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.
