Correct answer: E — ICD implantation should be considered

The ESC HCM Risk-SCD calculator estimates 5-year risk. A score ≥6% is considered high risk and ICD implantation should be offered. For intermediate risk (4–6%), ICD should be considered. For <4%, ICD is generally not indicated. This patient's 7.2% risk warrants discussion regarding ICD implantation.
