[Complete atrioventricular block disclosing Fabry's disease]

Fabry's disease is a hereditary sex-linked sphinglopidosis characterised by abnormal cellular lipid overload in most organs due to deficiencies in enzymes implicated in the catabolism of certain neutral glycolipids. There are two main clinical forms; cardiovascular manifestations usually congestive cardiac failure, and renal manifestations progressing to renal failure and death due to uraemic coma. The authors report a case presenting with juvenile, symptomatic complete infrahisian atrioventricular block. They describe the different cardiovascular complications of Fabry's disease from a review of the medical literature.
