title: [Comparison between definite endocarditis and possible endocarditis according to the Duke Criteria, in a monocentric study of 45 patients].
abstract: OBJECTIVE
  To compare definite endocarditis (DE) and possible endocarditis (PE) according to the Duke criteria, in a monocentric cohort of 45 patients.
  
  
  METHODS
  From the registers of the Cardiology Department and medical database of the hospital informatic department, 45 cases of endocarditis are colliged, 29DE and 16PE.
  
  
  RESULTS
  DE age is 66 years, PE age is 74 years, (p<0,02), 17 male (59%) in DE, eight in PE, 21 (72%) DE have a preexisting cardiopathy versus 15 (94%) PE, seven native valve and six prosthetic valve in PE, 11 native valve and nine prosthetic valve in DE. Twenty-six (90%) DE and 16 (100%) have fever, 14 (48%) DE and nine (56%) PE have a cardiac failure, one DE (3%) and 14 (87%) have no echographic sign of endocarditis (transthoracic echo or transthoracic and transesophagal echo) (p<0.001). Blood cultures are positive in 23DE (79%), and 14 (87%) PE (NS) Streptococcus and Enterococcus are the most common bacterial species (62%) in the two groups. Treatment duration is 64 days for DE and 43 days for PE, hospitalisation duration is 33 days for the DE and 27 days in PE.
  
  
  CONCLUSIONS
  PE group and DE group are similar concerning fever cardiac failure, preexisting cardiopathy, blood cultures and bacterial species. PE group is older than DE group, echography is more often negative in PE group. A patient with a preexisting valvulopathy and a septicemia without echographic sign of endocarditis is the most frequent clinical pattern in PE.
