Valve-sparing aortic root replacement has the advantage of preserving the patient's own aortic valve. The complexity of the reported techniques to date restricts their use to a limited number of cardiac surgeons. This protocol describes step-by-step a standardized technique reproducible by a greater number of cardiac...

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Surgery

Background:

  • Acute type A aortic dissection (ATAAD) presents significant surgical challenges, particularly concerning the fragility of the aortic root.
  • Effective reinforcement of the aortic root is crucial for successful ATAAD repair and long-term patient outcomes.

Purpose of the Study:

  • To introduce and evaluate a new aortic root reinforcement technique for ATAAD surgery.
  • To report the early operative and midterm follow-up results of this novel technique.

Main Methods:

  • Retrospective analysis of 235 patients undergoing ATAAD surgery with the new technique (October 2011 - June 2016).
  • The technique involves placing inner and outer vascular graft rings reinforced with horizontal and vertical mattress sutures.
  • Postoperative imaging included CT angiography at discharge and annually during follow-up.

Main Results:

  • The 30-day mortality rate was 5.1% (12/235).
  • Intraoperative bleeding from the aortic root was minimal, with re-exploration rates at 0.79% (2/235).
  • Midterm survival was 90.2% over 4.2 ± 2.1 years, with no aortic root reoperations or complications like disruptions or re-dissections.

Conclusions:

  • The novel aortic root reinforcement technique is safe and effective for ATAAD surgery.
  • This method successfully reinforces fragile aortic root tissues, minimizing critical complications.
  • The technique demonstrates promising midterm results, enhancing patient survival and reducing reintervention rates.
