ABSTRACT
Three cases of hypertrophic cardiomyopathy are described. The first case, a man aged 17 years, died suddenly, while the second case was diagnosed in a 40-year-old male who presented with auricular fibrillation; this patient died two years later from a cerebral tumour. The third patient, who died at the age of 72 years from cerebral haemorrhage, had had a pacemaker inserted five years previously because of atrioventricular block. The cardiomyopathy was diagnosed only at autopsy. The morphological features of the heart in these cases are documented. The characteristic histological aspect of the myocardial fibres, commonly referred to as disarray, is described and our findings are compared with those in the literature. The relationship between the various morphological presentations and their clinical manifestations is discussed.
