Real time three dimensional transesophageal echocardiography (3D TEE) is probably the most powerful and convincing imaging method for understanding the complicated multiform morphology and for evaluating geometry, dynamics and function of degenerative and functional mitral valve (MV) regurgitation. Moreover, color Doppler 3D TEE has been valuable to identify the location of the regurgitant orifice and the severity of the mitral regurgitation. 3D TEE has been shown to be of enormous value in helping surgeons to perform MV repair. In addition, due to its ability to show a "panoramic" view of the "theater" where the procedure takes place, it has become an indispensable companion of 2D TEE during percutaneous edge-to-edge repair. A novel hybrid imaging modality where echocardiography is merged with fluoroscopy, may in the future further improve guidance of this and other complex percutaneous transcatheter interventions.
