Arterial plaque dome model exhibits wall vibrations

Data was obtained from latex tube models, which replicated both healthy and diseased vessels with a plaque dome. The fluid mechanics model was used to develop code comprised of hemodynamic equations. The mechanics of the vessels were analyzed via their pressure — area relationship. The pressure area relation was determined for both a normal and plaque dome model. This relationship was applied to the hemodynamic model to compute pressure and flow. The model results showed large and low frequency wall vibrations occur. This was consistent with observations of sound generation in diseased blood vessels such as the carotid artery.
