Video Summary

The talk reviews sudden cardiac death risk in hypertrophic cardiomyopathy, noting an overall annual risk of about 1%. Current 2024 AHA/ACC guidelines recommend ICDs for secondary prevention after prior cardiac arrest, and consider primary-prevention ICDs for major risk factors: family history of sudden death, massive wall thickness, unexplained syncope, apical aneurysm, or ejection fraction under 50%. Cardiac MRI and ambulatory monitoring can refine risk, especially extensive late gadolinium enhancement and high-risk non-sustained VT. Risk should be reassessed every 1–2 years, using shared decision-making.
