title: [The biological prostheses of Hancock in our experience of 250 subjects underwent a valvular replacement (author's transl)].
abstract: In this study we present the results of 5-years Follow-up of Clinical experimentation with biological prostheses of Hancock in 250 patients underwent a valvular replacement at the Cardiovascular Surgery Institute of Padua University in Verona. We report the immediate and long-term results with the death causes and the complications related above all with thrombo-embolic events. For such complications it was done a comparison relatively to the cases with mitral and aortic prostheses, with the results obtained from another Cardiovascular Surgery Center where are always applied artificial prostheses. From this comparison results that Hancock's biological prostheses has a major tendency to give incidence of embolic in the first months following the valvular replacement, but successively it is clearly to be prefered to artificial prostheses.
