Nowadays, humans are suffering from chronic cardiovascular diseases, including Congenital Heart Defect (CHD). These diseases have far-reaching consequences, such as disruption of the daily life of humans by reducing their ability to perform daily routines. This problem is due to impaired cardiac pumping capability. The present numerical simulation studied the effects of CHDs on pressure drop and AWSS. Numerical calculation of non-Newtonian blood flow parameters, including power-law indices and the Reynolds number, were also investigated. To construct a 3D model of CHDs, an OSS program using DICOM and MRI was used. Besides, the vessel wall was assumed as solid. The non-Newtonian blood flow was assumed as a laminar flow with the slip boundary conditions at the vessel wall. AWSS, pressure drop, and dimensionless heat transfer coefficient are directly correlated with power-law indices, Reynolds number, and constant heat flux boundary conditions of the body. CHDs increased velocity, pressure drop, and AWSS in all steps of the simulation process.
