In recent years, transcatheter mitral valve replacement is a focused issue in the field of valve intervention, which brings hope to mitral regurgitation patients who are not suitable for surgical thoracotomy. This paper presents the case of echocardiography-guided transseptal mitral valve replacement with the HighLife system in an elderly female patient with severe mitral regurgitation who failed to respond to standard medical therapy. During the procedure, echocardiography was used to guide the wire looping, cinching, atrial septal puncture, ring closure, atrial septal balloon dilatation, prosthetic valve implantation and immediate postoperative evaluation. Echocardiography plays an important role in transseptal mitral valve replacement, which can help the procedural process and improve the safety of the procedure.
