![]() 4-6 CMR may also inform choice of septal reduction therapy by defining unique aspects of LV anatomy that may be contributing to outflow obstruction. 2,4 With high spatial resolution and the unique opportunity to detect myocardial fibrosis, CMR provides detailed characterization of the HCM phenotype to aid in diagnosis, comprehensive phenotyping and reliable identification of high-risk morphologic features such as left ventricular (LV) apical aneurysm and extent of late gadolinium enhancement (LGE) (i.e., fibrosis) for sudden death risk assessment. 3 While echocardiography continues to be the foundation for evaluation of HCM patients, 3 the current guidelines emphasize the importance of a multimodality cardiovascular imaging strategy by integrating cardiovascular magnetic resonance (CMR) imaging into the assessment of nearly all HCM patients. 2 A number of these major guideline based treatment recommendations are discussed.įor over 50 years, cardiac imaging has played a central role in the diagnosis and management of HCM. 1,2 The recently updated 2020 ACC/AHA guideline for the diagnosis and treatment of HCM provides a comprehensive summary of these contemporary management strategies to provide an essential framework for which the practicing community can reliably implement these recommendations to achieve excellent outcomes for all HCM patients. The application of contemporary cardiovascular treatments and management strategies to hypertrophic cardiomyopathy (HCM) over the last decade have altered the natural history and course of this genetic heart disease, now providing the vast majority of at-risk HCM patients the reasonable expectation for extended (if not normal) longevity and excellent quality of life.
