The hidden side of infective endocarditis: Diagnostic and management of 500 consecutive cases in noncardiac surgery centers (2009-2018). Surgery 2023; 174:602-610.

Abstract
BACKGROUND We aimed to describe infective endocarditis cases from noncardiac surgery centers, as current knowledge on infective endocarditis is derived mostly from cardiac surgery hospitals. METHODS An observational retrospective study (2009-2018) was conducted in 9 noncardiac surgery hospitals in Central Catalonia. All adult patients diagnosed with definitive infective endocarditis were included. Transferred and nontransferred cohorts were compared, and a logistic regression model was used to ascertain the prognostic factors. RESULTS Overall, 502 infective endocarditis episodes were included: 183 (36.5%) were transferred to the cardiac surgery center, whereas 319 were not, with (18.7%) and without (45%) surgical indications. Cardiac surgery was performed in 83% of transferred patients. In-hospital (14% vs 23%) and 1-year (20% vs 35%) mortality rates were significantly lower in transferred patients (P < .001). Among the patients not undergoing cardiac surgery despite an indication, 55 (54%) died within 1 year. The multivariate analysis identified the following independent predictive factors for in-hospital mortality: Staphylococcus aureus infective endocarditis (odds ratio: 1.93 [1.08, 3.47]), heart failure (odds ratio: 3.87 [2.28, 6.57]), central nervous system embolism (odds ratio: 2.95 [1.41, 5.14]), and Charlson score (odds ratio: 1.19 [1.09, 1.30]), whereas community acquisition (odds ratio: 0.52 [0.29, 0.93]), cardiac surgery (odds ratio: 0.42 [0.20, 0.87]), but not transfer (odds ratio: 1.23 [0.84, 3.95]) were identified as protective factors. One-year mortality was associated with S. aureus infective endocarditis (odds ratio: 1.82 [1.04, 3.18]), heart failure (odds ratio: 3.74 [2.27, 6.16]), and Charlson score (odds ratio: 1.23 [1.13, 1.33]), whereas cardiac surgery (odds ratio: 0.41 [0.21, 0.79]) was identified as a protective factor. CONCLUSION Patients not transferred to a referral cardiac surgery center have a worse prognosis compared to those ultimately transferred, as cardiac surgery is associated with lower mortality rates.

Infective endocarditis and oral surgery input before cardiac surgery: time to prick the paradigm of pre-cardiac surgery assessments? Br Dent J 2023; 234:678-681. [PMID: 37173494 PMCID: PMC10177729 DOI: 10.1038/s41415-023-5796-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 12/22/2022] [Accepted: 01/17/2023] [Indexed: 05/15/2023]
Abstract
Purpose To review current practice regarding oral surgery input for patients awaiting cardiac valvular surgery and who are at risk of infective endocarditis (IE) in the context of the COVID-19 pandemic, and to stimulate debate around the indications for pre-operative oral surgery assessment. It also opens the way to developing a new research-based approach which is patient-centred, safe, effective and efficient.Methods A desk-top based patient review was undertaken between 27 March 2020 and 1 July 2022 to record the outcome of patients undergoing cardiac valvular surgery in Northern Ireland, following the revision of the referral guidelines for oral surgery intervention. Data were collected for all cardiac referrals to the oral surgery on-call service in the Royal Victoria Hospital, Belfast. Complications were recorded at two weeks, two months, and six months post-surgery, using Northern Ireland Electronic Care Records.Results In total, 67 cardiac patients were identified between 27 March 2020 and 1 July 2022: 65.7% of patients were male and had an average age of 68, while the female patients had an average age of 61. The mean interval of date of cardiology referral to surgery date was 9.7 working days, with 36% of patients referred within five days of the planned surgery date. Moreover, 39% had valvular surgery in combination with another type of cardiac surgery. No complications linked to dental aetiology were noted.Conclusions This paper raises questions about the advisability of oral surgery input before cardiac surgery for anything other than pain relief, management of acute dental sepsis, or IE whose source has been identified as an oral commensal. The COVID-19 pandemic has presented an opportunity to review current practice and open the way to developing a new approach which is patient-centred, safe, effective and efficient.

Abstract
Background Recently, anecdotal evidence suggested an increase in infective endocarditis (IE) in Manitoba driven by an increasing proportion of patients with intravenous drug use (IVDU)-associated endocarditis. This study aimed to characterize the observed changing incidence and epidemiology of IE. Methods This retrospective study evaluated consecutive patients >18 years old with an International Classification of Disease–10 diagnosis of IE who presented to a tertiary referral center in Winnipeg, Manitoba between January 1, 2004 and December 31, 2018. Data were obtained by individual review of paper and electronic medical records and entered into the Research Electronic Data Capture database. Mortality and hospital readmission data were acquired by linking Research Electronic Data Capture data to the Manitoba Centre for Health Policy, which prospectively maintains a comprehensive population-based health database. Results A total of 612 cases of IE were identified. The incidence of IE increased from 2.03 per 100,000 in 2004 to 5.16 per 100,000 in 2018, with IVDU-associated cases increasing from 0.11 to 2.87 per 100,000. Left heart vegetations were most common in the non-IVDU group, whereas right-sided vegetations dominated in the IVDU group. All-cause mortality did not differ between IVDU and non-IVDU IE, despite a significantly younger age in patients with IVDU. The IVDU group showed a higher rate of endocarditis recurrence. Conclusions In this first study to examine the longitudinal incidence of IE in Manitoba, we showed that the incidence of IE has significantly increased over the last 15 years, with a contribution of IVDU-associated IE that has a high rate of mortality and disease recurrence.

Abstract
AIMS Unruptured aortic root pseudoaneurysm (UARP) is a rare complication of aortic valve endocarditis. Infectious spread to the valvular annulus or myocardium can cause septic complications that manifest as wall thickening, and spontaneous abscess drainage leads to pseudoaneurysm formation. We report the first patient series in which transcatheter aortic valve implantation (TAVI) using a single valve-resolved aortic valvulopathy associated with UARP was performed. METHODS At our center, from December 2017 to October 2019, 138 patients underwent TAVI for aortic valve stenosis and/or regurgitation, 20 of whom (12 female patients, 8 male patients) had associated incidental UARP and were considered as our study population. The average age of these patients was 76.9 ± 5.2 years. All patients were assessed using preprocedural and postprocedural multimodality imaging, including transthoracic echocardiography, transesophageal echocardiography, and cardiac computed tomography angiography (CCTA). RESULTS In all cases, the final angiographic examination showed correct valve positioning with complete coverage of the false aneurysm. Post-TAVI CCTA showed presence of total or subtotal UARP thrombosis. The mean follow-up period was 17.5 months (12-23 months). During follow-up, imaging showed normal prosthetic valve function, no significant leakage (trace or mild), and complete UARP exclusion in all patients, without any complications. CONCLUSION In conclusion, percutaneous valve positioning can simultaneously solve pseudoaneurysm complications by excluding the sac and promoting thrombosis.

Abstract
OBJECTIVE Although the standard treatment of infective endocarditis (IE) is antimicrobial therapy, surgical intervention is required in some cases. However, the optimal timing of surgery remains unclear. Hence, we conducted a population-based analysis using the National Inpatient Sample (NIS) database to assess the outcomes of early versus late surgery in patients with native valve IE. METHODS We queried the NIS database for all hospitalized patients between 2006 and 2016 with a primary diagnosis of IE who had cardiac surgery. We stratified surgery as early ≤7 or late >7 days of admission. Multivariable logistic regression models were used to assess in-hospital mortality and postoperative complications. Length of stay (LOS) and total hospital cost (HC) were evaluated using multivariable log-normal regression models. RESULTS A total of 13 056 patients (57.6% in the early group and 42.4% in the late group) were included. The in-hospital mortality rate in the early group was 5.0% compared to 5.4% in the late intervention group (adjusted odds ratio, 1.20, 95% confidence interval [CI] 0.79-1.81). Overall median LOS was reduced in the early group by 48.2% (95% CI, 46.5%-49.9%, 12.4 days in the early group and 25.9 days in late group), as well as HC which was reduced in the early group by 28.3% (95% CI, 26.0%-30.6%). CONCLUSION Among patients with native valve IE who needed cardiac surgery, the time of surgical intervention did not affect the in-hospital mortality. However, early surgery was associated with significantly shorter LOS and lower HC.

Abstract
Establishment of the Heart Team concept in the field of cardiovascular medicine has resulted in quality improvement in the management of heart valve disease and heart failure. Similarly, the concept of an Endocarditis Team would be important in improving outcomes in patients with infective endocarditis (IE), given it is an uncommon clinical entity with general practitioners and low-volume centers lacking sufficient experience in its management. A multidisciplinary approach can substantially reduce the still unacceptably high morbidity and mortality in patients with IE, as it allows early diagnosis and appropriate comprehensive management. Decision-making within the Endocarditis Team must follow a standard protocol that is based on current clinical guidelines for the management of IE. If surgery is indicated, it is best performed sooner than later in most instances. Communication between referring hospitals and reference centers with an established Endocarditis Team must be smooth and definite protocols for transfer to experienced endocarditis centers with surgical facilities is essential. Follow-up and outpatient care following hospital discharge is crucial due to the possibility of residual infection and risk of development of recurrent endocarditis or heart failure, particularly within the first 2 years. Patient and health-care provider education is the mainstay for the accurate implementation of the Endocarditis Team concept. The following Keynote Lecture offers an overview of the current literature supporting the multidisciplinary management of IE and addresses multiple aspects related to the Endocarditis Team, highlighting its importance and necessity for the comprehensive treatment of this complex disease.

Abstract
This case report details the unique cause of death of a 37-year-old Caucasian woman with a history significant for intravenous drug abuse. Before her death, she complained of extremity weakness and pain. Although her death was discovered to be the result of endocarditis, her symptoms were similar to that of a stroke. Autopsy revealed a large endocardial vegetation infecting both the tricuspid and mitral valves and a patent foramen ovale. The subsequent embolization of this vegetation caused blockages in the lungs, liver, and brain. An acute embolization of these vegetations to the bilateral middle cerebral arteries is the cause of the stroke presentation. Other comorbidities, such as cardiomegaly, microscopic evidence of myocardial infarction, and atherosclerotic disease, also contributed to the cause of death. As the opioid crisis continues in the United States, it is important to review cases involving the effects of drug use. The multiple interactions between endocarditis and the aforementioned conditions are documented to not only serve as references for future autopsies but also for the treatment of patients who have similar symptoms and comorbidities.

Abstract
INTRODUCTION Infectious endocarditis (IE) is a potentially deadly disease without therapy and can cause a wide number of findings and symptoms, often resembling a flu-like illness, which makes diagnosis difficult. OBJECTIVE This narrative review evaluates the presentation, evaluation, and management of infective endocarditis in the emergency department, based on the most current literature. DISCUSSION IE is due to infection of the endocardial surface, most commonly cardiac valves. Major risk factors include prior endocarditis (the most common risk factor), structural heart damage, IV drug use (IVDU), poor immune function (vasculitis, HIV, diabetes, malignancy), nosocomial (surgical hardware placement, poor surgical technique, hematoma development), and poor oral hygiene, and a wide variety of organisms can cause IE. Patients typically present with flu-like illness. Though fever and murmur occur in the majority of cases, they may not be present at the time of initial presentation. Other findings such as Roth spots, Janeway lesions, Osler nodes, etc. are not common. An important component is consideration of risk factors. A patient with IVDU (past or current use) and fever should trigger consideration of IE. Other keys are multiple sites of infection, poor dentition, and abnormal culture results with atypical organisms. If endocarditis is likely based on history and examination, admission for further evaluation is recommended. Blood cultures and echocardiogram are key diagnostic tests. CONCLUSIONS Emergency physicians should consider IE in the patient with flu-like symptoms and risk factors. Appropriate evaluation and management can significantly reduce disease morbidity and mortality.

Abstract
Hemodialysis (HD) patients are more susceptible to infective endocarditis (IE) due to the increased risk of bacterial invasion through intravascular access. However, it remains unclear whether the causative organisms and outcomes of IE in HD patients differ from those in non-HD patients. This study clarified the differences in clinical presentation and outcomes between HD and non-HD patients. At our hospital, we performed a retrospective study of 39 HD and 51 non-HD patients with echocardiography-confirmed IE between June 2000 and February 2007. No differences in sex, intravenous drug use, previous diagnosis of congestive heart failure, and previous valvular surgery were observed between these two groups. The number of patients with diabetic mellitus in these two groups was significantly different (28.2% HD vs 5.9% non-HD patients). The C-reactive protein levels in the two groups were not significantly different. By contrast, the erythrocyte sedimentation rate was significantly higher in the HD patients (HD vs non-HD: 87.2±33.32 vs 52.96±28.19). The incidence of IE involving the mitral valve (MV; 45.1%) or the aortic valve (AV; 43.1%) was similar among the non-HD patients, whereas a preference of IE involving the MV (79.5%) over the AV (15.4%) was noted among the HD patients. The HD patients had a significantly higher Staphylococcus aureus infection rate (HD: 46.2%; non-HD: 27.5%). The proportion of methicillin-resistant S. aureus (MRSA; 83.8%) infection accounting for S. aureus IE in the HD group was higher than that (28.6%) in the non-HD group. The in-hospital mortality rate did not differ between the two groups. In conclusion, compared with non-HD patients, a propensity of IE involving the MV and a higher MRSA infection rate were observed in HD patients. The in-hospital mortality rate of echocardiography-confirmed IE did not differ between the two groups.

Abstract
Sixty years after its initial description, right-sided infective endocarditis (RSIE) still poses a challenge to all medical practitioners. Epidemiological data reveal a rising incidence attributable to the global surge in the number of intravenous drug users and the increased use of central vascular catheters and implantable cardiac devices. RSIE differs from left-sided infective endocarditis in more than just the location of the involved cardiac valve. They have different clinical presentations, diagnostic findings, and prognoses; hence, they require different management strategies. Cardiac murmurs and systemic emboli are usually absent in RSIE, whereas pulmonary embolism and its related complications dominate the clinical picture. Diagnostic delay of RSIE is secondary to the similarity in its initial presentation to other entities. Complications may ensue as a result of this delay. Diagnosis can be initially confirmed by using transthoracic echocardiography, except in patients with implanted cardioverter defibrillator, where a transesophageal echocardiogram is necessary. Various factors may increase mortality and morbidity in RSIE such as tricuspid valve vegetation size, fungal etiology, and low CD4 cell count in HIV patients. Oxacillin and vancomycin had been the traditionally used agents for the treatment of methicillin-susceptible and methicillin-resistant Staphylococcus aureus, respectively. More recently, daptomycin has shown promising results, which has led to its Food and Drug Administration (FDA) approval for the treatment of S. aureus bacteremia and associated RSIE. The aim of this article is to provide a comprehensive update on RSIE including epidemiology, pathogenesis, microbiology, diagnosis, management, and prognosis.

Abstract
OBJECTIVES Our purpose is to address whether antimicrobial prophylaxis is necessary before certain dental procedures for patients at increased risk for acquiring infective endocarditis (IE). METHODS We reviewed recommendations for IE prophylaxis made by the American Heart Association (AHA) from 1995 to the present time. We also compared and contrasted the current recommendations from the AHA, European Society of Cardiology (ESC), United Kingdom's National Institute for Health and Care Excellence (NICE) and a consortium of French organisations. We further reviewed recent papers that have observed the incidence of IE since these current recommendations were published. RESULTS Beginning in the 1990s, questions were raised about the advisability of using antimicrobial prophylaxis before certain dental procedures to prevent IE. Various groups in Europe and the US were increasingly aware that there were not any clinical trials showing the effectiveness, or lack thereof, of such prophylaxis. In the early to mid-2000s, the AHA, ESC and French consortium published guidelines recommending restriction of prophylaxis before dental procedures to patients with highest risk for developing IE and/or the highest risk for an adverse outcome from IE. The NICE guidelines eliminated recommendations for prophylaxis before dental procedures. Studies published after these changes were instituted have generally shown that the incidence of IE has not changed, although two recent reports have observed some increased incidence (but not necessarily related to an antecedent dental procedure). CONCLUSION A multi-national randomised controlled clinical trial that would include individuals from both developed and developing countries around the world is needed to ultimately define whether there is a role for antibiotic prophylaxis administered before certain dental procedures to prevent IE.

Abstract
PURPOSE We aimed to evaluate the utility of cardiac magnetic resonance imaging (MRI) for the diagnosis of infective endocarditis (IE). METHODS Sixteen patients with a preliminary diagnosis of IE (10 women and six men; age range, 4-66 years) were referred for cardiac MRI. MRI sequences were as follows: echo-planar cine true fast imaging with steady-state precession (true-FISP), dark-blood fast spin echo T1-weighted imaging, T2-weighted imaging, dark-blood half-Fourier single shot turbo spin echo (HASTE), and early contrast-enhanced first-pass fast low-angle shot (FLASH). Delayed contrast-enhanced images were obtained using three-dimensional inversion recovery FLASH after 15±5 min. The MRI features were evaluated, including valvular pathologies on cine MRI and contrast enhancement on the walls of the cardiac chambers, major thoracic vasculature, and paravalvular tissue, attributable to endothelial extension of inflammation on contrast-enhanced images. RESULTS Fourteen valvular vegetations were detected in eleven patients on cardiac MRI. It was not possible to depict valvular vegetations in five patients. Vegetations were detected on the aortic valve (n=7), mitral valve (n=3), tricuspid and pulmonary valves (n=1). Delayed contrast enhancement attributable to extension of inflammation was observed on the aortic wall and aortic root (n=11), paravalvular tissue (n=4), mitral valve (n=2), walls of the cardiac chambers (n=6), interventricular septum (n=3), and wall of the pulmonary artery and superior mesenteric artery (n=1). CONCLUSION Valvular vegetation features of IE can be detected by MRI. Moreover, in the absence of vegetations, detection of delayed enhancement representing endothelial inflammation of the cardiovascular structures can contribute to the diagnosis and treatment planning of IE.

Abstract
BACKGROUND We examined discharges for infective endocarditis (IE) at an academic teaching hospital for over 10 years to evaluate if an increase in hospitalizations for IE and increase in hepatitis C virus (HCV) in patients with IE could predict a new epidemic of injection drug use (IDU). MATERIALS AND METHODS Retrospective medical record review of discharged patients with the diagnosis of IE as defined by the modified Duke criteria. Student's t test, chi-squared test and Fisher's exact test were used to calculate P values. RESULTS There were 542 discharges among 392 unique patients with IE and 104 patients were readmitted 2-7 times. Of the total discharges, 367 (67.7%) were not screened for HCV, and of those tested, 86 (49.1%) were HCV+; 404 (74.5%) were not screened for HIV and of those tested, 28 (20.3%) were HIV+. Patients who self-identify as a person who injects drugs were more likely to be tested for HCV, 75 (69.4%) versus 12 (31.5%, P < 0.0001), and for HIV, 72 (66.6%) versus 13 (34.2%, P < 0.0001) compared with those who self-report no IDU. Those with a positive result for opiate or heroin toxicology test were more likely to be screened for HCV, 70 (66%) versus 22 (44.8%, P < 0.0001), and for HIV, 66 (62.2%) versus 25 (51%, P < 0.0001) than those with negative result for toxicology test. Over this period, there was a 2-fold increase in IE cases, a 3-fold increase in HCV antibody prevalence and a 6-fold increase in opiate toxicology screens showing positive result, but no increase in HIV. CONCLUSIONS Although IDU is a known risk factor for IE, the observation of a sharp increase in IE cases may signal a new epidemic of IDU and HCV.

Abstract
BACKGROUND With increasing prevalence of injected drug use in the United States, a growing number of intravenous drug users (IVDUs) are at risk for infective endocarditis (IE) that may require surgical intervention; however, few data exist about clinical outcomes of these individuals. METHODS We evaluated consecutive adult patients undergoing surgery for active IE between 2002 and 2014 pooled from 2 prospective institutional databases. Death and valve-related events, including reinfection or heart valve reoperation, thromboembolism, and anticoagulation-related hemorrhage were evaluated. RESULTS Of the 436 patients identified, 78 (17.9%) were current IVDUs. The proportion of IVDUs increased from 14.8% in 2002 to 2004 to 26.1% in 2012 to 2014. IVDUs were younger (aged 35.9 ± 9.9 years vs 59.3 ± 14.1 years) and had fewer cardiovascular risk factors than non-IVDUs. During follow-up (median, 29.4 months; quartile 1-3, 4.7-72.6 months), adverse events among all patients included death in 92, reinfection in 42, valve-reoperation in 35, thromboembolism in 17, and hemorrhage in 16. Operative mortality was lower among IVDUs (odds ratio, 0.25; 95% confidence interval [CI], 0.06-0.71), but overall mortality was not significantly different (hazard ratio [HR], 0.78; 95% CI, 0.44-1.37). When baseline profiles were adjusted by propensity score, IVDUs had higher risk of valve-related complications (HR, 3.82; 95% CI, 1.95-7.49; P < .001) principally attributable to higher rates of reinfection (HR, 6.20; 95% CI, 2.56-15.00; P < .001). CONCLUSIONS The proportion of IVDUs among surgically treated IE patients is increasing. Although IVDUs have lower operative risk, long-term outcomes are compromised by reinfection.

Abstract
OBJECTIVE To determine the incidence and predictors of infective endocarditis (IE) in a population-based cohort of patients with mitral valve prolapse (MVP). PATIENTS AND METHODS We identified all adult Olmsted County residents with MVP diagnosed by echocardiography from January 1989 to December 1998 and cross-matched them with the Rochester Epidemiology Project-identified Olmsted County cases of IE from January 1, 1986, through December 31, 2006. We retrospectively analyzed and de novo confirmed each IE case using the modified Duke criteria. RESULTS There were 896 Olmsted County residents with echocardiographically diagnosed MVP (mean age, 53±21 years; 565 women [63%]). The mean follow-up period was 11±5 years. The 15-year cohort risk of IE after MVP diagnosis was 1.1%±0.4% (incidence, 86.6 cases per 100,000 person-years; 95% CI, 43.3-173.2 cases per 100,000 person-years); thus, the age- and sex-adjusted relative risk of IE in patients with MVP was 8.1 (95% CI, 3.6-18.0) in comparison to the general population of Olmsted County (P<.001). There were no IE cases in patients without previously diagnosed mitral regurgitation (MR). Conversely, IE incidence was higher in patients with MVP with moderate, moderate-severe, or severe MR (289.5 cases per 100,000 person-years; 95% CI, 108.7-771.2 cases per 100,000 person-years; P=.02 compared with trivial, mild, or mild-moderate MR) and in patients with a flail mitral leaflet (715.5 cases per 100,000 person-years; 95% CI, 178.9-2861.0 cases per 100,000 person-years; P=.02 compared with no flail mitral leaflet). CONCLUSION The population-based incidence of IE in adults with MVP is higher than those previously reported in case-control, tertiary care center studies. Patients with MVP and moderate, moderate-severe, or severe MR or a flail mitral leaflet are at a notable risk of developing IE in comparison with those without MR.

Abstract
Infective endocarditis (IE) is a potentially fatal cardiac infection associated with an inhospital mortality rate of up to 22%. Fifty per cent of IE cases develop in patients with no known history of valve disease. It is therefore important to remain vigilant to the possibility of the diagnosis in patients with a febrile illness and unknown source. From a military perspective, our patients are unique due to the breadth of pathogens they are exposed to, and blood-culture-negative IE is a risk. In particular, there should be awareness of Coxiella burnetii as a possible causative pathogen. In this review we incorporate the latest consensus from systematic reviews and publications identified by a literature search through Medline. We describe the diagnosis and management of IE with particular reference to the military population.

Abstract
Infective endocarditis (IE) is a life-threatening disease associated with serious complications. The GBD 2010 (Global Burden of Disease, Injuries, and Risk Factors) study IE expert group conducted a systematic review of IE epidemiology literature to inform estimates of the burden on IE in 21 world regions in 1990 and 2010. The disease model of IE for the GBD 2010 study included IE death and 2 sequelae: stroke and valve surgery. Several medical and science databases were searched for IE epidemiology studies in GBD high-, low-, and middle-income regions published between 1980 and 2008. The epidemiologic parameters of interest were IE incidence, proportions of IE patients who developed stroke or underwent valve surgery, and case fatality. Literature searches yielded 1,975 unique papers, of which 115 published in 10 languages were included in the systematic review. Eligible studies were population-based (17%), multicenter hospital-based (11%), and single-center hospital-based studies (71%). Population-based studies were reported from only 6 world regions. Data were missing or sparse in many low- and middle-income regions. The crude incidence of IE ranged between 1.5 and 11.6 cases per 100,000 people and was reported from 10 countries. The overall mean proportion of IE patients that developed stroke was 0.158 ± 0.091, and the mean proportion of patients that underwent valve surgery was 0.324 ± 0.188. The mean case fatality risk was 0.211 ± 0.104. A systematic review for the GBD 2010 study provided IE epidemiology estimates for many world regions, but highlighted the lack of information about IE in low- and middle-income regions. More complete knowledge of the global burden of IE will require improved IE surveillance in all world regions.

Abstract
INTRODUCTION Infective endocarditis (IE) is a serious disease whose prognosis depends on early management. Aortic location is characterized by its evolution toward myocardial failure and the high number of complications reasons for early surgery. AIM To compare the short- and mid-terms results of surgery for aortic infective endocarditis (IE) in the active phase and the healed phase. PATIENTS AND METHODS We analyzed retrospectively the data of 48 consecutive patients operated for aortic infective endocarditis between January 2000 and January 2012. The data on operative mortality, morbidity and major cardiovascular events (mortality, recurrent endocarditis, reintervention, and stroke) were analyzed. RESULTS Twenty-three patients (48%) underwent surgery during the active phase (group I), 19 on native and 4 on prosthetic valves, and 25 patients (52%) were operated during healed endocarditis (group II) only on native valve. Mean age was 39 years (12-81) with a male predominance (83%). Rheumatic valvular disease was the main etiology of underlying valvular disease in both groups (85%). The clinical feature was dominated by signs of cardiogenic shock in group I and dyspnea exertion stage III-IV NYHA in group II. Streptococcus and Staphylococcus germs were most frequently encountered. Indication for surgery was heart failure in group I, it was related to the symptoms, the severity of valvular disease and its impact on the left ventricle in group II. An aortic valve replacement with a mechanical prosthesis was performed in the majority of cases (83%). Postoperative mortality concerned only one patient in group I. Twenty-one patients (44%) were followed for a mean of 30 months (1-72). One patient in group II died following cerebral hemorrhagic stroke related to accident with vitamin K antagonist. In both groups, there was an improvement in the functional class. No recurrence of endocarditis was noted in both groups during follow-up. CONCLUSION The prognosis of infective endocarditis of the aortic valve is severe due to the fast progression to heart failure. Early medical and surgical approach provides good results on morbidity and mortality in the short- and mid-terms.

Abstract
Infective endocarditis (IE) is a noncontagious infection of the endocardium and heart valves. The epidemiology of IE has shifted recently with an increase in health care-associated IE. Infective endocarditis requiring intensive care unit stay is increasing, and nosocomial IE is frequently responsible. Diagnosis of IE requires multiple clinical data points encompassing history and physical examination, microbiology, and cardiac imaging as no one test is sufficiently sensitive or specific. The modified Duke criteria algorithm is the standard of care in the clinical diagnosis of IE. Complications from IE are common, particularly so in the critical care setting, and include congestive heart failure, embolism, septic shock, invasive infection, prosthetic valve dehiscence, heart block, and mycotic aneurysm. A multidisciplinary care team of infectious disease, cardiology, and cardiac surgery physicians is recommended to reduce complications. Intravenous antibiotics are first-line therapy with cardiac surgery being reserved for certain complications of IE and/or for clinical situations in which there is a high risk of complications. Timing of surgery for IE remains controversial and depends on a variety of clinical factors.

Abstract
OBJECTIVES Guidelines for diagnosis of infective endocarditis are largely based upon epidemiological studies in referral hospitals. Referral bias, however, might impair the validity of guidelines in non-referral hospitals. Recent studies in non-referral care centres on infective endocarditis are sparse. We conducted a retrospective epidemiological study on infective endocarditis in a large non-referral hospital in a Belgian city (Kortrijk). METHODS The medical record system was searched for all cases tagged with a putative diagnosis of infective endocarditis in the period 2003-2010. The cases that fulfilled the modified Duke criteria for probable or definite infective endocarditis were included. RESULTS Compared to referral centres, an older population with infective endocarditis, and fewer predisposing cardiac factors and catheter-related infective endocarditis is seen in our population. Our patients have fewer prosthetic valve endocarditis as well as fewer staphylococcal endocarditis. Our patients undergo less surgery, although mortality rate seems to be highly comparable with referral centres, with nosocomial infective endocarditis as an independent predictor of mortality. CONCLUSION The present study suggests that characteristics of infective endocarditis as well as associative factors might differ among non-referral hospitals and referral hospitals.

Abstract
Infective endocarditis (IE) is among the most severe infectious disease, the prevention of which has not decreased its incidence. The age of patients and the rate of health care-associated IE have increased as a consequence of medical progress. The prevention strategies have been subjected to an important debate and nonspecific hygiene measures are now placed above the use of antibiotic prophylaxis. Indeed, the level of evidence of antibiotic prophylaxis efficiency is low and the indications of its prescription have been restricted in the recent international guidelines. In cases carrying a high suspicion of IE, efforts should be made to rapidly identify patients with a definite or highly probable diagnosis of IE and to find the causative pathogen to ensure that appropriate treatment, including urgent valvular surgery, begins promptly. Although echocardiography remains the main accurate imaging modality to identify endocardial lesions associated with IE, it can be negative or inconclusive especially in cases of prosthetic valve or other intracardiac devices. Recent studies demonstrated the diagnostic value of other imaging strategies including cardiac computed tomography (CT), positron emission tomography/CT, radiolabelled leukocyte single-photon emission CT/CT, and cerebral magnetic resonance imaging. Novel perspectives on the management of endocarditis are emerging and offer a hope for decreasing the rate of residual deaths by accelerating the processes of diagnosis, risk stratification, and instauration of antimicrobial therapy. Moreover, the rapid transfer of high-risk patients to specialized mediosurgical centres (IE team), the development of new surgical modalities, and close long-term follow-up are of crucial importance.

Abstract
Cardiac infections include a group of conditions involving the heart muscle, the pericardium, or the endocardial surface of the heart. Infections can extend to prosthetic material or the leads in case of the implantation of devices. Despite their relative low incidence, these conditions that are associated with high morbidity and mortality involve a relevant burden of diagnostic workup. Early diagnosis is crucial for adequate management of patient, as early treatment improves the prognosis; unfortunately, the clinical manifestations are often nonspecific. Accurate and timely diagnosis typically requires the correlation of imaging findings with laboratory data. (18)F-FDG-PET is a well-established imaging modality for the diagnosis and management of malignancies, and evidence is also increasing regarding its value for assessing infectious and inflammatory diseases. This article summarizes published evidence on the usefulness of (18)F-FDG-PET for the diagnosis of cardiac infections, mainly focused on endocarditis and cardiovascular device infections. Nevertheless, the diagnostic potential of (18)F-FDG-PET in patients with pericarditis and myocarditis is also briefly reviewed, considering the most likely future advances and new perspectives that the use of PET/magnetic resonance would open in the diagnosis of such conditions.

Abstract
BACKGROUND Cerebral complications are well-identified causes of morbidity and mortality in patients with infective endocarditis (IE). Few studies have analysed the impact of brain magnetic resonance imaging (MRI) in IE patients with neurological manifestations. OBJECTIVES The aims of this study were to assess the MRI contribution to the management of patients with IE neurological manifestations and to compare cerebral CT and MRI findings. MATERIAL AND METHODS Patients with definite or probable IE and neurological manifestations were prospectively enrolled from 2005 to 2008, in a university hospital (Bichat Claude Bernard Hospital, Paris). Clinical and radiological characteristics and echocardiographic findings were systematically recorded. Brain MRI with angiography was performed and compared to available CT scans. The contribution of MRI results to cerebral involvement staging and to therapeutic plans was evaluated. RESULTS Thirty patients, 37-89 years old, were included. Nineteen suffered from pre-existing heart disease. Blood cultures were positive in 29 cases and the main micro-organisms were streptococci (n = 14) and staphylococci (n = 13). The IE was mainly located on mitral (n = 15) and aortic valves (n = 13). Neurological events were strokes (n = 12), meningitis (n = 5), seizures (n = 1), impaired consciousness (n = 11) and severe headache (n = 1). MRI findings included ischaemic lesions (n = 25), haemorrhagic lesions (n = 2), subarachnoid haemorrhage (n = 5), brain abscess (n = 6), mycotic aneurysm (n = 7), vascular occlusion (n = 3) and cerebral microbleeds (n = 17). In 19/30 cases, neurological manifestations were observed before the diagnosis of IE. MRI was more sensitive than CT scan in detecting both clinically symptomatic cerebral lesions (100 and 81%, respectively) and additional asymptomatic lesions (50 and 23%, respectively). Therapeutic plans were modified according to MRI results in 27% of patients: antibiotherapy regimen modifications in 7% (switch for molecules with high cerebral diffusion) and surgical plan modifications in 20% (indication of valvular replacement due to the embolic nature of the vegetations revealed by MRI or postponement of surgery due to haemorrhagic lesions). None of the 16/30 (51%) operated-on patients experienced postoperative neurological worsening. In-hospital death occurred in 4 patients. CONCLUSION In patients with IE neurological manifestations, MRI revealed a broader involvement of the brain (type and number of lesions) than indicated by clinical signs and/or CT scan. With a better disease staging of neurological manifestations, MRI brain imaging may help in patient management and the decision-making process especially for cardiac surgery indication and timing of valve replacement.

Abstract
OBJECTIVES Few studies have examined the use of stentless Freestyle bioprostheses in patients with active valve endocarditis (VE). The aim of this study was to evaluate outcomes of stentless Freestyle bioprostheses in patients undergoing full-root replacement. METHODS From February 2000 to June 2010, 180 patients with VE underwent cardiac surgery at our institution, of which 71 (39.5%) had prosthetic VE. Eighteen patients underwent full-root replacement with Freestyle bioprostheses: 3 patients (16%) had native aortic VE, 14 (78%) had aortic prosthetic VE and 1 (6%) had mitral and aortic prosthetic VE. Mean age was 66.7 ± 10.1, M/F: 6/12, mean logistic EuroSCORE 36.4 ± 21.6. Eight patients (42%) underwent concomitant procedures (two mitral valve replacements, three ascending aorta replacements, one coronary artery bypass grafting (CABG), one ventricular septal disease (VSD) repair, one CABG + ascending aorta + VSD repair). RESULTS Two patients (11%) died in-hospital. At the median follow-up of 24 months (range 1-113 months), no death occurred and freedom from reoperation was 87.5% (2 patients for aortic root pseudo-aneurysm at 1 and 23 months). All patients are in NYHA functional class I and have satisfactory echocardiographic data (EF 54.3 ± 8%, peak and mean trans-prosthetic gradients 12 ± 6.7 mmHg and 7.5 ± 3.6 mmHg) with 100% freedom recurrence of VE. CONCLUSIONS Our experience shows that root replacement with Freestyle stentless bioprostheses in patient with VE, is associated with low rates of early and mid-term mortality, good haemodynamic performance and low rates of valve-related morbidity as well as low recurrence of infection.

Abstract
Echocardiography is the major imaging modality used for the diagnosis of infective endocarditis (IE). It is also useful in detecting the complications of IE which often necessitate surgical intervention and strongly influence patient outcomes. Transesophageal echocardiography (TEE), with proven superiority over transthoracic echocardiography (TTE) for the detection of vegetations and complications such as abscess, should be performed in the vast majority of cases especially when TTE image quality is poor or implanted devices are present. Three-dimensional (3D) TEE provides enhanced display of anatomic-spatial relationships allowing more precise delineation of complex pathology, particularly of the mitral valve and annulus. Importantly, echocardiographic findings can be non-specific and should always be interpreted in the context of the pre-test probability of IE based on careful clinical assessment. IE remains a challenging disease associated with variable clinical presentations, and high mortality. Whenever IE is suspected, echocardiography should be utilized early for both diagnosis and detection of complications.

Abstract
OBJECTIVE To determine clinical, echocardiographic features, management and outcomes of patients presenting peri aortic abscess complicating infective endocarditis (IE) and demonstrate the impact of periaortic abscess on morbidity and mortality of these patients. METHODS We have analyzed clinical, microbiological, echocardiographic aspects, therapies and outcomes of patients with aortic abscess occurring during IE, and we compared these data with those of patients presenting IE without peri aortic abscess in the same period in the cardiology department of the University Hospital of Marrakech from January 2006 to January 2010. RESULTS Above 56 cases of infective endocarditis, 16 patients had an aortic abscess. Mean age was 33 ± 11 years with a clear male predominance in the group IE with abscess versus IE without abscess. Heart failure was noted in all patients in periaortic abscess group, and was more severe in this group compared to control. Streptococcus and staphylococcus predominated with no significant difference between the two groups. Transthoracic echocardiography coupled with transesophageal echocardiography made the diagnosis of aortic abscess witch was isolated in 11 cases and associated with other complications in five cases. In terms of complications, splenic infarction was more frequent in the group with abscess (25 versus 2.5%, P<0.05). There was not a significant difference between the two groups for the others complications. Surgery associated with a double antibiotic therapy was the standard treatment with a variable delay for surgery of four days to four weeks. Hospital mortality in the acute phase was higher in periaortic abscess group (37% versus 10%, P<0.05). The evolution of survivors at six months was favorable. CONCLUSION Periaortic abscess complicating IE is associated with a high morbidity and mortality in spite of modern approach as well as on medical or surgical treatment. It requires therefore a strict monitoring of patients with infective endocarditis.

Abstract
Despite improvements in medical and surgical therapies, infective endocarditis is associated with poor prognosis and remains a therapeutic challenge. Many factors affect the outcome of this serious disease, including virulence of the microorganism, characteristics of the patients, presence of underlying disease, delays in diagnosis and treatment, surgical indications, and timing of surgery. We review the strengths and limitations of present therapeutic strategies and propose future directions for better management of endocarditis according to the most recent research. Novel perspectives on the management of endocarditis are emerging and offer hope for decreasing the rate of residual deaths by accelerating the process of diagnosis and risk stratification, reducing delays in starting antimicrobial therapy, rapid transfer of high-risk patients to specialised medico-surgical centres, development of new surgical methods, and close long-term follow-up.

Abstract
OBJECTIVES The aim of this study was to evaluate the incidence and epidemiological characteristics of infective endocarditis (IE) in the Czech Republic. These results represent the first data on the epidemiology of IE from the post-communist countries. METHODS This was a prospective multi-centre observational study monitoring the occurrence of IE in the catchment areas of 29 hospitals during a 12-month period. The total monitored territory involved a population of 3.9 million people (37.7% of the total Czech population). Patients were included in the study if they had a diagnosis of possible or definite endocarditis according to the modified Duke criteria. RESULTS One hundred and thirty-four episodes of IE in 132 patients were reported. Thus the crude incidence of IE was 3.4 cases/100,000 inhabitants/y. Vegetations were most frequently found on the aortic and mitral valves. The most frequent agent was Staphylococcus aureus (29.9%). The aetiology remained unexplained in 33.6% of cases, mainly because of previous antibiotic therapy. Surgical intervention during antibiotic therapy was performed in 36 patients (27.5%). Thirty-six patients died during hospitalization (in-hospital mortality rate 27.5%). The most common predisposing cardiac factors were remote cardiac surgery (19.4%) and degenerative valvular changes (11.9%). The most common extracardiac factors were pyogenic infections of skin and soft tissues (13.0%) and chronic haemodialysis (8.2%). CONCLUSIONS Our results document the changing epidemiological characteristics of IE, namely an increasing incidence of the disease and an increasing role of Staphylococcus aureus as a major pathogen. A shift was evident in predisposing factors for IE: almost 39% of IE episodes were associated with both cardiac and extracardiac modern medical procedures.

Abstract
Infective endocarditis (IE) remains a serious and deadly disease. The incidence, which varies by gender and on the presence of predisposing factors, has not decreased, due in part to the aging population with more healthcare exposures and predisposing risk factors such as prosthetic heart valves and intracardiac devices. The most important aspects of treatment in IE hinge upon early diagnosis, microorganism identification with susceptibility testing, and early initiation of appropriate antibiotic therapy. In addition, echocardiographic imaging is critical for both diagnostic and prognostic purposes. Early evaluation for surgery should be considered. Once a therapeutic strategy is begun, careful attention to the clinical course is necessary to ensure appropriate response to therapy and to identify complications early.

Abstract
In industrialized countries, after the eradication of rheumatic fever, rheumatic valve diseases progressively disappeared and the proportion of post-rheumatic infective endocarditis (IE) significantly decreased. Intravenous drug use, prosthetic valves, degenerative valve sclerosis, and invasive procedures have become the most important risk factors for IE. These changes also resulted in a decreasing incidence of streptococcal IE, which was compensated by an increased incidence of staphylococcal IE.

Abstract
Bacterial virulence could be altered by the antimicrobial agents of the host. Our aim was to identify the damage and survival of Streptococcus sanguinis induced by lysozymes in vitro and to analyse the potential of oral microorganisms to shirk host defences, which cause infective endocarditis. S. sanguinis ATCC 10556 received lysozyme at concentrations of 12.5, 25, 50 and 100 microg/ml. Cells were examined by electron microscopy. The survival was assessed by colony counting and construction of a growth curve. Challenged by lysozymes, cells mainly exhibited cell wall damage, which seemed to increase with increasing lysozyme concentration and longer incubation period in the presence of ions. Cells with little as well as apparent lesion were observed under the same treatment set, and anomalous stick and huge rotund bodies were occasionally observed. After the removal of the lysozyme, some damaged cells could be reverted to its original form with brain heart infusion (BHI), and their growth curve was similar to the control cells. After further incubation in BHI containing lysozyme, S. sanguinis cell damage stopped progressing, and their growth curve was also similar to the control cells. The results suggested that the S. sanguinis lesions caused by the lysozyme in the oral cavity may be nonhomogeneous and that some damaged cells could self-repair and survive. It also indicated that S. sanguinis with damaged cell walls may survive and be transmitted in the bloodstream.

The patient had history of untreated ventricular septal defect (VSD) and complained of severe dyspnea and orthopnea. Transthoracic and transesophageal echocardiograms revealed severe pulmonary regurgitation with large, hypermobile vegetation on pulmonary valve and right ventricular outflow tract (RVOT), and a small subarterial type VSD. Emergency operation was done due to rapid deterioration of the patient, and after 6 weeks of antibiotics coverage, he was discharged.

Abstract
Acute infective endocarditis is a complex disease with changing epidemiology and a rapidly evolving knowledge base. To consistently achieve optimal outcomes in the management of infective endocarditis, the clinical team must have an understanding of the epidemiology, microbiology, and natural history of infective endocarditis, as well as a grasp of guiding principles of diagnosis and medical and surgical management. The focus of this review is acute infective endocarditis, though many studies of diagnosis and treatment do not differentiate between acute and subacute disease, and indeed many principles of diagnosis and management of infective endocarditis for acute and subacute disease are identical.

Abstract
Acinetobacter is a highly resistant microorganism, commonly isolated in intensive and post-operative care units. Although rarely reported, it may constitute 1 of the several causes of early prosthetic valve endocarditis. A diffuse, red maculopapular rash may be encountered in patients with Acinetobacter endocarditis. Here we present a case of early prosthetic valve endocarditis due to Acinetobacter baumannii and accompanied by a cutaneous eruption.

Abstract
Infective endocarditis (IE) is a rare but life-threatening infection. Bacteremia with organisms known to cause IE occurs commonly in association with invasive dental origin. Despite daily oral activities as well as professional dental treatments inducing bacteremia and the dental bacteremia as a risk factor of IE, the details of dental bacteria in the pathogenesis of IE are far from elucidation to date. How do a few microorganisms survive host defenses or escape from antibiotic attacking to seed target organs and cause distant infections? Why are Gram-positive bacteria more frequently detected than Gram-negative bacteria in IE? Cell wall-deficient bacteria (CWDB) were traditionally defined as bacteria with altered morphology and consistent with damaged or absent cell wall structures identified by EM. A number of case reports and laboratory studies suggest that CWDB may be found in the peripheral blood of patients with IE, and may also be demonstrated in vegetations on the valves of patients with IE. CWDB, in vitro, are resistant to antibiotics that act on cell wall biosynthesis. Recent studies indicate that the Streptococcus mutans (S. mutans) strains, the major cariogenic bacterium, isolated from the infected valve were deficient in some wall-associated proteins which are main cariogenic virulence of S. mutans, and the deficient stains exhibited less susceptible to antibiotics that act on cell wall biosynthesis. Further, the cloned deficient mutans were less susceptible to phagocytosis by human polymorphonuclear leukocytes but to possess higher platelet aggregation properties than their parent strains. As outlined above, we hypothesize that defect of cell wall construction may shield oral bacteria's survival in bloodstream and cause IE.

Abstract
The aim of this study was to evaluate the accuracy of procalcitonin (PCT) in predicting infective endocarditis (IE). 23 adult patients with IE, 30 patients with sepsis and 30 with tick-borne encephalitis were included in this prospective study. The PCT serum level, C-reactive protein (CRP), total leukocyte, and immature polymorphonuclear (PMN) cell counts were determined on admission, prior to the institution of antibiotic therapy, and compared according to the diagnosis. The median PCT level in patients with IE endocarditis was 0.81 ng/ml, in patients with sepsis it was 43.74 ng/ml, and in the group with viral infection it was 0.25 ng/ml (P < 0.001). The highest PCT level was found in patients with Staphylococcus aureus endocarditis. The area under the receiver operating characteristic curve that used PCT to predict IE was 0.722 (95% CI 0.572-0.873), compared with 0.909 (95% CI 0.829-0.989) for CRP, 0.699 (95% CI 0.551-0.846) for immature PMN cell count, and 0.619 (95% CI 0.468-0.770) for leukocyte count. Our study fails to demonstrate superiority of PCT as a diagnostic laboratorial parameter in predicting IE compared to CRP.
