1. A method for positioning an intravascular device, the method comprising:
inserting, into a circumflex artery, a distal portion of a sensing device, the distal portion comprising a plurality of nodes;
determining a plurality of node locations of the plurality of nodes in a coordinate system when the distal portion of the sensing device is inserted into the circumflex artery;
determining a projected plane of a mitral annulus in the coordinate system based on the plurality of node locations; and
determining a projected deployment point for the intravascular device in the coordinate system based on the plurality of node locations.
