Why the study?
Infective endocarditis poses diagnostic challenges, and relying on echocardiography alone may lead to overlooking endocarditis of a pulmonary homograft.
Does the use of cardiac CTA and FDG-PET/CT improve the diagnosis of right-sided endocarditis in patients with a pulmonary homograft compared to echocardiography alone?

Does the use of cardiac CTA and FDG-PET/CT improve the diagnosis of right-sided endocarditis in patients with a pulmonary homograft compared to echocardiography alone?
Cardiac CTA and FDG-PET/CT are valuable imaging modalities for diagnosing right-sided endocarditis, particularly in patients with prior surgical interventions like a pulmonary homograft where echocardiography may be insufficient.
BACKGROUND: Infective endocarditis (IE) poses many clinical and diagnostic challenges. Echocardiography is regarded as the imaging modality of choice for the diagnosis of IE, and plays a key role in both the diagnosis and management of endocarditis. We report on a case in which one could have overlooked an endocarditis of a pulmonary homograft if one had relied on echocardiography alone. CASE SUMMARY: F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) and cardiac computed tomography angiogram (cardiac CTA). Both imaging modalities showed large vegetations attached to the pulmonary homograft. DISCUSSION: F-fluorodeoxyglucose positron emission tomography-computed tomography imaging to assess valves in pulmonary position, especially in those whom have had prior surgical intervention at this location.
