“…CM&S has been adopted to investigate the fluid dynamic behavior of various cardiovascular devices, including ventricular assist devices [e.g., ( 13 , 14 )], prosthetic heart valves [e.g., ( 15 , 16 )], vascular stents [e.g., ( 17 – 19 )], intravascular catheters [e.g., ( 20 , 21 )] and stent grafts [e.g., ( 22 , 23 )]. This study specifically centers on prosthetic aortic valves, implantable devices designed to replace a native diseased aortic valve ( Figure 1A ).…”

Over the last years computer modelling and simulation has emerged as an effective tool to support the total product life cycle of cardiovascular devices, particularly in the device preclinical evaluation and post-market assessment. Computational modelling is particularly relevant for heart valve prostheses, which require an extensive assessment of their hydrodynamic performance and of risks of hemolysis and thromboembolic complications associated with mechanically-induced blood damage. These biomechanical aspects are typically evaluated through a fluid-structure interaction (FSI) approach, which enables valve fluid dynamics evaluation accounting for leaflets movement. In this context, the present narrative review focuses on the computational modelling of bileaflet mechanical aortic valves through FSI approach, aiming to foster and guide the use of simulations in device total product life cycle. The state of the art of FSI simulation of heart valve prostheses is reviewed to highlight the variety of modelling strategies adopted in the literature. Furthermore, the integration of FSI simulations in the total product life cycle of bileaflet aortic valves is discussed, with particular emphasis on the role of simulations in complementing and potentially replacing the experimental tests suggested by international standards. Simulations credibility assessment is also discussed in the light of recently published guidelines, thus paving the way for a broader inclusion of in silico evidence in regulatory submissions. The present narrative review highlights that FSI simulations can be successfully framed within the total product life cycle of bileaflet mechanical aortic valves, emphasizing that credible in silico models evaluating the performance of implantable devices can (at least) partially replace preclinical in vitro experimentation and support post-market biomechanical evaluation, leading to a reduction in both time and cost required for device development.

“…Numerical simulations that virtually reproduce thoracic endovascular aortic repair (TEVAR) represent innovative computational adjuncts that may potentially aid the preprocedural planning phase in the future by predicting perioperative or short-term postoperative technical events and results. 1 Such tools could be further optimized regarding their credibility and reliability by providing evidence of their effectiveness and workflow, as illustrated in this study that applied a recently developed TEVAR simulation methodology to a patient-specific case with preoperative distal thoracic aortic stent graft kinking. The patient provided informed consent for the publication of this case report and related imaging.…”
