Transesophageal Echocardiography Guidance during Transcatheter Mitral Valve Edge-to-Edge Repair for Severe Mitral Regurgitation Post-Mitral Annuloplasty: A Case Series

• Redo surgery for severe MR after MA can be high risk. • m-TEER can be successful if patient is not a candidate for redo surgery or valve-in-ring. • Small mitral orifice area and postdevice mean gradient may limit m-TEER to 1 device. • We present 3 cases of m-TEER for severe MR after MA. • TEE guidance may optimize m-TEER success for severe MR after MA.
