New diagnostic pathways urgently needed. Protocol of PET Guidance I pilot study: positron emission tomography in suspected cardiac implantable electronic device-related infection.

Background: Cardiovascular implantable electronic device (CIED) infection is a complication of increasing incidence. We present a protocol of an observational case control clinical trial "Positron Emission Tomography Combined With Computed Tomography (PET CT) in Suspected Cardiac Implantable Electronic Device Infection, a Pilot Study - PET Guidance I" (NCT02196753).

Aim: The aim of this observational clinical trial is to assess and standardise diagnostic algorithms for CIED infections (lead-dependent infective endocarditis, generator pocket infection, fever of unknown origin) with PET CT in Poland.
