Fabry Disease: Percutaneous Transluminal Septal Myocardial Ablation Markedly Improved Symptomatic Left Ventricular Hypertrophy and Outflow Tract Obstruction in a Classically Affected Male

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.
