Multimodality Imaging in Infective Endocarditis: An Imaging Team Within the Endocarditis Team.

Multimodality Imaging in Infective Endocarditis: An Imaging Team Within the Endocarditis Team. Circulation. 2019 Nov 19;140(21):1753-1765 Authors: Erba PA, Pizzi MN, Roque A, Salaun E, Lancellotti P, Tornos P, Habib G Abstract Infective endocarditis (IE) is a complex disease with cardiac involvement and multiorgan complications. Its prognosis depends on prompt diagnosis that leads to an aggressive therapeutic management combining antibiotic therapy and early cardiac surgery when indicated. However, IE diagnosis always poses a challenge, and echocardiography remains diagnostically imperfect in cases of prosthetic valve IE or cardiac implantable electronic device infection. In recent years, other imaging modalities (computed tomography, magnetic resonance imaging, nuclear imaging) have experienced significant technical improvements, and their application to the detection of cardiac and extracardiac IE-related lesions seems to be a strategic way forward in the management of patients with suspected IE. However, the scientific evidence in the literature remains limited; current guidelines address the use of the multimodality imaging in the field of IE with caution; the incremental value of each technique and their combinations is debated; and their use varies across countries. Despite these limitations, healthcare providers and surgeons should be aware of the possibilities offered by the multimodal imaging approach when appropriate. Here, we emphasize the val...

A new blood filtration technology may prove to be life-saving for patients whose normally healthy inflammatory response to injury or illness has gone into overdrive, resulting in fatally high levels of cytokines in their blood. In an interview with MD+DI, Dr. Phillip Chan, MD, PhD, CEO of CytoSorbents Corp., explained that inflammation, and the production of substances called cytokines that drive inflammation, are the body’s natural response to heal injury or infection. But sometimes, the inflammatory response is so severe in such conditions as sepsis and infection, burn injuries, trauma, pancreatitis, li...

Genome studies of heart valve tissue (HVT) in patients with structural valvular heart disease (sVHD) and acute infective endocarditis (aIE) showed polymicrobial infections. Subject of this study is the quantification of bacterial DNA in HVT of sVHD in comparison to aIE. It will be examined whether the bacterial DNA concentration can be used as surrogate marker to differentiate chronic and acute infections. DNA was isolated from HVT of 100 patients with sVHD and 23 microbiologically positively tested patients with aIE.

AbstractCorynebacterium is a genus that can contaminate blood cultures and also cause severe infections like infective endocarditis (IE). Our purpose was to investigate microbiological and clinical features associated with contamination and true infection. A retrospective population-based study ofCorynebacterium bacteremia 2012 –2017 in southern Sweden was performed.Corynebacterium isolates were species determined using a matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS). Patient were, from the medical records, classified as having true infection or contamination caused byCor...

The aim of this study was to evaluate the application of transthoracic echocardiography for the diagnosis of infective endocarditis (IE) to provide a basis for the better treatment of IE. From October 2016 to October 2018, 87 consecutive patients with IE at our hospital were selected for this study. All the patients were subjected to transthoracic echocardiography. The morphology, structure, activity, and closure of the patients’ heart valves were observed for vegetation identification, and the size, number, location, morphology, and echo intensity of vegetation, as well as degree of valve involvement, were determine...

In this study, C.burnetii was isolated by cell culture method from the heart valve tissue of a Q fever endocarditis case. C.burnetii phase I antigen for the indirect fluorescent antibody test (IFAT) was prepared from the isolated strain. For the isolation and identification of C.burnetii, heart valve tissue of the patient was homogenized and DNA was extracted by tissue extraction kit. C.burnetii DNA in the valve tissue was determined by real-time PCR (Rt-PCR). This C.burnetii DNA positive specimen was inoculated into Vero cells by shell vial centrifugation method. The scraped Vero cells were fixed on the slides after one w...

;re D Abstract The combination of aortic and mitral regurgitation is a typical example of a frequent yet understudied multiple valve disease scenario. The aetiology is often rheumatic or degenerative; less frequently it can be induced by drugs or radiation, or caused by infective endocarditis or congenital valvular lesions. Aortic regurgitation resulting in secondary mitral regurgitation is also not uncommon. There are limited data to guide the management of combined aortic and mitral regurgitation. Left ventricular dysfunction is frequent at initial presentation, and even more so postoperatively, suggesting that ...

Abstract Right-sided infective endocarditis (IE) represents 5-10% of IE. It may occur in patients with electronic intracardiac device, central venous catheter or congenital heart disease, but the most frequent situation is intravenous drug use. Prosthetic valve IE is the most severe form of IE. The diagnosis is more challenging than that of native valve IE, as is treatment, both antibiotic treatment and surgical indications. The infection of an electronic intracardiac device is a severe disease. Both diagnostic and therapeutic strategies are difficult. PMID: 31109767 [PubMed - as supplied by publisher]

Abstract The annual incidence of infective endocarditis is estimated around 30 cases per million inhabitants in population-based studies performed in western countries. The incidence of infective endocarditis is markedly increased in patients with prosthetic heart valves and, particularly, in patients with prior infective endocarditis. The epidemiology of infective endocarditis has changed ; it occurs now in older patients and Staphylococcus has become the most frequent responsible microorganism. The pathophysiology of infective endocarditis results of complex interactions between circulating microorganisms, ...
