文介绍了基于三维 CAD 的三叶式主动脉瓣几何建模的步骤，以及不同组件尺寸对瓣膜机械性能的影响。使用单个组件的概念设计来构建总几何模型。设计了一种新型三叶式主动脉瓣的几何模型。这对于新型人工心脏瓣膜模型的设计者以及参与瓣膜保留手术的外科医生可能都具有重要意义。
