Modeling and application of aorta coarctation: support system for pre-operative decision

摘要

Decision Support System (DSS) improves health care through the support given to health professionals in the task of decision making. Numerous uses of DSS are done in the context of heart failure. In congenital heart disease, aorta coarctation (CoA) is one of the most common lesions, and represents a spectrum of aortic narrowing that can vary from a discrete narrowing to a severe one. To this end, a 3D-model of the aorta was created by the patient's CT-scan with the aim of improving the preoperative planning and a computation fluid dynamic (CFD) analysis was done to evaluate the results of the pre- and postsurgical hemodynamics. The main purpose of the following study is to provide an Application to support physicians during surgery. The application will enable to simulate an endovascular access and a stent-positioning procedure by varying both the position of the stent and the severity of the CoA, thus allowing to adapt the model to specific patient's conditions. This will help the physician choose the intervention to be made by providing a quick support to consult in terms of variation of hemodynamic parameters before and after the surgery with the patient.
