The INSPIRIS RESILIA Aortic Valve™ is a stented tri-leaflet valve comprised of bovine pericardial tissue. The tissue is created by treating bovine pericardial tissue with Edwards Integrity Preservation. It incorporates a stable capping anticalcification process, which blocks residual aldehyde groups known to bind with calcium. Tissue preservation with glycerol allows the valve to be stored without a traditional liquid-based solution, such as glutaraldehyde. Therefore, valve is stored under dry packaging conditions and consequently does not require rinsing prior to implantation. The novel tissue preservation technology significantly improves hemodynamic and anticalcification properties compared with the standard Perimount valve in an ovine model. In this registry, data is collected over a period of 5 years to demonstrate these properties in a clinical real-life setting. Clinical outcomes, hemodynamic as well as safety parameters and quality of life data are documented into e-CRF at baseline, surgery, pre-discharge, 3-6 months and annually up to year 5. The required sample size was calculated using the online calculator at http://www.surveysystem.com/sscalc.htm. It was estimated, from COMMENCE Trial dataset that freedom from time-related valve safety events at 1 year (composite endpoint according to VARC-2) is around 0.915. The following table illustrates 95% CIs at different levels of risk: Sample Size Observed freedom from event 95%CI 400 0.900 ± 0.0294 400 0.910 ± 0.0280 400 0.915 ± 0.0214 400 0.920 ± 0.0266 400 0.930 ± 0.0250 20% of registry sites will be monitored with 100% source data verification
