TI  - Clinical results with the Biocor porcine bioprosthesis.
PG  - 807-13
AB  - In order to evaluate our clinical results with the use of the Biocor prosthesis, 
      a total of 1,101 patients were studied. Follow-up was from 1 to 96 months (mean 
      48); cumulative follow-up in the aortic group (385 patients) was 1,230 patient 
      years and in the mitral group (716 patients) 3,018 patient years. Mitral patients 
      had 102 late complications (14.24%), and aortic patients had 51 (13.2%). A total 
      of 220 patients were under 20 years of age (176 mitral, 44 aortic). Intrinsic 
      valve failure in this subgroup was found in 43% of mitral patients and 29% of 
      aortic patients. Prosthetic endocarditis was more frequent in the aortic group 
      (45%) than in the mitral group (29.9%). Sixty-two patients were reoperated, with 
      a hospital mortality of 12.6%. Reoperation was more frequent in the mitral group 
      and in patients under 20 years of age. The actuarial curve free mortality related 
      to the bioprosthesis was 97.1% (32 patients). At the 8-year follow-up, 96.9% of 
      the aortic versus 95.2% of the mitral group were free of valve dysfunction, and 
      the majority were in Classes I or II of the New York Heart Association (NYHA) 
      classification. The incidence of reoperation, although significant, is 
      acceptable, especially since the bioprosthesis offers a safer alternative than 
      mechanical prostheses followed for similar periods. Analysis of our results 
      suggests the need for continued research for an ideal bioprosthesis.
