Mitral regurgitation is one of the most prevalent valvulopathies worldwide, and its surgical treatment is not feasible in all cases. The elderly and frail with several comorbidities and left ventricular dysfunction are often managed conservatively. Percutaneous treatment (repair or replacement) of the mitral valve has emerged as a potential option for those patients who are at a high risk for surgery. Mitral valve repair with the Mitraclip device proved both increased safety and mortality reduction in patients with severe mitral regurgitation. On the other hand, in the last decade, percutaneous mitral replacement opened new frontiers in the field of cardiac structural interventions. There are few mitral devices; some are in the early phase of development and some are waiting for CE mark of approval. The evolution of these devices was more complicated compared to the aortic technology due to the native mitral valve's complexity and access. This review aims to provide an overview of the current devices, their specific features, and their potential complications.

“…The Global Feasibility Study for Tendyne (Tendyne Holdings, LLC, Roseville, Minnesota-a subsidiary of Abbott Vascular) enrolled patients at eight study sites in the United States, Australia, and Norway between November 2014 and March 2016 (24,25). Inclusion criteria for the study were: age ≥18 years, MR grade 3 or 4 (primary or secondary), symptoms of dyspnea (NYHA Class ≥ II), and ability to provide informed consent (see Figure 2).…”

Surgical mitral valve intervention for severe functional, or secondary mitral regurgitation is a viable option for patients deemed to be operative candidates and can be performed via traditional sternotomy or by minimally invasive techniques with similar outcomes. Transcatheter mitral valve replacement is an emerging technology with a potential role in the treatment of functional mitral valve regurgitation. A plethora of devices are currently in development and in various stages of clinical investigation. Operative approach to transcatheter mitral valve replacement varies from a percutaneous transseptal approach to a hybrid percutaneous/surgical apical approach. The Tendyne, Intrepid and Evoque systems show promising results from their early feasibility studies in treatment of patients with mitral regurgitation that were too high risk for surgery. In this review, we describe considerations for surgical and transcatheter mitral valve replacement for functional mitral valve regurgitation.

“…Sorajja and colleagues describe using a new, anatomically designed mitral prosthesis (Tendyne prosthesis- Abbot Structural, Santa Clara, California) utilizing a transcatheter approach for MVR to treat patients with MR and severe MAC. 18 The valve is a self-expanding, fully retrievable and repositionable valve that is implanted via a transapical approach. A total of 9 patients with a mean age of 77 years old were recruited for this study at 5 different medical centers.…”
