A device for engaging a heart valve prosthesis during implantation includes a handle and a low profile holder. The handle has a proximal end and a distal end. The distal end is attached to the low profile holder which includes a distal engaging surface adapted for engaging the heart valve prosthesis. The distal engaging surface of the low profile holder maintains a leaflet of the heart valve in a closed position during implantation. This provides a low profile to the heart valve and holder which facilitates insertion through a trocar in a patient.
