Objective: To explore the relationship between infective endocarditis (IE) and stroke. Methods: The clinical data of patients diagnosed with IE from January 2003 to December 2017 in Beijing Anzhen Hospital Affiliated to Capital Medical University were retrospectively analyzed. Results: A total of 861 patients (mean age: 40.79 ± 16.27 [SD]) with IE was recruited. Vegetations were confirmed in 97.32% of all the patients, among whom 296 were diagnosed with congenital heart disease and another 53 with rheumatic valvular disease. The most common pathogens were Streptococcus, Staphylococcus, and various types of fungi (13.12, 7.31, and 1.16% respectively). Out of the 138 patients diagnosed with stroke, 101 cases were of ischemic stroke, 23 cases were of hemorrhagic stroke, and 12 cases were of concurrent ischemic and hemorrhagic stroke. There were 31 patients who had infarction lesions in more than 2 vascular systems. The mean age of stroke patients was significantly higher than that of patients without stroke (45.76 ± 17.88 vs. 39.83 ± 15.77, p = 0.000). The incidence of mitral valve vegetation (57.24 vs. 43.01%, p = 0.002), atrial fibrillation (4.34 vs. 1.38%, p = 0.018), fungal infection (2.89 vs. 0.83%, p = 0.038) in patients with stroke was significantly higher than those without stroke. Mitral valve vegetation (OR 1.648; 95% CI 1.113–2.442) and age (OR 1.019; 95% CI 1.007–1.032) were independent risk factors for stroke in IE patients. Stroke increased the risk of hospital deaths (OR 7.673 95%CI 3.634–16.202). Conclusion: Stroke is a common complication of IE. Mitral valve vegetation and old age may incerease the risk of stroke in patients with IE.

We report the first case of infective endocarditis caused by Paenibacillus provencensis. A mitral valve vegetation was incidentally discovered by intraoperative transoesophageal echocardiography in a 70-year-old woman undergoing aortic valve replacement. The precise identification of the causative agent was by means of genotypic characterisation with 16S rDNA gene sequencing. The patient was successfully treated with a 6-week course of antibiotics postoperatively, following debridement of the valve vegetation.

Transesophageal echocardiography is mandatory if you do suspect infective endocarditis. By approaching via a small right thoracotomy, vegetectomy and mitral valvuloplasty following severe mediastinitis were successfully accomplished without any complications.

The manifestation of infective endocarditis often resembles vasculitis. Approximately one in five infective endocarditis cases are referred initially to a nephrologist because of abnormal renal function or abnormal urinalysis; therefore, infection should be ruled out before diagnosing vasculitis.A case involving a patient with infective endocarditis who presented with migrating skin lesions, renal infarction and multiple pseudoaneurysms is reported. Echocardiography revealed mitral valve vegetation and viridans streptococci were identified in peripheral blood cultures. Although mitral valve annuloplasty and an aneurysm ligation operation were performed with proper antibiotic treatment, the remaining mycotic aneurysm progressed and caused neurological complications. The patient was cured completely after reoperation.

Genotype V

Mitral valve aneurysm (MVA) is a rare but life-threatening valvular pathologic entity most commonly associated with infective endocarditis (IE) of the aortic valve (AV). We describe a diabetic patient with ruptured anterior MVA secondary to capsular genotype V Streptococcus agalactiae (GBS) harboring novel ST1656 IE without AV involvement. Our patient presented with manifestations of various serious systemic and intracardiac complications, requiring early surgery, but ultimately died from non-cardiogenic causes. This case emphasizes the importance of treating MVA as a dangerous sequela of IE, of performing transesophageal echocardiography to make its accurate diagnosis and institute early surgical intervention, and of considering GBS as a rare but important causative agent of IE in elderly patients with comorbidities.
