Abstract
|
|
|
Between 1985 and 1993, 29 children from 1 to 15 years of age have undergone cardiac valve replacements at Buchon Sejong. Hospital. The patients were composed of 20 males and 9 females and 17 patients had congenital heart disease and 12 patients
had
acquired heart disease. Two of these patients have had second valve replacements due to paravalvular leakage and valve thrombosis. Single valve replacements were 29 and double valve replacements were 2. All the patients had received prosthetic
valves
except one. Among the 25 patients who had definite post-operative records, the overall mortality was 12%(4% was early mortality and 8% was late mortality).
25 patients were followed up with coumadin anticoagulation for total 633 patient-months(minimum 2 months to maximum 93 months, mean 25.3 months) and actuarial survival rate was 88.5*6.3% at 7 years and event free rate was 70.3*11.7% at 7 years.
These results suggest that pediatric valve replacements can now be performed at a low operative risk although various problems are still remained and the choice of valve is prosthetic valve mainly due to its durability at the present time.
