Insights
Cardiac magnetic resonance (CMR) improves sudden cardiac death (SCD) risk assessment in hypertrophic cardiomyopathy (HCM). This imaging technique identified high SCD risk in a patient initially assessed as low-intermediate, guiding crucial therapy decisions.
Area of Science:
- Cardiology
- Medical Imaging
- Genetics
Background:
- Hypertrophic cardiomyopathy (HCM) poses a risk of sudden cardiac death (SCD).
- Traditional risk stratification methods for SCD in HCM have limitations.
- Cardiac magnetic resonance (CMR) is a newer imaging modality for cardiovascular assessment.
Abstract:
Cardiac magnetic resonance (CMR) has been recently implemented in clinical practice to refine the daunting task of establishing the risk of sudden cardiac death (SCD) in patients with hypertrophic cardiomyopathy (HCM). We present an exemplificative case highlighting the practical clinical utility of this imaging modality in a 24-year-old man newly diagnosed with an apical HCM. CMR was essential in unmasking a high risk of SCD, which appeared low-intermediate after traditional risk assessment. A discussion examines the essential role of CMR in guiding the patient's therapy and underlines the added value of CMR, including novel and potential CMR parameters, compared to traditional imaging assessment for SCD risk stratification.
