Abstract Introduction Infective endocarditis (IE) is associated with a high in-hospital and long term mortality. Although progress has been made in diagnostic approach and management of IE, morbidity and mortality of IE remain high. In the latest European guidelines, the importance of the multi-modality imaging in diagnosis and follow up of IE is emphasized. Aim The aim was to provide information regarding mortality and adverse events of IE, to determine IE characteristics and to assess current use of imaging in the diagnostic workup of IE. Methods This is a prospective observational cohort study. We used data from the EURO-ENDO registry. Seven hospitals in the Netherlands have participated and included patients with IE between April 2016 and April 2018. Results A total of 139 IE patients were included. Prosthetic valve endocarditis constituted 32.4% of the cases, cardiac device related IE 7.2% and aortic root prosthesis IE 3.6%. In-hospital mortality was 14.4% (20 patients) and one-year mortality was 21.6% (30 patients). The incidence of embolic events under treatment was 16.5%, while congestive heart failure or cardiogenic shock occurred in 15.1% of the patients. Transthoracic and transoesophageal echocardiography were performed most frequently (97.8%; 81.3%) and within 3 days after IE suspicion, followed by 18F‑fluorodeoxyglucose positron emission tomography/computed tomography (45.3%) within 6 days and multi-slice computed tomography (42.4%) within 7 days. Conclusion We observed a high percentage of prosthetic valve endocarditis, rapid and extensive use of imaging and a relatively low in-hospital and one-year mortality of IE in the Netherlands. Limitations include possible selection bias.

Prosthetic valve endocarditis (PVE) complicates the clinical course of 1–6% of patients with prosthetic valves and it is one of the types of infective endocarditis with the worst prognosis. In early-onset PVE (that occurs within the first year after surgery), the microbiological profile is dominated by staphylococci. In late-onset PVE, the microorganisms are similar to native valve endocarditis. Clinical manifestations are very variable and depend on the causative microorganism. The diagnosis is established with the modified Duke criteria although they yield lower diagnostic accuracy than in native valve endocarditis. Transoesophageal echocardiography is the main imaging technique in everyday clinical practice in PVE as the sensitivity is higher than transthoracic echocardiography. The findings of other techniques, as cardiac computed tomography (CT), positron emission tomography/CT, or single-photon emission computed tomography/CT have been recently recognized as new major diagnostic criteria and can be very useful in cases with a high level of clinical suspicion and negative echocardiography. Empirical antibiotic treatment should cover the most frequent microorganisms, especially staphylococci. Once the microbiological diagnosis is made, the antibiotic treatment is similar to native valve infective endocarditis, except for the addition of rifampicin in staphylococcal PVE and a longer length (up to 6 weeks) of the treatment. Surgical indications are also similar to native valve endocarditis, heart failure being the most common and embolic prevention the most debatable. Prognosis is bad, and during the follow-up, a team experienced with endocarditis is needed. Patients with a history of PVE should receive antibiotic prophylaxis if they undergo invasive dental manipulations.

Infective endocarditis is a heterogeneous condition whose incidence is rising. Despite advances in surgery and diagnostic methods, one-year mortality has not changed and it remains at 30%. Patients with prosthetic valve and intra-cardiac device–related endocarditis are being seen more frequently and this condition is difficult to diagnose with conventional microbiological and imaging techniques. The modified Duke criteria lack sensitivity in this group and should be supplemented with newer imaging techniques, including 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) and single-photon emission computed tomography (SPECT). In this article, we discuss these techniques and their role in the diagnosis of infective endocarditis.

Infective endocarditis is a common and treatable condition that carries a high mortality rate. Currently the workup of infective endocarditis relies on the integration of clinical, microbiological and echocardiographic data through the use of the modified Duke criteria (MDC). However, in cases of prosthetic valve endocarditis (PVE) echocardiography can be normal or non-diagnostic in a high proportion of cases leading to decreased sensitivity for the MDC. Evolving multimodality imaging techniques including leukocyte scintigraphy (white blood cell imaging), 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), multidetector computed tomographic angiography (MDCTA), and cardiac magnetic resonance imaging (CMRI) may each augment the standard workup of PVE and increase diagnostic accuracy. While further studies are necessary to clarify the ideal role for each of these imaging techniques, nevertheless, these modalities hold promise in determining the diagnosis, prognosis, and care of PVE. We start by presenting a clinical vignette, then evidence supporting various modality strategies, balanced by limitations, and review of formal guidelines, when available. The article ends with the authors' summary of future directions and case conclusion.
