Clinical profile and one-year outcomes of patients with mural infective endocarditis: - A tertiary care centre study based on data from a seven-year registry.

ABSTRACT:

Background

Infective endocarditis patients present very rarely with vegetations on the mural endocardium. Only very few studies are available comparing Mural infective endocarditis with commoner valvular or device related infective endocarditis.

Aim

To analyse the clinical features, microbiological profile and clinical course of mural endocarditis in comparison to valvular endocarditis.

Methods

This was a retrospective analysis of data from a registry of infective endocarditis. Patients enrolled between April 2012 and April 2019 were included. Patients who were reported to have vegetations on the mural endocardial surface were taken as a group and compared with rest of the patients. Clinical profile, laboratory parameters including culture and outcomes were compared between the two groups.

Results

Out of 278 patients in the study, 15 (5.38%) had vegetations on the mural endocardium. Of them, only 4 patients had structural heart diseases. All the patients with mural endocarditis were NYHA class II or below at presentation. Ventricles were the commonest sites of vegetations. Inflammatory markers like ESR and CRP were low in mural endocarditis compared to rest. Culture positivity was high in mural endocarditis and Staphylococcus Aureus was the commonest organism. Mural endocarditis patients had similar in hospital mortality to rest of the patients. Cardiac complications were not reported in mural endocarditis, but they had similar incidence of embolic complications including neurological events.

Conclusion

Mural endocarditis is a rare clinical entity with similar morbidity and mortality to that of endocarditis with valvular vegetation.

Right ventricular mural infective endocarditis after traumatic tricuspid valve regurgitation in a 40-year-old man: A case report

Project description:As the clinical manifestations of traumatic tricuspid valve regurgitation vary according to the extent of tricuspid valve injury, this condition can often go unnoticed and be incidentally discovered. Here, we report the case of a 40-year-old man with patent foramen ovale, in which severe tricuspid regurgitation due to tricuspid valve prolapse was incidentally discovered following blunt chest trauma. Further examination revealed that the prolapse had also caused active right ventricular mural infective endocarditis. The patient had no relevant past medical history of chronic debilitating disease or immunosuppression. After evaluation by the cardiology team, emergent surgical tricuspid valvular repair was successfully performed. Learning objective Tricuspid valve prolapses resulting from chest trauma may occasionally lead to severe tricuspid regurgitation. Furthermore, this may cause active right ventricular infective endocarditis. In the present case, Staphylococcus aureus was detected in blood cultures, which is usually rapidly progressive and often leads to devastating consequences. Early surgical approach should be considered in cases of infection in the left atrium via patent foramen ovale.

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

Project description:IntroductionMural infective endocarditis (MIE) is a rare type of endovascular infection. We present a comprehensive series of patients with mural endocarditis.MethodsPatients 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.ResultsTwenty-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.ConclusionMIE 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.

Microbiological and clinical profile of infective endocarditis patients: an observational study experience from tertiary care center Karachi Pakistan.

Project description:BackgroundThe study analyzed microbiological and antimicrobial susceptibility profile of organisms isolated from patients with infective endocarditis (2015-17) and compared disease outcomes in cohorts of endocarditis patient with history of prior invasive vascular intervention (high risk group) vs those without (native valve group). We hypothesized that high risk group would be more likely to have severe disease outcomes.MethodsThis was a prospective cohort study (2015-17). All blood and cardiac tissue samples of enrolled patients suspected of endocarditis according to modified Duke's criteria were followed for microbiological and antimicrobial susceptibility profile. The high risk group was compared with the native valve group with 90 day follow up to determine difference in clinical course and outcome in terms of disease severity (defined as any patient with endocarditis undergoing surgical management, readmission or dying). The data was analyzed using SPSS 21.0 software and chi-square test. 90 day mortality was calculated using Kaplan Meier survival curves.ResultsTotal 104 patients with endocarditis were enrolled. Overall culture positivity rate was 71.2%. Streptococcus species were the most common isolate (36.7%), followed by S. aureus (17.3%) cases. In Streptococcus species, 14.2% showed intermediate susceptibility to penicillin. Thirty six patients were included in the cohort analysis. A poor outcome was seen in 85.7% high risk group as compared to 50% of native valve group. The overall mortality rate was 19.4%.ConclusionsWe found Streptococcus species to be the predominant pathogen for endocarditis overall. However Staphylococcus aureus predominated native valve group. High risk group showed more complicated clinical course.

Seven Year Old Male with Tricuspid Endocarditis.

Project description:Pediatric endocarditis, a rare entity in developed countries, remains a challenging diagnosis to make in children. We present an uncommon etiology of shortness of breath on exertion (SOBOE) in a 7-year-old male presenting with two weeks of nocturnal fever, malaise and fatigue following a viral prodrome. Point of care ultrasound (POCUS) led to suspicion for a ventricular septal defect (VSD) with tricuspid valve (TV) endocarditis, which was ultimately confirmed by formal echocardiography. This ultrasound diagnosis allowed emergency clinicians to order blood cultures under the suspicion of endocarditis as well as expedited antibiotic treatment.

Clinical features and outcomes of infective endocarditis in Egypt: an 11-year experience at a tertiary care facility.

Project description:BackgroundFew data are available on the characteristics of infective endocarditis (IE) cases in Egypt. The aim of this work is to describe the characteristics and outcomes of IE patients and evaluate the temporal changes in IE diagnostic and therapeutic aspects over 11 years.ResultsThe IE registry included 398 patients referred to the Endocarditis Unit of a tertiary care facility with the diagnosis of possible or definite IE. Patients were recruited over two periods; period 1 (n = 237, 59.5%) from February 2005 to December 2011 and period 2 (n = 161, 40.5%) from January 2012 to September 2016. An electronic database was constructed to include information on patients' clinical and microbiological characteristics as well as complications and mortality. The median age was 30 years and rheumatic valvular heart disease was the commonest underlying cardiac disease (34.7%). Healthcare-associated IE affected 185 patients (46.5%) and 275 patients (69.1%) had negative blood cultures. The most common complications were heart failure (n = 148, 37.2%), peripheral embolization (n = 133, 33.4%), and severe sepsis (n = 100, 25.1%). In-hospital mortality occurred in 108 patients (27.1%). Period 2 was characterized by a higher prevalence of injection drug use-associated IE (15.5% vs. 7.2%, p = 0.008), a higher staphylococcal IE (50.0% vs. 35.7%, p = 0.038), lower complications (31.1% vs. 45.1%, p = 0.005), and a lower in-hospital mortality (19.9% vs. 32.1%, p = 0.007).ConclusionThis Egyptian registry showed high rates of culture-negative IE, complications, and in-hospital mortality in a largely young population of patients. Improvements were noted in the rates of complications and mortality in the second half of the reporting period.

Microbiological profile and risk factors for in-hospital mortality of infective endocarditis in tertiary care hospitals of south Vietnam.

Project description:ObjectivesWe aimed to evaluate the microbiological characteristics and risk factors for mortality of infective endocarditis in two tertiary hospitals in Ho Chi Minh City, south Vietnam.Materials and methodsA retrospective study of 189 patients (120 men, 69 women; mean age 38 ± 18 years) with the diagnosis of probable or definite infective endocarditis (IE) according to the modified Duke Criteria admitted to The Heart Institute or Tam Duc Hospital between January 2005 and December 2014.ResultsIE was related to a native valve in 165 patients (87.3%), and prosthetic valve in 24 (12.7%). Of the 189 patients in our series, the culture positive rate was 70.4%. The most common isolated pathogens were Streptococci (75.2%), Staphylococci (9.8%) followed by gram negative organism (4.5%). The sensitivity rate of Streptococci to ampicillin, ceftriaxone or vancomycin was 100%. The rate of methicillin resistant Staphylococcus aureus was 40%. There was a decrease in penicillin sensitivity for Streptococci over three eras: 2005-2007 (100%), 2008-2010 (94%) and 2010-2014 (84%). The in-hospital mortality rate was 6.9%. Logistic regression analysis found prosthetic valve and NYHA grade 3 or 4 heart failure and vegetation size of more than 15 mm as strong predictors of in-hospital mortality.ConclusionStreptococcal species were the major pathogen of IE in the recent years with low rates of antimicrobial resistance. Prosthetic valve involvement, moderate or severe heart failure and vegetation size of more than 15 mm were independent predictors for in-hospital mortality in IE.

Forty-Year Trends in Cardiac Implantable Electronic Device Infective Endocarditis.

Project description:BackgroundStudies investigating cardiac implantable electronic device infective endocarditis (CIED-IE) epidemiological changes and prognosis over long periods of time are lacking.MethodsRetrospective single cardiovascular surgery center cohort study of definite CIED-IE episodes between 1981-2020. A comparative analysis of two periods (1981-2000 vs 2001-2020) was conducted to analyze changes in epidemiology and outcome over time.ResultsOne-hundred and thirty-eight CIED-IE episodes were diagnosed: 25 (18%) first period and 113 (82%) second. CIED-IE was 4.5 times more frequent in the second period, especially in implantable cardiac defibrillators. Age (63 [53-70] vs 71 [63-76] years, P < .01), comorbidities (CCI 3.0 [2-4] vs 4.5 [3-6], P > .01), nosocomial infections (4% vs 15.9%, P = .02) and transfers from other centers (8% vs 41.6%, P < .01) were significantly more frequent in the second period, as were methicillin-resistant coagulase-negative staphylococcal (MR-CoNS) (0% vs 13.3%, P < .01) and Enterococcus spp. (0% vs 5.3%, P = .01) infections, pulmonary embolism (0% vs 10.6%, P < .01) and heart failure (12% vs 28.3%, p < .01). Second period surgery rates were lower (96% vs 87.6%, P = .09), and there were no differences in in-hospital (20% vs 11.5%, P = .11) and one-year mortalities (24% vs 15%, P = .33), or relapses (8% vs 5.3%, P = 0.65). Multivariate analysis showed Charlson index (hazard ratios [95% confidence intervals]; 1.5 [1.16-1.94]) and septic shock (23.09 [4.57-116.67]) were associated with a worse prognosis, whereas device removal (0.11 [.02-.57]), transfers (0.13 [.02-0.95]), and second-period diagnosis (0.13 [.02-.71]) were associated with better one-year outcomes.ConclusionsCIED-IE episodes increased more than four-fold during last 40 years. Despite CIED-IE involved an older population with more comorbidities, antibiotic-resistant MR-CoNS, and complex devices, one-year survival improved.

Infective endocarditis.

Project description:Infective endocarditis (IE) is a rare, life-threatening disease that has long-lasting effects even among patients who survive and are cured. IE disproportionately affects those with underlying structural heart disease and is increasingly associated with health care contact, particularly in patients who have intravascular prosthetic material. In the setting of bacteraemia with a pathogenic organism, an infected vegetation may form as the end result of complex interactions between invading microorganisms and the host immune system. Once established, IE can involve almost any organ system in the body. The diagnosis of IE may be difficult to establish and a strategy that combines clinical, microbiological and echocardiography results has been codified in the modified Duke criteria. In cases of blood culture-negative IE, the diagnosis may be especially challenging, and novel microbiological and imaging techniques have been developed to establish its presence. Once diagnosed, IE is best managed by a multidisciplinary team with expertise in infectious diseases, cardiology and cardiac surgery. Antibiotic prophylaxis for the prevention of IE remains controversial. Efforts to develop a vaccine that targets common bacterial causes of IE are ongoing, but have not yet yielded a commercially available product.
