The upper T mini-sternotomy approach allows for successful aortic valve surgery with excellent visualization and no complications. This minimally invasive technique reduces postoperative pain and speeds patient recovery.

Area of Science:

  • Cardiac Surgery
  • Minimally Invasive Procedures
  • Thoracic Surgery

Background:

  • Minimally invasive cardiac surgery aims to reduce patient morbidity and improve recovery.
  • The upper T mini-sternotomy is an evolving approach for cardiac procedures.

Purpose of the Study:

  • To review the efficacy of the upper T mini-sternotomy approach for aortic valve surgery.
  • To assess patient outcomes and surgical feasibility using this minimally invasive technique.

Main Methods:

  • Nine consecutive patients underwent isolated aortic valve replacement using the upper T mini-sternotomy.
  • Procedures included aortic valve stenosis, incompetence, and mixed disease.

Main Results:

  • Excellent aortic valve visualization was achieved in all cases.

  • Aortic valve replacement with mechanical prostheses was performed without intraoperative difficulties.
  • Mean aortic cross-clamp time was 83 minutes; mean cardiopulmonary bypass time was 97 minutes.
  • All patients were extubated in the OR, discharged on postoperative day 3, with no early or late complications.

    • Conclusions:

    • Aortic valve surgery is feasible via upper T mini-sternotomy using standard instruments and techniques.
    • This approach offers reduced postoperative pain and expedited patient recovery.
    • The method does not alter cardiopulmonary bypass or myocardial protection protocols.
