Abstract:Background Mitral valved stents tend to migrate or to develop paravalvular leakage due to high–left ventricular pressure in this cavity. Thus, this study describes a newly developed mitral valved stent anchoring technology.
Methods Based on an existing mitral valved stent, four anchoring units with curved surgical needles were designed and fabricated using three-dimensional (3D) software and print technology. Mitral nitinol stents assembled with four anchoring units were successively fixed on 10 porc… Show more
