Blood culture-negative endocarditis is common in Algeria. We describe the etiology of infective endocarditis in this country. Samples from 110 cases in 108 patients were collected in Algiers. Blood cultures were performed in Algeria. Serologic and molecular analysis of valves was performed in France. Infective endocarditis was classified as definite in 77 cases and possible in 33. Causative agents were detected by blood cultures in 48 cases. All 62 blood culture-negative endocarditis cases were tested by serologic or molecular methods or both. Of these, 34 tested negative and 28 had an etiologic agent identified. A total of 18 infective endocarditis cases were caused by zoonotic and arthropodborne bacteria, including Bartonella quintana (14 cases), Brucella melitensis (2 cases), and Coxiella burnetii (2 cases). Our data underline the high prevalence of infective endocarditis caused by Bartonella quintana in northern Africa and the role of serologic and molecular tools for the diagnosis of blood culture-negative endocarditis.

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).

Among 3127 episodes of suspected infective endocarditis, the 2023 Duke-International Society for Cardiovascular Infectious Diseases clinical criteria showed an accuracy of 90% for infective endocarditis diagnosis. A new heart murmur was present in 690 (22%) episodes. Excluding imaging and surgical findings decreased the accuracy to 73%, while using the physical examination criterion slightly improved the accuracy to 78%.

The Y-incision aortic annular enlargement (AAE) has been established as a safe and effective technique for upsizing the aortic annulus by 3 to 4 valve sizes. However, concerns have been raised regarding its technical complexity during reoperations, particularly given the extensive enlargement of the aortic annulus and root. We present a case of reoperative aortic valve replacement after previous Y-incision AAE for prosthetic valve endocarditis and aortic root abscess.
