摘要
A system and method used to deliver an aortic valve therapeutic device to an aortic valve site includes a cable percutaneously introduced a cable into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The therapeutic device is passed over an end of the cable at the venous side and is secured to the cable. The therapeutic device is pushed in a distal direction while the second end of the cable is pulled in the proximal direction to advance the therapeutic device to the mitral valve site. A left ventricle redirector aids in orienting the therapeutic device and preventing migration of the cable towards delicate mitral valve structures and chordae tendoneae during advancement of the therapeutic device.
