Cardiovascular diseases are the leading cause of death worldwide. Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease, but only 10-20% of cases are clinically identified. Arrhythmias and sudden cardiac death, in addition to congestive heart failure, are the main causes of death in HCM. Multimodal imaging is essential for diagnosis and risk stratification. Echocardiography is the first-line imaging technique due to its availability and versatility. Late gadolinium enhancement in cardiac magnetic resonance imaging identifies myocardial damage and fibrosis, constituting a risk marker. Gated-SPECT allows for the evaluation of myocardial perfusion and intraventricular dyssynchrony, representing a risk marker for ischemia due to microvascular dysfunction or coronary artery disease, as well as for the demonstration of myocardial fibrosis. The contribution of different imaging techniques to risk stratification in adult patients with HCM is presented.
