Homograft aortic root replacement for complicated prosthetic valve endocarditis
Circulation
|September 1, 1984
Summary
Homograft aortic root replacement effectively treated prosthetic valve endocarditis and sepsis in ten patients. This surgical approach offers a viable alternative for managing complex aortic root infections.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Prosthetic Valve Endocarditis
Background:
- Late-onset prosthetic valve endocarditis (PVE) presents a significant challenge, often involving uncontrolled sepsis and aortic root abscesses.
- Destruction of the aortic ring by sepsis complicates management and increases surgical risk.
Purpose of the Study:
- To evaluate the efficacy of homograft aortic root replacement with coronary artery reimplantation in patients with active PVE, sepsis, and root abscesses.
- To assess the clinical and hemodynamic outcomes of this surgical technique.
Main Methods:
- Ten patients with severe PVE, sepsis, and aortic root abscesses underwent homograft aortic root replacement.
- Coronary arteries were reimplanted during the procedure.
- Patients were followed for 6 to 132 months postoperatively.
Main Results:
- Two perioperative deaths occurred.
- Necrotizing endocarditis was cured in all eight survivors.
- Two survivors experienced biological valve malfunction; six had excellent clinical and hemodynamic results.
Conclusions:
- Homograft aortic root replacement is a feasible surgical option for selected patients with active PVE, sepsis, and aortic ring destruction.
- The procedure successfully eradicates infection and reconstructs the aortic root, offering an alternative to conventional methods.
