Mitral valve chordal repair has been a cornerstone technique for surgical correction of degenerative mitral regurgitation (MR). There is interest in duplicating the surgical option with less invasive, catheter-based alternatives. A transcatheter transseptal approach to mitral valve repair could present an opportunity for safer and perhaps earlier treatment for patients with MR. This summary in JACC: Cardiovascular Interventions demonstrates first-in-human proof-of-concept for transcatheter, transfemoral, transseptal mitral valve chordal repair. Although the patient ultimately required surgery, this is an important proof-of-concept that transseptal chordal replacement is feasible and that with continued refinement, it should become more durable and enable future permanent implants, adding to the toolbox of treatment for MR patients.
