Aortic and Mitral Valve Replacement in Children: Retrospective Comparison of Tissue versus Bjork-Shiley Valves

Between 1970 and September 1984, only tissue (T, n = 83) or Bjork-Shiley (B-S, n = 59) prosthetic valves have been used for left-sided valve replacement at The Hospital for Sick Children, Toronto. A total of 108 infants and children underwent aortic (AVR, n = 59) and/or left atrio-ventricular (MVR, n = 49) valve replacement.
