Editorial to ‘Antibiotic envelope is associated with reduction in cardiac implantable electronic devices infections especially for high‐power device—Systematic review and meta‐analysis’

Abstract Background Sub-clinical atrial fibrillation (SCAF) and atrial high-rate episodes (AHREs), seen as high-frequency atrial tachyarrhythmias in patients with cardiac implantable electronic devices (CIEDs), have gained prominence as determinants of clinical atrial fibrillation (AF) and increased stroke risk. As a result, several studies investigating their role in predicting the onset of AF and AHRE-related outcomes have been conducted but uncertainty exists on the epidemiology of AHRE. Purpose To estimate the incidence of SCAF, according to presence of AHREs in patients with CIEDs, through a systematic review and meta-analysis of the available literature. Methods PubMed and EMBASE were searched from inception to 27th January 2021 for all studies documenting the incidence of AHREs in patients with CIEDs. We included all studies with ≥100 patients reporting data on AHREs incidence. Pooled prevalence and incidence rates were computed; we also performed meta-regressions for pooled incidence rates, according to relevant study-level characteristics. This study was registered in PROSPERO: CRD42019106994. Results Among the 2,515 results retrieved, we included 51 studies in the systematic review and meta-analysis, with a total of 68,414 patients. Meta-analysis of included studies showed a pooled prevalence of 28.2% (95% CI: 24.3–32.5%, I2=99%), with a pooled incidence rate (IR) of 15 new AHRE cases per 100 patient-years (95% CI: 12–19, I2=100%). Given the large heterogeneity showed in the pooled estimates we performed additional analyses. Regarding pooled prevalence, we performed several subgroup analyses, according to various studies baseline characteristics, which did not show any significant difference in any of the subgroups examined. Regarding IR, a multivariable meta-regression analysis showed that decreasing follow-up time and increasing age were the only factors significantly associated with AHRE incidence, explaining a large proportion of heterogeneity (R2=68%, p<0.001; Figure 1, Panel A and B respectively). Accordingly, the AHRE IR was highest at 1 year follow-up and in the oldest subjects. Presence of SCAF was significantly associated with older age, higher CHA2DS2-VASc score, and higher prevalence of hypertension, heart failure and history of cerebrovascular disease. Conclusions This systematic review and meta-regression demonstrated that SCAF is very common in patients with CIEDs, with an overall IR for AHREs of up to 15 per 100 patient-years; increasing with age and decreasing with longer follow-up time. Presence of SCAF was associated with an overall higher clinical risk profile compared to those subjects without SCAF. FUNDunding Acknowledgement Type of funding sources: None. Figure 1.

Abstract Recent guideline statements approve the performance of magnetic resonance imaging (MRI) in patients with non-conditional cardiac implantable electronic devices (CIEDs) under certain closely monitored conditions. Data from current registries may have lower power to discern changes that may occur in the CIED after the MRI. Objective We aimed to systematically review the literature to identify the adverse events and significance of changes in device function associated with performing MRI in patients with CIEDs Methods A comprehensive literature search of the databases was performed between 1980- 2017. Two independent reviewers selected studies and extracted data. A random-effects model was used for meta-analysis. Results A total of 7,422 patients underwent 8,865 MRI studies. No death occurred post MRI. Clinical adverse events were extremely rare (mostly less than 1%) and are summarized in Table 1. No significant changes in the pooled mean effect size estimate was noted for the changes in the lead parameters (pacing threshold, sensing and impedance) Binary outcomes post magnetic resonance imaging in patients with non-conditional cardiac implantable electronic devices Outcome Sample size Number of patients Rate SE LL of CI UL of CI Death 7401 0 0 0 0 0 Atrial arrhythmia 7173 10 0.001 0.0004 0.0007 0.0024 Ventricular arrhythmia 7371 9 0.0012 0.0004 0.0006 0.0022 Oversensing 4981 17 0.0034 0.0008 0.0020 0.0053 Inhibition of pacing 7371 6 0.0008 0.0003 0.0003 0.0016 Lead Failure/Generator Failure 7475/7475 2/8 0.0002/0.0011 0.0001/0.0004 0.0001/0.0005 0.0009/0.002 Power on Reset 1388 105 0.0131 0.0014 0.0107 0.0161 Did not complete scan 6851 13 0.0019 0.0005 0.0011 0.0031 Chest pain 7080 11 0.0021 0.0004 0.0008 0.0027.

Meta Regression Analysis

Abstract Aims In recent years, attention to subclinical atrial fibrillation (SCAF), defined as the presence of atrial high-rate episodes (AHREs), in patients with cardiac implantable electronic devices (CIEDs), has gained much interest as a determinant of clinical AF and stroke risk. To perform a systematic review and meta-regression of the available scientific evidence regarding the epidemiology of SCAF in patients receiving CIEDs. Methods and results PubMed and EMBASE were searched for all studies documenting the incidence of AHREs in patients (n = 100 or more) with CIEDs without any previous history of AF from inception to 20 August 2021, screened by two independent blind reviewers. This study was registered in PROSPERO: CRD42019106994. Among the 2614 results initially retrieved, 54 studies were included, with a total of 72 784 patients. Meta-analysis of included studies showed a pooled prevalence of SCAF of 28.1%, with an incidence rate (IR) of 16 new SCAF cases per 100 patient-years (I2 = 100%). Multivariate meta-regression analysis showed that age and follow-up time were the only significant determinants of IR, explaining a large part of the heterogeneity (R2 = 61.5%, P < 0.001), with higher IR at earlier follow-up and in older patients, decreasing over follow-up time and increasing according to mean age. Older age, higher CHA2DS2-VASc score, history of AF, hypertension, CHF, and stroke/TIA were all associated with SCAF occurrence. Conclusions In this systematic review and meta-regression analysis, IR of SCAF increased with age and decreased over longer follow-up times. SCAF was associated with older age, higher thromboembolic risk, and several cardiovascular comorbidities.

The Us

The aims of our systematic review were to quantify the expected rate of procedural success, early and late complications during CIED implantation using US-guided puncture of the axillary vein and to perform a meta-analysis of those studies that compared the US technique (intervention) versus conventional techniques (control) in terms of complication rates. MEDLINE, ISI Web of Science, and EMBASE were searched for eligible studies. Pooled Odds Ratio (OR) and Pooled Mean Difference (PMD) for each predictor were calculated. The quality of evidence (QOE) was evaluated according to the GRADE guidelines. Thirteen studies were included a total of 2073 patients. The overall success of US-guided venipuncture for CIED implantation was 96.8%. As regards early complications, pneumothorax occurred in 0.19%, arterial puncture in 0.63%, and severe hematoma/bleeding requiring intervention in 1.1%. No cases of hemothorax, brachial plexus, or phrenic nerve injury were reported. As regards late complications, the incidence of pocket infection, venous thromboembolism, and leads dislodgement was respectively 0.4%, 0.8%, and 1.2%. In the meta-analysis (five studies), the intervention group (US-guided venipuncture) had a trend versus a lower likelihood of having a pneumothorax (0.19% vs 0.75%, p = 0.21), pocket hematoma (0.8% vs 1.7%, p = 0.32), infection (0.28% vs 1.05%, p = 0.29) than the control group, but this did not reach statistical significance. The overall QOE was low or very low. In conclusions we found that the US-guided axillary venipuncture for CIEDs implantation was associated with a low incidence of early and late complications and a steep learning curve.

Effective Preventive Strategy

Introduction: Cardiac Implantable Electronic Device (CIED) infections are a major source of morbidity, mortality and increased healthcare cost. There are several well established risk factors associated with increased infection. An antibiotic coated envelope has been developed as an infection prevention intervention. Hypothesis: Whether antibiotic coated envelope is an effective preventive strategy against Cardiac Implantable Electronic Device Infections. Methods: 6 trials comparing use of antibiotic envelope to control, including 1 randomized trial and 5 cohort studies were selected using PubMed and Embase data bases through May 2019. The efficacy end point was prevention of CIED Infection. Outcomes were combined using random effects model and estimated by odds ratio with 95% confidence intervals (CI). Results: In our analysis of total 12,024 patients undergoing CIED implantation, 5,844 patients received antibiotic envelope while 6,180 patients were included in the control group. Antibiotic envelope was superior to control in reducing the risk of device infection (OR 0.40 CI [0.17-0.95], p=0.04). Conclusions: The use of antibiotic envelope in Cardiac Implantable Electronic Devices (CIED) is associated with reduced incidence of CIED infection.
