Claim 9:
10. A system for antegrade delivery of a replacement valve, the system comprising:
an outer catheter configured as a pacing sheath;
an inner catheter comprising: a distal end region that is tapered, an engagement surface proximal to a distal end of the inner catheter, wherein the engagement surface is configured to sealingly couple to a distal end region of the outer catheter so that an outer surface of the inner catheter is flush with an outer surface of the outer catheter without a gap;
wherein the outer catheter is configured to receive the inner catheter, the outer catheter 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 arranged along a distal end region of the elongate body, wherein the plurality of electrodes is spaced from the distal end region by a standoff distance;
a plurality of electrical connectors extending proximally from the elongate body; and
a plurality of conductor cables forming a bundle extending helically around the elongate body 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 outer catheter, 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.
