Belonging to the normal oral, gastrointestinal, and urogenital flora, is responsible for 1-2 % of all infective endocarditis (IE) cases. The manifestation of endocarditis may by atypical, without fever. Difficult to isolate pathogen requires special culture media. A 45-year-old female was admitted due to anemia and progressive weight loss (8 kg in 6 months). She had a history of benign mitral valve (MV) prolapse and non-stenotic bicuspid aortic valve (BAV). In echocardiography, large vegetations on MV and small vegetation on BAV were found. An enriched medium for fastidious pathogens was used. was identified using biochemical analysis with VITEK-2 Compact. In the fourth week of antibiotic therapy, she required urgent MV replacement due to MV regurgitation progression while vegetation on BAV disappeared. Although patient's frailty and underweight caused prolonged postoperative wound healing, she was transferred to rehabilitation in good conditions. No relapse of IE was observed during five-month follow-up.

Article Synopsis
  • Infective endocarditis (IE) is a serious condition with high mortality rates, especially in patients with abnormal heart valves like bicuspid aortic valves (BAV).
  • A 22-year-old female initially hospitalized for splenic infarction was later diagnosed with IE after presenting symptoms of acute toe ischemia and showing vegetations on her aortic valve.
  • The case highlights the importance of early detection and treatment of IE, especially in young patients, emphasizing the need to avoid anti-coagulation to prevent complications like embolic events.

Coarctation of the aorta (CoA) is a congenital heart defect that is associated with a bicuspid aortic valve (BAV), ascending aorta dilatation, intracerebral aneurysms, and premature atherosclerotic disease. The first presentation during late adulthood is rare and is frequently driven by late sequelae. Hypertrophic collateral arteries can develop aneurysms which are at risk for spontaneous rupture, however, treatment recommendations for these aneurysms are scarce.

Introduction: Accurate definition of stroke etiology is crucial, as this will guide effective targets for treatment. Both antiphospholipid antibody syndrome (APS) and infective endocarditis (IE) can be independent risk factors for ischemic stroke in young adults. When an embolic stroke occurs with IE and APS simultaneously, the origin of the embolic source is difficult to identify.

We report the case of a 53-year-old man with psoriatic arthritis, suffering from a malignant and recidivant myoepithelioma in his right axilla and arm, and undergoing two surgeries, with the last one being performed a month prior to actual admission. After the last surgery, he was admitted to hospital with fever without a source. After physical examination, laboratory tests, blood cultures and transthoracic and transesophageal echocardiography, he was diagnosed with infectious endocarditis (IE) on a bicuspid aortic valve (BAV) caused by (PA).
