Abstract
A temporary holder for a physiologic mitral valve includes a structure which releasably clamps the annulus of the valve between the rim of a plate and a snap ring. The structure also includes a pair of papillary head holders which hold the papillary heads of the valve at a predetermined distance and angle from the annulus plate for optimum surgical positioning. The papillary heads are temporarily sutured to their holders and can be released by a simple scalpel stroke.
