• Fabry disease;
  • α-galactosidase A deficiency;
  • alcohol-induced percutaneous transluminal septal myocardial ablation;
  • left ventricular hypertrophy

Fabry disease (α-galactosidase A deficiency) is an X-linked recessive lysosomal storage disease in which left ventricular hypertrophy (LVH) is common, and if severe, may mimic hypertrophic obstructive cardiomyopathy. Alcohol-induced percutaneous transluminal septal myocardial ablation (PTSMA) has been used as a safe and effective method to alleviate LVH obstruction in patients with hypertrophic obstructive cardiomyopathy (HCM). We describe a case of a classically affected Fabry 53-year-old male with symptomatic HCM (NYHA class III with exertional angina) who was treated with PTSMA. The procedure safely and effectively alleviated symptomatic left ventricular outflow tract obstruction at long-term follow-up, and the patient's NYHA classification was reduced to NYHA class I to II.
