A 47-year-old woman was referred with increasing dyspnoea and neuropathic pain. During echocardiography, she showed the typical signs for a Fabry cardiomyopathy: global left ventricular function was normal with an ejection fraction of 65%. She had a concentric left ventricular hypertrophy with very prominent papillary muscles. In addition, the magnetic resonance tomography showed regional late enhancement in the postero-lateral wall which is the typical location of fibrosis in Fabry patients. She suffered from a genetically proven Fabry disease, and interestingly her family name is Mrs Fabry. Thus summarized, Mrs Fabry with a confirmed Fabry disease presented with a typically Fabry cardiomyopathy.

A 47-year-old woman was referred with increasing dyspnoea on exertion over 3 years. She had apparently been healthy without known heart disease. No murmurs had been described. She had observed occasional discomfort in her hands and feet that was triggered by very warm or cold temperatures. Sometimes, the pain was disabling and could last for several hours. On physical examination, the vital signs were normal. She had no corneal abnormalities, no cutaneous findings, and her neurological examination was normal. She had no overt evidence of cardiac enlargement, although an intermittent fourth heart sound and a mild systolic apical murmur were heard. Her laboratory tests were normal.
An echocardiogram revealed a normal ejection fraction of 65%. A concentric left ventricular hypertrophy (end-diastolic wall thickness of 14 mm) with very prominent papillary muscles were detected (Figure 1). The diastolic function was impaired and mild mitral insufficiency was seen. We were led to the diagnosis by her family history and were bemused when she announced her name was Fabry. Laboratory tests revealed a 50% reduction in alpha-galactosidase-A serum activity and the diagnosis of Fabry disease was confirmed by mutational analysis (deletion I354fsdel 15 bp). Cardiac magnetic resonance imaging demonstrated regional late enhancement in the postero-lateral wall typical for myocardial fibrosis in advanced Fabry cardiomyopathy.1 Renal function was normal without detectable proteinuria. There was no evidence for cerebrovascular involvement. We have followed over 120 patients with Fabry disease at our hospital over the last 6 years. We believe that the cardiac features of Fabry cardiomyopathy with prominent papillary muscles and fibrosis in the postero-lateral wall are unique.

Fabry disease is caused by a mutation in the gene encoding alpha-galactosidase-A that is needed to metabolize lipids. Since the gene is carried on the X chromosome, women are heterozygous and so have in the past been considered as carriers. However, some women harbouring the gene mutation may have symptoms of the disease. Symptoms usually begin during childhood or adolescence and include burning sensations in the hands and feet that gets worse with exercise and hot weather and small, raised reddish-purple papules on the skin. Lipid storage may lead to impaired arterial circulation and increased risk of heart attack or stroke. The heart may also become enlarged and the kidneys may become progressively involved. Eye manifestations, especially corneal deposits, may also be observed. Other symptoms include decreased sweating, fever, and gastrointestinal difficulties, particularly after eating. Johannes Fabry (1860–1930) from Germany and William Anderson from the UK, both dermatologists, independently described the disease in 1898. Our patient's name was obviously a coincidence and she was not related to the original describer. However, nomen est omen (which in Latin means the name is telling something about the future). Specific enzyme replacement therapy, which has proved to be efficient in male and female Fabry patients, was started to prevent further deterioration of disease.2
