Abstracts: A 68 year-old male, with no past medical history, presented progressive shortness of breath on exertion and leg edema during the previous year. Trans-thoracic echocardiography depicted; severe left ventricular hypertrophy with mild systolic dysfunction (LVEF 50% biplane Simpson’s method), severe diastolic dysfunction and moderate left atrial enlargement. Left ventricular myocardial deformation imaging by two-dimensional speckle-tracking was paramount for elucidating the differential diagnosis.
