Recommendations for Multimodality Cardiovascular Imaging of Patients with Hypertrophic Cardiomyopathy: An Update from the American Society of Echocardiography, in Collaboration with the American Society of Nuclear Cardiology, the Society for Cardiovascular Magnetic Resonance, and the Society of Cardiovascular Computed Tomography

Multimodality imaging plays a crucial role in the initial evaluation of patients with known or suspected HCM. In conjunction with clinical findings, imaging can confirm or refute the diagnosis. Imaging should be performed at clinical sites/centers of excellence with experience in the diagnosis and management of HCM. Imaging is central to risk stratification for sudden cardiac death as well as the evaluation of patients with chest pain and possible CAD. Along with ECG, imaging with echocardiography and/or CMR is needed for screening. In addition, imaging can guide treatment for obstructive HCM, be it with negative inotropic drugs, septal reduction therapy, or TEER of the mitral valve. The imaging staff should have a clear understanding of the strengths and limitations of the different imaging modalities and the clinical implications of the findings ascertained by imaging. Importantly, the results should be communicated clearly with the clinical team taking care of the patient.
