ABSTRACT
INTRODUCTION: Infective endocarditis (IE) has a high mortality rate in developing countries including Malaysia. This clinical audit aims to identify the shortcomings in the diagnosis and management of IE patients in a local tertiary centre to implement changes for improvement. MATERIALS AND METHODS: This retrospective audit had two cycles - the first includes all IE patients in Sarawak Heart Centre, Malaysia from January 2020 to December 2022 with different parameters (blood culture, echocardiogram, the appropriateness of antibiotics and surgery) assessed against Malaysian Clinical Practice Guideline (CPG); and reaudit from July 2023 to December 2023. Interventions before re-audit include presentation at different hospital levels and continuing medical education. RESULTS: Fifty patients were recruited (37 in the first cycle, 13 in the second cycle). The median age was 48.5 years with male predominance. Valve prosthesis (12.0%) and rheumatic heart disease (10.0%) were the commonest predisposing factors. Native mitral (44.0%) and aortic valves (28.0%) were most commonly involved. Twenty-eight (56.0%) patients were culture-positive. In the first cycle, most parameters (culture technique 0.0%, vegetation measured 54.1%, empirical 5.4%, culture-guided 29.7% antibiotics therapy, indicated surgery 0.0%) did not achieve the expected standard except timeliness of echocardiograms and blood culture incubation period. After initial interventions, all parameters showed statistically significant improvement (culture technique p<0.001, echocardiography p<0.001, empirical p<0.001, culture-guided p=0.021, surgery p<0.001) during the re-audit. CONCLUSION: Compliance with clinical practice guidelines (CPG) on IE management was suboptimal during the first audit but improved after interventions. Hence, regular continuing medical education (CME) is essential, and a written hospital protocol may be useful. Regular audits alongside multidisciplinary teamwork are crucial efforts.

Fungi rarely cause infective endocarditis but when they do, they are often associated with poor outcomes. Candida tropicalis accounts for only 10% of Candida endocarditis cases. A case of a 30-year-old male with a history of intravenous drug abuse was reported to the emergency department in August, 2021 with right-sided leg pain and fever for 3 days. A trans-thoracic echocardiogram showed a vegetation on the aortic valve and a computed tomography angiogram showed complete nonopacification of the right-sided common iliac artery and the superficial femoral artery just distal to its branching of the right profunda femoris artery. An emergent right iliofemoral embolectomy was done. Candida tropicalis was isolated from tissue and blood cultures. The patient was successfully treated with aortic valve replacement and intravenous caspofungin. The other reported cases of Candida tropicalis were reviewed and findings were compared with those reported in patients with Candida albicans and Candida parapsilosis endocarditis.

The Duke Criteria have shaped the way infectious endocarditis (IE) is diagnosed in the last 30 years. This study aims to evaluate their current validity and importance in the diagnostic of IE. A retrospective cohort study was conducted on 163 consecutive patients who presented at the University Hospital in Ulm (Germany) with clinical suspicion of IE between 2009 and 2019. With patients' medical records we differentiated between definitive endocarditis (DIE), possible endocarditis (PIE) and rejected endocarditis (RIE) and assessed the validity of the Duke Criteria in comparison to the final discharge diagnosis. We then tried to identify new potential parameters as an addition to the current valid Duke Criteria. The validity of the Duke Criteria improves with the length of hospitalization (especially cardiac imaging criterion, RIE 33.3%, PIE 31.6% and DIE 41.9%, p = 0.622 at admission and RIE 53.3%, PIE 68.4%, DIE 92.2%, p < 0.001 at discharge). At admission, overall sensitivity and specificity were respectively 29.5 and 91.2% in the DIE group. At discharge, sensitivity in the DIE group rose to 77.5% and specificity decreased to 79.4%. Of all screened metrics, microhematuria (p = 0.124), leukocyturia, (p = 0.075), younger age (p = 0.042) and the lack of rheumatoid disease (p = 0.011) showed a difference in incidence (p < 0.2) when comparing DIE and RIE group. In multivariate regression only microhematuria qualified as a potential sixth minor criterion at admission. Even with the latest technological breakthroughs our findings suggest that the Duke Criteria continue to hold value in the accurate assessment of IE. Future efforts must shorten the time until diagnosis.

OBJECTIVE: Despite advancements in surgical techniques, operations for infective endocarditis (IE) remain associated with relatively high mortality. The aim of this study was to develop a nomogram model to predict the early postoperative mortality in patients undergoing cardiac surgery for infective endocarditis based on the preoperative clinical features. METHODS: We retrospectively analyzed the clinical data of 357 patients with IE who underwent surgeries at our center between January 2007 and June 2023. Independent risk factors for early postoperative mortality were identified using univariate and multivariate logistic regression models. Based on these factors, a predictive model was developed and presented in a nomogram. The performance of the nomogram was evaluated through the receiver operating characteristic (ROC) curve, calibration plot, and decision curve analysis (DCA). Internal validation was performed utilizing the bootstrapping method. RESULTS: The nomogram included nine predictors: age, stroke, pulmonary embolism, albumin level, cardiac function class IV, antibotic use <4weeks, vegetation size ≥1.5 cm, perivalvular abscess and preoperative dialysis. The area under the ROC curve (AUC) of the model was 0.88 (95%CI:0.80-0.96). The calibration plot indicated strong prediction consistency of the nomogram with satisfactory Hosmer-Lemeshow test results (χ2 = 13.490, p = 0.142). Decision curve analysis indicated that the nomogram model provided greater clinical net benefits compared to "operate-all" or "operate-none" strategies. CONCLUSIONS: The innovative nomogram model offers cardiovascular surgeons a tool to predict the risk of early postoperative mortality in patients undergoing IE operations. This model can serve as a valuable reference for preoperative decision-making and can enhance the clinical outcomes of IE patients.

The geriatric failure to thrive, a controversial French concept not present in the international literature, was first characterized by Jean Carrié in 1956. It is described as a process of aging and physical and psychological decline associated with advanced age, manifesting as a pronounced overall deterioration. In this case report, we present the case of an 88-year-old patient, admitted to a general medicine service for geriatric failure to thrive, whose management eventually leads to the diagnosis of endocarditis with digestive cancer complicated by a characterized depressive episode. This case prompts us to consider the geriatric failure to thrive with extreme caution and challenges the legitimacy of such a diagnosis in the context of an aging population and the progress of medical sciences.

First described more than 350 years ago, infective endocarditis represents a global health concern characterised by infections affecting the native or prosthetic heart valves, the mural endocardium, a septal defect, or an indwelling cardiac device. Over recent decades, shifts in causation and epidemiology have been observed. Echocardiography remains pivotal in the diagnosis of infective endocarditis, with alternative imaging modalities gaining significance. Multidisciplinary management requiring expertise of cardiologists, cardiovascular surgeons, infectious disease specialists, microbiologists, radiologists and neurologists, is imperative. Current recommendations for clinical management often rely on observational studies, given the limited number of well conducted randomised controlled trials studying infective endocarditis due to the rarity of the disease. In this Seminar, we provide a comprehensive overview of optimal clinical practices in infective endocarditis, highlighting key aspects of pathophysiology, pathogens, diagnosis, management, prevention, and multidisciplinary approaches, providing updates on recent research findings and addressing remaining controversies in diagnostic accuracy, prevention strategies, and optimal treatment.

INTRODUCTION: Infective endocarditis is a rare but potentially severe disease, associated with significant morbidity and mortality. Our study aims to describe the epidemiology and management aspects of endocarditis in northern Morocco and compare it with international management guidelines. MATERIALS AND METHODS: This is a retrospective study involving all patients hospitalized in the cardiology department of the University Hospital of Tangier for infective endocarditis over a period of 4 years and 7 months, from May 2019 to February 2024. RESULTS: Eighty patients were hospitalized for IE during the study period. The average age of the patients was 46 years, with an even sex ratio. IE concerned native valves in 77% of cases, mechanical prostheses in 19% of cases, and on bio prostheses in 4%. The average diagnostic delay was 25 days. Blood cultures were negative in 59% of cases. The predominant infective microorganism was the bacteria Staphylococcus (65.6%). Imaging results showed vegetations in 76.3% of cases, predominantly on the mitral valve (39.3%), followed by the aortic valve (21.3%). The main complications included heart failure (51.2%), peripheral arterial embolisms (22.5%) and splenic infarction (17.5%). Management wise, the most commonly used antibiotic therapy was a combination of ceftriaxone and gentamicin. Clinical and biological improvement was observed in 70% of cases, with a mortality rate of 12.5%. Twelve patients underwent surgery (15%). Urgent surgery was indicated in 66,7% of the operated patients. CONCLUSION: Our study highlights the challenges in managing infective endocarditis in northern Morocco. The prognosis of infective endocarditis can be improved through multidisciplinary management within the implementation of an Endocarditis Team.

INFECTIOUS ENDOCARDITIS: STRATEGY FOR DIAGNOSIS. The diagnosis of infective endocarditis is often difficult because the clinical presentations are very heterogeneous. Epidemiology has evolved with more acute forms, different microorganisms, and an increase in prevalence in patients with cardiac prosthetic or electronic devices. Diagnosis is based on a clinical suspicion, associated with microbiological data and imaging evidence of lesions of the endocardium. Echocardiography plays a key role, but advanced imaging techniques provide additional information. The 2023 European Society of cardiology (ESC) recommendations like those of 2015 confirmed the essential role of multimodal imaging, integrating lesions highlighted by any imaging technique as major criteria. The diagnostic criteria have thus been modified to consider new epidemiological and imaging data. Different diagnostic strategy algorithms are proposed depending on whether the patient has prosthetic material or not. The endocarditis team is the keystone in this diagnostic approach to improve patient management.
ENDOCARDITES INFECTIEUSES: DÉMARCHE DIAGNOSTIQUE. Le diagnostic d'endocardite infectieuse est souvent difficile, car les présentations cliniques sont hétérogènes. L'épidémiologie a évolué avec des formes plus aiguës, des micro-organismes différents et avec l'augmentation de la prévalence chez les patients porteurs de matériel intracardiaque. Le diagnostic repose sur une suspicion clinique supportée par des données microbiologiques et la mise en évidence de lésions de l'endocarde à l'imagerie. L'échocardiographie joue un rôle clé, mais les techniques avancées d'imagerie permettent d'améliorer les performances diagnostiques. Les recommandations de l'European Society of Cardiology (ESC) 2023, comme celles de 2015, ont confirmé le rôle essentiel de l'imagerie multimodale, intégrant comme critères majeurs les lésions mises en évidence par toute technique d'imagerie. Les critères diagnostiques ont été ainsi modifiés pour prendre en compte les nouvelles données épidémiologiques et d'imagerie. Différents algorithmes de stratégie diagnostique sont proposés selon que le patient est porteur de matériel prothétique ou non. L'équipe multidisciplinaire d'endocardite est la clé de voûte dans cette démarche diagnostique pour améliorer la gestion des patients.

TREATMENT OF INFECTIVE ENDOCARDITIS. Patients with infective endocarditis (IE) are taken care for by multidisciplinary teams. The treatment consists of antibiotic therapy initiated early, adapted to the responsible germ and prolonged, associated with surgical treatment when there is an indication for surgery. A parenteral antibiotic therapy is initiated in hospital for a period of at least two weeks. Depending on evolution of the patients, outpatient antibiotic treatment may be considered, and oral antibiotics may be proposed in stable patients when IE is caused by the most frequent germs. The surgical treatment of IE consists of total excision of the infected tissues and aims to restore the integrity of valvular functions. Conservative surgical treatment is performed, when possible, otherwise valve replacement is the alternative. The recognition of surgical indications (heart failure, uncontrolled infection, and prevention of embolic risk) is essential to improve the prognosis.

EUROPEAN REGISTRY OF INFECTIOUS ENDOCARDITIS. The EURO-ENDO registry was initiated in 2018. Its objectives were to assess the epidemiological, clinical, bacteriological, and prognostic features of infective endocarditis. Initially only European, it rapidly become a world registry including more than 3000 patients worldwide. EURO-ENDO confirms the drastic change in the profile of patients suffering from infective endocarditis, the important improvements in their management, but their persisting high mortality. EURO-ENDO also underlines the value of an early diagnosis of this disease as well as its management in highly specialized centers, with an experienced medical and surgical team.
REGISTRE EUROPÉEN DES ENDOCARDITES INFECTIEUSES. Le registre EURO-ENDO a été créé en 2018 pour préciser les caractéristiques épidémiologiques, cliniques, bactériologiques, diagnostiques et pronostiques de l'endocardite infectieuse. Initialement européen, il est en fait devenu un registre mondial incluant plus de 3 000 patients à travers le monde. Il confirme le changement radical du profil des patients atteints d'endocardite infectieuse, les grands progrès diagnostiques et thérapeutiques mais également la persistance d'une mortalité élevée chez des patients de plus en plus âgés et polypathologiques. Il souligne l'intérêt d'un diagnostic précoce permettant une prise en charge immédiate par une équipe médico-chirurgicale habituée à traiter cette pathologie complexe.

COMPLICATIONS OF INFECTIVE ENDOCARDITIS. The high in-hospital mortality of patients with infective endocarditis (about 20%) is mainly due to its complications. These complications are essentially of cardiac, neurological, and infectious origin. Rapid diagnosis and early antibiotic treatment are of paramount importance and allow drastic reduction of the frequency and severity of such complications. Discussion with all physicians caring for the patients with infective endocarditis in an "endocarditis team" setting is a mandatory step in management optimization and outcome improvement. This "endocarditis team" approach allows faster identification of patients at high risk of acute heart failure and/or cerebral embolism, and selection of those who might benefit from urgent valvular surgery. Factors associated with high embolic risk are the size and mobility of vegetation, mitral valve endocarditis, and infection with Staphylococcus aureus. When neurological complications occur, there is a risk that these may be worsened by the valvular surgery if there is a hemorrhagic component. This risk needs to be careful weighed in a team approach before sending patients to surgery. Persistent sepsis after effective antibiotic treatments prompts to local extension of the disease or to embolic extra cardiac secondary infectious localization.
COMPLICATIONS DE L'ENDOCARDITE INFECTIEUSE. Les complications de l'endocardite infectieuse (EI) sont à l'origine d'une mortalité hospitalière élevée d'environ 20 %. Elles sont essentiellement cardiaques, neurologiques et septiques. Un diagnostic rapide et une antibiothérapie précoce sont essentiels, car ils permettent de réduire la fréquence et la sévérité de ces complications. Une discussion collégiale au sein de l'équipe pluridisciplinaire (endocarditis team) est indispensable pour optimiser la prise en charge et améliorer le pronostic. Elle permet notamment d'identifier rapidement les patients à haut risque d'insuffisance cardiaque aiguë et/ou d'embolie cérébrale et de sélectionner les patients nécessitant une chirurgie valvulaire urgente. Les facteurs prédictifs d'un haut risque embolique sont la taille et la mobilité de la végétation, sa localisation sur la valve mitrale et l'EI à Staphylococcus aureus. La survenue d'une complication neurologique nécessite une évaluation rigoureuse compte tenu des risques d'aggravation de la lésion par la chirurgie valvulaire en présence d'une composante hémorragique. Un sepsis persistant sous traitement antibiotique doit faire rechercher une extension locale de l'endocardite ou des foyers emboliques extracardiaques.

INTRODUCTION: Current risk score models for predicting mortality in infective endocarditis (IE) include data often unavailable in registries, limiting their use for confounding adjustment in population-based research. METHODS: This study assessed the Danish Comorbidity Index for Acute Myocardial Infarction (DANCAMI) for its ability to predict 30-day, 1-year, and 5-year mortality in IE patients, compared to the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI). The study included all adult Danish patients with first-time IE from 1995 to 2021. The area under the receiver operating characteristic curve (AUC) was estimated using logistic regression to measure discriminatory performance for all-cause and cardiovascular mortality at the specified time intervals. A baseline model included age and sex, while extended models incorporated continuous comorbidity scores. RESULTS: We identified 8966 patients with IE. Mortality rates were 12% at 30 days, 26% at 1 year, and 36% at 5 years. For all-cause mortality, AUCs for the baseline versus DANCAMI models were 0.64 vs. 0.69 at 30 days, 0.66 vs. 0.73 at 1 year, and 0.72 vs. 0.79 at 5 years. For cardiovascular mortality, AUCs for baseline versus DANCAMI models were 0.67 vs. 0.69 at 30 days, 0.67 vs. 0.69 at 1 year, and 0.70 vs. 0.71 at 5 years. CCI and ECI demonstrated comparable AUCs to the DANCAMI model. CONCLUSION: DANCAMI improved discrimination of short- and long-term mortality in IE patients and may be used for confounder adjustment similarly to CCI and ECI.

BACKGROUND Histoplasma capsulatum is prevalent in the mid-eastern United States and is an environmental fungus that causes human infection by the inhalation of its spores. It is commonly associated with areas containing large amounts of bird excrement and can survive for years in the soil. Only 1% of infected individuals develop disseminated histoplasmosis or Histoplasma endocarditis. CASE REPORT A 61-year-old man with atrial fibrillation had 8 months of fatigue, low-grade fevers, night sweats, and unexplained weight loss presented to the Emergency Department. He worked and lived in Central Florida and although he raised cattle, he denied exposure to birds or bats with regularity. A transesophageal echocardiogram confirmed a sessile echo density on the atrial surface of the mitral valve. His microbial Karius cell-free DNA test from his blood sample was positive for Histoplasma capsulatum, and he was immediately given intravenous liposomal amphotericin for 2 weeks. A tissue valve was used to successfully replace his mitral valve along with a coronary artery bypass and a maze procedure for his persistent atrial fibrillation and atrial flutter. The diagnosis of mitral valve endocarditis from disseminated histoplasmosis was confirmed by pathological analysis, and he was sent home on long-term itraconazole maintenance treatment. CONCLUSIONS Surgical intervention in combination with anti-fungal medication can be a lifesaving intervention for disseminated histoplasmosis. A thorough history is particularly important when evaluating a patient with an unknown infectious source, especially assessing for risk factors, including exposure to environmental factors, workplace, and animals.

INTRODUCTION: Congenital heart diseases (CHD) with abnormal turbulent blood flow are associated with the highest risk of infective endocarditis (IE). Despite advancement in diagnostics and treatment, the mortality rate of IE remains high due the life-threatening complications. Our study aims to assess the incidence and mortality rates of IE and predictive factors for mortality among adults CHD (ACHD). METHODS: A systematic literature search was conducted on PubMed, SCOPUS, and Ovid SP to retrieve relevant studies. The pooled estimates and predictors of mortality were calculated using the random-effects generic inverse variance method using R programming. RESULTS: 12 studies involving 3738 ACHD patients were included in this meta-analysis. The overall incidence of IE in ACHD was 1.26 per 1000 patient-years (95% CI 0.55-1.96). 60% (95% CI 46-72%) of patients had surgical management for IE. The mortality rate of IE was 9% (95% CI 7-12%). The predictors of mortality were conservative management (OR: 5.07, 95% CI: 4.63-5.57), renal dysfunction (OR: 4.15, 95% CI: 2.92-5.88), cerebral complications (OR: 3.59, 95% CI: 1.78-7.23), abscesses/valve complications (OR: 2.67, 95% CI: 1.71-4.16), Staphylococcus aureus infection (OR: 2.32, 95% CI: 1.33-4.06), emboli (OR: 2.03, 95% CI: 1.47-2.79), body mass index (OR: 1.10, 95% CI: 1.01-1.21), age (OR: 1.02, 95% CI: 1.00-1.04), and previous IE (OR: 1.02, 95% CI: 1.00-1.04). CONCLUSION: The mortality rate of IE in ACHD is low. However, conservative management is associated with the highest risk of mortality.

BACKGROUND: Streptococci are a common cause of infective endocarditis (IE). We aimed to evaluate the performance of the HANDOC score to identify patients at high risk for IE and the Duke clinical criteria of the European Society of Cardiology (ESC; 2015 and 2023 versions) and the 2023 version from the International Society of Cardiovascular Infectious Diseases (ISCVID) in diagnosing IE among patients with streptococcal bacteremia. METHODS: This retrospective study included adult patients with streptococcal bacteremia hospitalized at Lausanne University Hospital. Episodes were classified as IE by the Endocarditis Team. A HANDOC score >2 classified patients as high risk for IE. RESULTS: Among 851 episodes with streptococcal bacteremia, IE was diagnosed in 171 episodes (20%). Among 607 episodes with non-ß-hemolytic streptococci, 213 (35%) had HANDOC scores >2 points; 132 (22%) had IE. The sensitivity of the HANDOC score to identify episodes at high risk for IE was 95% (95% confidence interval [CI], 90%-98%), the specificity 82% (95% CI, 78%-85%), and the negative predictive value (NPV) 98% (95% CI, 96%-99%). 2015 Duke-ESC, 2023 Duke-ISCVID, and 2023 Duke-ESC clinical criteria classified 114 (13%), 145 (17%), and 126 (15%) episodes as definite IE, respectively. Sensitivity (95% CI) for the 2015 Duke-ESC, 2023 Duke-ISCVID, and 2023 Duke-ESC clinical criteria was calculated at 65% (57%-72%), 81% (74%-86%), and 73% (65%-79%), respectively, with specificity (95% CI) at 100% (98%-100%), 99% (98%-100%), and 99% (98%-100%), respectively. CONCLUSIONS: The HANDOC score showed an excellent NPV to identify episodes at high risk for IE. Among the different versions of the Duke criteria, the 2023 Duke-ISCVID version fared better for the diagnosis of IE among streptococcal bacteremia.

A 6-month-old male intact miniature Australian Shepherd presented for surgical consultation for a previously diagnosed patent ductus arteriosus. Echocardiogram revealed a patent ductus arteriosus and a hyperechoic oscillating lesion within the main pulmonary artery. Blood cultures and eventual post-mortem examination revealed Candida tropicalis endocarditis. This case report highlights a rare case of fungal endocarditis with both echocardiographic and post-mortem findings.
