Intraoperative Polymerase Chain Reaction from Cardiac Valve Tissue Is Beneficial for Guiding Further Therapy in Patients with Infective Endocarditis. J Clin Med 2024; 13:4319. [PMID: 39124586 PMCID: PMC11313656 DOI: 10.3390/jcm13154319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Revised: 07/07/2024] [Accepted: 07/18/2024] [Indexed: 08/12/2024] Open
Abstract
Background: Infectious endocarditis (IE) remains a critical condition despite all the medical advances in recent decades. Reliable pathogen identification is indispensable for precise therapy. The aim of this study was to evaluate the diagnostic and therapeutic benefit of additional polymerase chain reaction (PCR) in comparison with microbiological culture alone based on intraoperative tissue sampling for patients operated on due to IE. Methods: A total of 224 patients diagnosed with acute or subacute IE were analyzed. Intraoperatively resected infectious tissue was analyzed using both PCR and microbiological culture. Subsequently, the results of the detection of bacteria obtained based on intraoperative measurements from tissue via culture and PCR were compared with preoperative blood culture results. Furthermore, we evaluated the therapeutic impact of the culture and/or PCR results obtained from cardiac tissue. Results: The 224 patients were 63 ± 17 years old, and 64 (29%) were female. In total, 149 (67%) suffered from aortic valve endocarditis, 45 (45%) had mitral valve endocarditis, and 39 (18%) were afflicted with double-valve endocarditis. Prosthetic valve endocarditis was present in 70 (31%) patients. Pathogens were detected in 70% of the cases analyzed via PCR using cardiac valve tissue and in 25% of those analyzed via a culture of cardiac valve tissue; this figure was only 64% for preoperative blood culture. Overall, a pathogen was identified in 197 patients (88%), leading to antibiotic therapy. Targeted antibiotic therapy, based on the PCR results, was carried out in 37 cases and was conducted based on a culture from cardiac valve tissue in three cases. Finally, in 12% of patients, the causative pathogen remained unclear. Conclusions: For patients suffering endocarditis, PCR analysis is indispensable and superior to preoperative blood culture and intraoperative culture in detecting bacteria. Based on PCR testing, antibiotic therapy can be individually adjusted. The high precision of pathogen identification may lead to a significant reduction in IE-associated morbidity and mortality.

J Cardiothorac Surg 2024; 19:463. [PMID: 39034421 PMCID: PMC11261816 DOI: 10.1186/s13019-024-02946-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Accepted: 06/29/2024] [Indexed: 07/23/2024] Open
Abstract
BACKGROUND Infective endocarditis (IE) is a dangerous and lethal illness with high mortality rates. One of the main indications for surgery according to the guidelines is prevention of embolic events. However, uncertainty remains concerning the timing of surgery and the effect of early surgery in combination with antibiotic therapy versus antibiotic therapy alone in IE patients with a vegetation size > 10 mm. METHODS We conducted a comprehensive review by searching the PubMed, MEDLINE, and EMbase databases. Titles and abstracts were screened, and studies of interest were selected for full-text assessment. Studies were selected for review if they met the criteria of comparing surgical treatment + antibiotic therapy to antibiotic therapy alone in patients with vegetations > 10 mm. RESULTS We found 1,503 studies through our database search; nine of these were eligible for review, with a total number of 3,565 patients. Median age was 66 years (range: 17-80) and the median percentage of male patients was 65.6% (range: 61.8 - 71.4%). There was one randomised controlled trial, one prospective study, and seven retrospective studies. Seven studies found surgery + antibiotic therapy to be associated with better outcomes in patients with IE and vegetations > 10 mm, one of them being the randomised trial [hazard ratio = 0.10; 95% confidence interval 0.01-0.82]. Two studies found surgery + antibiotic therapy was associated with poorer outcomes compared with antibiotic therapy alone. CONCLUSION Overall, data vary in quality due to low numbers and selection bias. Evidence is conflicting, yet suggest that surgery + antibiotic therapy is associated with better outcomes in patients with IE and vegetations > 10 mm for prevention of emboli. Properly powered randomised trials are warranted.

Abstract
BACKGROUND Talaromyces marneffei (T. marneffei) is a thermal dimorphic fungus, which can cause lung or blood stream infection in patients, often life-threatening. However, endocarditis caused by T. marneffei has not been reported. For elderly patients with implanted cardiac devices or artificial valves, the prevention and treatment of infective endocarditis should not be ignored. METHODS This is a descriptive study of a T. marneffei endocarditis by joint detection of cardiac ultrasound examination, peripheral blood DNA metagenomics Next Generation Sequencing (mNGS), and in vitro culture. RESULTS We describe an 80-year-old female patient with an unusual infection of T. marneffei endocarditis. After intravenous drip of 0.2 g voriconazole twice a day for antifungal treatment, the patient showed no signs of improvement and their family refused further treatment. CONCLUSION Infective endocarditis is becoming more and more common in the elderly due to the widely use of invasive surgical procedures and implantation of intracardiac devices. The diagnosis and treatment of T. marneffei endocarditis is challenging because of its rarity. Here, we discussed a case of T. marneffei endocarditis, and emphasized the role of mNGS in early diagnosis, which is of great significance for treatment and survival rate of patients.

Abstract
BACKGROUND We noted a recent increase in cases of infective endocarditis (IE) at our institution. The purpose of the study is to examine the incidence, risk factors, microbiology and outcome of IE in our pediatric population. METHODS Retrospective review of IE cases during 2002-2020 at Children's Hospital of Michigan, Detroit. RESULTS 68 patients with IE were identified. There was a 2-fold increase in incidence during the 2012-2020 (late period) compared to the 2002-2011 (early period). The most common predisposing conditions were congenital heart disease (CHD) in 39 (57.4%) and central venous catheter (CVC) in 19 (27.9%). CHD was more frequent in the late period (29/43, 67.4%) compared to early period (10/25, 40.0%) (p = 0.042). In CHD patients, palliative or corrective cardiac surgery was performed prior to IE diagnosis in 4/25 (16%) in early period and 23/43 (53.5%) in the late period (p = 0.004). S. aureus was the most common causative organism (35.3%) followed by streptococci (22.1%). Valve replacement or valvuloplasty was performed in 22.1% of patients. Complications occurred in 20 (29.4%). Mortality occurred in 7 (10.3%): 3 had CHD, 3 had CVC and underlying conditions and 1 had fulminant MRSA infection. CONCLUSION(S) The higher incidence of IE during the late period is likely due to an increase in patients with CHD who had undergone prior cardiac surgery. S. aureus was the predominant pathogen in all patients including those with CHD, followed by streptococci. IE in children continues to be associated with high rates of morbidity and mortality.

Abstract
Infective endocarditis (IE) is associated with high morbidity and mortality. Early diagnosis is crucial for adequate patient management. Due to difficulties in the diagnosis, a multidisciplinary discussion in addition to the integration of clinical signs, microbiology data, and imaging data is used. Imaging, including echocardiography, molecular imaging techniques, and coronary CT angiography (CTA) is central to detect infections involving heart valves and implanted cardiovascular devices, also allowing for early detection of septic emboli and metastatic. This article describes the main clinical application of white blood cell SPECT/CT and [18F]FDG-PET/CT and CTA in IE and infections associated with cardiovascular implantable electronic devices.

Abstract
Introduction Literature regarding outcomes and predictors of complications secondary to infective endocarditis (IE) is limited. We aimed to study the outcomes and predictors of complications of IE. Methods Data from a national emergency department sample, which constitutes 20% sample of hospital-owned emergency departments in the USA, were analyzed for hospital visits for IE. Complications of endocarditis were obtained by using ICD codes. Multivariable generalized linear method was used to evaluate predictors of in-hospital mortality and complications. Results Out of 255,838 adult IE patients (mean age 60.3 ± 20.1 years, 48.5% females), 97,803 (38.2%) patients developed one or more major complications. The major complications were cardiovascular system complications [57,900 (22.6%)], neurologic [42,851 (16.7%)] complications, and renal [16,236 (6.4%)] complications. These included cardiogenic shock [3873 (1.5%)], septic shock [25,798 (10.1%)], acute heart failure [35,602 (14%)], systemic thromboembolism (STE) [21,390 (8.36%)], heart block [11,430 (4.47%)], in-hospital dialysis [2880 (1.1%)], and disseminated intravascular coagulation (DIC) [2704 (1.1%)]. Patients with complicated IE had risk of mortality (adjusted RR 1.12, 95% CI 1.11–1.13, p < 0.001). The complications strongly associated with mortality were septic shock (RR 1.29, 95% CI 1.27–1.30, p < 0.001), cardiogenic shock (RR 1.24, 95% CI 1.20–1.29, p < 0.001), DIC (RR 1.4, 95% CI 1.35–1.46, p < 0.001), and STE (RR 1.07, 95% CI 1.05–1.08, p < 0.001). Staphylococci were the predominant causative organisms (30.8%) among the complicated IE subgroups with higher associated mortality (42.8%). The main predictors of complications from IE were congenital heart disease, history of congestive heart failure, high Elixhauser comorbidity profile, staphylococcal infection, and fungal infections. The prevalence of cardiogenic shock increased over the study years from 1.13 to 1.98% (p-trend 0.04).
Conclusion Complicated IE is not uncommon and is associated with significant mortality. Staphylococcal infections were associated with high mortality rates. There has been an increasing trend of cardiogenic shock among IE patients across the US. Further research is needed to improve the outcomes of complicated endocarditis.

Abstract
Cardioaortic embolism to the brain accounts for approximately 15-30% of ischaemic strokes and is often referred to as 'cardioembolic stroke'. One-quarter of patients have more than one cardiac source of embolism and 15% have significant cerebrovascular atherosclerosis. After a careful work-up, up to 30% of ischaemic strokes remain 'cryptogenic', recently redefined as 'embolic strokes of undetermined source'. The diagnosis of cardioembolic stroke remains difficult because a potential cardiac source of embolism does not establish the stroke mechanism. The role of cardiac imaging-transthoracic echocardiography (TTE), transoesophageal echocardiography (TOE), cardiac computed tomography (CT), and magnetic resonance imaging (MRI)-in the diagnosis of potential cardiac sources of embolism, and for therapeutic guidance, is reviewed in these recommendations. Contrast TTE/TOE is highly accurate for detecting left atrial appendage thrombosis in patients with atrial fibrillation, valvular and prosthesis vegetations and thrombosis, aortic arch atheroma, patent foramen ovale, atrial septal defect, and intracardiac tumours. Both CT and MRI are highly accurate for detecting cavity thrombosis, intracardiac tumours, and valvular prosthesis thrombosis. Thus, CT and cardiac magnetic resonance should be considered in addition to TTE and TOE in the detection of a cardiac source of embolism. We propose a diagnostic algorithm where vascular imaging and contrast TTE/TOE are considered the first-line tool in the search for a cardiac source of embolism. CT and MRI are considered as alternative and complementary tools, and their indications are described on a case-by-case approach.

Abstract
RATIONAL Infective endocarditis (IE) is defined as an infection of the endocardial surface of the heart, which may include one or more heart valves, the mural endocardium. PATIENT CONCERNS A 53-years-old man with a history of alcohol abuse was admitted in hospital for fever, paroxysmal atrial fibrillation cardioverted by Amiodarone and pulmonary infection. DIAGNOSIS A case of recurrent severe endocarditis, with neurological complications both ischemic and hemorrhagic and heart failure caused by Streptococcus agalactiae in healthy man we reported. INTERVENTIONS Surgery was performed 2 weeks after admission. OUTCOMES The onset of intracranial hemorrhage delayed second cardiac surgery and the patient died because of end-stage heart failure. CONCLUSIONS Infective endocarditis caused by S. agalactiae is very rare, particularly in patients without underlying structural heart disease. This study showed that IE due to S. Agalactiae is a disease with high mortality when associated with neurological complication, heart failure but especially when it is recurrent and hits valve prosthesis.

Abstract
Infective endocarditis (IE) is a complex disease with cardiac involvement and multiorgan complications. Its prognosis depends on prompt diagnosis that leads to an aggressive therapeutic management combining antibiotic therapy and early cardiac surgery when indicated. However, IE diagnosis always poses a challenge, and echocardiography remains diagnostically imperfect in cases of prosthetic valve IE or cardiac implantable electronic device infection. In recent years, other imaging modalities (computed tomography, magnetic resonance imaging, nuclear imaging) have experienced significant technical improvements, and their application to the detection of cardiac and extracardiac IE-related lesions seems to be a strategic way forward in the management of patients with suspected IE. However, the scientific evidence in the literature remains limited; current guidelines address the use of the multimodality imaging in the field of IE with caution; the incremental value of each technique and their combinations is debated; and their use varies across countries. Despite these limitations, healthcare providers and surgeons should be aware of the possibilities offered by the multimodal imaging approach when appropriate. Here, we emphasize the value of a multidisciplinary heart valve team, the endocarditis team, underlining the importance of cardiac and extracardiac imaging experts in playing a key role in informing the diagnosis and management of patients with IE. Illustrative cases, critical appraisal of contemporary data, and conceptual and practical suggestions for clinicians that may help to improve the prognosis of patients with IE are provided in this review article.

Abstract
In the latest update of the European Society of Cardiology (ESC) guidelines for the management of infective endocarditis (IE), imaging is positioned at the centre of the diagnostic work-up so that an early and accurate diagnosis can be reached. Besides echocardiography, contrast-enhanced CT (ce-CT), radiolabelled leucocyte (white blood cell, WBC) SPECT/CT and [18F]FDG PET/CT are included as diagnostic tools in the diagnostic flow chart for IE. Following the clinical guidelines that provided a straightforward message on the role of multimodality imaging, we believe that it is highly relevant to produce specific recommendations on nuclear multimodality imaging in IE and cardiac implantable electronic device infections. In these procedural recommendations we therefore describe in detail the technical and practical aspects of WBC SPECT/CT and [18F]FDG PET/CT, including ce-CT acquisition protocols. We also discuss the advantages and limitations of each procedure, specific pitfalls when interpreting images, and the most important results from the literature, and also provide recommendations on the appropriate use of multimodality imaging.

Abstract
BACKGROUND Pediatric infective endocarditis (IE) has been associated with high morbidity and mortality, mostly related to thromboembolic complications (TEC). The objective of our study was to describe the experience in children with IE and to review the changes over a thirty-year period, regarding origin of IE, incidence of vegetations, TEC and their respective morbidity and mortality rates. METHODS A retrospective chart review of children aged 0-18years with IE defined by the Duke Criteria and admitted to The Hospital for Sick Children, was conducted. Data were divided into three periods (P); P1 (1979-1988); P2 (1989-1998); and P3 (1999-2008). RESULTS The study included 113 patients, median age 7yrs.; females: 46 (41%), congenital heart defects 95 (84%), comparable in all periods. Overall, cardiac vegetations were found in 68/113 patients (60%); large vegetations (≥1cm) in 32 patients (28%). Fourty-five (45/133 [40%]) TEC were documented, 22 patients (20%) developed cerebrovascular events (CVE) and 23 patients (20%) had non-CVE. Patients diagnosed during P3 were older, had more vegetations (p<0.05), and a higher incidence of community acquired-IE (p<0.05). Overall, mortality was 15%, comparable in all periods. Significant risk factors for mortality were vegetations (HR 6.44; 95% CI: 2.07-20.01, p=0.002) and heart failure (HR 28.39; 95% CI: 10.49-76.85, p<0.001). CONCLUSIONS Over the study period, we report a growing incidence of community acquired pediatric IE in older children accompanied by an increasing rate of TEC. Heart failure and vegetations were associated with an increased mortality. These preliminary data need to be confirmed by prospective data.

Abstract
Acute cutaneous necrosis is characterised by a wide range of aetiologies and is associated with significant morbidity and mortality, warranting complex considerations in management. Early recognition is imperative in diagnosis and management of sudden gangrenous changes in the skin. This review discusses major causes of cutaneous necrosis, examines the need for early assessment, and integrates techniques related to diagnosis and management. The literature, available via PubMed, on acute cutaneous necrotic syndromes was reviewed to summarise causes and synthesise appropriate treatment strategies to create a clinician’s guide in the early diagnosis and management of acute cutaneous necrosis. Highlighted in this article are key features associated with common causes of acute cutaneous necrosis: warfarin-induced skin necrosis, heparin-induced skin necrosis, calciphylaxis, pyoderma gangrenosum, embolic phenomena, purpura fulminans, brown recluse spider bite, necrotising fasciitis, ecthyma gangrenosum, antiphospholipid syndrome, hypergammaglobulinemia, and cryoglobulinemia. This review serves to increase recognition of these serious pathologies and complications, allowing for prompt diagnosis and swift limb- or life-saving management.

Abstract
This report will review the role of echocardiography in the diagnosis of cardiac sources of embolism. Embolism of cardiac origin accounts for around 15%–30% of ischemic strokes. The diagnosis of a cardioembolic source of stroke is frequently uncertain and relies on the identification of a potential cardiac source of embolism in the absence of significant autochthonous cerebrovascular occlusive disease. Transthoracic and/or transesophageal echocardiography serves as a cornerstone in the evaluation, diagnosis, and management of these patients. This article reviews potential cardiac sources of embolism and discusses the role of echocardiography in clinical practice. Recommendations for the use of echocardiography in the diagnosis of cardiac sources of embolism are given including major and minor conditions associated with the risk of embolism.

Abstract
Embolism from the heart or the thoracic aorta often leads to clinically significant morbidity and mortality due to transient ischemic attack, stroke or occlusion of peripheral arteries. Transthoracic and transesophageal echocardiography are the key diagnostic modalities for evaluation, diagnosis, and management of stroke, systemic and pulmonary embolism. This document provides comprehensive American Society of Echocardiography guidelines on the use of echocardiography for evaluation of cardiac sources of embolism. It describes general mechanisms of stroke and systemic embolism; the specific role of cardiac and aortic sources in stroke, and systemic and pulmonary embolism; the role of echocardiography in evaluation, diagnosis, and management of cardiac and aortic sources of emboli including the incremental value of contrast and 3D echocardiography; and a brief description of alternative imaging techniques and their role in the evaluation of cardiac sources of emboli. Specific guidelines are provided for each category of embolic sources including the left atrium and left atrial appendage, left ventricle, heart valves, cardiac tumors, and thoracic aorta. In addition, there are recommendation regarding pulmonary embolism, and embolism related to cardiovascular surgery and percutaneous procedures. The guidelines also include a dedicated section on cardiac sources of embolism in pediatric populations.

Abstract
Infectious endocarditis remains both a diagnostic and a treatment challenge. A positive outcome depends on a rapid diagnosis, accurate risk stratification, and a thorough follow-up. Imaging plays a key role in each of these steps and echocardiography remains the cornerstone of the methods in use. The technique of both transthoracic echocardiography and transoesophageal echocardiography has been markedly improved across the last decades and most recently three-dimensional real-time echocardiography has been introduced in the management of endocarditis patients. Echocardiography depicts structural changes and abnormalities in the heart, but it does not uncover the underlying pathophysiological processes at the cellular or molecular level. This problem is addressed with introduction of new molecular imaging methods as (18)F-fluorodesoxyglucose ((18)F-FDG) PET-CT and single photon emission computed tomography fused with conventional CT (SPECT/CT). Of these methods, (18)F-FDG PET-CT carries the best promise for a future role in endocarditis. But there are distinct limitations with both SPECT/CT and (18)F-FDG PET-CT which should not be neglected. MRI and spiral CT are methods primarily used in the search for extra cardial infectious foci. A flowchart for the use of imaging in both left-sided and right-sided endocarditis is suggested.

Abstract
Despite the progress made in diagnosis and treatment of heart valve diseases, the incidence of infective endocarditis (IE) remains constant. It is still associated with high mortality and high rate of embolic complications, including most dangerous one, i.e. stroke. It has a significant impact on further treatment and qualifications for cardiac surgery. In this paper, the authors discuss the epidemiology, mechanisms of stroke and its impact on the qualifications for cardiac surgery. The authors discuss the problem of clinically silent central nervous system embolism in the course of IE and the usefulness of neuroimaging and markers of central nervous system damage in diagnosis of cerebral embolism.

Abstract
The echocardiographic diagnosis of cardiac thrombi, vegetations and tumors as well as the identification of predisposing conditions such as patent foramen ovale, aortic atherosclerosis and other minor causes (e.g., mitral valve prolapse, mitral and aortic valve calcification) have crucial clinical relevance, affecting the choice of surgery and/or of pharmaceutical therapy in the setting of patients presenting embolism. The echocardiographic assessment helps not only for the retrospective diagnosis of sources of embolism but also for the prevention of events in asymptomatic patients. Echocardiography can also distinguish normal variants and artifacts from cardiac masses and tumors. Echocardiographic characterization/typology of cardiac sources of embolism is currently below par when compared with cardiac MRI, the current gold standard. Nevertheless, echocardiography remains the 'first-line' imaging tool, because of its low cost and the possibility to add easily available, functional and structural information at the patient's bedside.

Abstract
Echocardiography plays a key role in the assessment of infective endocarditis (IE). It is useful for the diagnosis of endocarditis, the assessment of the severity of the disease, the prediction of short- and long-term prognosis, the prediction of embolic events, and the follow-up of patients under specific antibiotic therapy. Echocardiography is also useful for the diagnosis and management of the complications of IE, helping the physician in decision-making, particularly when a surgical therapy is considered. Finally, intraoperative echocardiography must be performed in IE to help the surgeon in the assessment and management of patients with IE during surgery. The current 'recommendations for the practice of echocardiography in infective endocarditis' aims to provide both an updated summary concerning the value and limitations of echocardiography in IE, and clear and simple recommendations for the optimal use of both transthoracic and transoesophageal echocardiography in IE.

Abstract
Sub acute left-sided bacterial endocarditis is a serious condition that may be overlooked due to highly variable clinical manifestations. We present the case of a 45-year-old man who presented with complaints of fullness in his abdomen and splenomegaly that referred to the surgery clinic. He underwent diagnostic splenectomy. 3 month after splenectomy endocarditis was diagnosed. We recommend echocardiography in the work up of isolated splenomegaly.

Abstract
Background Infective Endocarditis is associated with a high incidence of embolic events, commonly involving the central nervous system, spleen, kidney, lungs, heart and eyes. Case presentation We report a case of infective endocarditis with late embolization to the L5/S1 region of the spine leading to spondylo-discitis. The disc space infection presented ten days after completion of antibiotic therapy based on blood culture and antibiotic sensitivity. Conclusion This is the first reported case of acute infective spondylo-discitis demonstrated on MR imaging following completion of appropriate antibiotic therapy.

Abstract
Granulicatella elegans is a fastidious organism that is rarely implicated as a cause of infective endocarditis. Here, we describe a patient with mitral valve prolapse who developed G. elegans endocarditis. The organism was isolated from blood cultures and the patient had mitral valvuloplasty and repair, and completed a course of 6 weeks of intravenous antibiotics with no sequela.

Abstract
PURPOSE OF REVIEW Patients with aortic valve infective endocarditis are likely to undergo surgery during the active phase of the disease. The indication and best timing for surgery, however, are still debated. The present review discusses the benefits and risks of early surgery in aortic endocarditis. RECENT FINDINGS Patients with acute aortic regurgitation and clinical or echocardiographic signs of poor tolerance require urgent surgery. Other indications for early surgery include severe perivalvular involvement and high embolic risk. Echocardiography plays an important role in the assessment of embolic risk and helps in choosing the best therapeutic strategy. Several recent studies have identified high-risk subgroups of patients that, without surgery, face poor prognosis. Patients with complicated endocarditis, particularly those with congestive heart failure, will benefit most from surgery. Patients with prosthetic valve endocarditis and cerebral complications represent specific subgroups in which surgical decision is more difficult. SUMMARY Patients with severe aortic leaflet destruction and congestive heart failure, patients with perivalvular extension or uncontrolled infection, and patients with high embolic risk have poor outcome under medical therapy. Early surgery is necessary in all such patients with 'complicated' endocarditis, unless severe comorbidity is present.

Abstract
Infective endocarditis is a rare disease associated with significant morbidity and mortality. In the past decades, there have been significant improvements in the management of infective endocarditis. Complications are frequent and include heart failure, embolic episodes, periannular complications, and central nervous system events. Surgical therapy has been fundamental in the reduction of mortality in complicated cases. This paper is an overview of the main complications of native and prosthetic infective endocarditis and its treatment.

Abstract
Background—
The incidence of embolic events (EE) and death is still high in patients with infective endocarditis (IE), and data about predictors of these 2 major complications are conflicting. Moreover, the exact role of echocardiography in risk stratification is not well defined.
Methods and Results—
In a multicenter prospective European study, including 384 consecutive patients (aged 57±17 years) with definite IE according to Duke University criteria, we tested clinical, microbiological, and echocardiographic data as potential predictors of EE and 1-year mortality. Transesophageal echocardiography was performed in all patients. Embolism occurred before or after IE diagnosis (total-EE) in 131 patients (34.1%) and after initiation of antibiotic therapy (new-EE) in 28 patients (7.3%).
Staphylococcus aureus
and
Streptococcus bovis
were independently associated with total-EE, whereas vegetation length >10 mm and severe vegetation mobility were predictors of new-EE, even after adjustment for
S aureus
and
S bovis
. One-year mortality was 20.6%. In multivariable analysis, independently of the other predictors of death (age, female sex, creatinine serum >2 mg/L, moderate or severe congestive heart failure, and
S aureus
) and comorbidity, vegetation length >15 mm was a predictor of 1-year mortality (adjusted relative risk=1.8; 95% CI, 1.10 to 2.82;
P
=0.02).
Conclusions—
In IE, vegetation length is a strong predictor of new-EE and mortality. In combination with clinical and microbiological findings, echocardiography may identify high-risk patients who will need a more aggressive therapeutic strategy.

Abstract
Echocardiography plays an increasingly important role in diagnosis and management of patients with infective and noninfective endocarditis. Significant changes to diagnostic criteria for endocarditis have occurred, and there are evolving trends associated with an older population presenting with endocarditis, greater numbers of patients with prosthetic heart valves and complex congenital heart disease, and an exponential increase in the numbers of patients eligible for pacing and defibrillator implants. The diagnostic accuracy of echocardiography has been enhanced by developments such as multiplanar transesophageal probes, real-time three-dimensional echocardiography, and intracardiac echocardiography. Standard echocardiography techniques now define the need for and timing of surgical intervention in endocarditis and may help determine the duration of treatment and follow-up after diagnosis.

Abstract
Infective endocarditis (IE) remains a dangerous disease in terms of morbidity and mortality. Valve damage with or without congestive heart failure, paravalvular extension, embolization of vegetation, damage due to immunological involvement and septic shock are the main complications of IE. Embolic events are frequent and life-threatening complications of IE. In previous series, the reported figures of embolic complication vary from 10 to 50%. We describe four cases of patients with IE and peripheral embolization. In this paper, we will briefly discuss the role of echocardiography, infective microorganisms and clinical aspects in the prediction of an embolic event. Therapeutic strategies are discussed.

Abstract
Endocarditis affecting the mitral valve is frequent and is associated with specific features. Mitral prolapse is the most frequent underlying disease and the mechanism of mitral regurgitation secondary to infective endocarditis is frequently complex and multiple. Echocardiography plays a key-role in both the diagnosis, the prognostic assessment and the choice of the best therapeutic option in patients with mitral valve endocarditis. Surgery is frequently necessary, and must be performed early in the course of the disease. Mitral valve repair is the best therapeutic option, when technically possible.
