Insights
Diagnosing prosthetic valve endocarditis is challenging. 18F-FDG PET/CT significantly improves diagnostic accuracy in suspected cases with inconclusive echocardiography, aiding timely treatment.
Area of Science:
- Cardiology
- Nuclear Medicine
- Infectious Diseases
Background:
- Prosthetic valve endocarditis (PVE) presents diagnostic challenges due to limitations of modified Duke criteria and echocardiography.
- Delayed diagnosis of PVE increases patient morbidity and mortality rates.
Abstract:
Prosthetic valve endocarditis is a major diagnostic challenge in clinical practice, due to the lower sensitivity of the modified Duke criteria and a higher percentage of cases with negative or inconclusive echocardiography results. The delay in establishing medical and surgical treatment increases the morbidity/mortality rate. New imaging techniques and 18F-FDG PET/CT in particular have meant a significant advance in cases of high clinical suspicion and negative or inconclusive echocardiography, increasing the overall sensitivity of the modified Duke criteria. We report the case of a male patient with prosthetic valve endocarditis, where 18F-FDG PET/CT provided the diagnostic key, determining the origin of the endocarditis and avoiding treatment delay.

Endocarditis I: Introduction
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
