“…Currently, TAV implantation is considered as an established technique for the treatment of patients with severe symptomatic AS. In addition, there has been a recent trend toward a more extensive use of TAV devices in patients with an intermediate to high-risk profile [14]. Although significant experience has been gained and outcomes of TAV implantations are encouraging with a 3-year survival rate of 71.6% [15], various periprocedural complications such as acute kidney injury, vascular complications, pacemaker implantation, paravalvular regurgitation, and major bleeding have been reported [4, 12, 15-17].…”

In this study, we developed a computational framework to investigate the impact of leaflet geometry of a transcatheter aortic valve (TAV) on the leaflet stress distribution, aiming at optimizing TAV leaflet design to reduce its peak stress. Utilizing a generic TAV model developed previously [Li and Sun, Annals of Biomedical Engineering, 2010. 38(8): 2690-2701], we first parametrized the 2D leaflet geometry by mathematical equations, then by perturbing the parameters of the equations, we could automatically generate a new leaflet design, remesh the 2D leaflet model and generate a 3D leaflet model from the 2D design via a Python script. Approximately 500 different leaflet designs were investigated by simulating TAV closure under the nominal circular deployment and physiological loading conditions. From the simulation results, we identified a new leaflet design that could reduce the previously reported valve peak stress by about 5%. The parametric analysis also revealed that increasing the free edge width had the highest overall impact on decreasing the peak stress. A similar computational analysis was further performed for a TAV deployed in an abnormal, asymmetric elliptical configuration. We found that a minimal free edge height of 0.46 mm should be adopted to prevent central backflow leakage. This increase of the free edge height resulted in an increase of the leaflet peak stress. Furthermore, the parametric study revealed a complex response surface for the impact of the leaflet geometric parameters on the peak stress, underscoring the importance of performing a numerical optimization to obtain the optimal TAV leaflet design.

“…Although the rate seems higher than after conventional surgical AVR using other bioprostheses, the PMI rate after RDAVR has been decreasing over time (from 17.2% (2007-2008) to 5.4% (2016)) 5 and is not inferior to that with TAVR (14.7% vs. 9.8% in RDAVR). 13 Both of our patients had atherosclerotic disease in the peripheral artery and/or descending aorta. In case 1, axillary artery graft cannulation was selected, but was timeconsuming.…”

Background: Rapid deployment aortic valve replacement has been developed to shorten procedural times and to facilitate minimally invasive cardiovascular surgery. Methods and Results: As a representative rapid-deployment valve, the balloon-expanding INTUITY Elite (the 2nd-generation Edwards INTUITY Valve System) was uneventfully implanted via a right lateral mini-thoracotomy in 2 patients with severe aortic valve stenosis. Both of them recovered quickly and were discharged from hospital without significant adverse events. Conclusions: Implantation of the INTUITY Elite valve via right mini-thoracotomy is feasible and safe.
