Apical aneurysm and myocardial bridging in a patient with hypertrophic cardiomyopathy: association or consequence of the myocardial bridging?

The identification of high-risk patients with hypertrophic cardiomyopathy (HC) for primary prevention of sudden cardiac death (SCD) remains a challenging issue, since major risk factors sometimes lack specificity. We report the case of a patient with HC and association of apical aneurysm and myocardial bridging who had been initially not implanted because she had only one major risk factor. She subsequently experienced a sustained ventricular tachycardia that finally motivated the implantation. We conclude that it is never an easy decision to implant a preventive implantable cardioverter-defibrillator (ICD). Nevertheless, additional criteria for a better selection of patients who would benefit from an ICD implant are certainly useful.
