[The strategy for aortic root reconstruction; Bentall operation or native valve preserving operation?]

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Surgery

Background:

• The Bentall operation is the established standard for aortic root reconstruction in patients with aortic root aneurysms and aortic valve insufficiency.
• Native aortic valve-sparing procedures have gained recent popularity as an alternative surgical approach.
• Advancements in graft technology, such as the Valsalva graft, offer potential benefits in valve implantation and hemodynamic function.

Purpose of the Study:

• To evaluate the outcomes of aortic root reconstruction techniques at our institution.
• To compare the efficacy of the Bentall operation, David operation, and Valsalva graft procedures.
• To assess the suitability of different surgical methods based on patient condition and aortic pathology.

Main Methods:

• Retrospective analysis of patients undergoing aortic root reconstruction.
• Selection criteria: Bentall operation for severe damage or redo cases; David operation for simple annuloaortic ectasia and aortic valve insufficiency.
• Implementation of Valsalva grafts for enhanced prosthetic valve implantation and hemodynamic performance.

Main Results:

• The Bentall operation remains a reliable option for complex aortic root reconstructions.
• The David operation is effective for specific cases of annuloaortic ectasia with aortic valve insufficiency.
• The Valsalva graft facilitates larger prosthetic valve insertion and improved hemodynamics.

Conclusions:

• A tailored approach to aortic root reconstruction, selecting between Bentall, David, and Valsalva graft procedures, yields optimal patient outcomes.
• The choice of surgical technique should be individualized based on the severity of aortic disease and patient factors.
• Valsalva grafts represent a valuable advancement for aortic root surgery, offering improved prosthetic valve options and hemodynamic results.
