Reoperative aortic valve replacement after bio-Bentall using a double sewing ring technique.

Area of Science:

• Cardiovascular Surgery
• Cardiac Valve Repair
• Bioprosthetic Valve Performance

Background:

• Structural valve deterioration (SVD) is a significant concern in bioprosthetic aortic valves, particularly in patients with comorbidities.
• The Bentall-de Bono procedure, while effective, can present challenges for reoperation due to complex anatomy.
• Tissue valves with double sewing ring techniques are used to improve durability and facilitate potential future interventions.

Purpose of the Study:

• To report a case of successful aortic valve replacement in an elderly hemodialysis patient with SVD after a Bentall-de Bono operation.
• To evaluate the feasibility of reoperation in a high-risk patient with a previously implanted tissue valve using the double sewing ring technique.
• To discuss the implications of this case for managing SVD in complex patient populations.

Main Methods:

• A case report of an 89-year-old hemodialysis patient experiencing SVD of a tissue aortic valve implanted via a Bentall-de Bono operation.
• Surgical extraction of the degenerated bioprosthesis.
• Aortic valve replacement procedure performed on a high-risk patient.

Main Results:

• The degenerated bioprosthesis was removed with ease.
• Aortic valve replacement was successfully completed without any intraoperative or postoperative complications.
• The patient, despite being high-risk due to age and hemodialysis dependence, tolerated the reoperation well.

Conclusions:

• Reoperation for structural valve deterioration after a Bentall-de Bono operation with a tissue valve using the double sewing ring technique is feasible.
• This approach may offer a viable solution for managing SVD in elderly, high-risk patients.
• The findings suggest potential for improved long-term outcomes in patients requiring valve reintervention.
