Mural Endocarditis: The GAMES Registry Series and Review of the Literature

Introduction: Mural infective endocarditis (MIE) is a rare type of endovascular infection. We present a comprehensive series of patients with mural endocarditis. Methods: Patients with infectious endocarditis (IE) from 35 Spanish hospitals were prospectively included in the GAMES registry between 2008 and 2017. MIEs were compared to non-MIEs. We also performed a literature search for cases of MIE published between 1979 and 2019 and compared them to the GAMEs series. Results: Twenty-seven MIEs out of 3676 IEs were included. When compared to valvular IE (VIE) or device-associated IE (DIE), patients with MIE were younger (median age 59 years, p < 0.01). Transplantation (18.5% versus 1.6% VIE and 2% DIE, p < 0.01), hemodialysis (18.5% versus 4.3% VIE and 4.4% DIE, p = 0.006), catheter source (59.3% versus 9.7% VIE and 8.8% DIE, p < 0.01) and Candida etiology (22.2% versus 2% DIE and 1.2% VIE, p < 0.01) were more common in MIE, whereas the Charlson Index was lower (4 versus 5 in non-MIE, p = 0.006). Mortality was similar. MIE from the literature shared many characteristics with MIE from GAMES, although patients were younger (45 years vs. 56 years, p < 0.001), the Charlson Index was lower (1.3 vs. 4.3, p = 0.0001), catheter source was less common (13.9% vs. 59.3%) and there were more IVDUs (25% vs. 3.7%). S. aureus was the most frequent microorganism (50%, p = 0.035). Systemic complications were more common but mortality was similar. Conclusion: MIE is a rare entity. It is often a complication of catheter use, particularly in immunocompromised and hemodialysis patients. Fungal etiology is common. Mortality is similar to other IEs

Effect of the type of surgical indication on mortality in patients with infective endocarditis who are rejected for surgical intervention

AIM: To evaluate the effect of the type of surgical indication on mortality in infective endocarditis (IE) patients who are rejected for surgery. METHODS AND RESULTS: From January 2008 to December 2016, 2714 patients with definite left-sided IE were attended in the participating hospitals. One thousand six hundred and fifty-three patients (60.9%) presented surgical indications. Five hundred and thirty-eight patients (32.5%) presented surgical indications but received medical treatment alone. The indications for surgery in these patients were uncontrolled infection (366 patients, 68%), heart failure (168 patients, 31.3%) and prevention of embolism (148 patients, 27.6%). One hundred and thirty patients (24.2%) presented more than one indication. The mortality during hospital admission was 60% (323 patients). The in-hospital mortality of patients whose indication for surgery was heart failure, uncontrolled infection or risk of embolism was 75.6%, 61.4% and 54.7%, respectively (p?<?0.001). Surgical indications due to heart failure (OR: 3.24; CI 95%: 1.99-5.9) or uncontrolled infection (OR: 1.83; CI 95%: 1.04-3.18) were independently associated with a fatal outcome during hospital admission. Mortality during the first year was 75.4%. The mortality during the first year in patients whose indication for surgery was heart failure, uncontrolled infection or risk of embolism was 85.9%, 76.7% and 72.7%, respectively (p?=?0.016). Surgical indication due to heart failure (OR: 3.03; CI 95%: 1.53-5.98) were independently associated with fatal outcome during the first year. CONCLUSIONS: The type of surgical indication is associated with mortality in IE patients who are rejected for surgical intervention

Detection of spleen, kidney and liver infarcts by abdominal computed tomography does not affect the outcome in patients with left-side infective endocarditis.

Extra-cardiac abdominal complications are common in left-side infective endocarditis (LS-IE). The aim of this work was to study whether patients with LS-IE presenting splenic, renal, or liver (SRL) involvement seen in abdominal computed tomography (CT) had different clinical features, therapeutic plans, and outcome than those without these findings on CT.From January 2008 to April 2010, multidisciplinary teams have prospectively collected all consecutive cases of IE, diagnosed according to the Duke criteria, in which abdominal CT was performed.A total of 147 patients with LS-IE had abdominal CT. Fifty (34%) had SRL lesions: 46 splenic, 15 renal, 1 liver infarct, and 2 liver abscesses. Patients with SRL lesions were mainly men (P = .01), had liver disease (P = .001) with natural valve (P = .050) and mitro-aortic valve involvement (P = .042), splenomegaly (P = .001), nonabdominal emboli (P = .001), and a greater number and larger vegetation (>15 mm, P = .049) in the mitro-aortic valves (P = .051) than patients with normal abdominal CT. The site of acquisition, clinical characteristics, microbiology, surgical treatment, days of hospitalization, hospital death, and 1-year mortality were similar in patients with and without SRL emboli on CT. In the stepwise logistic regression analysis, male gender (odds ratio [OR] = 3.6, 95% confidence interval [CI] = 1.4-9.1), liver disease (OR = 8.3, 95% CI = 2.1-31.8), and nonabdominal emboli (OR = 5.2, 95% CI = 2.3-11.7) were independently associated with SRL lesions.Male patients with native LS-IE who had liver disease and nonabdominal emboli had more frequent abdominal lesions seen on CT. The presence of SRL infarcts on abdominal CT scan performed on patients with LS-IE seems to have poor practical implications, and as a consequence, its realization should only be considered when there are symptoms or signs that suggest them

Characteristics and Outcome of Acute Heart Failure in Infective Endocarditis: Focus on Cardiogenic Shock

Background: Studies investigating the impact of cardiogenic shock (CS) on endocarditis are lacking. Methods: Prospectively collected cohort from 35 Spanish centers (2008-2018). Logistic regression analyses were performed to identify risk factors for developing CS and predictors of mortality. Results: Among 4856 endocarditis patients, 1652 (34%) had acute heart failure (AHF) and 244 (5%) CS. Compared with patients without AHF and AHF but no CS, patients with CS presented higher rates of surgery (40.5%, 52.5%, and 68%; P < .001) and in-hospital mortality (16.3%, 39.1%, and 52.5%). Compared with patients with septic shock, CS patients presented higher rates of surgery (42.5% vs 68%; P < .001) and lower rates of in-hospital and 1-year mortality (62.3% vs 52.5%, P = .008, and 65.3% vs 57.4%, P = .030). Severe aortic and mitral regurgitation (OR [95% CI], 2.47 [1.82-3.35] and 3.03 [2.26-4.07]; both P < .001), left-ventricle ejection fraction <60% (1.72; 1.22-2.40; P = .002), heart block (2.22; 1.41-3.47; P = .001), tachyarrhythmias (5.07; 3.13-8.19; P < .001), and acute kidney failure (2.29; 1.73-3.03; P < .001) were associated with higher likelihood of developing CS. Prosthetic endocarditis (2.03; 1.06 -3.88; P = .032), Staphylococcus aureus (3.10; 1.16 -8.30; P = .024), tachyarrhythmias (3.09; 1.50-10.13; P = .005), and not performing cardiac surgery (11.40; 4.83-26.90; P < .001) were associated with a higher risk of mortality. Conclusions: AHF is common among patients with endocarditis. CS is associated with high mortality and should be promptly identified and assessed for cardiac surgery.Sin financiación20.999 JCR (2021) Q1, 7/161 Immunology4.394 SJR (2021) Q1, 8/301 Infectious DiseasesNo data IDR 2020UE

Comorbidity and Prognosis in Octogenarians with Infective Endocarditis

Background: Infective endocarditis (IE) in older patients is associated with a high morbidity, mortality, and functional impairment. The purpose of this study was to describe the current profile of IE in octogenarians and to analyze the prognostic impact of baseline comorbidities in this population. Methods: Patients ? 80 years and definite IE from the Spanish IE Prospective Database were included. The effect of Charlson Comorbidity Index (CCI) on in-hospital and 12-month mortality was analyzed. Results: From 726 patients, 357 (49%) had CCI ? 3 and 369 (51%) CCI &lt; 3. A total of 265 patients (36.6%) died during hospital admission and 338 (45.5%) during 1-year follow-up. CCI ? 3 was an independent predictor of in-hospital and 1-year mortality (odds ratio 1.46, 95% confidence interval 1.07-1.99, p = 0.017; hazard ratio 1.34, 95% confidence interval 1.08-1.66, p = 0.007, respectively). Surgical management was less common in patients with high comorbidity (CCI ? 3 68 [19.0%] vs. CCI &lt; 3 112 ((30.4%) patients, p &lt; 0.01). From 443 patients with surgical indication, surgery was only performed in 176 (39.7%). Patients with surgical indication treated conservatively had higher mortality than those treated with surgery (in-hospital mortality: 147 (55.1%) vs. 55 (31.3%), p &lt; 0.001), (1-year mortality: 172 (64.4%) vs. 68 [38.6%], p &lt; 0.001). Conclusion: About half of octogenarians with IE had high comorbidity with CCI ? 3. CCI ? 3 was a strong independent predictor of in-hospital and 1-year mortality. Our data suggest that the underperformance of cardiac surgery in this group of patients might have a role in their poor prognosis.OsteoporosisOsteoporotic fracturesAnti-osteoporotic treatmentComorbiditiesLogistic regressionArtificial neural networ

Linezolid for infective endocarditis: A structured approach based on a national database experience

Current data on the frequency and efficacy of linezolid (LNZ) in infective endocarditis (IE) are based on small retrospective series. We used a national database to evaluate the effectiveness of LNZ in IE.This is a retrospective study of IE patients in the Spanish GAMES database who received LNZ. We defined 3 levels of therapeutic impact: LNZ 50% of the total treatment, and > 50% of the LNZ doses prescribed in the first weeks of treatment), and LNZ ≥ 7 days not fulfilling the high-impact criteria (LNZ-NHI). Effectiveness of LNZ was assessed using propensity score matching and multivariate analysis of high-impact cases in comparison to patients not treated with LNZ from the GAMES database matched for age-adjusted comorbidity Charlson index, heart failure, renal failure, prosthetic and intracardiac IE device, left-sided IE, and Staphylococcus aureus. Primary outcomes were in-hospital mortality and one-year mortality. Secondary outcomes included IE complications and relapses.From 3467 patients included in the GAMES database, 295 (8.5%) received LNZ. After excluding 3 patients, 292 were grouped as follows for the analyses: 99 (33.9%) patients in LNZ < 7 days, 11 (3.7%) in LNZ high-impact, and 178 (61%) in LNZ-NHI. In-hospital mortality was 51.5%, 54.4%, and 19.1% respectively. In the propensity analysis, LNZ high-impact group presented with respect to matched controls not treated with LNZ higher in-hospital mortality (54.5% vs 18.2%, P = .04). The multivariate analysis showed an independent relationship of LNZ use with in-hospital mortality (odds ratio 9.06, 95% confidence interval 1.15--71.08, P = .03).Treatment with LNZ is relatively frequent, but most cases do not fulfill our high-impact criteria. Our data suggest that the use of LNZ as definitive treatment in IE may be associated with higher in-hospital mortality.Sin financiación1.817 JCR (2021) Q3, 122/172 Medicine, General & Internal0.470 SJR (2021) Q3, 1294/2489 Medicine (miscellaneous)No data IDR 2020UE

Infective Endocarditis in Patients With Bicuspid Aortic Valve or Mitral Valve Prolapse.

There is little information concerning infective endocarditis (IE) in patients with bicuspid aortic valve (BAV) or mitral valve prolapse (MVP). Currently, IE antibiotic prophylaxis (IEAP) is not recommended for these conditions. This study sought to describe the clinical and microbiological features of IE in patients with BAV and MVP and compare them with those of IE patients with and without IEAP indication, to determine the potential benefit of IEAP in these conditions. This analysis involved 3,208 consecutive IE patients prospectively included in the GAMES (Grupo de Apoyo al Manejo de la Endocarditis infecciosa en España) registry at 31 Spanish hospitals. Patients were classified as high-risk IE with IEAP indication (high-risk group; n = 1,226), low- and moderate-risk IE without IEAP indication (low/moderate-risk group; n = 1,839), and IE with BAV (n = 54) or MVP (n = 89). BAV and MVP patients had a higher incidence of viridans group streptococci IE than did high-risk group and low/moderate-risk group patients (35.2% and 39.3% vs. 12.1% and 15.0%, respectively; all p  IE in patients with BAV and MVP have higher rates of viridans group streptococci IE and IE from suspected odontologic origin than in other IE patients, with a clinical profile similar to that of high-risk IE patients. Our findings suggest that BAV and MVP should be classified as high-risk IE conditions and the case for IEAP should be reconsidered

Epidemiology and risk factors of mycotic aneurysm in patients with infective endocarditis and the impact of its rupture in outcomes. Analysis of a national prospective cohort

Background. Several aspects of the occurrence and management of mycotic aneurysm (MA) in patients with infective endocarditis (IE) have not been studied. Objectives. To determine the incidence and factors associated with MA presence and rupture and to assess the evolution of those initially unruptured MA. Methods. Prospective multicenter cohort including all patients with definite IE between January 2008 and December 2020. Results. Of 4548 IE cases, 85 (1.9%) developed MA. Forty-six (54.1%) had intracranial MA and 39 (45.9%) extracranial MA. Rupture of MA occurred in 39 patients (45.9%). Patients with ruptured MA had higher 1-year mortality (hazard ratio, 2.33; 95% confidence interval, 1.49–3.67). Of the 55 patients with initially unruptured MA, 9 (16.4%) presented rupture after a median of 3 days (interquartile range, 1–7) after diagnosis, being more frequent in intracranial MA (32% vs 3.3%, P = .004). Of patients with initially unruptured MA, there was a trend toward better outcomes among those who received early specific intervention, including lower follow-up rupture (7.1% vs 25.0%, P = .170), higher rate of aneurysm resolution in control imaging (66.7% vs 31.3%, P = .087), lower MA-related mortality (7.1% vs 16.7%, P = .232), and lower MA-related sequalae (0% vs 27.8%, P = .045). Conclusions. MA occurred in 2% of the patients with IE. Half of the Mas occurred in an intracranial location. Their rupture is frequent and associated with poor prognosis. A significant proportion of initially unruptured aneurysms result from rupture during the first several days, being more common in intracranial aneurysms. Early specific treatment could potentially lead to better outcome

Role of age and comorbidities in mortality of patients with infective endocarditis.

The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups: A total of 3120 patients with IE (1327  There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in th
