Valve replacement in children under 14 years of age: a review of 22 years of experience.

From 1964 to 1986, a total of 18 valve replacement operations were performed in 15 children under 14 years of age, with 13% operative mortality. Eleven children had a mitral valve replacement, with 3 subsequently requiring reoperation. Twelve Starr-Edwards caged ball prostheses, 1 Björk-Shiley and 1 Carpentier-Edwards prosthesis were implanted in the mitral position, with 18% operative mortality. Three children underwent aortic valve replacement, 1 with a Björk-Shiley prosthesis and 2 with a Starr-Edwards. One patient had tricuspid valve replacement utilizing a Starr-Edwards valve. Thirteen patients had one or more cardiac operations prior to valve replacement. Two late deaths occurred 8 and 18 months, respectively, group, 1 from a cardiac arrhythmia and 1 from fulminating prosthetic valve endocarditis. There were no late deaths in other patients. There was one thromboembolic episode in the entire group. At follow-up, 10 patients were classified as New York Heart Association Functional Class I and 1 patient was Class III. Valve replacement in children can be carried out with low mortality and good long-term results using the Starr-Edwards caged ball prosthesis.
