The prosthesis (100) includes a pocket (106) formed from flexible material (104) disposed on a ring (102). When properly oriented in a mitral valve (120) of a heart (124) the pocket (106) expands as the mitral valve closes blocking any openings between the mitral valve leaflets (122). During systole backpressure from the blood in the left ventricle (128) presses against the mitral valve leaflets (122) as the papillary muscles move these leaflets (122) to a closed position. The mitral valve leaflets (124) coapt against the expanded pocket (106) minimizing or even eliminating gaps that would otherwise be present between the two leaflets (122).
