Prosthetic valve thrombosis (PVT) refers to the presence of non infective material in valvular apparatus, interfering with its function. It is a potentially fatal complication of valvular replacement surgery. Treatment options include surgery, fibrinolysis and anticoagulation optimisation. The authors present the case of a young man, carrier of an aortic prosthetic mechanical valve, who didn't take his anticoagulant medicine, admitted for an acute obstructive PVT, with evidence of a large thrombotic mass on the aortic valve (> 1cm(2)). The patient refused surgical treatment and eventually presented a complete resolution of the acute PVT with anticoagulation optimisation.

Introduction: Prosthetic valve endocarditis following aortic root replacement (ARR) typically necessitates redo-ARR, which involves complete graft removal, extensive aortic root dissection, and coronary reimplantation. This highly invasive procedure carries substantial surgical risk, including high operative mortality. In select high-risk patients without evidence of prosthetic graft infection, alternative surgical strategies may reduce procedural complexity and improve outcomes.

Complete detachment of the aortic root following a Bentall procedure is an exceptionally rare complication. The vast majority of reported cases are secondary to prosthetic valve endocarditis or underlying vasculitis. Currently, the most reliable treatment for aortic root dehiscence-particularly in the context of prosthetic valve endocarditis-is repeat root replacement, typically via a second Bentall procedure or with the use of a homograft or allograft.

We report two cases of Elizabethkingia-related infective endocarditis, highlighting key risk factors such as prosthetic valve replacement. These cases underscore the need to consider endocarditis in the setting of persistent or recurrent bacteremia. Diagnosis proved challenging and required multiple imaging modalities, with positron emission tomography (PET) scan providing critical value when echocardiography was non-contributory.

Background: Infective endocarditis (IE) with irreversible structural damage has high mortality despite conventional surgery. Heart transplantation (HTx) remains underused in active IE owing to guideline limitations and historical contraindications.
Case Summary: A 61-year-old man with recurrent prosthetic valve IE (aortic/tricuspid vegetations, perivalvular abscesses, and coronary embolism) developed cardiogenic shock.

Background: Diagnosing infective endocarditis (IE) is a significant challenge. This study aimed to compare the diagnostic performance of the 2015 and 2023 European Society of Cardiology (ESC) and the 2023 International Society for Cardiovascular Infectious Diseases (ISCVID) Duke clinical criteria in a cohort of patients with suspected IE and intracardiac prosthetic material.
Methods: This retrospective study was conducted at 2 Swiss University Hospitals (2014-2024).
