Brief Summary

The IMPACT Registry represents a non-interventional, prospective, open-label, multicenter, international registry with a follow-up of 5 years that includes data of patients undergoing aortic valve replacement with the Edwards INSPIRIS RESILIA Aortic Valve™. The IMPACT Registry will be performed in up to 25 participating sites across Germany, Austria and Switzerland. A minimum number of 500 patients (20 patients per center) will be enrolled. Patients will undergo follow-up visits at baseline, surgery, pre-discharge, year 1, year 3 and year 5.

Detailed Description

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 (Flameng et al., 2015). The RESILIA tissue has been studied in the COMMENCE trial: Two year data show that the NYHA class improved in 65.7% of patients, effective orifice area after implantation was 1.6 ± 0.5 cm2; mean gradient was 10.1 ± 4.3 mmHg; and paravalvular leak was none/trivial in 94.5% of patients (mild to moderate in 0.5%) (Puskas et al., 2017).

On the sizes 19 - 25 mm the INSPIRIS RESILIA Aortic Valve™ has been outfitted with the VFit technology, which incorporates two novel features designed for potential future valve-in-valve procedures: fluoroscopically visible size markers and an expandable cobalt chromium alloy band. No clinical data are available that evaluate the use of the INSPIRIS RESILIA Aortic Valve™ in patients to date.
