Clinical impact of capsulectomy during cardiac implantable electronic device generator replacement: a prospective randomized trial. J Interv Card Electrophysiol 2024:10.1007/s10840-024-01765-3. [PMID: 38374300 DOI: 10.1007/s10840-024-01765-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Accepted: 01/30/2024] [Indexed: 02/21/2024]
Abstract
BACKGROUND The avascular capsule around the generator of the cardiac implantable electronic device (CIED) could be susceptible to bacterial colonization and source of infection. Capsulectomy during CIED generator replacement may be beneficial in preventing device infection, but there is a lack of evidence. METHODS This prospective randomized trial, conducted from December 2013 to December 2019, included 195 patients divided equally into two groups. In the intervention group (n = 97), capsule removal was performed on the floor of the pocket, while it was not performed in the control group (n = 98). In both groups, swab culture was performed in the pocket. The primary outcome was the occurrence of device infection requiring pocket revision. RESULTS A total of 195 patients were included (mean age 70.2 ± 13.6 years, 55.4% women), with an average follow-up period of 54.3 ± 28.9 months. Among 182 patients undergoing microbiological cultures of pockets, 19 (10.4%) were confirmed positive, and Staphylococcus species were identified most frequently. The primary outcome occurred in 4 (2.1%), and there was no significant difference between the two groups (3.1% vs. 1.0%, p = 0.606). Hematoma has occurred in 10 patients (3.1% vs. 7.1%, p = 0.338), one of them required wound revision. In multivariable analysis, the occurrence of hematoma was the only independent risk factor associated with device infection (HR 13.6, 95% CI 1.02-181.15, p = 0.048). CONCLUSIONS In this long-term prospective study, capsulectomy during the replacement of the generator did not reduce the incidence of device infection. There was no association between bacterial colonization in the capsule around the generator and CIED infection.

Anti-biofilm activity of antibiotic-loaded Hylomate®. IJC HEART & VASCULATURE 2021; 34:100801. [PMID: 34159252 PMCID: PMC8203729 DOI: 10.1016/j.ijcha.2021.100801] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 05/13/2021] [Accepted: 05/15/2021] [Indexed: 11/30/2022]
Abstract
Introduction Antibiotic envelopes are being developed for cardiac implantable electronic device (CIED) wrapping to reduce the risk of infections. Methods Fifteen CIED infection-associated bacterial isolates of Staphylococcus aureus, Staphylococcus epidermidis and Cutibacterium acnes were used to assess in vitro biofilm formation on Hylomate® compared to titanium, silicone and polyurethane coupons pre-treated with vancomycin (400 µg/ml), bacitracin (1000 U/ml) or a combination of rifampin (80 µg/ml) plus minocycline (50 µg/ml). Scanning electron microscopy (SEM) was performed to visualize bacteria on Hylomate®. Results There was significantly less (p < 0.05) S. aureus and S. epidermidis on Hylomate® pre-treated with vancomycin, bacitracin or rifampin plus minocycline after 24 h of incubation (≤1.00 log10 CFU/cm2) compared with titanium, silicone or polyurethane pre-treated with vancomycin, bacitracin or rifampin plus minocycline. C. acnes biofilms were not detected (≤1.00 log10 CFU/cm2) on pre-treated Hylomate® coupons. Conclusions This study showed that Hylomate® coupons pre-treated with antibiotics reduced staphylococcal and C. acnes biofilm formation in vitro.

Differences in outcomes for hospitalizations of systemic and non-systemic infections associated with vascular and cardiac grafts and devices: a population-based study. J Hosp Infect 2020; 106:828-834. [PMID: 32896585 DOI: 10.1016/j.jhin.2020.09.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 09/01/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Use of vascular and cardiac devices has expanded and is associated with a relative, though disproportionate, increase in device-associated infections. AIM To describe the association between cardiac/vascular device infections and outcomes in those with, and without systemic infections. METHODS We used the 2016 National Inpatient Sample and the International Classification of Diseases - 10th revision codes to identify hospitalized individuals with vascular and cardiac device infections. Linear and logistic regression models were utilized to compare outcomes of death, length of stay (LOS) and hospitalization costs between individuals with and without systemic infection. FINDINGS There were a total of 65,110 hospitalizations associated with device infections with a mean age of 61.3 ± 15.9 years (standard deviation); 28,650 (44%) had systemic infections. Elixhauser comorbidity scores of three or greater were observed in 91.2% of individuals with systemic infections along with a higher prevalence of diabetes, renal disease and heart failure. The primary outcome of mortality was observed in 3965 individuals with an odds ratio of 3.97 (95% confidence interval (CI), 2.92-3.95) in those with systemic infections compared with those without. Mean LOS was 3.44 days longer (95% CI, 2.92-3.95) and mean cost was US$11,776 greater (95% CI, US$9826-12,727) in the systemic infection cohort. CONCLUSION Systemic cardiac and vascular device infections were associated with increased mortality, LOS and costs. Considering the increasing use of these life-saving devices, further work is needed to identify those at risk for infectious complications, particularly systemic infection, in order to enhance preventative strategies and improve health outcomes.

Clinical outcomes of patients undergoing a cardiac implantable electronic device implantation following a recent non-device-related infection. J Hosp Infect 2020; 105:272-279. [PMID: 32057789 DOI: 10.1016/j.jhin.2020.02.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 02/05/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Clinical outcomes of patients undergoing a cardiac implantable electronic device (CIED) implantation following a recent non-device related infection are unknown. AIM To evaluate the clinical outcomes of patients with recent infection before CIED implantation. METHODS Consecutive patients (N = 1237) were classified as patients with recent infection (N = 72) and without recent infection (N = 1165). A recent infection was established by reviewing medical records, including symptoms and clinical manifestations, diagnosis of systemic inflammatory response syndrome, and quick Sequential Organ Failure Assessment (qSOFA) score. Multiple stepwise logistic regression analysis was used to identify independent predictors of in-hospital all-cause mortality. FINDINGS During nearly three years of follow-up, 17 patients had CIED infection (1.4%), and the incidence of CIED infection did not significantly differ between patients with and without recent infection according to symptoms and clinical manifestations (2.8% vs 1.3%, respectively; not significant). However, patients with recent infection had a significantly higher in-hospital mortality rate compared to those without recent infection (22.2% vs 0.9%, respectively; P < 0.05). In multivariate analysis, predictors of in-hospital mortality were recent infection before CIED implantation (odds ratio: 20.3; 95% confidence interval: 8.4-49.3; P < 0.001) and end-stage renal disease (4.3; 1.4-12.8; P = 0.009). CONCLUSION A CIED implantation is feasible in patients with recent infection if the patient is afebrile and has received an adequate duration of antibiotic therapy. Participants in shared decision-making before implant should be advised that recent infection increases in-hospital mortality risk, especially in patients with a qSOFA score of ≥2.

Extraction of infected cardiac implantable electronic devices and the need for subsequent re-implantation. Int J Cardiol 2019; 309:84-91. [PMID: 31973885 DOI: 10.1016/j.ijcard.2019.12.044] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 12/12/2019] [Accepted: 12/23/2019] [Indexed: 12/24/2022]
Abstract
BACKGROUND Little is known about rates of re-implantation and outcomes of patients not implanted with a device after transvenous lead extraction (TLE) in cardiac device related infections (CDRI). METHODS All patients with CDRI were included in a prospective registry. After TLE, the indication for re-implantation was evaluated according to the patients' history and most recent cardiac examinations. All patients were followed for complications and mortality. In addition, in patients discharged without device the frequency of device implantations was analyzed. RESULTS Among 302 patients, only 123 (40.7%) met the indication for implantation of the same cardiac implantable electronic device (CIED), 68 (22.5%) received a different device and 111 (36.8%) patients were discharged without CIED. Reimplanted patients were younger (70 ± 11 vs. 73 ± 13 years; p = 0.004), more often male (83 vs. 69%, p = 0.006), had less systemic infection (38 vs. 60%; p < 0.001) and a higher prevalence of complete heart block (28 vs. 7%, p < 0.001). Reasons against re-implantation were: loss of indication (45%), never met indication (27%), patients' preference (17%), persistent infection (8%) and advanced age (3%). During 26 ± 18 months of follow-up, mortality in both groups was similar after adjusting for cofactors (HR 0.79; 95% CI 0.49-1.29; p = 0.352). CONCLUSION More than one third of patients undergoing TLE for CDRI in our study are not implanted with a new device. Careful evaluation of the initial CIED indication allows for detection of over treated patients and may avoid unnecessary device-related complications.

Staphylococcus aureus bloodstream infection in patients with ventricular assist devices-Management and outcome in a prospective bicenter cohort. J Infect 2018; 77:30-37. [PMID: 29778631 DOI: 10.1016/j.jinf.2018.05.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Revised: 04/30/2018] [Accepted: 05/10/2018] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Ventricular assist devices (VAD) are increasingly implanted in patients with terminal heart failure. Here we describe the clinical course, management and outcome of VAD patients with S. aureus bloodstream infection (SAB). METHODS We conducted a post hoc analysis of data from 1073 patients who had been prospectively enrolled in two consecutive SAB bicenter cohort studies. Patients with VAD in situ at the onset of SAB were identified. Follow-up of patients was at least 90 days. RESULTS Twelve VAD patients with SAB were identified. Compared to the overall cohort, patients with VAD presented more often with fever (92% vs. 65%) and septic shock (33% vs. 23%) and showed higher C-reactive protein levels (mean 244 vs. 132 g/ml). The median time to onset of SAB after device implantation was 161 days (range 24-790 days). 30-day mortality was comparable to the whole cohort (17% vs. 19%). Infection-related surgical interventions were performed in six patients. Hematogenous dissemination to distant foci was not found in any patient. One out of nine surviving patients required continuous suppressive antibiotic therapy. CONCLUSIONS Mortality rates for VAD patients with SAB were comparable to SAB without VAD. No hematogenous disssemination or persistent infections were recorded, which might be associated with the prompt and aggressive antibiotic and surgical management in VAD patients. SAB per se does not preclude successful transplantation.

Abstract
PURPOSE OF REVIEW This review analyzes recent studies evaluating the diagnostic value of 18F-FDG-PET/CT for the detection of peripheral emboli and secondary infectious foci in patients with infective endocarditis and cardiac device infections. RECENT FINDINGS Detection of extracardiac septic localizations in patients with infective endocarditis and cardiac device infections is crucial, as it may impact the diagnosis, prognosis, and therapeutic management. Recent literature substantiated the clinical usefulness of 18F-FDG-PET/CT in this setting. 18F-FDG-PET/CT has proven its high diagnostic value for the detection of peripheral emboli in patients with infective endocarditis and cardiac device infections, substantially affecting patients' outcome and treatment. A multimodal approach, combining the high sensitivity of 18F-FDG-PET/CT with morphological imaging seems promising.

Abstract
PURPOSE OF REVIEW Cardiovascular implantable electronic device (CIED) infections are highly morbid, common, and costly, and rates are increasing (Sohail et al. Arch Intern Med 171(20):1821-8 2011; Voigt et al. J Am Coll Cardiol 48(3):590-1 2006). Factors that contribute to the development of CIED infections include patient factors (comorbid conditions, self-care, microbiome), procedural details (repeat procedure, contamination during procedure, appropriate pre-procedural prep, and antimicrobial use), environmental and organizational factors (patient safety culture, facility barriers, such as lack of space to store essential supplies, quality of environmental cleaning), and microbial factors (type of organism, virulence of organism). Each of these can be specifically targeted with infection prevention interventions. RECENT FINDINGS Basic prevention practices, such as administration of systemic antimicrobials prior to incision and delaying the procedure in the setting of fever or elevated INR, are helpful for day-to-day prevention of cardiac device infections. Small single-center studies provide proof-of-concept that bundled prevention interventions can reduce infections, particularly in outbreak settings. However, data regarding which prevention strategies are the most important is limited as are data regarding the optimal prevention program for day-to-day prevention (Borer et al. Infect Control Hosp Epidemiol 25(6):492-7 2004; Ahsan et al. Europace 16(10):1482-9 2014). Evolution of infection prevention programs to include ambulatory and procedural areas is crucial as healthcare delivery is increasingly provided outside of hospitals and operating rooms. The focus on traditional operating rooms and inpatient care leaves the vast majority of healthcare delivery-including cardiac device implantations in the electrophysiology laboratory-uncovered.

Abstract
AIMS To determine the frequency, characteristics and risk factors of cardiac device infections in the Isala Hospital. METHODS We retrospectively studied all patients who underwent cardiac device procedures performed in the cardiac catheterisation lab and the operating room from 2010 to 2012. All patients who developed a cardiac device infection were reviewed for its characteristics. RESULTS 31/2026 patients developed a cardiac device infection (1.5 %). One (3.2 %) patient died within 30 days of hospitalisation. Device infection rates for procedures in the catheterisation lab and operating room were similar (p = 0.60). Positive cultures were present in 27/31 (87 %) cases. These consisted predominantly of micro-organisms that are part of the skin flora (84 %). The mean time between device procedure and infection was 14 ± 21 months (range 0-79). Cardiac device infection was significantly associated with device revision, (65 % were revisions in patients with device infection vs. 30 % revisions in patients without device infection, p = 0.011) and placement of a left ventricular lead in pacemaker implantations (59 % of patients with vs. 51 % of patients without device infection, p < 0.001). CONCLUSION The frequency of cardiac device infection was 1.5 % with a mortality of 3.2 % within 30 days, which is lower compared with other registries. Cardiac device infections were associated with device revisions and placement of left ventricular leads in pacemaker implantations.

Abstract
Infective endocarditis is a life-threatening disease caused by a focus of infection within the heart. For clinicians and scientists, it has been a moving target that has an evolving microbiology and a changing patient demographic. In the absence of an extensive evidence base to guide clinical practice, controversies abound. Here, we review three main areas of uncertainty: first, in prevention of infective endocarditis, including the role of antibiotic prophylaxis and strategies to reduce health care-associated bacteraemia; second, in diagnosis, specifically the use of multimodality imaging; third, we discuss the optimal timing of surgical intervention and the challenges posed by increasing rates of cardiac device infection.

Abstract
AIMS To evaluate the efficacy of bundled skin antiseptic preparation to prevent cardiac implantable electronic device (CIED) infections. METHODS AND RESULTS From January 2010 to November 2013, 665 consecutive patients were divided into two groups according to the strategy of skin preparation. In Period 1 (January 2010 to June 2012), 395 patients received the standard skin antiseptic preparation. In Period 2 (July 2012 to November 2013), 270 patients received a triple-step skin antiseptic preparation, 'bundled skin antiseptic preparation', consisting of applying 75% alcohol over anterior chest on the night before the index day, povidone-iodine 10 min before operation, and the standard skin antiseptic preparation before incision. During follow-up, the occurrence of CIED infection was recorded. Multiple logistic regression analysis was used to determinate the risk factors of CIED infection. During a mean follow-up of 26.9 ± 16.2 months, 20 episodes of CIED infection developed in 19 patients (2.9%), and the incidence of minor and major infection episodes was 2.2% and 0.8%, respectively. Patients with the bundled skin antiseptic preparation had a significantly lower incidence of CIED infection, compared with patients with the standard preparation (0.7 vs. 4.3%, P = 0.007). In multivariate analysis, pocket haematoma (P = 0.020), atrial fibrillation (P = 0.033), and complex procedures (P = 0.047) were independent predictors for CIED infection. In contrast, the bundled skin antiseptic preparation was a significant predictor against CIED infection (P = 0.014). CONCLUSION Pocket haematoma was the most important risk factor for CIED infection. The bundled skin antiseptic preparation strategy significantly reduced the risk of minor CIED infection.

Abstract
BACKGROUND Transvenous lead extraction (TLE) is a complex invasive procedure and the experience of the operator and the team is a major determinant of procedural outcomes. AIM Because of very limited data available on minimum procedural volumes to enable training and ongoing competency for TLEs, we performed a meta-analysis aimed at assessing the outcomes of TLE in the centres with low, medium, and high volume of procedures. METHODS Of the 280 papers initially retrieved until February 2013, 66 observational studies met inclusion criteria and were included in at least one stratified meta-analysis: 17 were prospective studies; 47 had a retrospective design; and 2 were defined 'experience studies'. We included only articles published after the introduction of laser technique (year 1999). We divided the studies in low, medium, and high volume centres utilizing either the European Heart Rhythm Association (EHRA) or Lexicon classification criteria. RESULTS When meta-analyses were carried out separately for the studies with larger and smaller sample sizes, either using EHRA or Lexicon classification criteria, no clear differences emerged in the combined rate of major complications or intraoperative deaths. In contrast, both minor complications and mortality at 30 days decreased as centre volume increased. CONCLUSIONS In our meta-analysis of observational studies, patients who have been treated in higher volume centres have a lower probability of minor complications and death at 30 days regardless of the infection rate, length of lead duration, type of device, and type of extraction.

Abstract
PURPOSE The infection of cardiac implantable electronic devices (CIED) is a serious and potentially lethal complication. The population at risk is growing, as the device implantation is increasing especially in older patients with associated comorbid conditions. Our purpose was to present the management of this complicated surgical condition and to extract the relevant conclusions. METHODS During a 3-year period 1,508 CIED were implanted in our hospital. We treated six cases of permanent pacemaker infection with localized pocket infection or endocarditis. In accordance to the recent AHA/ACC guidelines, complete device removal was decided in all cases. The devices were removed under general anaesthesia, with a midline sternotomy, under extracorporeal circulation on the beating heart. Epicardial permanent pacing electrodes were placed on the right atrium and ventricle before the end of the procedure. RESULTS The postoperative course of all patients was uncomplicated and after a follow up period of five years no relapse of infection occurred. CONCLUSIONS Management protocols that include complete device removal are the only effective measure for the eradication of CIED infections. Although newer technologies have emerged and specialized techniques of percutaneous device removal have been developed, the surgical alternative to these methods can be a safe solution in cases of infected devices.

Successful surgical removal of long-term implantable cardioverter defibrillator lead infection caused by methicillin-resistant Staphylococcus aureus in patients with dilated cardiomyopathy. J Cardiol Cases 2009; 1:e92-e94.

Abstract
The patient was a 67-year-old male who received implantable cardioverter defibrillator (ICD) due to dilated cardiomyopathy and ventricular tachycardia 10 years previously. In September 2007, he was admitted to our hospital for dilated cardiomyopathy accompanied by congestive heart failure. Since he suffered from pneumonia and respiratory insufficiency, he was treated with steroid, long-term artificial respirator, and central venous catheter placement. Congestive heart failure and pneumonia improved; however, he was diagnosed as having ICD lead infection and infective endocarditis because of a positive blood culture for methichillin-resistant Staphylococcus aureus (MRSA). After 2 months of appropriate anti-MRSA agent administration, the ICD lead was surgically removed and his tricuspid valve was replaced. The postoperative course was uneventful; a cardiac resynchronization therapy defibrillator (CRT-D) was reimplanted 6 weeks after lead extraction. We experienced a case with long-term ICD lead infection and lead-related infective endocarditis in the tricuspid valve caused by MRSA in a patient with poor cardiac function, which is the first successful case in Japan.
