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 comprise advancing a distal end portion of a delivery apparatus toward a native valve; visualizing under fluoroscopy and for a selected imaging view, a position of a radiopaque marker on the distal end portion relative to a guidewire extending through the delivery apparatus, the marker circumferentially offset from a selected commissure of the radially compressed prosthetic valve by a predetermined amount that is determined based on the selected imaging view; rotating the delivery apparatus until the marker is centered along the guidewire; and advancing the distal end portion into the native valve and inflating the balloon to radially expand and implant the prosthetic valve in the native valve such that the selected commissure is aligned with a commissure of the native valve.
