PURPOSE OF REVIEW: 18F-Fluorodeoxyglucose positron emission tomography/computed tomography is a well-established technique for diagnosis and management of a number of neoplastic conditions. However, in recent years the body of literature regarding its potential role in infectious diseases has progressively increased, with promising results. RECENT FINDINGS: So far 18F-fluorodeoxyglucose positron emission tomography/computed tomography has a well-established role and is recommended by guidelines only in a few settings, such as prosthetic valve endocarditis, vascular device infections, and chronic osteomyelitis...

AIMS: Adult congenital heart disease (ACHD) predisposes to infective endocarditis (IE). Surgical advancements have changed the ACHD population, whereas associated prosthetic material may constitute additional IE targets. We aimed to prospectively determine contemporary incidence, risk factors, and predictors of IE in a nationwide ACHD cohort, focusing on the presence of prosthetics. METHODS AND RESULTS: We identified 14 224 patients prospectively followed in the CONCOR ACHD registry (50...

OBJECTIVES: Propionibacterium acnes remains a rare cause of infective endocarditis (IE). It is challenging to diagnose due to the organism's fastidious nature and the indolent presentation of the disease. The purpose of this study was to describe the clinical presentation and management of P. acnes IE with an emphasis on the methods of diagnosis. METHODS: We identified patients from the Cleveland Clinic Infective Endocarditis Registry who were admitted from 2007 to 2015 with definite IE by Duke Criteria...

In patients with a small aortic root undergoing aortic valve replacement (AVR), the Freedom SOLO bioprosthesis may be the ideal prosthesis because of its stentless design and supra-annular implantation. This study investigated if the stentless Freedom SOLO has an advantage when compared with a stented bioprosthesis in patients with a small aortic root. From April 2005-July 2014, 269 consecutive patients underwent AVR with either a Freedom SOLO (n = 76) or Mitroflow (n = 193) bioprosthesis size 19mm or 21mm, respectively...

Aminoglycosides are a mainstay of treatment for enterococcal infective endocarditis. However, the benefit of adding aminoglycosides to cell wall-active agents after surgery is unclear. The aim of this study was to determine if adjunctive aminoglycoside treatment after surgery for enterococcal endocarditis leads to better outcomes. We included patients who underwent surgery for enterococcal endocarditis at our institution between July 2007 and July 2014. Treatment was defined as at least 1 dose of an aminoglycoside after surgery...

The brucellosis with multi-organ involvement in a patient with a history of the composite aortic graft (Bentall procedure) and Hepatitis B infection is rare. A 35-year-old man presented to us with fever and loss of consciousness. Four years ago, he was IDU and underwent cardiac surgery because of endocarditis. Recently lumbar spondylodiscitis was diagnosed. The Wright (1/320) and Coombs Wright tests (1/640) were positive. After CNS imaging, lumbar puncture was done. The CSF pleocytosis was lymphocyte dominant...

The case is presented of a 72-year-old male patient suffering from active infective aortic prosthetic endocarditis two months after emergency surgery with aortic valve implantation, and who underwent aortic arch reconstruction using a Dacron patch, due to the spontaneous post-procedural migration of a transcatheter-implanted aortic valve. The heart team considered transcatheter valve implantation (TAVI) due to the increased operative risk demonstrated by a EuroSCORE II of 10.9%, including chronic obstructive pulmonary disease (GOLD 3), cirrhosis (Child-B), esophageal varicose stage 2, chronic renal failure stage 3, and reduced left ventricular ejection fraction...

BACKGROUND: Despite being usually clinically silent, paravalvular leak can present with congestive heart failure (CHF) or haemolytic anemia. Here, the case is reported of a paravalvular leak presenting with CHF, complicated by new-onset severe hemolytic anemia after percutaneous closure with a large ventricular septal duct (VSD) occlude device. METHODS: A 57-year-old patient presented with infectious endocarditis of a native mitral valve with major mitral regurgitation and was submitted for mitral valvuloplasty...

We report a rare case of prosthetic valve fungal endocarditis caused by Lichtheimia, a subspecies of the order Mucorales. The patient experienced complicated prosthetic valve endocarditis less than 2 months after uneventful coronary artery bypass grafting (CABG) and 2 aortic valve replacements. Ultimately surgical management required aortic root replacement and lifelong antimicrobial agents. We believe this is the first case of fungal endocarditis caused by Lichtheimia.

The overuse of antibiotics and the emergence of antibiotic-resistant bacterial strains is a global concern. This concern is also of importance in terms of the oral microbiota and the use of antibiotics to deal with oral and dental infections. The aim of this paper is to review the current literature on the indications and use of antibiotics and to make recommendations for their prescription in endodontic patients. Odontogenic infections, including endodontic infections, are polymicrobial, and in most cases, the prescription of antibiotics is empirical...

BACKGROUND: Q fever, caused by the rickettsia Coxiella burnetii, is a worldwide zoonotic disease with both acute and chronic manifestations. Endocarditis is the principal chronic manifestation. Q fever can easily be mistaken for degenerative valve disease due to its indolent presentation, the fastidious nature of the organism (routine cultures are negative), and the absence of a typical echocardiographic and macroscopic appearance for endocarditis. Prosthetic valve failure, with associated morbidity and mortality, have been described following unrecognized infections...

Propionibacterium acnes is known to be a causative microorganism in low-grade and late prosthetic valve endocarditis. Here, the case is reported of a late, apparently culture-negative endocarditis of an aortic mechanical prosthesis, diagnosed to be caused by P. acnes after pan-bacterial polymerase chain reaction (PCR) on the explanted mechanical prosthetic valve. This endocarditis was complicated by an aortic root abscess; after surgical resection a ventricular septal defect (VSD) with overt right ventricular and multiple organ failure occurred...

Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

Nondiphtheria Corynebacterium species are often dismissed as culture contaminants, but they have recently become increasingly recognized as pathologic organisms. We present the case of a 48-year-old male patient on chronic prednisone therapy for rheumatoid arthritis with a history of mitral valve replacement with prosthetic valve. He presented with fever, dizziness, dyspnea on exertion, intermittent chest pain, and palpitations. Transesophageal echocardiography revealed two medium-sized densities along the inner aspect of the sewing ring and one larger density along the atrial surface of the sewing ring consistent with vegetation...

Prosthetic valve endocarditis (PVE) after transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) is a potential life threatening complication. Better understanding of the incidence, predictors, clinical presentation, diagnostic measures, complications and management of PVE may help improve TAVI long-term outcome. We report a case of TAVI-PVE in an 80-year-old high risk patient in whom SAVR was successfully performed. We have reviewed literature regarding TAVI-PVE.
