Minimally invasive aortic valve surgery is safe and effective for routine use. This approach offers benefits like better heart function post-surgery and improved cosmetic results, with no negative effects found.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Procedures
  • Aortic Valve Operations

Background:

  • Minimally invasive aortic valve procedures were not routinely performed due to limited evidence and technical challenges.
  • Previous approaches were highly selective, not standard practice.

Purpose of the Study:

  • To evaluate the effectiveness and safety of routine minimally invasive aortic valve surgery.
  • To compare outcomes between minimally invasive and conventional sternotomy approaches.

Main Methods:

  • A single surgeon performed 46 minimally invasive aortic valve procedures using upper or transverse sternotomy.
  • Two other surgeons performed 40 aortic valve procedures via conventional sternotomy for comparison.
  • Data collected from September 1997 to February 1999.

Main Results:

  • Minimally invasive surgery showed a better postoperative ejection fraction (P=0.04) and lower pain scores (P=0.004).
  • Reduced transfusion rates (P=0.02) and shorter chest tube drainage were observed in the minimally invasive group.
  • No significant differences in operating time, pump time, or ICU stay; however, aortic clamp time was longer (P=0.001).

Conclusions:

  • Aortic valve surgeries can be routinely performed using the minimally invasive approach.
  • The minimally invasive technique demonstrates high effectiveness and safety.
  • This approach offers significant advantages without apparent negative effects.
