Abstract: A prosthetic heart valve has a plurality of valve leaflets that control directional flow of blood through a heart and a stent structure having a plurality of commissure posts supporting the valve leaflets. The stent structure has a covering over the plurality of commissure posts and has a sewing ring at an inflow end of the stent structure. Each of the plurality of commissure posts has a tip and a suture loop is attached to the covering at a location adjacent to or on the tip of the commissure post. Each suture loop provides a passage for a suture to pass through between the covering and the suture loop.

Abstract: Expandable docking stations for docking an expandable valve can include a valve seat, one or more sealing portions, and/or one or more retaining portions. The valve seat can include radiopaque markers affixed to a frame or an impermeable member. The radiopaque markers can indicate a deployment location of the valve. The docking stations can be deployed from a catheter including one or more radiopaque markers. Relative positioning of two or more radiopaque markers can provide an indication of the amount of deployment of the docking station.
