Evolution of Left Ventricular Hypertrophy in Patients with Hypertrophic Cardiomyopathy
Application of echocardiography to cardiac diagnosis in the 1970s represented a major advance in the non-invasive identification of patients with hypertrophic cardiomyopathy (HCM) [1, 2]. Subsequently, the utilization of two-dimensional echocardiography and other ultrasound modalities in large numbers of patients with HCM over many years have stimulated continued definition of the diverse morphologic expression of the disease, changes in left ventricular morphology which appear to be part of its natural history, and the clinical relevance of left ventricular hypertrophy within the broad spectrum of patients [3–18]. As a result, it has become apparent that the morphology of HCM may not be identical or even similar in different phases of life. With these considerations in mind, the present review is focused on the patterns of left ventricular hypertrophy and the relationship between age and left ventricular anatomy in patients with HCM.
