Project description:AimsCardiac device-related infective endocarditis (CDRIE) is a severe complication of cardiac device (CD) implantation and is usually treated by antibiotic therapy and percutaneous device extraction. Few studies report the management and prognosis of CDRIE in real life. In particular, the rate of device extraction in clinical practice and the management of patients with left heart infective endocarditis (LHIE) and an apparently non-infected CD (LHIE+CDRIE-) are not well described.Methods and resultsWe sought to study in EURO-ENDO, the characteristics, prognosis, and management of 483 patients with a CD included in the European Society of Cardiology EurObservational Research Programme EURO-ENDO registry. Three populations were compared: 280 isolated CDRIE (66.7 ± 14.3 years), 157 patients with LHIE and an apparently non-infected CD (LHIE+CDRIE-) (71.1 ± 13.6), and 46 patients with both LHIE and CDRIE (LHIE+CDRIE+) (70.2 ± 10.1). Echocardiography was not always transoesophageal echography (TOE); it was transthoracic echography (TTE) for isolated CDRIE in 88.4% (TOE = 67.6%), for LHIE+CDRIE- TTE = 93.0% (TOE = 58.6%), and for CDRIE+LHIE+ TTE = 87.0% (TOE = 63.0%). Nuclear imaging was performed in 135 patients (positive for 75.6%). In-hospital mortality was lower in isolated CDRIE 13.2% vs. 22.3% and 30.4% for LHIE+CDRIE- and LHIE+CDRIE+ (P = 0004). Device extraction was performed in 62.1% patients with isolated CDRIE, 10.2% of LHIE+CDRIE- patients, and 45.7% of CDRIE+LHIE+ patients. Device extraction was associated with a better prognosis [hazard ratio 0.59 (0.40-0.87), P = 0.0068] even in the LHIE+CDRIE- group (P = 0.047).ConclusionPrognosis of endocarditis in patients with a CD remains poor, particularly in the presence of an associated LHIE. Although recommended by guidelines, device extraction is not always performed. Device removal was associated with better prognosis, even in the LHIE+CDRIE- group.

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

Project description:BackgroundCulture-negative endocarditis is uncommon, occurring in less than a third of all cases of infective endocarditis (IE). Culture-negative IE related to a cardiac device is an even greater diagnostic challenge due to its insidious presentation, with onset of symptoms ranging between 3 and 12 months after device implantation. Sensitivity of the modified Duke's criteria remains low in culture-negative and cardiac device-related IE (CDRIE) since classical signs and symptoms of IE are often absent. Small vessel vasculitis has been reported as an immune response to IE. Recognizing immunological phenomenon related to IE is of paramount clinical importance, prompting the search for an underlying infection and avoiding the use of immunosuppressive medications which would otherwise result in an adverse outcome.Case summaryAn 81-year-old Caucasian male presented to the ambulatory medical unit with a two-week history of a symmetrical, generalized purpuric rash. He had an indwelling permanent pacemaker following a transcatheter aortic valve implantation for severe aortic stenosis five years ago. Blood tests showed an iron deficiency anaemia, thrombocytopenia and normal renal function, both CRP and ESR were raised at 61 and 30 mm/hr, respectively. Skin biopsy demonstrated small vessel cutaneous vasculitis. Transthoracic echocardiography revealed a mobile mass measuring 0.9 × 1.7 cm, confirmed on transoesophageal echocardiogram as pacing lead endocarditis. Blood cultures were persistently negative. The patient underwent pacemaker lead extraction, following which the vasculitic rash improved.DiscussionBlood cultures in IE are more likely to be negative if there is a prior antibiotic administration or causative micro-organisms with limited proliferation which fail to grow in conventional media conditions. Transesophageal echocardiography (TOE) offers improved sensitivity and diagnostic yield when compared to transthoracic echocardiography (TTE) in patients with a high clinical suspicion of CDRIE. The evidence in the literature describing culture-negative IE associated with small vessel vasculitis is limited. However, it is recognized that cutaneous small vessel vasculitis may be associated with an underlying bacterial infection. IE produces an inflammatory response, resulting in the deposition of circulating immune complexes and cutaneous signs which are included in the modified Duke's criteria to aid diagnosis. Management of CDRIE requires a multi-disciplinary team approach with an 'Endocarditis Team.' Pacemaker lead infection requires transvenous lead extraction if it is a newly implanted lead. Locking stylets, extraction sheaths or snare retrieval are usually required in cases of older implanted leads. Surgical lead extraction remains the gold standard for larger vegetations (>20 mm) or associated valve endocarditis.

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

Project description:Compared with the extensive data on left-sided infective endocarditis (IE), there is much less published information on the features and management of right-sided IE. Right-sided IE accounts for 5% to 10% of all IE cases, and compared with left-sided IE, it is more often associated with intravenous drug use, intracardiac devices, and central venous catheters, all of which has become more prevalent over the past 20 years. In this manuscript on right-sided IE we provide an up-to-date overview on the epidemiology, etiology, microbiology, potential locations of infection in the right heart, diagnosis, imaging, common complications, management, and prognosis. We present updated information on the treatment of pacemaker and device infections, infected fibrin sheaths that appear to be an easily missed source of infection after central line as well as pacemaker removal. We review current data on the AngioVac percutaneous aspiration device, which can obviate the need for surgery in patients with infected pacemaker leads and fibrin sheaths. We also focused on advanced diagnostic modalities, such as positron emission tomography/computed tomography. All of these are supported by specific case examples with detailed echocardiographic imaging from our experience.
