The present teachings generally relate to translation catheter systems and method of using thereof in treating defective mitral valves. Specifically, a translation catheter system includes a catheter configured to move substantially laterally along the mitral annulus and the lateral movement of the catheter is substantially continuous and substantially adjustable. Accordingly, a method of using such a translation catheter includes advancing a first wire across the mitral annulus at a first treatment location, delivering a catheter at or near the first treatment location, moving the catheter substantially laterally to a second treatment location, and advancing a second wire across the mitral annulus, where the distance between the first and second treatment locations is substantially adjustable and optionally visualized.
