Zusammenfassung:An implant delivery system for delivering a replacement heart valve implant to a native valve annulus may include an elongate shaft assembly including an implant holding portion configured to constrain a replacement heart valve implant in a radially collapsed configuration. The elongate shaft assembly includes a primary visual indicator configured to be visible under fluoroscopy with an imaging device. The elongate shaft assembly includes a secondary visual indicator configured to be visible under fluoroscopy with the imaging device when the imaging device is aligned with a reference plane associated with the native valve annulus. The secondary visual indicator is not visible under fluoroscopy with the imaging device when the imaging device is misaligned with the reference plane associated with the native valve annulus.
