Official Title: Velocity Vector Imaging in Patients With Moderate-to-Severe Aortic Regurgitation
Brief Summary: Velocity Vector Imaging may provide reliable and detailed information on left ventricular segmental function in asymptomatic patients with moderate-to severe AR. This may help to identify subclinical myocardial dysfunction in order to operate early enough to prevent postoperative heart failure and restrict unnecessary early operation which could be associated with operative risks and mortality related to prosthetic valves.
