Robotically assisted mitral valve surgery using the port-access technique offers comparable outcomes to sternotomy but with reduced trauma. This minimally invasive approach leads to shorter hospital stays and improved patient recovery.

Area of Science:

  • Minimally Invasive Cardiac Surgery
  • Robotic Surgery
  • Cardiovascular Surgery

Background:

  • Sternotomy for mitral valve surgery can cause significant trauma.
  • Minimally invasive techniques aim to reduce surgical morbidity.
  • Robotically controlled, video-assisted approaches offer potential advantages.

Purpose of the Study:

  • To evaluate robotically controlled, video-assisted mitral valve surgery using the port-access technique.
  • To compare outcomes with traditional median sternotomy.
  • To assess the feasibility and benefits of minimally invasive mitral valve repair and replacement.

Main Methods:

  • 221 patients underwent robotically assisted mitral valve surgery via right minithoracotomy with port-access cardiopulmonary bypass.

Related Experiment Videos

  • An endoscope with a voice-controlled robotic arm (AESOP 3000) was used for visualization and instrument control.
  • Outcomes were compared to a historical cohort of 220 patients who underwent sternotomy.

    • Main Results:

    • Mean operating time was 3.5 hours, aortic cross-clamp time 58 minutes.
    • Mean intensive care unit and hospital stays were 22 hours and 6.4 days, respectively.
    • No re-exploration for bleeding, no late deaths or re-operations; significant improvement in NYHA functional class.

    Conclusions:

    • Video and robotic assistance in port-access mitral valve surgery minimize incision length and provide excellent visualization.
    • This approach yields comparable results to sternotomy with reduced ICU stay, blood transfusion, and earlier discharge.
    • Robotically assisted minimally invasive mitral valve surgery offers significant advantages over sternotomy.
