A fluid-structure interaction model of the aortic valve in the presence of a subaortic stenosis

摘要

Hence, assessment of AS severity based on continuous-wave Doppler measurements may be altered in presence of concomitant SAS and may lead to erroneous diagnosis and clinical conduct in these patients. Although numerical simulations are currently developed taking into account the native valve with its elastic characteristics in a 3D model (De Hart 2003), this study is a first step to model an accurate medical problem that hasn't yet been described from a biomechanical point of view. In light of these preliminary results, it appears important to inform the clinicians about the potential pitfalls of Doppler-echocardiography for the assessment of AS severity in presence of SAS.
