LVH may be seen as a compensatory mechanism to increase cardiac output from the early stages of aortic regurgitation and is not necessarily associated with poor long-term prognosis. An LVEF <55%, a left ventricular end-systolic dimension >55 mm, and a left ventricular end-diastolic dimension <75 mm are signs of poor prognosis and usually require surgical evaluation.
