BACKGROUND: Treatment of prosthetic aortic valve endocarditis and native aortic valve endocarditis with abscess formation is associated with high mortality and morbidity. Aortic root replacement with a freestanding aortic homograft is an attractive alternative. We report outcome and quality of life after homograft replacement for infective endocarditis. METHODS: Sixty-two patients with infective prosthetic valve endocarditis (n = 31) or native valve endocarditis with abscess (n = 31), operated with homograft replacement were included. Thirty-day mortality, severe operative complications (dialysis, stroke, pacemaker implantation, myocardial infarction, and prolonged mechanical ventilation), midterm survival, reoperations, and quality of life were assessed after a mean follow-up of 37 ± 11 months. RESULTS: Nine patients (15%) died within 30 days and 22 patients (35%) had severe perioperative complications. Preoperative and perioperative variables univariately associated with early mortality were higher (Cleveland Clinic risk score [p = 0.014], extracorporeal circulation time [p = 0.003], prolonged inotropic support [p = 0.03], reoperation for bleeding [p = 0.01], and perioperative myocardial infarction [p < 0.001].) Cumulative survival was 82%, 78%, 75%, and 67% at one, three, five, and ten years, respectively. One patient was reoperated due to recurrence of endocarditis nine months after surgery and one after five years due to homograft failure. Quality of life, as assessed by the 36 item short-form health survey scales for physical and mental health, was not significantly different to an age-matched and gender-matched healthy control group. CONCLUSIONS: Severe acute aortic endocarditis treated with homograft replacement is still associated with a substantial early complication rate and mortality. Long-term survival and quality of life are satisfactory in patients surviving the immediate postoperative period.
