Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Surgery

Context:

  • Annuloaortic ectasia (AAE) is a condition affecting the aortic root.
  • The David-V procedure is a valve-sparing aortic root reimplantation technique.
  • Current techniques may present challenges in surgical exposure and graft adjustment.

Purpose:

  • To present an original modification of the David-V procedure.
  • To simplify the surgical exposure during aortic root reimplantation.
  • To improve the adjustment of the native aortic root anatomy and the graft.

Summary:

  • A novel modification of the David-V procedure for annuloaortic ectasia is described.
  • This technique facilitates surgical exposure and enhances the adjustment of the aortic root and graft.
