摘要:
Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.
