ABSTRACT
Comprehensive understanding of mitral valve (MV) anatomy, function, and lesions is essential for the assessment of primary or organic mitral regurgitation (MR) and for the planning of MV repair. Although conventional two-dimensional transthoracic (2D TTE) or transesophageal echocardiography (2D TEE) continues to be the standard approach for the assessment of MR and prediction of MV repair, 2D echocardiography has several limitations with regard to the assessment of the complex MV anatomy. In contrast, real-time three-dimensional TTE (3D TTE) and TEE (3D TEE) provide comprehensive assessment of the MV morphology and function and allow better understanding of MV pathologies.1
