Value Of Endomyocardial Biopsy And Immunohistological Studies In Establishing The Prognosis Of Cardiac Amyloidosis

The authors report four cases of cardiac amyloidosis, the diagnosis of which was confirmed by endomyocardial biopsy.They underline the value of immuno-histological studies with labelling of the biopsy fragments with anti-transthyretin and anti-light chain immunoglobulin antibodies.This approach provides a more precise typing of amyloidosis and a more accurate evaluation of die prognosis.
