Pilot study to evaluate the accuracy of cardiac PET/CT with [68Ga]Ga-PentixaFor in the diagnosis of three clinical entities of acute myocarditis
Summary description of the study
The project aims to study the effectiveness of nuclear imaging PET/CT using a new radiopharmaceutical product, [68Ga]Ga-PentixaFor. We want to investigate whether this single examination provides similar information on the presence of cellular markers of inflammation of the heart muscle, compared to those collected by the multiple standard follow-up examinations of your disease. This new product is not currently approved in Switzerland.
(BASEC)
Intervention under investigation
Participation in the study consists of a PET/CT examination with [68Ga]Ga-PentixaFor: the injection of the radiopharmaceutical product is followed by a one-hour rest period and the acquisition of images for about 25 minutes.
All patients will have the same PET/CT imaging with [68Ga]Ga-PentixaFor.
The standard follow-up and standard examinations related to the pathology will be carried out in a standard manner and will differ by patient group, being adapted to each pathology.

Disease under investigation
Acute myocarditis: patients in follow-up during their first year post heart transplantation OR patients with clinical suspicion of cardiac sarcoidosis OR patients with clinical suspicion of immunotherapy-induced myocarditis
(BASEC)
- signature of consent - aged ≥ 18 years - patients in the first year following heart transplantation (group I), patients with suspected cardiac sarcoidosis based on clinical findings (group II) and patients with immunotherapy-induced myocarditis (group III) - standard follow-up in the cardiology department of CHUV (BASEC)
Exclusion criteria
- claustrophobia - documented myocardial ischemia by non-invasive testing or coronary angiography - unstable clinical conditions - pregnant or breastfeeding women - women with intent to become pregnant during the study (BASEC)
