BACKGROUND Endocarditis is a common complication in Staphylococcus aureus bacteremia (SAB). We compared risk factors, clinical manifestations, and outcome in a large, prospective cohort of patients with S. aureus endocarditis in injection drug users (IDUs) and in nonaddicts. METHODS Four hundred and thirty consecutive adult patients with SAB were prospectively followed up for 3 months. Defini...

acinetobacter lwoffii, an important nosocomial pathogen, is a gram-negative aerobic bacillus that is a component of the normal flora on the skin, oropharynx, and perineum of about 20-25% of healthy individuals. we herein present a case of a 66-year-old man with combined mitral and aortic valve endocarditis associated with multi-drug resistance acinetobacter lowffii bacteremia.

Infective endocarditis continues to be a life-threatening disease despite the availability of antimicrobial agents.' Even with successful antibiotic treatment, death in intractable heart failure is common because of aortic valve destruction. Furthermore, with the increased scope of cardiac surgical procedures, one of the most serious causes of postoperative failure is infection upon prosthetic ...

UNLABELLED SummaryIn intravenous drug abusers, infective endocarditis usually involves right-sided valves, with Staphylococcus aureus being the most common etiologic agent. We present a patient who is an intravenous drug abuser with left-sided (aortic valve) endocarditis caused by Enterococcus faecalis who subsequently developed an anterior mitral valve aneurysm, which is an exceedingly rare co...

Forty-two cases of bacterial endocarditis with pathologic confirmation are reviewed. Infection was restricted to one or both left-sided valves in 31 cases, right-sided valves in five cases, and valves in both sides of the heart in six cases. In those specimens available for review, underlying valvular disease was identifiable in 24 of 38 cases (63%). The common underlying diseases, in order of ...

BACKGROUND Granulomas caused by Mycobacterium Tuberculosis have been observed at autopsy in the heart, pre-dominantly in the myocardium and endocardium, but rarely involving the coronary vessels and valvular structures. Mycobacterium tuberculosis valvular endocarditis is extremely rare, with most reports coming from autopsy series. CASE PRESENTATION We report the case of a 17 year old immunoc...

In the last 50 years, the incidence of infective endocarditis (IE) has remained between 2 and 6 per 100.000 individuals in the general population per year and its mortality has fluctuated between 10% and 30%, depending on the type of pathogen. Historically, chronic rheumatic heart disease had being the primary risk factor for IE but in the last years, new at-risk groups have emerged like indivi...

To describe the profile of left-sided polymicrobial endocarditis (PE) and to compare it with monomicrobial endocarditis (ME).Among 1011 episodes of left-sided endocarditis consecutively diagnosed in 3 tertiary centers, between January 1, 1996 and December 31, 2014, 60 were polymicrobial (5.9%), 821 monomicrobial (81.7%), and in 123 no microorganism was detected (12.2%). Seven patients (0.7%) we...
