Th e objec t of th e study was to follow pati en ts with en doca rditisassociated ab scess es in order to evalua te the clinical outcome with and without surgica l inte rve ntion. Tr an sesophageal echoca rdiogra phy su ccessfully displ ayed the locatio n and extent of abscess cavities in 14 patients (group Al with ao rt ic valve endocarditis. The infective process was limited to the perivalvul ar tissue in two. exte nde d int o th e asce nding ao rta in six. and included th e interve ntricula r se ptum, the right ventricular outflow tract. interat rial septum , an d/or mitra l valve a nnulus in six pat ien ts . The complication rate was significan tly higher in grou p A than in gro up B, which consist ed of 27 patients with proven signs of endoca rditis but without endocarditis-associated ab scesses. The compli cation rat es wer e embolic events 64 .3% in gro up A vs 29 .6% in group B, need for surgery in 64 .3% vs 18.5%, an d dea th in 50.0 % vs 3.7 %, respectively. The d ura tion of fever - as a marker of a n active infective pr ocess - before diagnosis an d the onset of adequate trea tmen t was significa ntly highe r in groupA than in group B (46 .7 ± 8.4 days vs 7.7 ± 2.6 da ys). Orga nism s wer e isolat ed in 71.4 % in groupA a nd in a ll pati en ts of grou p B. Stre ptococcal infections wer e noted in A in 54 .5% vs 44.4 % in B.. staphylococcal in 27.3% vs 40 .7 %. Initia l surgical rep air in 9 of 14 pati ents in A (64.3 %) included nine ao rtic valve an d one mitra l valve prost hesi s implanta tions , two aorti c valve-annulus reconstructive proc edures , one dacron patch closure, and three partial resections of the ao rta ascenden s with end-to-e nd a nas tomosis. Six pati ents (67.7 %) survived surgica l treatm ent. in contra st to only one of five (20 %) und ergoing medical tr eatment only. In groupB 18.5 % underwen t pla in valve replacement. which all pat ients survived; one patien t (3.7 %) who received med ical treat ment only died . Tr an sesophageal echocardiog ra phy allows a timely recognition of a bscess form a tion a nd progression a nd may permit ea rlier surgica l interventi on before widespre ad tissu e destruction occurs . Surge ry is then in a position to improve the outcome in patients with endoca rditis-a ssociated abscess es ; it de ma nds a diagnosis as ea rly as possible. because a delay in the onset of the ra py ma ndates more exte nsive su rgery with a higher risk than simpl e valve replacement.
