1. A system for antegrade delivery of a replacement valve, the system comprising:
an outer catheter configured as a sheath for a catheter, the outer catheter comprising:
an elongate body having a lumen configured to receive the catheter, and
an engagement region within the lumen at a distal end region of the outer catheter; and
an inner catheter comprising:
a tapered distal end region,
an engagement surface proximal to the tapered distal end of the inner catheter, wherein the engagement surface is configured to detachably couple to the engagement 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,
a deflector on an outer surface of the inner catheter distal to the tapered distal end region, wherein the deflector is configured to radially expand to deflect away from chordae tendinae of the left ventricle,
a steering region between the engagement surface and a distal end of the inner catheter that is configured to bend, and
a guidewire lumen.
