Optimized guidance of percutaneous edge-to edge repair of the mitral valve using real-time 3-D transesophageal echocardiography

Background  

Percutaneous edge-to-edge repair with the MitraClip device has been shown to allow effective treatment of mitral regurgitation. It is mainly guided by transesophageal echocardiography while fluoroscopic guidance is of less importance. The impact of real-time three-dimensional transesophageal echocardiography (RT 3-D TEE) for guidance of this complex interventional procedure has not been evaluated.
