The Abbott Tendyne transcatheter mitral valve replacement (TMVR) system uses an anchor attached to the apex of the heart with a whether line attached to the valve. This helps to keep the valve anchored in the mitral annulus and prevent embolization. This anchor system was used because, unlike the aortic valve, the mitral valve has a very thin landing zone to secure the valve. The design also eliminated any hardware hanging or folding into the left ventricle, which could cause left ventricular outflow track (LVOT) obstruction, which can prevent blood flow through the aortic valve and to the rest of the body.
