Homograft aortic valve and root replacement for severe destructive native or prosthetic endocarditis

Ten male patients with a mean age of 57.5 years (range 27-75 years) underwent homograft aortic valve or root replacement for destructive aortic valve endocarditis. Six patients had native valve endocarditis (one with associated native mitral valve endocarditis) and four had prosthetic valve endocarditis (one with associated prosthetic mitral endocarditis). Causative organisms were Streptococci in six patients, Staphylococci in one, Q fever in one and no organisms were isolated in the remaining two patients. All the patients were operated while on antibiotics (mean lengths of treatment 13 days; range 2-42). The main indication for surgery was cardiogenic shock in five patients, progressive cardiac failure in four patients and uncontrolled sepsis in one patient. Operative procedures involved homograft aortic root replacement with coronary reimplantation (seven patients; associated prosthetic mitral valve replacement in one patient), infracoronary homograft aortic valve replacement (three patients) and a number of other procedures were performed to reconstruct the disrupted cardiac anatomy. Patients were followed up for a mean of 13.2 months (range 2- 21). One patient died 4 months postoperatively of an unrelated cause; all the others are asymptomatic with no evidence of recurrent endocarditis. We conclude that homograft aortic valve or root replacement is an effective method of managing destructive aortic valve endocarditis.
