St. Jude Medical prosthesis in children

Abstract

, 20 children 2 to 18 years of age underwent valve replacement with the St, Jude Medical prosthesis. Nine children underwent aortic valve replacement, eight underwent mitral valve replacement, and the three children with corrected transposition underwent left-sided tricuspid valve replacement. Of the 20 patients, 17 underwent 23 previous procedures. AU but five patients received adequate adult-sized prostheses. There was one hospital death (5 %). AU hospital survivors received maintenance doses of sodium warfarin. FoUow-up was 100% complete with a total of 106 patient-years. There were no late deaths and no thromboembolic or anticoagulant-related bleeding. None of the patients had prosthetic valve endocarditis or a periprosthetic leak. Reoperation was not required in any patient. The great majority of the children (16 of 19) were in New York Heart Association functional class I, two were in class Il, and one with complex congenital heart disease was in class In at the time this article was written. This study illustrates the excellent results of cardiac valve replacement with the St. Jude Medical prosthesis in children and confirms the safety of sodium warfarin in this age group.

Comparison of mechanical and biological prostheses when used to replace heart valves in children and adolescents with rheumatic fever

“…Overall mortality in our study was 8.2%, similar to that reported by other researchers 13 – 18 . All hospital deaths occurred in patients undergoing urgent surgery, being, therefore, in the fourth functional class, or requiring reoperation.…”

Long-term outcomes after mechanical aortic valve replacement with aortic root enlargement in adolescents

“…There were no redo procedures in our cohort due to PPM. Freedom from surgical re‐intervention rates with aortic root enlargement ranging between 85.1% and 91.0% at 10 years have been reported . It is almost inevitable that the adolescents will outgrow the prosthesis.…”

Early and late results of partial plication annuloplasty for congenital mitral insufficiency

“…For these reasons, mitral valve repairs were suboptimal in some cases. Recently, Ibrahim and colleagues 18 reported good early and long-term results of mitral valve replacement with prosthetic valves; however, many reports commented that prosthetic valve replacements are associated with significant morbidity and mortality and suboptimal long-term results. 8,19,20 Moreover, lasting anticoagulation therapy and reoperation after small- valve implantation were inevitable, and precise control of warfarin dosage is troublesome, especially in small children.…”
