Evolving anatomic, functional, and molecular imaging in the early detection and prognosis of hypertrophic cardiomyopathy.
Evolving imaging modalities in hypertrophic cardiomyopathy (HCM), such as tissue Doppler, speckle tracking, measures of myocardial blood flow, and cardiac magnetic resonance with gadolinium enhancement, have advanced our understanding of the pathogenesis of myocardial dysfunction in hypertrophic cardiomyopathy. These modalities have the potential to differentiate HCM from other causes of left ventricular hypertrophy when there is uncertainty about the diagnosis and to identify affected individuals in the pre-clinical phase of the disease process. Furthermore, preliminary data suggests that functional imaging techniques may add incremental value to conventional risk stratification tools to identify individuals at high risk for sudden death or progression to congestive heart failure.
