Clinical Trial Summary

The EPYGON VALVE is an innovative mitral valve, intended for valve replacement of a native mitral valve through a minimally invasive implant procedure by means of a dedicated implant device.

The EPYGON VALVE is a bio prosthesis, composed by a functional assembly of bovine pericardium on a NiTinol stent.

The purpose of this trial is to assess the safety and feasibility of the Epygon™ Transcatheter mitral valve and the transapical delivery system, in adult patients with severe, symptomatic mitral regurgitation.

24. Patients with ventricular morphology (position of papillary muscles, ventricular wall hypertrophy) unsuitable with the study valve design;

25. Patients with aorto-mitral angle <120°;

26. Patients with a systolic/diastolic mitral valve area assessed as not compatible with the sizing policy matrix defined by the Sponsor.
