pubmed-article:18557156 | pubmed:abstractText | 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 mortality/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 1 year after the initial operation by aortic root replacement with resternotomy in addition to appropriate antibiotics. | lld:pubmed |
