title: [Endomyocardial biopsy in childhood].
abstract: The experience with endomyocardial biopsy in pediatric age is still limited. From February 1986 to August 1990, 144 right ventricle endomyocardial biopsies were performed in 84 patients (age range 33 days--14 years, median age 31 months, weight range 3--57 kgs). Clinical diagnosis was: dilated cardiomyopathy in 50 patients; graft reject in 19; hypertrophic cardiomyopathy in 4; restrictive cardiomyopathy in 5; heart tumor in 3; ventricular arrhythmia in 3. The bioptome was introduced directly, without the use of a long sheath. There were no major complications; 2 patients experienced complete transient atrioventricular block and in 1 case right ventricular perforation occurred. In 11/45 patients (27%) with the clinical diagnosis of dilated cardiomyopathy and available myocardial specimens, acute myocarditis was diagnosed. In 47/65 procedures in the transplanted patients, a moderate to severe rejection was diagnosed. In the remaining patients, endomyocardial biopsy did not help the clinical diagnosis. We conclude that the right ventricular endomyocardial biopsy is a safe procedure in pediatric age; its utility is mostly limited to the diagnosis of acute myocarditis and graft reject after cardiac transplantation.
