PG  - 668-71
AB  - We evaluated long-term results of valve replacement with bioprosthesis in 59 
      patients. Freedom from primary tissue failure and reoperation declined more than 
      seven years after valve replacement. Seven patients underwent repeat operations 
      because of primary tissue failure in our hospital. Their ages ranged from 32 to 
      54 years, two cases were male and five were female. At repeat operation, 
      mechanical valve prosthesis were implanted to mitral position in all seven 
      patients, tricuspid annuloplasty was added in five patients, and aortic valve 
      replacement was added in one patients. The New York Heart Association (NYHA) 
      functional classifications were grade II for 1 patient, III for 1, and IV for 5 
      preoperatively. Five patients had severe pulmonary hypertension preoperatively, 
      and three of them were died after operation. The removed bioprostheses showed 
      tears, perforations or calcifications of cusps and commissural detachments.
