    Abstract: An implantable prosthetic valve includes a radially collapsible and expandable annular frame having three commissure attachment posts and four rows of circumferential struts. The rows include a first row, a second row downstream of the first row, a third row downstream of the second row, and a fourth row downstream of the third row and defining an outflow end of the frame. Each row of circumferential struts includes angled struts arranged in a zig-zag pattern. A leaflet structure includes three leaflets forming three commissures, each commissure being connected to one of the commissure attachment posts only at locations along the commissure attachment posts between a first plane that is perpendicular to a longitudinal axis of the frame and intersects crowns of the third row of struts and a second plane that is perpendicular to the longitudinal axis and intersects crowns of the fourth row of struts.

    Abstract: A valve catheter is advanced through a patient's vasculature while a prosthetic heart valve is attached to flexible extensions along a distal end thereof. The valve catheter is advanced through a tubular sleeve for exposing the prosthetic heart valve and allowing the prosthetic heart valve to self-expand while the extensions remain attached to the prosthetic heart valve. A release mechanism on a handle portion is actuated for releasing the prosthetic heart valve from the extensions, thereby implanting the prosthetic heart in a native heart valve. If the operator is not satisfied with the initial expansion, the prosthetic heart valve may be reoriented before release from the extensions by retracting the prosthetic heart valve back into the tubular sleeve, adjusting the orientation of the prosthetic heart valve and then re-advancing the valve catheter from the tubular sleeve for allowing the prosthetic heart valve to re-self-expand at a more desirable location.
