    Abstract:
    Aortic valve abscesses (AVAs) are a devastating complication of aortic valve endocarditis. Over 8 years, 25 patients were diagnosed with AVA by transesophageal echo (TEE). Management and outcomes were then analyzed. Eleven (44%) AVAs involved prosthetic valves, and 6 (24%) occurred in congenitally malformed valves. Twenty patients (80%) underwent surgical intervention; the rest were treated medically. Eleven (44%) of the patients died [6 (30%) surgery patients and all the medical patients]. Eight of 11 (73%) patients who died were culture positive for Staphylococcus aureus. All patients with congenitally malformed aortic valves underwent surgical intervention and survived. We conclude that: (1) despite advances in therapy and diagnosis, patients with AVAs have a high mortality rate; (2) prognosis with AVA is especially poor when S aureus is the infectious organism; (3) patients with AVAs in congenitally malformed valves have a great outcome with surgery; (4) patients treated medically have a very poor prognosis; earlier identification by TEE may be critical to improving survival.
