Abstract
OBJECTIVES To evaluate any association between non-sustained ventricular tachycardia (NSVT) detected by intra-cardiac device and clinical outcomes in repaired adult congenital heart disease (ACHD) without tetralogy of Fallot (TOF). BACKGROUND NSVT portends a higher risk of serious ventricular tachyarrhythmia in TOF. However its clinical significance when incidentally detected by implantable cardiac device is not well elucidated in non-TOF ACHD cohort. METHODS We performed a single center, retrospective, longitudinal follow-up study in repaired ACHD (≥ 18 years) patients without TOF who hosted a pacemaker or automatic implantable cardiac defibrillator (AICD). The cohort was divided based on presence/absence of device detected NSVT. The primary end-point was a composite of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), or sudden cardiac death (SCD). RESULTS 158 patients [male 56.3%, median (IQR) age of 35 (28-43) years at last follow-up] with longitudinal post-implant follow-up duration of 8 (5-12) years were included. NSVT was detected in 52 (33%) patients. The primary composite end-point was more frequent in NSVT group [11.5% vs. 2.8%; p = 0.04]. Patients with NSVT were i) older at the time of initial implant (age 25 vs. 18 years, p = 0.011) and more frequently demonstrated ii) systemic ventricular dysfunction (44% vs. 26%; p = 0.015), as well as iii) history of ventriculotomy (38% vs. 21%;p = 0.017). CONCLUSIONS In our repaired ACHD cohort, we noted a significant association between device-detected-NSVT and the primary composite end-point of sustained VT/VF or SCD. Systemic ventricular dysfunction and history of ventriculotomy were more frequent in the NSVT group and likely constituted the clinical milieu. This article is protected by copyright.

Abstract
Background Cardiovascular diseases (CVDs) and their complications are one of the most common causes of death worldwide. Implantable cardiac assistive devices (CADs) play a significant role in preventing dreadful outcomes, and the complication rate of these implanting procedures is minimal. These cardiac devices require some adaptation and could affect the patients' quality of life psychosocially and financially. This study is aimed to identify the impact of implantable cardiac assistive devices on patients' quality of life in the National Guard Hospital, Jeddah, Saudi Arabia. Methods This is an observational cross-sectional questionnaire-based study. It was conducted on patients who underwent cardiac assistive device implantation in National Guard Hospital. The patients were interviewed face-to-face and were requested to fill the Implanted Device Adjustment Scale (IDAS). Descriptive statistics were carried out. Chi-square test for independence was conducted to examine the associations between qualitative variables with the level of significance was taken as p-value <0.05. Results There was a statistically significant association between IDAS score and gender (p=0.03), monthly income (p=0.009), and type of cardiac implantation device (p=0.041). Females with an implantable cardiac defibrillator (ICD) and individuals with low socioeconomic status reported alongside divorced participants have higher IDAS scores, which correlates to worse adjustment. However, most of our patients scored 21-50 in IDAS score, which indicates a mild psychosocial effect after the cardiac assistive device implantation. Conclusion This study confirmed that most individuals adjust positively to implanted devices. It showed a significant association of gender, type of device, monthly income, and duration. Attention must be drawn to females and divorced patients in regards to psychological and emotional support.

Abstract
Sudden cardiac death (SCD) represents a major cause of death in end-stage kidney disease (ESKD). The precise estimate of its incidence is difficult to establish because studies on the incidence of SCD in ESKD are often combined with those related to sudden cardiac arrest (SCA) occurring during a haemodialysis (HD) session. The aim of the European Dialysis Working Group of ERA-EDTA was to critically review the current literature examining the causes of extradialysis SCD and intradialysis SCA in ESKD patients and potential management strategies to reduce the incidence of such events. Extradialysis SCD and intradialysis SCA represent different clinical situations and should be kept distinct. Regarding the problem, numerically less relevant, of patients affected by intradialysis SCA, some modifiable risk factors have been identified, such as a low concentration of potassium and calcium in the dialysate, and some advantages linked to the presence of automated external defibrillators in dialysis units have been documented. The problem of extra-dialysis SCD is more complex. A reduced left ventricular ejection fraction associated with SCD is present only in a minority of cases occurring in HD patients. This is the proof that SCD occurring in ESKD has different characteristics compared with SCD occurring in patients with ischaemic heart disease and/or heart failure and not affected by ESKD. Recent evidence suggests that the fatal arrhythmia in this population may be due more frequently to bradyarrhythmias than to tachyarrhythmias. This fact may partly explain why several studies could not demonstrate an advantage of implantable cardioverter defibrillators in preventing SCD in ESKD patients. Electrolyte imbalances, frequently present in HD patients, could explain part of the arrhythmic phenomena, as suggested by the relationship between SCD and timing of the HD session. However, the high incidence of SCD in patients on peritoneal dialysis suggests that other risk factors due to cardiac comorbidities and uraemia per se may contribute to sudden mortality in ESKD patients.

Abstract
Disconnecting a patient from artificial life support, on their request, is often if not always a matter of letting them die, not killing them-and sometimes, permissibly doing so. Stopping a patient's heart on request, by contrast, is a kind of killing, and rarely if ever a permissible one. The difference seems to be that procedures of the first kind remove an unwanted external support for bodily functioning, rather than intervening in the body itself. What should we say, however, about cases at the boundary-procedures involving items that seem bodily in some respects, but not others? When, for instance, does deactivating an implanted device like a pacemaker count as killing, and when as letting die? Contra existing proposals, I argue that the boundaries of the body for this purpose are not drawn at the boundaries of the self, or (if this is different) the human organism. Nor should we determine when we are killing and when we are letting die by deferring to existing practices for distinguishing ongoing from completed treatment. Rather, I argue that whether something (organic or inorganic) counts as body part for purposes of this distinction depends on the results of a normative analysis of the particular character of our rights in it-particularly, whether and in what way these rights ought to be alienable. I conclude by arguing that there are likely good reasons to recognize distinctively "bodily" rights and restrictions in at least some implantable devices.

Abstract
BACKGROUND The daily activity of pediatric patients with implantable cardiac devices provides behavioral evidence of functional outcomes. Modern devices provide continuous accelerometer data that are sensitive to movement, but normative values have not been published for pediatric activity rates. This study provides the first normative accelerometer data on activity rates in a large sample of pediatric cardiac device patients. METHODS Patients were between 3 and 18 years old (N = 1,905) and implanted with a cardiac device from a single device company, and enrolled in remote monitoring. RESULTS The median age at implant was 14 years (interquartile range = 12-16); 61.3% were male. Data for 4 weeks were extracted from a company database at 53 weeks postimplant and an average of daily activity was calculated. Daily average activity for all patients was 5.4 hours (standard deviation = 2.0). In a multivariate analysis, increased level of activity was associated with: being male, having a pacemaker versus implantable cardioverter defibrillator (ICD), epicardial device location, rate response turned off, having experienced a shock, and younger age. CONCLUSIONS These results provide the first baseline data of physical activity in children with implanted cardiac devices and provide a clinical guide to physical activity assessment in this population. Further, our data suggest physical activity in children with implantable cardiac devices may differ based on demographic variables, device type, device location, indication for implantation, and history of ICD shock.

Abstract
The management of atrial fibrillation (AF) is among the most challenging aspects of cardiology and uncertainties abound concerning stroke assessment and stroke risk reduction. Currently, AF is viewed as a dichotomous variable (fully present or absent) when it comes to stroke risk; there is no regard to the amount of AF either spontaneously or due to rhythm control strategies. For this reason, monitoring in patients with a known AF history, particularly after ablation, has focused on easily measured outcomes such as time to recurrence. However, emerging data suggest that thresholds exist between stroke risk and AF quantity as measured by either duration or burden. As a result, there is an increasing interest in long-term continuous monitoring following a rhythm control strategy to assess efficacy beyond typical symptom reduction. Insertable cardiac monitors (ICMs) with AF-sensing algorithms and remote data transmission capabilities can be used for this purpose, and wearable devices with similar functions are on the horizon. In addition to their diagnostic potential, these tools are also being used therapeutically with efforts to target anticoagulation therapy only in response to AF episodes.

Abstract
BACKGROUND Remote monitoring is increasingly used in the follow-up of patients with cardiac implantable electronic devices. Data on paediatric populations are still lacking. The aim of our study was to follow-up young patients both in-hospital and remotely to enhance device surveillance. METHODS This is an observational registry collecting data on consecutive patients followed-up with the CareLink system. Inclusion criteria were a Medtronic device implanted and patient's willingness to receive CareLink. Patients were stratified according to age and presence of congenital/structural heart defects (CHD). RESULTS A total of 221 patients with a device - 200 pacemakers, 19 implantable cardioverter defibrillators, and two loop recorders--were enrolled (median age of 17 years, range 1-40); 58% of patients were younger than 18 years of age and 73% had CHD. During a follow-up of 12 months (range 4-18), 1361 transmissions (8.9% unscheduled) were reviewed by technicians. Time for review was 6 ± 2 minutes (mean ± standard deviation). Missed transmissions were 10.1%. Events were documented in 45% of transmissions, with 2.7% yellow alerts and 0.6% red alerts sent by wireless devices. No significant differences were found in transmission results according to age or presence of CHD. Physicians reviewed 6.3% of transmissions, 29 patients were contacted by phone, and 12 patients underwent unscheduled in-hospital visits. The event recognition with remote monitoring occurred 76 days (range 16-150) earlier than the next scheduled in-office follow-up. CONCLUSIONS Remote follow-up/monitoring with the CareLink system is useful to enhance device surveillance in young patients. The majority of events were not clinically relevant, and the remaining led to timely management of problems.

Abstract
BACKGROUND AND AIM Implantable cardiac devices are a relative contraindication to video capsule endoscopy (VCE) because of concerns regarding interference. As a result of a lack of alternatives, some centers have adopted protocols to allow for VCE in these patients. There are minimal published descriptions of the gastrointestinal outcomes of these procedures. We investigated the completion rate and diagnostic yield of VCE carried out in outpatients with implantable cardiac devices. METHODS We carried out a retrospective review of all VCE from April 2010 through March 2013 at our center. Patients that underwent VCE through a specialized protocol for outpatients with implantable cardiac devices were identified. The protocol used telemetry for cardiac monitoring during battery lifespan of the VCE. Demographic data, procedure indications, results and any procedural events were collected. RESULTS Twenty-one patients met the study criteria, with 16 (76%) pacemakers, four (19%) implantable cardioverter defibrilla tors and one (5%) implantable hemodynamic monitor. Two (10%) devices were adjusted prior to VCE. Twenty (95%) were completed to the colon, with a median gastric transit time of 18 min and a small bowel transit time of 216 min. The procedure was diagnostic in 13 (62%) patients. One (5%) capsule retention event occurred. No cardiac events or video capture disturbances occurred. CONCLUSIONS Video capsule endoscopy done on outpatients with implantable cardiac devices through a cardiac monitoring protocol resulted in a satisfactory completion rate and high diagnostic yield with no adverse cardiac events. A large prospective trial is needed to confirm these novel results.

Abstract
Infections related to implantable cardiac electronic devices (ICEDs), including pacemakers, implantable cardiac defibrillators and cardiac resynchronization therapy devices, are increasing in incidence in the USA and are likely to increase in the UK, because more devices are being implanted. These devices have both intravascular and extravascular components and infection can involve the generator, device leads and native cardiac structures or various combinations. ICED infections can be life-threatening, particularly when associated with endocardial infection, and all-cause mortality of up to 35% has been reported. Like infective endocarditis, ICED infections can be difficult to diagnose and manage. This guideline aims to (i) improve the quality of care provided to patients with ICEDs, (ii) provide an educational resource for all relevant healthcare professionals, (iii) encourage a multidisciplinary approach to ICED infection management, (iv) promote a standardized approach to the diagnosis, management, surveillance and prevention of ICED infection through pragmatic evidence-rated recommendations, and (v) advise on future research projects/audit. The guideline is intended to assist in the clinical care of patients with suspected or confirmed ICED infection in the UK, to inform local infection prevention and treatment policies and guidelines and to be used in the development of educational and training material by the relevant professional societies. The questions covered by the guideline are presented at the beginning of each section.

Abstract
Due to expanding clinical indications and an aging society there has been an increase in the use of implantable pacemakers. At the same time, due to increased diagnostic yield over other imaging modalities and the absence of ionizing radiation, there has been a surge in demand for magnetic resonance imaging (MRI) assessment, of both cardiac and noncardiac conditions. Patients with an implantable device have a 50-75% chance of having a clinical indication for MRI during the lifetime of their device. The presence of an implantable cardiac device has been seen as a relative contraindication to MRI assessment, limiting the prognostic and diagnostic utility of MRI in many patients with these devices. The introduction of MRI conditional pacemakers will enable more patients to undergo routine MRI assessment without risk of morbidity or device malfunction. This review gives a general overview of the principles and current evidence for the use of MRI conditional implantable cardiac devices. Furthermore, we appraise the differences between those pacemakers currently released to market.
