The Feasibility Study of Polymer Artificial Heart Valve for the Treatment the Mitral Valve Disease.

Summary

The study aims to evaluate the feasibility and safety of polymer artificial heart valve designed and developed by Shanghai HeartEpoch Medical technology Co. Ltd. for the treatment of the mitral valve diseases.
