Abstract

Computational fluid dynamics (CFD) is a broadly used technique in mechanical, biomedical engineering or in medical studies to solve complex problems by analyzing blood flow, heat transfer, and associated diseases analyzation by using computer simulations. Hence, CFD has been increasingly used in medical research of coronary artery disease because of its high-performance computational methods. These simulation tools used to predict the behavior of cardio vascular blood flow in the human anatomy. The methodology used in this project is, firstly we performed the segmented and reconstruction of left coronary artery model from CT-scan data using Mimics (Materialize). Then the segmented models were then 3Dprintedusing a TPU-85 (Thermal Plastic Polyurethane-85) material used the Fused Deposition Modeling (FDM) printer. But, we also perform the numerical analysis of 3d printed coronary model using ANSYS version 2022(R2). The reconstructed geometry has been used to analyze the local blood flow fields and flow profiling due to changes of coronary artery geometry, therefore, recognizing risk factors of development and progression of coronary artery disease using CFD simulation techniques. However, use of 3-D printed models based on medical imaging modalities or reconstructed geometries of present project can exactly replicate complex anatomy of left coronary artery and pathologies of the associated for cardio vascular system. In this project another section provided the use of 3-Dprintingisatool to produce the patient actual left coronary artery that can be used for both education and surgical planning in these diseases. Hence concludes that, 3D printed patient-specific left coronary can be used in a non-invasive in vitro environment to quantify coronary artery ischemia with good correlation and concordance to that of invasive Fractional Flow Reservoir (FFR). However. the numerical analysis results of the present work gives the hemodynamic parameters such as pressure, velocity and Wall Shear Stress (WSS).
