Implication

Catheter biopsy study finds uneven iron distribution in secondary haemochromatosis, indicating that endomyocardial biopsy is insensitive for detecting early cardiac iron overload.

Key Points

To evaluate catheter endomyocardial biopsy as a diagnostic technique for assessing myocardial iron deposition in secondary haemochromatosis.
Obtained catheter endomyocardial biopsies from four patients with clinical and biochemical evidence of severe haemochromatosis.
Measured transmural iron distribution across subendocardial and subepicardial layers and evaluated myocardial iron proteins using CM32 cation exchange resin chromatography.
Subendocardial myocardium contained only half the iron content found in the subepicardial layer, resulting in substantial sampling variation.
Among four patients, only one exhibited severe myocardial iron overload, while one patient in cardiac failure had endomyocardial iron within normal limits.
Iron-loaded myocardium showed a markedly increased haemosiderin:ferritin ratio of 5:1 compared to 2:1 in normal cardiac tissue.
