The structural alteration of the heart, entails a functional damage; depending on how severe is the lesion can be necessary the replacement of the structure with an implant that can be of a biological type. The opened possibilities to biological tissue processing for cardiovascular use, allow to have at the present time a variety of bioimplants for the surgical treatment of patients with diverse pathologies. In this sense it has been developed techniques for processing, conservation and storage of tissues, called homografts, which are obtained from cadaveric donors, in which still cellular viability is conserved. Unfortunately, of another hand, it is left the sadness to see frustrated the life of thousands of people who by violence or other accidental causes are death; although it increases the opportunities of relievement for great amount of patients who wait by biological implants derived of a donor; it is the ambivalence that exist between the opportunities to save lives and the social cost that represent the victims of the violence which they are offered like donors. Key words: Bioimplants, homografts, cadaveric donors.
