Abstract

In-stent restenosis ails many patients who have undergone stenting. When the stented artery is a bifurcation, the intervention is especially critical because of the complex stent geometry involved in these structures. Computational Fluid Dynamics (CFD) has demonstrated to be an effective approach when modelling blood flow behavior and understanding the mechanisms that underlie in-stent restenosis. These CFD models, however, require validation through experimental data in order to be reliable. It is with this purpose in mind that we performed Particle Image Velocimetry (PIV) measurements of velocity fields within flows through a simplified coronary bifurcation. Although the flow in this simplified bifurcation differs from the actual blood flow, it emulates the main fluid dynamic mechanisms found in hemodynamic flow. Experimental measurements for several stenting techniques under steady and unsteady flow conditions were performed. The test conditions were highly controlled and uncertainty was accurately predicted. The results obtained in this research consist of readily accessible, easy to emulate, detailed velocity fields and geometry. These results have been successfully used to validate our numerical model. This data can be used as a benchmark for further development of numerical CFD modelling through comparison of the main characteristics of the flow pattern.
