From March 1988 to October 1992, 201 CarboMedics cardiac valve prostheses (150 mitral, 50 aortic and l tricuspid) were implanted in 166 consecutive patients(mean age 38 years, male/female 66/100) by one surgical team operating on adult cardiac
parients
at Kyungpook University Hospital.
Total follow up represented 6646 patient-months(mean 40months)and follow up rate was 96%. One hundred and twenty-four patients(74.7%) were in NYHA functional class III or IV preoperatively and 164 patients(98.7%) were in class I or II
postoperatively.
Hospital mortality was 4.2% and late death was 4.2%. The actuarial survival at 78 months was 89.4%. The linearized incidence of valve related death, prosthetic valve thrombosis, anticoagulant related hemorrhage, non-structural dysfunction and
reoperation was 0.72%/pt-yr, 0.18%/pt-yr, 0.18%/pt-yr, 0.18%/pt-yr and 0.36%/pt-yr respectively. The 78 month rates of freedom from valve related death, prosthetic valve thrombosis, anticoagulant related hemorrhage, non-structural dysfunction and
reoperation were 94.9%, 99.4%, 99.4%, 98.6% and 97.9% respectivly. The 78 month rate of freedom from all valve related complications and deaths including hospital mortality was 90.9%.
These fact suggest that the CarboMedics cardiac valve has execellent result, low incidence of valve-related complications and no structural deterioration, and long term follow up study is necessary.
