Table 2 Presence of the modified Duke criteria among the TOE examinations

Abbreviations: bAVR bioprosthetic aortic valve replacement, bMVR bioprosthetic mitral valve replacement, CIED Cardiovascular implantable electronic device, CoNS Coagulase negative staphylococci, CT Computed tomography, FDG Fluorodeoxyglucose, IE Infective endocarditis, mAVR mechanical aortic valve replacement, mMVR mechanical mitral valve replacement, PET Positron emission tomography, TAVR Transcatheter aortic valve replacement, TOE Transoesophageal echocardiography
  2. a Percentage of the examinations for each row among all examinations
  3. b Percentage of the examinations with positive TOE among the examinations for each row. The information above is based on the examinations, not the patients, which means that if one patient underwent two (or more) TOE examinations positive for abscess, then two examinations positive for abscess was added to the table
