Aims The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). Methods and results Prospective cohort of 3116 adult patients (2470 from Europe, 646 from non-ESC countries), admitted to 156 hospitals in 40 countries between January 2016 and March 2018 with a diagnosis of IE based on ESC 2015 diagnostic criteria. Clinical, biological, microbiological, and imaging [echocardiography, computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)] data were collected. Infective endocarditis was native (NVE) in 1764 (56.6%) patients, prosthetic (PVIE) in 939 (30.1%), and device-related (CDRIE) in 308 (9.9%). Infective endocarditis was community-acquired in 2046 (65.66%) patients. Microorganisms involved were staphylococci in 1085 (44.1%) patients, oral streptococci in 304 (12.3%), enterococci in 390 (15.8%), and Streptococcus gallolyticus in 162 (6.6%). 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in 518 (16.6%) patients and presented with cardiac uptake (major criterion) in 222 (42.9%) patients, with a better sensitivity in PVIE (66.8%) than in NVE (28.0%) and CDRIE (16.3%). Embolic events occurred in 20.6% of patients, and were significantly associated with tricuspid or pulmonary IE, presence of a vegetation and Staphylococcus aureus IE. According to ESC guidelines, cardiac surgery was indicated in 2160 (69.3%) patients, but finally performed in only 1596 (73.9%) of them. In-hospital death occurred in 532 (17.1%) patients and was more frequent in PVIE. Independent predictors of mortality were Charlson index, creatinine > 2 mg/dL, congestive heart failure, vegetation length > 10 mm, cerebral complications, abscess, and failure to undertake surgery when indicated. Conclusion Infective endocarditis is still a life-threatening disease with frequent lethal outcome despite profound changes in its clinical, microbiological, imaging, and therapeutic profiles.

1. Orbital accumulation of hydrophilic, interstitial glycosaminoglycans (GAGs) and subsequent expansion of retrobulbar tissue lead to the clinical manifestation of exophthalmos in patients with Graves' eye disease. 2. A highly specific method to determine the concentration and biochemical composition of different GAGs was developed in order to obtain a sensitive test system for the activity of the disease. By means of this method, GAG excretion in 24 h urine collections of 56 patients and 21 controls was analysed by precipitation with cetylpyridinium chloride and potassium acetate in ethanol, followed by sequential enzymic hydrolysis with chondroitin AC lyase, chondroitin ABC lyase and hyaluronate lyase, with HPLC analysis of the resulting alpha, beta-unsaturated disaccharides by anion-exchange chromatography. 3. Concentrations of GAG, chondroitin sulphate A (CA), dermatan sulphate (DS) and hyaluronic acid (HA) were determined in patients and controls, with high recovery rates [72.2 +/- 5.3%, mean +/- SEM; detection limit, 4.2 micrograms/l (0.01 mumol/l)], revealing marked differences in urinary concentrations of total GAG and HA, as well as an elevation of CA in patients compared with controls. 4. Method sensitivity was 0.86 for patients with active Graves' eye disease, and 0.87 for patients with untreated ophthalmopathy, whereas specificity was 1.0 for patients with inactive disease. Patients with increased GAG concentration responded well to steroids and/or orbital irradiation (before therapy: GAG, 111.49 +/- 40.32; CA, 59.58 +/- 21.34; DS, 25.05 +/- 8.12; HA, 26.88 +/- 11.63 mg/24 h; during therapy: GAG, 54.22 +/- 10.94; CA, 20.52 +/- 4.58; DS, 17.65 +/- 3.46; HA, 16.05 +/- 3.69 mg/24 h), whereas GAG excretion increased markedly 2-3 months after stopping prednisone therapy in patients with still active eye disease (GAG, 109.9 +/- 10.51; CA, 63.8 +/- 7.34; DS, 24.1 +/- 5.07; HA, 22.0 +/- 6.28 mg/24 h). 5. This sensitive method determines the nature of renally excreted GAGs, reflecting the aberrant synthesis pattern of fibroblasts in patients with Graves' disease.

Purpose High mortality and a limited performance of valvular surgery are typical features of infective endocarditis (IE) in octogenarians, even though surgical treatment is a major determinant of a successful outcome in IE. Methods Data from the prospective multicentre ESC EORP EURO-ENDO registry were used to assess the prognostic role of valvular surgery depending on age. Results As compared to < 80 yo patients, ≥ 80 yo had lower rates of theoretical indication for valvular surgery (49.1% vs. 60.3%, p < 0.001), of surgery performed (37.0% vs. 75.5%, p < 0.001), and a higher in-hospital (25.9% vs. 15.8%, p < 0.001) and 1-year mortality (41.3% vs. 22.2%, p < 0.001). By multivariable analysis, age per se was not predictive of 1-year mortality, but lack of surgical procedures when indicated was strongly predictive ). By propensity analysis, 304 ≥ 80 yo were matched to 608 < 80 yo patients. Propensity analysis confirmed the lower rate of indication for valvular surgery (51.3% vs. 57.2%, p = 0.031) and of surgery performed (35.3% vs. 68.4%, p < 0.0001) in ≥ 80 yo. Overall mortality remained higher in ≥ 80 yo (in-hospital: HR 1.50[1.06-2.13], p = 0.0210; 1-yr: HR 1.58[1.21-2.05], p = 0.0006), but was not different from that of < 80 yo among those who had surgery (in-hospital: 19.7% vs. 20.0%, p = 0.4236; 1-year: 27.3% vs. 25.5%, p = 0.7176). Conclusion Although mortality rates are consistently higher in ≥ 80 yo patients than in < 80 yo patients in the general population, mortality of surgery in ≥ 80 yo is similar to < 80 yo after matching patients. These results confirm the importance of a better recognition of surgical indication and of an increased performance of surgery in ≥ 80 yo patients.

In this single-center series interventional PVL closure appears promising for patients at high surgical risk with symptomatic paravalvular regurgitation. Gaining experience in interventional PVL closure at specialized sites will further improve safety and efficacy of this relatively new treatment option. All patients should be treated within large clinical registries to gain more data on mid- and long-term efficacy of transcatheter PVL closure.

Objective Infective endocarditis (IE) is still a serious disease. The currently published EURO-ENDO registry showed a rate of surgery of 51.2% and a lower mortality in operated IE patients. We hypothesized differences between our data and the registry. Methods Retrospective single centre registry on the hospital course of patients with IE. Results In four years, 171 IE patients were treated at our hospital. Mean age of patients was 66.5 ± 13.8 years and 62.6% of patients were transferred from other hospitals. There were 85 (49.7%) patients with native valve IE (NVE), 53 (31%) with prosthetic valve IE (PVE) and 33 (19.3%) with either intra-cardiac device related IE (n = 29) or IE associated with central access lines (n = 4) (DRE). A total of 81.3% (n = 139) of patients were sent to cardiac surgery. Using a logistic regression model to analyse predictors of conservative instead of surgical therapy the only independent variables were: presence of large vegetation or abscesses (OR: 0.36, 95%CI 0.15–0.83; p = 0.016) and age (for each ten years) (OR: 1.61, 95%CI 1.11–2.32, p = 0.01). Hospital mortality was 21.6% (n = 37/171), with no difference (p = 0.97) between those who were operated (21.6%, n = 30/139) and those treated conservatively (21.9%, n = 7/32). Comparing those treated conservatively without an indication for surgery with those with an indication, mortality was 9.5% versus 45.5%, p = 0.02. Conclusions In this registry from a hospital with on-site cardiac surgery more than half of patients were referred. The rate of patients treated surgically was 81.3%. Hospital mortality was 21.6%, with no difference between operated and conservatively treated patients.
