Summary
This summary is machine-generated.

Reoperative aortic root replacement (redo-ROOT) outcomes are excellent. Previous aortic root replacement (True-Redo) versus any prior operation (Any-Redo) showed similar in-hospital mortality but improved midterm survival for True-Redo.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Surgery

Background:

  • The clinical impact of prior aortic root replacement (True-Redo) versus any previous operation (Any-Redo) on outcomes after reoperative aortic root replacement (redo-ROOT) remains largely unknown.
  • This multi-institutional study addresses this gap by comparing outcomes in patients undergoing redo-ROOT.

Purpose of the Study:

  • To compare the clinical outcomes of reoperative aortic root replacement (redo-ROOT) in patients with a previous aortic root replacement (True-Redo) versus those with any prior operation (Any-Redo).
  • To identify risk factors for mortality in patients undergoing redo-ROOT.

Main Methods:

  • A multi-institutional retrospective review of 822 patients who underwent redo-ROOT between 2004 and 2021.
  • 174 matched pairs were created comparing True-Redo (n=184) and Any-Redo (n=638) groups based on preoperative demographics and concomitant operations.
  • Independent risk factor analysis was performed for early and late mortality.

Main Results:

  • True-Redo patients were younger (49.9 vs 55.3 years).
  • In-hospital mortality was similar (13% in both groups).
  • Midterm survival analysis at 4 years showed improved outcomes for the True-Redo group (P=0.046), despite longer bypass and crossclamp times. Older age, lower ejection fraction, and male sex were risk factors for in-hospital mortality.

Conclusions:

  • Clinical outcomes following redo-ROOT are excellent.
  • Performing a redo-ROOT after a previous aortic root replacement (True-Redo) does not worsen in-hospital morbidity or mortality and offers improved midterm survival compared to the Any-Redo group.
  • Individualized patient assessment is crucial for optimal outcomes in redo-ROOT procedures.
