Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic heart valve. In some embodiments, an apparatus includes an outer sheath, a tube member movably disposed within the outer sheath, a retention device coupled to the tube member, and a valve holder. A prosthetic heart valve is disposed within the outer sheath and includes an outer frame and an inner frame that is removably coupled to the valve holder. The outer frame is disposed in an inverted configuration relative to the inner frame. A first actuation wire is releasably coupled to a first portion of the outer frame and releasably coupled to the retention device at a first location on the retention device. A second actuation wire is releasably coupled to a second portion of the outer frame and releasably coupled to the retention device at a second location on the retention device.
