The use of sutureless valves in the case of a heavily calcified aortic homograft allows for relatively quick and safe replacement. Due to the nitinol frame, which is selfanchored in the aortic valve annulus and in the sinotubular junction (STJ), no complete annular decalcification or fixation with stitches is required. In conditions of significant calcification this may represent a technical problem.
