Abstract It is well known that local fluid dynamic phenomena are the main factors affecting the failure of aorto-coronary bypass procedures. With the aim of investigating the influence of bypass geometrical parameters on the fluid dynamics around the anastomosis, a two-dimensional finite element model of a stenosed coronary artery with an aorto-coronary bypass has been developed. The geometrical parameters on which the study focused were the degree of coronary stenosis, the bypass diameter and the bypass angle. The fluid dynamic equations have been solved using the finite element method. The results show the development of a recirculation area immediately downstream of the anastomosis and its relationship with the investigated parameters. In particular, the magnitude of the recirculation increases with the bypass angle, the bypass diameter and the degree of coronary stenosis.
