Minimally invasive aortic valve replacement using "I" ministernotomy offers reduced recovery times and hospital stays compared to full sternotomy. This approach provides good exposure and cosmetic results for aortic valve lesions.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Techniques
  • Aortic Valve Disease Management

Background:

  • Minimally invasive surgical approaches are increasingly used for valvular heart disease.
  • This study reviews preliminary experience with minimally invasive aortic valve replacement.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of minimally invasive aortic valve replacement using an "I" ministernotomy approach.
  • To compare outcomes with traditional full median sternotomy.

Main Methods:

  • Eighteen patients underwent aortic valve replacement via "I" ministernotomy; 16 via full median sternotomy.
  • Cardiopulmonary bypass was established using aorto-right atrial cannulation.
  • Aortic cross-clamping and cardioplegia delivery were performed in both groups.

Main Results:

  • Aortic valve replacement was successful in all patients.
  • The "I" ministernotomy group had longer bypass and cross-clamp times but significantly shorter incisions, intubation duration, ICU stay, and hospital stay.
  • Patients in the ministernotomy group reported less pain and returned to normal activities faster.

Conclusions:

  • "I" ministernotomy provides excellent exposure, reduced pain, and faster recovery for aortic valve replacement.
  • This approach offers a good alternative for surgical correction of aortic valve lesions with improved cosmetic outcomes.
