Abstract

OBJECTIVE

To 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.

RESULTS

The 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).

CONCLUSION

Both 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.

摘要

目的

比较实时三维经食管超声心动图（Live-3D-TEE）和二维经食管超声心动图（2D-TEE）在评估二尖瓣反流功能解剖方面的准确性。方法：前瞻性纳入38例连续的重度二尖瓣反流患者。以手术结果为对照，评估Live-3D-TEE和2D-TEE对二尖瓣反流功能评估的准确性。

结果

Live-3D-TEE对二尖瓣反流病因评估的准确性为94.7%，2D-TEE为89.5%（P=0.09）。对于二尖瓣病变的评估，Live-3D-TEE的总体准确性为93.2%，显著高于2D-TEE（88.6%，P=0.001）。Live-3D-TEE在二尖瓣病变定位方面的准确性也显著高于2D-TEE（93.3%对86.7%，P=0.000）。
