ANATOMIC REGURGITANT ORIFICE AREA USING 3D-ECHOCARDIOGRAPHY IN DOGS WITH MYXOMATOUS MITRAL VALVE DISEASE (MMVD)

摘要

Aims of this study were to determine feasibility and repeatability of measuring anatomical regurgitant orifice area (AROA) using real-time 3D transthoracic echocardiography (RT3DE) in dogs affected by MMVD, and to determine if AROA obtained using RT3DE relates to the severity of MMVD assessed both with an echocardiographic scoring system (MRSS) and the American College of Veterinary Medicine (ACVIM) staging system.
