Reply to the Editor:
It is a fact that implantation of a homograft and that of a stentless heterograft in the mitral position are based on the same principles. However, unlike Vrandevic, Gontijo, and Fantini, we believe that the adjunction of pericardial patches and the use of pledget-supported sutures do not improve the safety of the papillary muscle fixation. Ultimately, the healing process is the best guarantee of firm papillary muscle attachment. Ideally, in the future the use of mitral homografts or stentless heterografts will provide new alternatives for valve replacement in selected cases.
