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.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
