1. A helical anchor for docking a mitral valve prosthesis, the helical anchor adapted to be received in and delivered from a coil guide catheter and comprising:
a plurality of coils having a preformed, coiled configuration after being delivered from the coil guide catheter and adapted to support the mitral valve prosthesis upon being fully delivered from the coil guide catheter and implanted with coil portions above and below a mitral valve annulus of a native mitral valve of a heart, wherein the plurality of coils comprises an upper coil, one or more middle coils, and a lower coil, wherein the upper coil has a larger diameter than the one or more middle coils and the lower coil, and wherein the upper coil is configured to engage a wall of an atrium of the heart at a position superior to and spaced axially from the mitral valve annulus after the plurality of coils have been fully delivered from the coil guide catheter.
