Summary
Reoperative aortic root replacement using homografts offers favorable outcomes for infected prostheses. Synthetic graft material does not negatively impact results, ensuring successful aortic repair.
Area of Science:
- Cardiovascular Surgery
- Infectious Disease Management
- Prosthetic Valve Surgery
Background:
- Infected aortic root replacement (ARR) prostheses present a significant clinical challenge.
- Reoperation for these infections requires careful consideration of graft materials and outcomes.
Purpose of the Study:
- To evaluate freedom from reinfection after surgery for infected aortic root replacement (ARR).
- To assess the impact of using synthetic materials during reoperation for infected ARR.
Main Methods:
- Retrospective review of adult patients undergoing surgery for infected composite aortic root prostheses.
- Analysis of perioperative outcomes, late survival, and reinfection rates.
Main Results:
- Fifteen patients underwent reoperation, with most receiving homograft reconstruction.
- Freedom from reinfection was favorable, with synthetic graft use showing no adverse impact.
- Positive blood cultures post-redo ARR and multiple sternotomies were associated with lower freedom from reinfection.
Conclusions:
- Homografts are a viable option for replacing infected aortic root prostheses.
- Synthetic materials can be safely used in conjunction with homografts without compromising outcomes.
