Apparatus for excising and removing a clip or suture joining leaflets of a native heart valve. The apparatus includes an elongate shaft configured for remote access to a native heart valve, the elongate shaft having a proximal end, a distal end, and a lumen defined therein, and a clamp at the distal end of the elongate shaft, the clamp configured to receive a clip or suture joining native leaflet tissue, the clamp including a passageway extending along a length thereof in communication with the lumen. The apparatus further includes a cutter moveable within the passageway to encompass a clip or suture joining native leaflet tissue received within the clamp and cut native leaflet tissue proximate the clip or suture.
