Minimally Invasive Approaches to Mitral Valve Surgery: Where Are We Now? A Narrative Review

Abstract

Minimally invasive mitral valve surgery (MiMVS) has been increasing in prevalence. This review focuses on the approaches, clinical outcomes, and patient selection for MiMVS. There are 4 minimally invasive approaches to the mitral valve: right mini-thoracotomy (including video-assisted and fully endoscopic), robotic mitral surgery, and transapical beating heart off-pump neochordal repair. Advantages over conventional surgery include less blood loss and transfusion, improved postoperative mobility, shorter length of stay, less postoperative atrial fibrillation, fewer surgical site infections, and improved cosmesis. This range of minimally invasive techniques will continue to evolve, providing options that are tailored for different patient populations.
