The present invention relates to a buttress for cardiac valve reconstruction of atrioventricular cardiac valves. The buttress (10) comprises an elongate member (12) formed from a fabric bendable, in use, into an open substantially ring-shaped configuration dimensioned to fit against the base of the cusps of the cardiac valve. The elongate member (12) is substantially cuboid-shaped and is formed from two superimposed layers (34, 36) of the fabric, in which the layers (34, 36) are fastened together by longitudinally extending seams (14, 16) having inwardly extending, opposing selvedges (24, 24', 28, 28').
