Abstract: Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. In some examples, a delivery apparatus can include a first shaft configured to rotate around a central longitudinal axis of the delivery apparatus to rotationally align a prosthetic valve mounted on the delivery apparatus with native anatomy, a second shaft extending through the first shaft and having a distal end portion extending distally beyond a distal end portion of the first shaft, an inflatable balloon coupled to the distal end portion of the first shaft, and a distal shoulder mounted on the distal end portion of the second shaft and arranged within a distal end portion of the balloon. The distal shoulder comprises a base portion and a flared portion that extends radially outward from the base portion, and a radiopaque marker is disposed on the flared portion.

Abstract: Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. In some examples, a method can include advancing a distal end portion of an assembly toward a native heart valve, the assembly comprising a delivery apparatus and a prosthetic heart valve, and including one or more radiopaque markers, where one radiopaque marker is suspended within a cell of a frame of the prosthetic heart valve and aligned with a commissure of the prosthetic heart valve. The method further includes receiving a fluoroscopic image in a selected imaging view of the prosthetic heart valve on the delivery apparatus, determining, based on the fluoroscopic image and the one or more radiopaque markers, whether the prosthetic heart valve is in a desired rotational orientation, and rotating the assembly until the prosthetic heart valve is in the desired rotational orientation.
