Reoperative mitral valve surgery is increasingly common. A novel right anterolateral thoracotomy technique offers a less invasive, safer alternative to repeat sternotomy for valve reoperation.

Area of Science:

  • Cardiac Surgery
  • Thoracic Surgery
  • Cardiovascular Research

Background:

  • Reoperation on the mitral valve is rising due to bioprosthetic valve degeneration, endocarditis, and mechanical valve issues.
  • Repeated sternotomy for mitral valve reoperation presents significant technical challenges and risks.
  • Existing approaches for mitral valve reoperation can be complex and time-consuming.

Purpose of the Study:

  • To present a less invasive surgical technique for mitral valve reoperation.
  • To evaluate the feasibility and safety of right anterolateral thoracotomy for reoperative mitral valve surgery.
  • To offer an alternative to repeat sternotomy in patients requiring mitral valve reoperation.

Main Methods:

  • A cohort of 11 patients underwent mitral valve reoperation.

  • The surgical approach utilized was right anterolateral thoracotomy.
  • Key procedural elements included avoidance of aortic and right atrial cannulation, aortic cross-clamping, and cardioplegia.

    • Main Results:

    • The right anterolateral thoracotomy approach was successfully applied in 11 patients.
    • This technique proved to be less tedious, time-consuming, and dangerous compared to repeat sternotomy.
    • Favorable outcomes were observed in the patient cohort undergoing this minimally invasive reoperation.

    Conclusions:

    • Right anterolateral thoracotomy is a viable and advantageous approach for mitral valve reoperation.
    • This technique simplifies a complex procedure, reducing patient risk and operative time.
    • The presented method offers a promising alternative for managing degenerated or malfunctioning mitral valves in reoperative settings.
