Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Surgery
  • Robotic Surgery

Background:

  • Mitral valve insufficiency necessitates effective repair techniques.
  • Minimally invasive approaches aim to reduce surgical trauma.
  • Computer-enhanced and telemanipulation systems offer new possibilities in surgery.

Purpose of the Study:

  • To develop a computer-enhanced, video-assisted approach for mitral valve repair.
  • To evaluate the feasibility of a telemanipulation system for mitral valve repair.
  • To assess the potential for a complete endoscopic mitral valve repair procedure.

Main Methods:

  • Performed computer-enhanced telemetric mitral valve repair on 10 patients with nonischemic mitral valve insufficiency.
  • Utilized the Intuitive surgical telemanipulation system with femorofemoral bypass and Port-Access cannulation.

  • Employed a small minithoracotomy, custom rib retractor, and endoscopic instruments for valve repair.

    • Main Results:

    • Successful mitral valve repair was achieved in 9 out of 10 patients using the telemanipulation system.
    • Ring implantation (partial or complete) was performed in 9 patients.
    • Median hospitalization was 8 days, with clinical improvement observed at 3-month follow-up in 7 patients.

    Conclusions:

    • Computer-enhanced mitral valve repair using telemanipulation is feasible with good functional outcomes.
    • The telemanipulation system shows promise for achieving true endoscopic mitral valve repair.
    • Prolonged surgical time and a learning curve are associated with this technique.
