Abstract:
OBJECTIVETo compare the accuracy of live three-dimensional (Live-3D-TEE) and two-dimensional transesophageal echocardiography (2D-TEE) in the evaluation of functional anatomy of mitral regurgitation. METHDOS: Thirty-eight consecutive patients with severe mitral regurgitation were enrolled prospectively. The accuracy of Live-3D-TEE and 2D-TEE for functional assessment of mitral regurgitation was evaluated against surgical findings.
RESULTSThe accuracy in etiological assessment of mitral regurgitation was 94.7% with Live-3D-TEE and 89.5% with 2D-TEE (P=0.09). For assessment of lesions of the mitral valve, Live-3D-TEE showed an overall accuracy of 93.2%, significantly higher than that of 2D-TEE (88.6%, P=0.001). Live-3D-TEE also showed a significantly higher accuracy than 2D-TEE in localization of mitral valve lesions (93.3% vs 86.7%, P=0.000).
CONCLUSIONBoth Live-3D-TEE and 2D-TEE allow accurate assessment of the etiology of mitral regurgitation, but Live-3D-TEE can be more accurate in the evaluation of the lesions of the mitral valve and their localization.
