In order to know a relation between therapeutic results of mechanical valve replacement and the age at the operation, patients with acquired valvular heart disease were comparatively studied on their pre- and postoperative states by age group-According to age at the time of operation, the patients were classified into 3 groups; Group A: under 40, group B: from 40 to 59, and group C: over 60 years old-When analysed preoperative states, Group A and C had nonrheumatic lesions in higher rate, but no difference in other various values was found among the 3 groups. The operative mortality rate, days for ICU stay, postoperative incidence of cardiac or other organ failure, and the actuarial postoperative survial rate were also similar in all 3 groupsl Postoperative improvements in NYHA class were observed in group C as well as in group A and B. Systemic thromboembolism was not prevalent in group A and C, whereas the incidence of thromboembolism was 0.77%/patient-year in group B. Cerebral bleeding resulting from the reversed effect of anticoagulant therapy especially occurred in patients of group C, thus the incidence of this complication was 2.97%/patient-year in this group. <BR>In conclusion, though the main causes of valvular heart disease were different in each age group, the results after mechanical valve replacement were similar and satisfactory. Cerebral bleeding was a fatal complication in the elderly patients, so strict management with anticoagulant therapy was necessary throughout the follow-up period.
