Minimally invasive mitral valve surgery: from Port Access to fully robotic-assisted surgery

Currently, there is a growing interest in minimally invasive cardiac surgery, and despite early criticisms, it has become the preferred method of mitral valve repair and replacement in many institutions worldwide with excellent results. The interest in performing cardiac valve operations through minimal incisions was stimulated by Port Access technology and has evolved to include robotically assisted video-enhanced valve surgery. Robotic assistance has led to shorter operating times and represents an ideal tool to prepare for fully robotic-assisted cardiac procedures. This report will highlight minimally invasive mitral valve surgery with its evolution from Port Access techniques to fully robotic-assisted surgery. The nuances, strengths, and shortcomings, as well as the potential to enhance the valvular procedure, the promise to reduce hospital stay, earlier return to normal activity, less pain, better cosmesis, and the rethinking of surgical dogma that wide surgical exposure is essential for such complex intracardiac surgery are discussed.
