1. A system for antegrade delivery of a replacement valve, the system comprising:
an outer catheter configured as a sheath to receive an inner catheter, the sheath comprising:
an elongate body having a lumen configured to receive the inner catheter, wherein the elongate body is configured to extend from outside of a body to a left ventricular apex of the heart;
a hub at a proximal end of the elongate body, the hub comprising a hemostatic valve;
a plurality of electrodes at a distal end region of the elongate body;
a plurality of electrical connectors extending proximally from the elongate body; and
a plurality of conductor cables extending from the plurality of electrical connectors to the plurality of electrodes, so that each electrical connector electrically connects to a corresponding electrode of the plurality of electrodes; and
a pacing controller configured to electrically couple to the plurality of electrical connectors of the sheath, the pacing controller comprising one or more processors and a non-transitory computing device readable medium having instructions stored thereon that are executable by the one or more processors to cause the pacing controller to apply a heart pacing stimulation from the plurality of electrodes.
