A 59-year-old man with type 1 diabetes presented with heart failure. Echocardiography showed large vegetations on the mitral and aortic valves. Blood bacterial culture was positive for Staphylococcus warneri, a coagulase-negative staphylococcus (CoNS) family member. He was diagnosed with native valve endocarditis (NVE) induced by the resident bacteria and ultimately underwent double valve replacement. Retrospectively, slight laboratory data abnormalities and weight loss beginning four months before may have been signs of NVE. He had no history of immunosuppressive therapies or medical device implantation. Thus, CoNS can cause NVE after a long asymptomatic course in patients with poorly controlled diabetes.

Aims: Pulmonary regurgitation (PR) after reparative intervention for congenital heart disease has been studied extensively. However, the burden, distribution of causes, and outcome of PR in adults is unknown. The study aimed to evaluate the prevalence, types, and outcomes of moderate/severe PR in adults in the community setting.

Background: Daptomycin pharmacokinetics and pharmacodynamics data relative to higher doses in patients are necessary for clinical practice.
Objectives: A monocentric, prospective study that enrolled patients with a diagnosis of spp. infective endocarditis treated with daptomycin according to clinical practice, to evaluate the pharmacokinetics/pharmacodynamics of different daptomycin daily doses (group A: 8-10 and group B: 11-12 mg/kg).

Submitral aneurysm is a challenging and uncommon cardiac disease that is uniquely related to the posterior mitral valve leaflet. Awareness and prompt identification are vital because of the strong predilection for sudden fatal complications. Techniques and timing of surgical procedures are not standardized, especially in incidentally detected cases.

Purpose: Infective endocarditis (IE) is diagnosed using the Duke criteria, which were updated in 2023. In the Duke-ISCVID 2023 criteria, was recognised as a typical IE pathogen. This study investigates the impact of this change and compares the clinical characteristics of IE to IE caused by other pathogens.
