OBJECTIVE: Infection of valved aortic grafts is a rare entity whose diagnosis remains challenging. Positron emission tomography (PET)/CT has become a criterion for the diagnosis of infective endocarditis (IE) in prosthetic valves, but its role on ascending aortic graft infections remains unclear. This study aims to assess the diagnostic value of PET/CT in patients with valved aortic graft infection. METHODS: 12 episodes with a valved aortic graft who had undergone a PET/CT due to suspicion of IE were prospectively included (group I) and compared with five controls free of infection who underwent PET/CT for other reasons (group II)...

Aerococcus species were first described in 1953. They have been previously described as the causative agent of urinary tract infections in the elderly but rarely the causative agent for severe infections. However, there are very few cases reported in the pediatric population. To our knowledge, we report the first case of an adolescent with infective endocarditis caused by Aerococcus urinae.

BACKGROUND: Cardiac disease is 1 of the major causes of maternal mortality. We studied pregnancy outcomes in women with rheumatic mitral valve disease. METHODS: The Registry of Pregnancy and Cardiac Disease is an international prospective registry, and consecutive pregnant women with cardiac disease were included. Pregnancy outcomes in all women with rheumatic mitral valve disease and no prepregnancy valve replacement is described in the present study (n=390). A maternal cardiac event was defined as cardiac death, arrhythmia requiring treatment, heart failure, thromboembolic event, aortic dissection, endocarditis, acute coronary syndrome, and hospitalization for other cardiac reasons or cardiac intervention...

BACKGROUND: Consensus guidelines for prosthesis selection in infective endocarditis recommend bioprosthetic or mechanical valve replacement based on life expectancy and comorbidity. However, contemporary outcome data are limited to institution series. METHODS: The outcomes of 3,447 patients identified from mandatory discharge databases in California and New York states who had either primary isolated mitral (n=1603) or aortic (n=1,844) valve replacement for active endocarditis between 1998 and 2010, were compared according to whether they received bioprosthetic (n=1,673, 48...

Gemella is a genus of Gram-positive bacteria found in the digestive tract of humans. They rarely cause systemic illness but have been recently implicated in several serious infections. We report infective endocarditis caused by Gemella bergeri in a 23-year-old with a bicuspid aortic valve status post-intervention in infancy.

Acquired intracardiac left-to-right shunts are rare occurrences. Chest trauma and myocardial infection are well-known causes of acquired ventricular septal defect (VSD). There have been several case reports describing left ventricle to right atrium shunt after infective endocarditis (IE). We present here a patient found to have an acquired VSD secondary to IE of the aortic and tricuspid valves in the setting of a known bicuspid aortic valve. This is the first case reported of acquired VSD in a pediatric patient in the setting of IE along with literature review of acquired left-to-right shunts...

The cytochrome P450 is a superfamily of isoenzymes that are responsible for the metabolism of many drugs. Significant changes in pharmacokinetics and drug interactions may be due to induction of hepatic cytochrome P450 enzymes. Rifampicin is a common inducer of CYP3A4. We report a case of a 57-year-old woman who was suspected for endocarditis and therefore treated with rifampicin. Due to previous mechanical aortic valve replacement, she also received phenprocoumon for anticoagulation. Although continuing anticoagulant therapy, antibiotic coadministration led to normal international normalised ratio (INR) level...

BACKGROUND: Infective endocarditis (IE) is still a condition with high mortality and morbidity, especially in the elderly, and in patients with prosthetic valves. The concept of "time-to-therapy" plays a key role for the prompt management of IE and related complications, and the currently available multimodality imaging may play a key role in this setting. Myocardial ischemia due to extrinsic coronary compression from an aortic abscess is an extremely rare condition where the optimal therapeutic strategy has not been defined yet...

OBJECTIVES: Given the paucity of available literature, we sought to evaluate the mechanisms of tricuspid regurgitation and the outcomes of tricuspid valve surgery in the presence of permanent pacemakers. METHODS: We retrospectively reviewed the records of 622 adult patients who underwent tricuspid valve surgery in the presence of permanent pacemakers between January 1993 and December 2013. Those with prosthetic tricuspid valve or tricuspid valve endocarditis and those undergoing concomitant heart transplant were excluded (n = 23)...

REVIEW
Joseph L Blackshear
Gastrointestinal bleeding with severe aortic stenosis was originally described in the 1950s by Heyde, although for years, the association was debated. Further discovery of mechanisms and the ubiquity and severity of acquired von Willebrand syndrome in the left ventricular assist device therapy have removed any doubts. At this time, gastrointestinal bleeding from intestinal angiodysplasia in patients with turbulence-related proteolysis of the highest molecular weight multimers of von Willebrand factor is now known to occur in patients with aortic stenosis, and also subaortic obstruction and associated mitral insufficiency in hypertrophic cardiomyopathy, isolated mitral and aortic insufficiency, endocarditis, and in patients with prosthetic valve dysfunction, either from stenosis or insufficiency...

BACKGROUND: In the last decades, probiotics have been widely used as food supplements because of their putative beneficial health effects. They are generally considered safe but rare reports of serious infections caused by bacteria included in the definition of probiotics raise concerns on their potential pathogenic role in patients with particular predisposing factors. Patients with hereditary hemorrhagic telangiectasia (HHT) are exposed to infections because of telangiectasias and arteriovenous malformations (AVMs)...

RATIONALE: Fever of unknown origin (FUO) can be determined by different conditions among which infectious diseases represent the main cause. PATIENT CONCERNS: A young woman, with a history of aortic stenosis, was admitted to our unit for a month of intermittent fever associated with a new diastolic heart murmur and splenomegaly. Laboratory tests were negative for infectious screening. The total body computed tomography (CT) scan excluded abscesses, occulted neoplasia, or lymphadenopathy...
