Transesophageal echocardiography during MitraClip® procedure.
The percutaneous mitral valve (MV) repair procedure performed with the MitraClip delivery system is increasingly used to treat severe mitral regurgitation in high-risk patients. The treatment involves percutaneous insertion and positioning of a clip between the MV leaflets. Transesophageal echocardiography (TEE) plays a key role in the procedure by providing information regarding clip navigation, clip alignment to the MV coaptation line, transmitral advancement of the system, leaflet grasping, confirmation of valve tissue catching, and assessment of the final result. Real-time 3-dimensional TEE has increasing value in percutaneous MV repair providing high-quality visualization of both the heart and the intravascular devices. Optimal visualization by 3-dimensional TEE is obtained through both the atrial and ventricular aspects. In contrast to MV surgery, where TEE is involved in the prebypass assessment phase and in evaluation of the final repair, TEE is mandatory to guide management during MitraClip repair. Cardiac anesthesiologists may provide assistance to interventional cardiologists during the procedure itself in addition to their anesthetic-related tasks.
