Why the study?
Does valve replacement with the Björk-Shiley prosthesis improve clinical outcomes and prevent complications in children with valve disease?
Does valve replacement with the Björk-Shiley prosthesis improve clinical outcomes and prevent complications in children with valve disease?
The Björk-Shiley tilting disc valve prosthesis demonstrated favorable clinical remission and no thromboembolic complications over 6 to 26 months in a small pediatric cohort.
Supports short-term remission after Björk-Shiley implantation in children; leaves open long-term safety in larger prospective studies.
Between 1971 and 1974, 26 valve replacements with the Björk-Shiley tilting disc valve prosthesis were performed in 23 children between 4 and 16 years of age. Mitral valve replacement was carried out in 11 patients, aortic valve replacement in 9 and double replacement in the other 3 patients. Several of the patients presented associated lesions which were also corrected at the same intervention, One patient died during the postoperative period; the remaining 22 all showed significant clinical remission. No incidents of thromboembolism or complications of any other nature were observed during follow-up periods of 6 to 26 months. It is our belief that the Björk-Shiley valve represents an improvement over other prostheses currently used for the surgical correction of valve disease in children.
