title: [The emerging role of three-dimensional transesophageal echocardiography in guiding the MitraClip procedure].
abstract: Percutaneous edge-to-edge mitral valve repair with the MitraClip device has been shown to be a safe and effective procedure in selected patients with moderate-to-severe mitral regurgitation. Two-dimensional transesophageal echocardiography (2D TEE) is the primary imaging modality for guidance of the procedure. Real-time three-dimensional (3D) TEE has recently been used as additional imaging modality during the MitraClip procedure. In comparison with 2D TEE, 3D TEE provides additional information in several steps of the procedure, including precise positioning of the clip delivery system into the left atrium, correct alignment of the clip arms perpendicular to the coaptation line and confirmation of the correct grasping location. This review describes the relevant role of 3D TEE imaging during the procedure, but also its limitations.
