There are two forms of SRT: surgical myomectomy11,12 and alcohol septal ablation. Primary prevention with an ICD is reasonable for patients with severe hypertrophy (>30mm), family history of sudden death in a first degree relative, recent unexplained syncope, or "burnt-out" HCM (LVEF < 50%).2,6,7 The presence of non-sustained ventricular tachycardia on 24-hour Holter or abnormal blood pressure response to exercise, when added to other risk factors, also supports primary prevention ICD.14 Other risk factors that may influence the decision to place an ICD for primary prevention include marked late-gadolinium enhancement on magnetic resonance imaging (MRI) (>15%), the presence of an apical aneurysm, and some genetic mutations present in families with high prevalence of sudden cardiac death.3,6,7,15-17 Secondary prevention with ICD placement in those surviving SCD or with sustained ventricular tachycardia (VT) is universally recommended.6 In the case of syncope, a thorough evaluation for provoked obstruction is first required to avoid ICD implantation for syncope related to LVOTO rather than ventricular arrhythmias.7 Periodic reassessment of risk factors is recommended as part of ongoing follow up, with more frequent testing reserved for younger patients and those with borderline risk factors. People are born with the genetics for it, but the hypertrophy doesn't appear to start developing until adolescence, growth spurts, or beyond. An echocardiogram is commonly used to diagnose hypertrophic cardiomyopathy. With refinement of the techniques and greater experience, post-procedural outcomes following alcohol septal ablation are comparable to surgical myectomy in appropriately selected patients at expert centers.7 Selecting the right approach to SRT is challenging and should include not only the assessment of provider and center expertise, but also factors such as patient age, comorbid disease, and patient preference.2 Despite excellent intermediate and long-term results, some patients remain symptomatic or develop heart failure after SRT.13.

Screening and Risk Identification. Hypertrophic cardiomyopathy (HCM) is an inherited disease of the cardiac sarcomere that results in left ventricular hypertrophy, hyperdynamic function, microvascular dysfunction, impaired relaxation, and myocardial fibrosis.1 Clinical hallmarks include left ventricular outflow tract obstruction (LVOTO), arrhythmias, and heart failure.2,3 To date, no disease-modifying therapies have been identified, although clinical trials of novel therapeutics are in progress.4,5 This analysis focuses on HCM management strategies fundamental to the care of patients with HCM: LVOTO, sudden cardiac death (SCD), atrial fibrillation, exercise restriction, and heart failure.
