Echocardiographic Imaging of the Mitral Valve for Transcatheter Edge-to-Edge Repair.

Echocardiography continues to be the most effective imaging tool for the diagnosis and follow-up of mitral valve disease. This review addresses the use of transthoracic echocardiography and transesophageal echocardiography in the planning and guidance of transcatheter mitral valve therapies. Many of the echo-imaging guidance techniques are applicable to transcatheter intervention as a whole. However, given that the MitraClip is the only device approved for mitral regurgitation at present, specific attention is paid to this procedure, with additional focus on the guidance of noncentral repair. The imaging techniques discussed will be applicable to future devices.
