What this trial studies

This multicentric observational study aims to assess the impact of FDG-PET/CT imaging on the management of patients suspected of having native valve infective endocarditis (NVE). Participants will be recruited from six different healthcare centers, including two specialized cardiac centers and four tertiary care hospitals. The study will focus on patients classified as having possible infective endocarditis according to the modified Duke criteria and will evaluate how FDG-PET/CT influences clinical decision-making. The study will include adults who can provide informed consent and tolerate the PET/CT procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are suspected of having native valve infective endocarditis and are referred for FDG-PET/CT imaging.

Not a fit: Patients with prosthetic cardiac valves, those who are pregnant or breastfeeding, and individuals with a body mass index over 45 kg/m2 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the diagnostic accuracy and management strategies for patients with infective endocarditis.

How similar studies have performed: While the use of FDG-PET/CT in this context is gaining interest, this specific approach is relatively novel and has not been extensively tested in prior studies.
