Endomyocardial biopsy after heart transplantation in children.
Clinical evaluation, physical examination, and noninvasive testing have been suggested as adjuncts to endomyocardial biopsy for diagnosing acute graft rejection in children after heart transplantation. Because the consequences of delayed diagnosis or unnecessary treatment of rejection may be serious in pediatric transplant recipients, we reviewed our experience with repeated endomyocardial biopsy in seven children (aged 6 months to 19 years) and assessed the sensitivity and specificity of clinical and noninvasive data for diagnosing acute rejection. There were no serious complications in 71 biopsy procedures. In no patient did the presence of abnormal clinical findings or noninvasive testing coincide with treatable rejection that was proved on biopsy. However, there were nine episodes of treatable rejection in the absence of abnormal physical findings or noninvasive studies. At this time we consider repeated endomyocardial biopsy to be a feasible and safe procedure in infants and children and do not consider clinical findings and noninvasive testing sufficient to make therapeutic judgments in regard to acute graft rejection.
