[The completion Bentall procedure: aortic root and ascending aorta replacement after prior aortic valve replacement]

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Surgery

Background:

• Ascending aorta and aortic root aneurysms require complex surgical management.
• Previous aortic valve replacement with a mechanical prosthesis can complicate reoperations.
• Prosthesis-sparing aortic root replacement is desirable in select cases.

Observation:

• A case of a patient with a normally functioning mechanical aortic prosthesis undergoing reoperation for aortic root aneurysm is presented.
• The
• completion Bentall
• technique, a modification of the Bentall procedure, was employed.
• This technique allows for aortic root replacement while preserving the existing prosthesis.

Findings:

• The
• completion Bentall
• technique simplifies reoperative aortic root surgery.
• It significantly reduces aortic cross-clamping and cardiopulmonary bypass times.
• The procedure demonstrated a good surgical result with reduced complication rates.

Implications:

• This modified technique offers a valuable alternative for prosthesis-sparing aortic root replacement in reoperations.
• It may improve outcomes and reduce morbidity in patients requiring repeat aortic surgery.
• Further studies are warranted to evaluate the long-term efficacy and safety of the
• completion Bentall
• technique.
