‘Definite’ CIED clinical pocket/generator infection = generator pocket shows swelling, erythema, warmth, pain, and purulent discharge/sinus formation OR deformation of pocket, adherence and threatened erosion OR exposed generator or proximal leads
‘Definite’ CIED/IE = presence of either 2 major criteria or 1 major + 3 minor criteria
‘Possible’ CIED/IE = presence of either 1 major + 1 minor criteria or 3 minor criteria
‘Rejected’ CIED/IE diagnosis = patients who did not meet the aforementioned criteria for IE

B. Microorganisms consistent with IE from 2 separate blood cultures:
a. Viridans streptococci, Streptococcus gallolyticus (S. bovis), HACEK group, S. aureus; or
b. Community-acquired enterococci, in the absence of a primary focus
|
C. Microorganisms consistent with IE from persistently positive blood cultures:
a. ≥2 positive blood cultures of blood samples drawn >12 h apart; or
b. All of 3 or a majority of ≥4 separate cultures of blood (first and last samples drawn ≥1 h apart); or
c. Single positive blood culture for Coxiella burnetii or phase I IgG antibody titre >1:800

Imaging positive for CIED infections and/or IE |
D. Echocardiogram (including ICE) positive for:
a. CIED infection:
i. Clinical pocket/generator infection
ii. Lead-vegetation
b. Valve IE
i. Vegetations
ii. Abscess, pseudoaneurysm, intracardiac fistula
iii. Valvular perforation or aneurysm
iv. New partial dehiscence of prosthetic valve

E. [18F]FDG PET/CT (caution should be taken in case of recent implants) or radiolabelled WBC SPECT/CT detection of abnormal activity at pocket/generator site, along leads or at valve site
