RESUMO

Libman-Sacks endocarditis, characterized by verrucous vegetations formation, is a typical cardiac manifestation of autoimmune diseases such as systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). Although typically mild and asymptomatic, Libman-Sacks endocarditis can lead to serious complications, including thromboembolic events, superimposed bacterial endocarditis, and severe valvular regurgitation and/or stenosis, and valve surgery may be required. Here, we report a case of mitral valve repair for a large Libman-Sacks vegetation in a 29-year-old woman with a history of APS with cerebral infarction. Transesophageal echocardiography (TEE) demonstrated an isolated large mobile vegetation on the atrial side of posterior mitral valve leaflet, with severe mitral regurgitation. Next, we organized a multidisciplinary team meeting to better evaluate the case before performing the surgery. To prevent further thromboembolic events, and due to the insufficiency of the mitral valve, the patient was accepted for mitral valve surgery, and she was discharged uneventfully 10 days after successful surgery. She was managed with long-term anticoagulation medicine after surgery and followed up for 2 years with no complications. The present case showed mitral repair is feasible and effective in young female patients of child-bearing age, and the lesion only localized mitral valve abnormalities caused by Libman-Sacks endocarditis.

RESUMO

BACKGROUND: Echocardiography (echo) is the primary imaging modality for infective endocarditis (IE). However, the recommendations on timing and mode selection for transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) vary across guidelines, which can be confusing for clinical decision makers. In this case, we aim to appraise the quality of recommendations by appraising the quality of various guidelines. METHODS: A search of guidelines containing recommendations for the appropriate use of echo in adult IE patients published in English between 2007 and 2019 was conducted. The APPRAISAL OF GUIDELINES FOR RESEARCH & EVALUATION II (AGREE II) instrument was applied independently by two reviewers to assess the integrated quality of the identified guidelines. The recommendations of concern are extracted from related chapters. RESULTS: A total of 9 guidelines met the criteria, with AGREE II scores ranging from 36 to 79%, and the domain of "stakeholder involvement" received the lowest score. The most contentious issue is whether a follow-up TEE is mandatory in uncomplicated native valve IE with an initial positive TTE. Conflicting recommendations are presented with a low evidence level based on little evidence. CONCLUSIONS: In general, the recommendations proposed in the 9 identified guidelines on the appropriate use of echo are satisfying. The guideline quality score can be taken into account by the clinicians when evaluating the recommendations for clinical decisions. Additional studies with high evidence level should be conducted on the most controversial issues of whether a subsequent TEE is mandatory in uncomplicated native valve IE with an initial positive TTE.

RESUMO

ABSTRACT: Mycobacterium infection remains a leading cause of morbidity and mortality worldwide. Although rare, thoracic cardiovascular complications are associated with devastating consequences if not promptly diagnosed using computed tomography. Intrapulmonary complications include tuberculous aortitis, Rasmussen aneurysms, involvement of bronchial and nonbronchial systemic arteries, and thromboembolic events. Extrapulmonary complications include pericarditis, myocarditis, endocarditis, involvement of coronary arteries, annular-subvalvular left ventricle aneurysms and mediastinal fibrosis. This article will review these complications and their computed tomography features.

RESUMO

NATIONALE: Trichosporon species are widely distributed in nature and are emerging opportunistic human pathogens. Trichosporon infections are associated with superficial cutaneous involvement in immunocompetent individuals to severe systemic disease in immunocompromised patients. Until now, there is no report in infective endocarditis by Trichosporon mucoides confirmed by molecular diagnostics PATIENT CONCERNS:: A 66-year-old man presented with a fever that had occurred for a period of 6 months. He had undergone aortic valve replacement 10 years prior. Transthoracic echocardiography showed vegetations on the prosthetic aortic valve and native mitral valve. T mucoides was detected in the cultures of blood and vegetations. DIAGNOSIS: DNA sequencing using D/D2 region of rRNA and internal transcribed spacer were performed. INTERVENTIONS: Infections were successfully controlled with valve replacement and voriconazole plus liposomal amphotericin B therapy. OUTCOMES: There has been no sign of recurrence for 18-months after treatment completion. LESSONS: This is the first reported case of infective endocarditis due to T mucoides. Clinicians should consider Trichosporon species as causative agents of endocarditis in patients who have undergone cardiac surgery.

RESUMO

BACKGROUND: Emergency or urgent surgery is often required in patients with papillary muscle rupture and active mitral valve infective endocarditis. The aim of this study was to analyze the outcomes of patients with active endocarditis who underwent emergency or urgent mitral valve repair. METHODS: From 2005 to 2014, 154 ischemic mitral regurgitation patients and 41 infective endocarditis patients underwent mitral valve repair in our institution; 23 had emergency operations due to papillary muscle rupture, and 18 with active infective endocarditis underwent urgent surgery. RESULTS: Cardiopulmonary bypass time (141.4 ± 43.3 versus 145.3 ± 46.5 min) and crossclamp time (77.7 ± 34.1 versus 79.2 ± 33.0 min) were similar in the papillary muscle rupture and elective ischemic mitral regurgitation subgroups, and major postoperative complications were comparable. Hospital mortality was 17.4% in the papillary muscle rupture subgroup and 8.4% in the elective ischemic mitral regurgitation subgroup. Cardiopulmonary bypass time (103.6 ± 37.0 versus 75.5 ± 20.8 min) and crossclamp time (61.7 ± 21.2 versus 45.3 ± 18.0 min) were significantly longer in infective endocarditis patients. There were no major complications or hospital deaths. Eight years postoperatively, overall survival was 94.4% and 86.5% in the papillary muscle rupture and elective ischemic mitral regurgitation subgroups, respectively (p = 0.730). Overall survival was 100% in both infective endocarditis subgroups. CONCLUSION: The feasibility and effectiveness of emergency or urgent mitral valve repair in patients with papillary muscle rupture and active infective endocarditis are satisfactory. Early and mid-term outcomes are comparable to those of elective operations.

RESUMO

OBJECTIVES: We retrospectively analyzed our experience of mitral valve repair for native mitral valve endocarditis in a single institution. METHODS: From January 1991 to October 2011, 171 consecutive patients underwent surgery for infective endocarditis. Of these, 147 (86%) had mitral valve repair. At the time of surgery, 98 patients had healed (group A) and 49 had active infective endocarditis (group B). Repair procedures included resection of all infected tissue and thick restricted post-infection tissue, leaflet and annulus reconstruction with treated autologous pericardium, chordal reconstruction with polytetrafluoroethylene sutures, and ring annuloplasty if necessary. Fifty-two (35%) patients required concomitant procedures. The study endpoints were overall survival, freedom from reoperation, and freedom from valve-related events. The median follow-up was 78 months. RESULTS: There was one hospital death (hospital mortality 0.7%). Survival at 10 years was 88.5% ± 3.5% with no significant difference between the two groups (p = 0.052). Early reoperation was required in 4 patients in group B due to persistent infection or procedure failure. Freedom from reoperation at 5 years was 99% ± 1.0% in group A and 89.6 ± 4.0% in group B (p = 0.024). Event-free survival at 10 years was 79.3% ± 4.8% (group A: 83.4% ± 5.9%, group B: 72.6% ± 6.9%, p = 0.010). CONCLUSIONS: Mitral valve repair was highly successful using autologous pericardium, chordal reconstruction, and ring annuloplasty if required. Long-term results were acceptable in terms survival, freedom from reoperation, and event-free survival. Mitral valve repair is recommended for mitral infective endocarditis in most patients.

RESUMO

With its high temporal and spatial resolution and relatively low radiation exposure, positron emission tomography (PET) is increasingly being used in the management of cardiac patients, particularly those with inflammatory cardiomyopathies such as sarcoidosis. This review discusses the role of PET imaging in assessing myocardial viability, inflammatory cardiomyopathies, and endocarditis; describes the different protocols needed to acquire images for specific imaging tests; and examines imaging interpretation for each image dataset-including identification of the mismatch defect in viability imaging, which is associated with significant improvement in LV function after revascularization. We also review the role of fluorodeoxyglucose PET in cardiac sarcoidosis diagnosis, the complementary role of magnetic resonance imaging in inflammatory cardiomyopathy, and the emerging use of cardiac PET in prosthetic valve endocarditis.

RESUMO

Background Infective endocarditis (IE) remains a difficult to diagnose condition associated with high mortality. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has recently emerged as another IE imaging modality, although diagnostic accuracy varies across observational studies and types of IE. This meta-analysis assessed the diagnostic performance of 18F-FDG PET/CT for IE and its subtypes. Methods We searched Pubmed, Cochrane, and Embase from January 1980 to September 2019 for studies reporting both sensitivity and specificity of 18F-FDG PET/CT for IE. Meta-Disc 1.4 was used to pool data for all cases of IE and its subgroups of native valve IE, prosthetic valve IE, and cardiac implantable electronic devices IE. Results We screened 2566 records from the search, assessed 52 full-text articles, and included 26 studies totaling 1358 patients (509 IE cases). Pooled sensitivity and specificity (95% CI, inconsistency I-square statistic) were 0.74 (0.70-0.77, 71.5%) and 0.88 (0.86-0.91, 78.5%) for all cases of endocarditis. Corresponding parameters for native valve IE were sensitivity 0.31 (0.21-0.41, 29.4%) and specificity 0.98 (0.95-0.99, 34.4%); for prosthetic valve IE: sensitivity 0.86 (0.81-0.89, 60.0%) and specificity 0.84 (0.79-0.88, 75.2%); and for cardiac implantable electronic devices IE: sensitivity 0.72 (0.61-0.81, 76.2%) and specificity 0.83 (0.75-0.89, 83.6%). Pooled sensitivities and specificities were higher for the 17 studies since 2015 than the 9 studies published before 2015. Conclusions 18F-FDG PET/CT had high specificity for all IE subtypes; however, sensitivity was markedly lower for native valve IE than prosthetic valve IE and cardiac implantable electronic devices IE. It is, therefore, a useful adjunct modality for assessing endocarditis, especially in the challenging scenarios of prosthetic valve IE and cardiac implantable electronic devices IE, with improving performance over time, related to advances in 18F-FDG PET/CT techniques.

RESUMO

The use of peripherally inserted central catheters (PICCs) has expanded substantially for drug delivery in clinical practice in recent years. However, PICC lines expose patients to potential complications associated with an increasing incidence of infective endocarditis. We herein report a case of a 57-year-old woman who was diagnosed with tricuspid valve endocarditis by echocardiography. The most probable cause was direct injury to the tricuspid valve by the tip of a PICC line with excessive length in the right heart. The vegetation disappeared with conservative treatment after removal of the PICC line. Clinicians must maintain vigilance against any suspected PICC-related infection in febrile patients with a PICC line. For echocardiographers, precise evaluation of the position of the PICC tip and the detection of endocarditis is important to devise the optimal clinical strategy.

RESUMO

INTRODUCTION: Infective endocarditis (IE) is a life-threatening adverse event for patients with congenital heart disease (CHD). Its incidence has changed little over time despite progress in techniques for diagnosis and treatment, and guidelines for prophylaxis. AREAS COVERED: The review sought for key-words: 'congenital heart disease,' 'infective endocarditis,' 'microbial diagnosis,' 'imaging diagnosis,' 'surgical techniques,' 'prognosis,' 'prophylaxis.' Objectives were to investigate epidemiology, novel techniques for imaging and microbial diagnosis, therapeutic management and prognosis, and guidelines for prophylaxis in patients with CHD. The incidence of IE is increasing in adults with CHD. Morbidity caused by a broad clinical spectrum of cardiac and extracardiac episode-related complications is high. Surgical management is increasingly required in the early phase of the disease. Despite new techniques for diagnosis and microbiological therapy, mortality rate is still up to 10-20%. EXPERT OPINION: IE has increased in the growing cohort of adults with complex heart disease, living with residual cardiac lesions and prosthetic materials. Diagnosis is challenging for complex heart defects. Pet-scan technique can provide beneficial information to locate intracardiac lesions and embolic foci. Identification of the microbiological agents is improving. Innovative surgical techniques aim to avoid prosthetic material. Guidelines for prophylaxis currently emphasize oral and skin daily hygiene.

RESUMO

Infective endocarditis (IE) is a serious condition leading to heart failure, persistent sepsis. The management of IE involving valve is mainly excision of the infected valve and replacement with a heart valve; which are also at the risk of prosthetic valve endocarditis. Hence repair of the valve with autologous pericardium is much more physiological. We had a 20-year-old male presented with features of heart failure and high-grade fever not responding to optimum medical management. Two-dimensional echocardiogram revealed vegetation on pulmonary valve cusps with the erosion of the left and right cusps. Neo cusps with autologous pericardium offered good hemodynamics with trivial regurgitation. The patient is doing well with normal pulmonary valve function 3 months after surgery. This technique is reliable, economic, and easily reproducible.

RESUMO

Coronavirus disease 2019 (COVID-19) has emerged as a pandemic and public health crisis across the world. With its high infectivity and rapid spread, the severity of the disease is escalating in certain populations, especially in patients with pre-existing cardiovascular disease. In developing countries, infective endocarditis remains a problem in patients with rheumatic heart disease. We report the case of a patient with a diagnosis of infective endocarditis concomitant with COVID-19, including the diagnosis, management, and main outcomes.

RESUMO

BACKGROUND: Healthcare-associated infective endocarditis (HAIE) has become increasingly recognized worldwide because the underlying patient conditions are completely different from those of community-acquired infective endocarditis (CIE). However, data on HAIE in the Japanese population is lacking. We sought to clarify the patient characteristics and prognosis of HAIE in a Japanese population.Methods and Results:A retrospective study was conducted in 158 patients who were diagnosed with infective endocarditis, 53 of whom (33.5%) were classified as HAIE. Compared with patients with CIE, those with HAIE were older (median age 72 vs. 61 years; P=0.0002) and received surgical treatment less frequently (41.5% vs. 62.9%; P=0.01). Regarding causative microorganisms, staphylococci,including methicillin-resistant pathogens, were more common in patients with HAIE (32.1% vs. 14.3%; P=0.01). Patients with HAIE had higher in-hospital mortality (32.1% vs. 4.8%; P<0.0001) and Kaplan-Meier analysis showed worse prognosis for patients with HAIE than CIE (P<0.0001, log-rank test). On multivariate Cox analysis, HAIE (hazard ratio 3.26; 95% confidence interval 1.49-7.14), age ≥60 years, surgical treatment, stroke, and heart failure were independently associated with mortality. CONCLUSIONS: HAIE has different clinical characteristics and causative microorganisms, as well as worse prognosis, than CIE. Preventive strategies, and the prompt and appropriate identification of HAIE may improve the outcome of infective endocarditis.

RESUMO

INTRODUCTION: The Ross procedure plays a pivotal part in both congenital and acquired diseases of the aortic valve, especially in young patients. The advantages of this procedure are widely known; however, long-term studies have shown dilation of the pulmonary autograft (PA) in up to 20% of patients in the second decade postoperatively. METHODS: Three cases (ages 38, 51, and 53) who underwent the Ross procedure 23 years ago for bicuspid valves and endocarditis. Cases were followed-up with echocardiogram and computed tomography scan with three-dimensional reconstructions. RESULTS: The PA showed normal function with favorable geometry alongside the thoracic aorta, while the pulmonary homograft preserved its function with a low degree of calcification. The mean annual expansion of the autograft was only 0.15, 0.30, and 0.40 mm with no pathological dilation after 20 years DISCUSSION: Ross operation provides excellent hemodynamic results while avoiding long-term anticoagulation and might constitute a valid adjunct in selected categories such as young or endocarditis patients.

RESUMO

Infective endocarditis (IE) is a serious and potentially lethal condition. The diagnostic capacity of the modified Duke criteria is high for native valves, but it declines in the case of EI of prosthetic valves or EI associated with devices. Echocardiography and microbiological findings are essential for diagnosis but may be insufficient in this group of patients. Our objective was to evaluate the usefulness of positron emission tomography and fusion with computed tomography (PET / CT) in patients with suspected IE, carriers of prosthetic valves or intracardiac devices; 32 patients were studied, who underwent PET / CT with 18F-Fluorine deoxyglucose (18F-FDG). Those with intense focal and/or heterogeneous uptake with a Standard Uptake Value SUV) cut-off point greater than or equal to 3.7 were considered suggestive of infection. The initial diagnoses according to the modified Duke criteria were compared with the final diagnosis established by the Institutional Endocarditis Unit. The addition of PET / CT to these criteria, provided a conclusive diagnosis in 22 of the 32 initial cases reclassifying 11 cases in definitive EI; another 5 cases were negative for that diagnosis. EI continues to be a serious clinical problem. In those cases where the Duke criteria are not sufficient to establish the diagnosis and clinical suspicion persists, PET / CT can be a useful complementary tool to increase the diagnostic sensitivity.

RESUMO

Posterior reversible encephalopathy (PRES) is a clinical syndrome characterized by headaches, seizures, cortical blindness, and altered mental status up to coma and by a radiological syndrome defined by edematous alteration on Magnetic Resonance Imaging (MRI)-Scans of the white matter. In the following, we present the case of a 73 years old post-operative patient with PRES in the context of hypertension and endocarditis with E. coli. The initial presentation included a series of seizures, sopor, and cortical blindness. In MRI-Scans a marked cerebral edema could be identified. After successful treatment of underlying conditions, the patient has made a good recovery. However, homonymous hemianopsia towards right due to laminar necrosis in the left occipital lobe remained as a residuum.

RESUMO

La endocarditis infecciosa es infrecuente pero potencialmente mortal. Las presentaciones atípicas retrasan el diagnóstico. El compromiso neurológico es habitual en la endocarditis de la válvula mitral, aunque infrecuente en la endocarditis de la válvula tricúspide. Si bien se han informado algunos casos e el del lado derecho con síntomas neurológicos en adultos, en la bibliografía no se ha descripto en niños. Se presenta una niña de 9 años con comunicación interventricular (CIV) congénita con fiebre, cefalea y rigidez de nuca. Sus síntomas clínicos y los hallazgos en el líquido cefalorraquídeo respaldaron el diagnóstico de meningitis aséptica. El día 3 del tratamiento con ceftriaxona, se resolvieron los síntomas; tras nueve días, reingresó con fiebre y rigidez de nuca. Un ecocardiograma mostró endocarditis de la válvula tricúspide. Recibió tratamiento antibiótico durante 6 semanas. Se realizó una cirugía cardíaca para la CIV y la insuficiencia de la válvula tricúspide.


Infective endocarditis (IE) is a rare but a potentially life-threatening infectious disease. Atypical presentations cause delays in the diagnosis. Neurological involvement such as meningitis or meningismus, are especially common in mitral valve endocarditis, but unusual in tricuspid valve endocarditis. Although few cases of right-sided IE have been reported with neurological symptoms in adults, children have not been described in literature. A nine-year-old girl with congenital ventricular septal defect (VSD) was admitted with fever, headache and neck stiffness. Her clinical symptoms and cerebrospinal fluid findings supported the aseptic meningitis. On ceftriaxone therapy day 3, her complaints were resolved; nine days later she was admitted with fever and neck stiffness again. Further investigation for fever source with echocardiogram revealed a tricuspid valve endocarditis. Antibiotic therapy was completed after 6 weeks. Cardiac surgery was performed for VSD and tricuspid valvular insufficiency.

RESUMO

The role of two dimensional (2D) echocardiography (ECHO) for the diagnosis and clinical decision making in infective endocarditis (IE) has been extensively studied and described in the medical literature. Some reports have demonstrated the incremental value of three dimensional (3D) transesophageal (TE) ECHO in the setting of IE. However, a systematic review focusing on the role of 3D imaging is lacking. In this manuscript, we examine the role of 3D TE ECHO in the diagnosis of IE. IE is a challenging disease in which 2D transthoracic (TT) and TE ECHO have complementary roles and are unequivocally the mainstay of diagnostic imaging. Still, 2D imaging has important limitations. Technological advances in 3D imaging allow for the reconstruction of real-time anatomical images of cardiac structure and function. 3D imaging has emerged as a diagnostic technique that overcame some of the limitations of 2D ECHO. Currently, both transthoracic and transesophageal echocardiography transducers are able to generate 3D images. However, 3D TE ECHO provides images of a higher quality in comparison to 3D TT ECHO, and is the best echocardiographic modality able to allow for a detailed anatomical imaging. 3D TE ECHO may represent the key adjunctive echocardiographic technique being able to positively impact on IE-related surgical planning and intervention and to facilitate the interaction between the surgeon and the imaging specialist. Importantly, 3D TE ECHO is not the recommended initial modality of choice for the diagnosis of IE; however, in highly specialized centers, it has become an important complementary technique when advanced surgical planning is required. Furthermore, anatomical imaging has become the link between the different techniques that play a role in IE imaging. In fact, both computed tomography and magnetic resonance allow three dimensional reconstruction. An important future goal should allow for the fusion among various imaging modalities. Our review highlights the role of 3D TE ECHO in IE imaging and emphasize where it offers incremental value.
