Summary
Aortic root replacement after prior aortic surgery is a viable option, demonstrating acceptable morbidity and mortality. This procedure addresses various complex aortic conditions effectively.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Context:
- Review of ten patients undergoing aortic root replacement following previous operations on the ascending aorta and/or aortic valve.
- Initial operations included aortic valve replacement, ascending aorta replacement, Bentall operation, and aortic valve repair.
- Reoperations were indicated for ascending aortic aneurysm, annulo-aortic ectasia, and complex conditions like dissection and endocarditis.
Purpose:
- To evaluate the outcomes of aortic root replacement in patients with a history of prior aortic or aortic valve surgery.
- To assess the safety and efficacy of using mechanical valved composite grafts for aortic root reconstruction in this specific patient cohort.
Summary:
- Ten patients underwent aortic root replacement using mechanical valved composite grafts.
- Indications for reoperation included aneurysms, annulo-aortic ectasia, dissection, and prosthetic valve endocarditis.
- One patient died from sepsis and ventricular fibrillation post-reoperation for endocarditis; five patients experienced nine complications.
Impact:
- Aortic root replacement in this complex patient group can be performed with acceptable morbidity and mortality rates.
- The study highlights the feasibility of reoperative aortic root surgery for diverse pathological findings.
- Findings contribute to understanding the risks and benefits of repeat aortic root interventions.
