Annular abscesses are serious complications of infectious native and prosthetic valve endocarditis. In this patient, we isolated Stenotrophomonas maltophilia, a rare cause of subaortic abscess with high monality/morbidity rates although virulent gram-positive cocci, S. Aureus in particular, have been the most commonly isolated agents. We treated this case of endocarditis and the subannular abscess observed I year after the initial operation by aortic root replacement with resternotomy in addition to appropriate antibiotics.
