We describe the case of a patient with hypertrophic cardiomyopathy who experienced the failure of a transvenous implantable cardioverter defibrillator (T-ICD) lead and the following inability of a second T-ICD to convert a ventricular fibrillation. A subcutaneous ICD (S-ICD) was finally implanted and was effective at defibrillation test.
