Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Surgery

Background:

  • Ascending aorta dilatation with sinotubular junction disruption can lead to aortic regurgitation.
  • Current surgical options may be complex or time-consuming.

Purpose of the Study:

  • To describe an alternative, simplified surgical technique for ascending aorta replacement.
  • To address sinotubular junction (STJ) stabilization in aortic dilatation and regurgitation.

Main Methods:

  • A novel technique involving suspension of aortic commissures.
  • Invagination of a polyester fiber graft into the ventricles.
  • A two-suture line proximal anastomosis.

Main Results:

  • The described procedure is characterized by its ease and speed of execution.
  • The technique is hemostatic, minimizing blood loss.
  • Successful application in cases of ascending aorta dilatation with STJ loss.

Conclusions:

  • This alternative technique offers a simplified approach to ascending aorta replacement.
  • It effectively addresses sinotubular junction issues contributing to aortic regurgitation.
  • The procedure is suitable for specific patient populations with aortic dilatation.
