Background -Invasive dental treatments (IDTs) can yield temporary bacteremia and has therefore been considered a potential risk factor of infective endocarditis (IE). It is hypothesized that, through the trauma caused by IDTs, bacteria gain entry to the bloodstream and may attach to abnormal heart valves or damaged heart tissue, giving rise to IE. However, the association between IDTs and IE remains controversial. The aim of this study is to estimate the association between IDTs and IE. Methods -The data in this study were obtained from the Health Insurance Database in Taiwan...

BACKGROUND: Surgical treatment of complicated aortic valve endocarditis often is challenging, even for experienced surgeons. We aim at demonstrating a standardized surgical approach by stentless bioprostheses for the treatment of aortic valve endocarditis complicated by paravalvular abscess formation. METHODS: Sixteen patients presenting with aortic valve endocarditis (4 native and 12 prosthetic valves) and paravalvular abscess formation at various localizations and to different extents were treated by a standardized approach using stentless bioprostheses...

Staphylococcus aureus bacteraemia (SAB) is a common and severe disease. In 2012, a structured bedside consultation (SBC) was introduced at Rijnstate Hospital. We analysed the effect of this SBC on the overall survival of patients with SAB and the effect on the diagnostic workup. We performed a retrospective cohort study, including all patients over 18 years with SAB from 2009 until 2017. The cases preceding versus those after implementation of SBC in 2012 were compared. In total, 613 episodes of SAB were analysed: 234 cases before and 379 cases since SBC...

Staphylococcus aureus infective endocarditis (SaIE) is a severe complication of S. aureus bacteremia (SAB) occurring in up to 22% of patients. Bacterial genetic factors and host conditions for SaIE have been intensely studied before; however, to date no study has focused on predisposing host genetic factors to SaIE. The present study aimed to identify genetic polymorphisms associated with SaIE by a Genome-Wide Association Study (GWAS) of 67 patients with definite native valve SaIE (cases) and 72 matched native valve patients with SAB but without IE (controls)...

Although Streptococcus anginosus constitutes a proportion of the normal flora of the gastrointestinal and genital tracts, and the oral cavity, it has been reported that S. anginosus infection could be closely associated with abscesses at various body sites, infective endocarditis, and upper gastrointestinal cancers. The colonization in an acidic environment due to the aciduricity of S. anginosus could be the etiology of the systemic infection of the bacteria. To elucidate the aciduricity and acid tolerance mechanisms of the microbe, we examined the viability and growth of S...

Streptococcus gallolyticus subsp. gallolyticus Sgg (formerly known as S. bovis type I) is the main causative agent of septicemia and infective endocarditis (IE) in elderly and immunocompromised persons. It belongs to the few opportunistic bacteria, which have been strongly associated to colorectal cancer (CRC). A literature survey covering a period of 40 years (1970-2010) revealed that 65% of patients diagnosed with an invasive Sgg infection had a concomitant colorectal neoplasia. Sgg is associated mainly with early adenomas and may thus constitute an early marker for CRC screening...

Congenital heart disease (CHD) is one of the most common risk factors for infective endocarditis. However, it is rare to find a CHD patient complicated by isolated pulmonary valve endocarditis. Here, we report an adult patient with congenital heart disease complicated by native pulmonary valve endocarditis who underwent a mechanical valve replacement. We also review previous literature to examine key points in the treatment of such patients.

Infective endocarditis (IE) during pregnancy and subsequent cardiac surgery are rare and associated with a high risk of mortality for the mother and fetus. It is difficult to determine the right time for cardiac intervention when IE is diagnosed early in pregnancy. A 33-year-old previously healthy woman in the 11th week of pregnancy was diagnosed with IE and underwent surgical intervention. The cardiopulmonary bypass settings and the anesthetic drugs were carefully chosen. Although she was in good health, while being discharged, the fetus did not survive...

OBJECTIVES: It is known that patients surviving infective endocarditis have a poor long-term prognosis; however, few studies have addressed the long-term causes of death in patients surviving the initial hospitalization. METHODS: Using Danish administrative registries, we identified patients admitted to a hospital with 1st time infective endocarditis in the period from January 1996 to December 2014, who were alive at the time of discharge. The study population was categorized into (i) patients undergoing medical therapy only and (ii) patients undergoing surgical and medical treatment...

Rat bite fever due to Streptobacillus moniliformis induces typical but not pathognomonic clinical signs, such as local purulent wound infection followed by maculopapular exanthema, myalgia as well as purulent joint infections. Severe complications, such as osteomyelitis and endocarditis are possible. it seems that this infection is rarely diagnosed but this infection could be much more common because the final diagnostic proof is difficult to achieve. Firstly, the culture of these bacteria is critical because the bacteria are fastidious and secondly the exact differentiation of the isolates is hardly possible by standard laboratory methods...

This case describes an unusual presentation of prosthetic valve endocarditis: an acute coronary syndrome. A 67-year-old gentleman presented with cardiac sounding chest pain on a background of a short history of night sweats, weight loss and general malaise. Four months previously he had undergone bio-prosthetic aortic valve replacement for severe aortic stenosis and single vessel bypass grafting of the obtuse marginal. Whilst having chest pain his ECG showed infero-lateral ST depression. Early coronary angiography revealed a new right coronary artery lesion that was not present prior to his cardiac surgery...
