This research focuses on using analytical fluid mechanics to determine whether or not a mitral regurgitation (MR) patient's Echocardiogram reading can be trusted, to assess the severity of his Mitral Regurgitation (MR). MR occurs when the mitral valve inlet, separating the left atrium and the left ventricle does not fully close during ventricular systole, allowing regurgitant blood to flow backwards from the left ventricle into the left atrium. For clinicians, knowing the severity of this hack-flow is important in preventing eventual heart failure. The Coanda Effect phenomenon in a particular patient is believed to cause discrepancies in echocardiogram results, leading clinicians to sometimes incorrectly diagnose a patient's MR severity. We propose to generate a tool for reading undebatable solid geometries in an echocardiogram and using these to judge the prevalence of wall effect to distort a fluid jet being read. Using control volume analysis for a regurgitant jet in the mitral valve, an analytical solution for the expected flow profile, based on wall effects around the regurgitant jet is derived. Using a turbulent 3D ANSYS model, detailed velocity and momentum mappings of the blood flowing backwards from the mitral valve into the left atrium are obtained. We believe these are first steps towards understanding wall effects in MR and determining the level of trustworthiness of any echocardiogram reading of MR severity.
