This Guideline has been replaced in July 2022 with, "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." The purpose of this document is to review the strengths and applications of the current imaging modalities and provide recommendation guidelines for using these techniques to optimize the management of patients with HCM. The recommendations are based on observational studies, sometimes obtained in a small number of patients, and from the clinical experience of the writing group members, given the scarcity of multimodality imaging comparative effectiveness studies. Notwithstanding these recommendations, the writing group believes that the selection of a given imaging modality must be individualized.
