Abstract
A disposable heart valve holder is correctly prepositioned on a prosthetic heart valve and is provided with a pair of resilient fingers in snapping engagement with the interior surface of an annular prosthesis. Each finger of the holder is provided with a detent for retention of the heart valve ring and with a grip for manual manipulation of the holder. The holder is rotatably removed or reattached to the heart valve in order to reduce trauma to the patient and decrease the time required for replacement surgery. One of the fingers of the holder is relatively more flexible than the other and is provided with a tapered leading edge in order to facilitate the removal or reattachment of the holder.
