Area of Science:

  • Cardiovascular Surgery
  • Infective Endocarditis
  • Prosthetic Valve Complications

Background:

  • Destructive prosthetic aortic valve endocarditis poses challenges for aortic root repair due to fragile annulus tissue.
  • Traditional suture techniques are often unsuitable for reconstructing the aortic annulus in these complex cases.

Observation:

  • A new surgical approach involves reconstructing the intervalvular area with a pericardial patch.
  • Aortic composite graft implantation is performed through the left atrium roof.
  • The resulting defect is then repaired with a second pericardial patch.

Findings:

  • The described technique successfully facilitated aortic root replacement in prosthetic valve endocarditis.
  • No surgical complications were observed during the 6-month follow-up period.

Implications:

  • This technique offers a viable alternative for aortic root reconstruction when the native annulus is compromised.
  • It potentially improves outcomes for patients with destructive infective endocarditis involving prosthetic aortic valves.
  • Further studies may validate this approach in larger patient cohorts.
