Abstract
Method and devices for displacing leaflets of an existing valvular structure at an aortic valve position away from coronary ostia of an aorta are disclosed. An example method can include implanting a prosthetic heart valve within a native valve or previously implanted heart valve such that a commissure of the prosthetic heart valve is circumferentially aligned with a mid-portion of a leaflet of the native or previously implanted heart valve. The method further includes, during radially expanding the prosthetic heart valve into the native or previously implanted heart valve, applying pressure to the mid-portion of the leaflet with the commissure such that the leaflet is displaced away from the commissure and toward an inflow end of the prosthetic heart valve.
