Psychiatric functioning and quality of life in young patients with cardiac rhythm devices

The Effects of Cardiac Implantable Electronic Device Personal Protective Equipment Use in Patients with Pediatric and Adult Congenital Heart Disease

Pediatric and adult congenital heart disease (ACHD) patients encounter physical and emotional barriers. Cardiac implantable electronic devices (CIEDs), including pacemakers and implantable cardiac defibrillators (ICD) often compound these issues. Patient fear associated with damaging the CIED system can lead to avoidance of physical activity and reduced quality of life (QOL). CIED personal protective equipment (PPE) is a potential treatment for decreasing this fear. We sought to determine the effects of CIED PPE use in the pediatric and ACHD population. Patients 5 years or older with a CIED at a single pediatric and ACHD heart rhythm center received a CIED protector and customized athletic shirt. QOL was assessed using the PedsQL TM 4.0 SF15 prior to and after 6-12 months. Of the 77 patients enrolled, 26 completed repeat assessment. The mean age at enrollment was 15.6 years (range 5-36) with a mean device age of 2.2 years (< 1-10 years). Pacemakers were present in 77% and 23% had ICDs. The PPE was used in 92% with no PPE malfunction. Fear associated with physical activity was reduced, z = - 4, p < 0.001, with a large effect size (r = 0.55). There was a trend toward increased physical activity. Total QOL scores improved, z = - 2.771, P < 0.05, with a medium effect size (r = 0.4). This first study of CIED PPE in children shows that providing CIED PPE to pediatric and ACHD patients may decrease their fear of damaging their device system, increasing physical activity levels, and improving quality of life.

Prediction of Sudden Death Risk in Patients with Congenital Heart Diseases

Risk stratification for sudden death should be discussed with patients with congenital heart disease at each stage of personal and cardiac development. For most patients, risk is low through teenage years and the critical factors to consider are anatomy, ventricular function, and symptoms. By adulthood, these are supplemented by screening for atrial arrhythmias, ventricular arrhythmias, and pulmonary hypertension. Therapies include medication, ablation, and defibrillator placement.

Cost of Pacing in Pediatric Patients With Postoperative Heart Block After Congenital Heart Surgery

Importance

Surgical correction of congenital heart defects (CHDs) has improved the lifespan and quality of life of pediatric patients. The number of congenital heart surgeries (CHSs) in children has grown continuously since the 1960s. This growth has been accompanied by a rise in the incidence of postoperative heart block requiring permanent pacemaker (PPM) implantation.

Objective

To assess the trends in permanent pacing after CHS and estimate the economic burden to patients and their families after PPM implantation.

Design, Setting, and Participants

In this economic evaluation study, procedure- and diagnosis-specific codes within a single-institution database were used to identify patients with postoperative heart block after CHS between January 1, 1960, and December 31, 2018. Patients younger than 4 years with postoperative PPM implantation were selected, and up to 20-year follow-up data were used for cost analysis based on mean hospital event charges and length of stay (LOS) data. Data were analyzed from January 1, 2020, to November 30, 2022.

Exposure

Implantation of PPM after CHS in pediatric patients.

Main Outcomes and Measures

Annual trends in CHS and postoperative PPM implantations were assessed. Direct and indirect costs associated with managing conduction health for the 20 years after PPM implantation were estimated using Markov model simulation and patient follow-up data.

Results

Of the 28 225 patients who underwent CHS, 968 (437 female [45.1%] and 531 male [54.9%]; 468 patients aged <4 years) received a PPM due to postoperative heart block. The rate of CHS and postoperative PPM implantations increased by 2.2% and 7.2% per year between 1960 and 2018, respectively. In pediatric patients younger than 4 years with PPM implantation, the mean (SD) 20-year estimated direct and indirect costs from Markov model simulations were $180 664 ($32 662) and $15 939 ($1916), respectively. Using follow-up data of selected patients with clinical courses involving 1 or more complication events, the mean (SD) direct and indirect costs were $472 774 ($212 095) and $36 429 ($16 706), respectively.

Conclusions and Relevance

In this economic evaluation study, the cost of PPM implantation in pediatric patients was found to accumulate over the lifespan. This cost may represent not only a substantial financial burden but also a health care burden to patient families. Reducing the incidence of PPM implantation should be a focused goal of CHS.

Feasibility and Caregiver Receptiveness to Anxiety Screening in Pediatric Cardiology Clinic: A Pilot Study

Children with chronic medical conditions, including heart disease, have increased susceptibility to behavioral health concerns. We sought to evaluate the feasibility and parental opinion of anxiety screening in pediatric cardiology clinic. The PROMIS Pediatric Anxiety v2.0 Short Form 8a (PA2-S8) questionnaire was administered to 48 patients presenting to pediatric cardiology clinic for follow-up care. Parents/caregivers were asked their opinion on anxiety screening in cardiology clinic. The survey was completed by 47 out of 48 participants (median age 13, range 9-17). Fourteen (30%) participants had scores suggestive of increased anxiety symptomatology. No trends were identified between PA2-S8 score and age at diagnosis (P = .13), age at survey administration (P = .28), number of lifetime procedures (P = .89), number of noncardiac specialists (P = .13), or underlying cardiac diagnoses (P = .55). Most families (76%) were in favor of the screening effort. This study suggests that anxiety screening in cardiology clinic is both feasible and well-received by families.

Indications and management of implantable cardioverter-defibrillator therapy in childhood hypertrophic cardiomyopathy

Sudden cardiac death is the most common mode of death during childhood and adolescence in hypertrophic cardiomyopathy, and identifying those individuals at highest risk is a major aspect of clinical care. The mainstay of preventative therapy is the implantable cardioverter-defibrillator, which has been shown to be effective at terminating malignant ventricular arrhythmias in children with hypertrophic cardiomyopathy but can be associated with substantial morbidity. Accurate identification of those children at highest risk who would benefit most from implantable cardioverter-defibrillator implantation while minimising the risk of complications is, therefore, essential. This position statement, on behalf of the Association for European Paediatric and Congenital Cardiology (AEPC), reviews the currently available data on established and proposed risk factors for sudden cardiac death in childhood-onset hypertrophic cardiomyopathy and current approaches for risk stratification in this population. It also provides guidance on identification of individuals at risk of sudden cardiac death and optimal management of implantable cardioverter-defibrillators in children and adolescents with hypertrophic cardiomyopathy.

Psychological Distress and Quality of Life in Participants Undergoing Genetic Testing for Arrhythmogenic Right Ventricular Cardiomyopathy Caused by TMEM43 p.S358L: Is It Time to Offer Population-Based Genetic Screening?

PURPOSE

We have identified 27 families in Newfoundland and Labrador (NL) with the founder variant TMEM43 p.S358L responsible for 1 form of arrhythmogenic right ventricular cardiomyopathy. Current screening guidelines rely solely on cascade genetic screening, which may result in unrecognized, high-risk carriers who would benefit from preemptive implantable cardioverter-defibrillator therapy. This pilot study explored the acceptability among subjects to TMEM43 p.S358L population-based genetic screening (PBGS) in this Canadian province.

METHODS

A prospective cohort study assessed attitudes, psychological distress, and health-related quality of life (QOL) in unselected individuals who underwent genetic screening for the TMEM43 p.S358L variant. Participants (n = 73) were recruited via advertisements and completed 2 surveys at baseline, 6 months, and 1 year which measured health-related QOL (SF-36v2) and psychological distress (Impact of Events Scale).

RESULTS

No variant-positive carriers were identified. Of those screened through a telephone questionnaire, >95% felt positive about population-genetic screening for TMEM43 p.S358L, though 68% reported some degree of anxiety after seeing the advertisement. There were no significant changes in health-related QOL or psychological distress scores over the study period.

CONCLUSION

Despite some initial anxiety, we show support for PBGS among research subjects who screened negative for the TMEM43 p.S358L variant in NL. These findings have implications for future PBGS programs in the province.

Psychosocial outcomes in pediatric patients with ventricular assist devices and their families: A systematic review

Ventricular assist device (VAD) therapy has provided pediatric patients with severe heart failure new therapeutic options. However, pediatric patients and families receiving VAD therapy also experience psychosocial challenges. No synthesis of the literature on psychosocial outcomes within the pediatric VAD population has been conducted; thus, the current review sought to systematically investigate the impact of pediatric VAD on patient, parent, and family psychosocial outcomes and assess variables associated with poorer outcomes. Literature searches were conducted in PsycInfo, PubMed, and Cumulative Index to Nursing and Allied Health Literature databases and full texts were assessed according to pre-established inclusion criteria. Main findings and study quality were reviewed. Sixteen studies were included in the present review. Findings highlighted the likelihood for psychological sequelae among pediatric patients and families receiving VAD therapy, including decreased psychological and emotional well-being, elevated stress, and difficulty coping with changes to family dynamics and responsibilities. Health-related quality of life was reported comparable to that of healthy peers and children with other cardiac conditions. Patients and families on VAD therapy experience significant difficulties in psychological well-being and challenges related to adjustment. The current review underscores the importance of ongoing support for families and continued assessment of psychosocial functioning across VAD support. Three critical periods for increased distress were identified: 1) immediately following VAD implantation, 2) discharge home and the weeks following discharge, and 3) long-term VAD therapy.

Posttraumatic stress disorder prevalence in medical populations: A systematic review and meta-analysis

OBJECTIVE

PTSD is increasingly recognized following medical traumas although is highly heterogeneous. It is difficult to judge which medical contexts have the most traumatic potential and where to concentrate further research and clinical attention for prevention, early detection and treatment. The objective of this study was to compare PTSD prevalence in different medical populations.

METHODS

A systematic review of the literature on PTSD following medical traumas was conducted as well as a meta-analysis with final pooled result and 95% confidence intervals presented. A meta-regression was used to investigate the impact of potential effect modifiers (PTSD severity, age, sex, timeline) on study effect size between prevalence studies.

RESULTS

From 3278 abstracts, the authors extracted 292 studies reporting prevalence. Using clinician-administered reports, the highest 24 month or longer PTSD prevalence was found for intraoperative awareness (18.5% [95% CI=5.1%-36.6%]) and the lowest was found for epilepsy (4.5% [95% CI=0.2%-12.6%]). In the overall effect of the meta-regression, only medical events or procedures emerged as significant (p = 0.006) CONCLUSION: This review provides clinicians with greater awareness of medical contexts most associated with PTSD, which may assist them in the decision to engage in more frequent, earlier screening and referral to mental health services.

Outcomes of Pediatric Patients With Defibrillators Following Initial Presentation With Sudden Cardiac Arrest

BACKGROUND

Implantable cardioverter defibrillators (ICD) are recommended for secondary prevention after sudden cardiac arrest (SCA). The outcomes of pediatric patients receiving an ICD after SCA remain unclear. The objective of this study is to evaluate outcomes, future risk for appropriate shocks, and identify characteristics associated with appropriate ICD therapy during follow-up.

METHODS

Multicenter retrospective analysis of patients (age ≤21 years) without prior cardiac disease who received an ICD following SCA. Patient/device characteristics, cardiac function, and underlying diagnoses were collected, along with SCA event characteristics. Patient outcomes including complications and device therapies were analyzed.

RESULTS

In total, 106 patients were included, median age 14.7 years. Twenty (19%) received appropriate shocks and 16 (15%) received inappropriate shocks (median follow-up 3 years). First-degree relative with SCA was associated with appropriate shocks (P<0.05). In total, 40% patients were considered idiopathic. Channelopathy was the most frequent late diagnosis not made at time of presentation. Neither underlying diagnosis nor idiopathic status was associated with increased incidence of appropriate shock. Monomorphic ventricular tachycardia (hazard ratio, 4.6 [1.2-17.3]) and family history of sudden death (hazard ratio, 6.5 [1.4-29.8]) were associated with freedom from appropriate shock in a multivariable model (area under the receiver operating characteristic curve, 0.8). Time from diagnoses to evaluation demonstrated a nonlinear association with freedom from appropriate shock (P=0.015). In patients >2 years from implantation, younger age (P=0.02) and positive exercise test (P=0.04) were associated with appropriate shock.

CONCLUSIONS

The risk of future device therapy is high in pediatric patients receiving an ICD after SCA, irrelevant of underlying disease. Lack of a definitive diagnosis after SCA was not associated with lower risk of subsequent events and does not obviate the need for secondary prophylaxis.

A systematic concept analysis of 'technology dependent': challenging the terminology

There are an increasing number of children who are dependent on medical technology to sustain their lives. Although significant research on this issue is taking place, the terminology used is variable and the concept of technology dependence is ill-defined. A systematic concept analysis was conducted examining the attributes, antecedents, and consequences of the concept of technology dependent, as portrayed in the literature. We found that this concept refers to a wide range of clinical technology to support biological functioning across a dependency continuum, for a range of clinical conditions. It is commonly initiated within a complex biopsychosocial context and has wide ranging sequelae for the child and family, and health and social care delivery.Conclusion: The term technology dependent is increasingly redundant. It objectifies a heterogenous group of children who are assisted by a myriad of technology and who adapt to, and function with, this assistance in numerous ways. What is Known: • There are an increasing number of children who require medical technology to sustain their life, commonly referred to as technology dependent. This concept analysis critically analyses the relevance of the term technology dependent which is in use for over 30 years. What is New: • Technology dependency refers to a wide range of clinical technology to support biological functioning across a dependency continuum, for a range of clinical conditions. It is commonly initiated within a complex biopsychosocial context and has wide-ranging sequelae for the child and family, and health and social care delivery. • The paper shows that the term technology dependent is generally portrayed in the literature in a problem-focused manner. • This term is increasingly redundant and does not serve the heterogenous group of children who are assisted by a myriad of technology and who adapt to, and function with, this assistance in numerous ways. More appropriate child-centred terminology will be determined within the TechChild project.

Impact of Pacemakers and Implantable Cardioverter Defibrillators on the Psychosocial Functioning of Paediatric Patients

Although implanted cardiac devices improve patients' physical health, long-term psychosocial effects especially in the paediatric population are still unknown. The aim of this study was to evaluate the psychosocial effects of cardiac devices in a paediatric population.Pediatric Quality of Life Questionnaire (PedsQoL) was used to evaluate life quality, Connor-Davidson Resilience Scale was used to evaluate resilience and Brief Symptom Inventory was used to evaluate psychiatric symptoms in a paediatric population with cardiac devices.Seventy-one patients were enrolled in the study. Fifty of them (70.5%) had a cardiac pacemaker and 21 of them (29.5%) had implantable cardioverter defibrillator. When compared to the control group both implantable cardioverter defibrillator and pacemaker using patients had lower quality of life (79.5 ± 12.4 versus 86.7 ± 12.1, p = 0.001) but no difference was observed in resilience and psychological pathologies. Age, gender, family size, and education level had no effect on quality of life. Implantable cardioverter defibrillator bearing patients had higher levels of anxiety than pacemaker patients (0.58 versus 0.30 p = 0.045), and implantable cardioverter defibrillator patients who had received shock in the last year had higher levels of somatisation than the group that did not receive device shock (0.17 versus 0.44 p = 0.022).In conclusion study showed that cardiac devices have negative effects on the psychosocial health of children. Cardiologist working with these patients should be aware of these pathologies and monitor not only physical health but also psychosocial health too.

Comparison of depression and anxiety among pacemaker and implantable cardioverter-defibrillator recipients: A cross-sectional study

INTRODUCTION

Anxiety and depression among implantable cardioverter-defibrillator (ICD) recipients can lead to physical or psychological consequences and reduce the quality of life of these patients. Few studies have compared the frequency and severity of depressive and anxiety disorders in the pacemaker (PM) and ICD recipients. The aim of the present study was to compare depression and anxiety among PM and ICD recipients.

METHODS

This cross-sectional study was performed on 296 patients referred to a specialized cardiology teaching hospital from October 1, 2019 to July 1, 2020. Patients were selected using convenience sampling method.

RESULTS

Regarding anxiety, the results showed that the overall prevalence of anxiety in PM, ICD, and control groups was 23.5%, 28%, and 8%, respectively. Results showed no significant difference between PM and ICD recipients regarding the anxiety prevalence (p = .46). With regard to depression, the results showed that the overall prevalence of depression in the PM, ICD, and control groups was 7.1%, 23%, and 4.1%, respectively. The results showed a significant difference between PM and ICD recipients in terms of depression prevalence (p = .03). The results also showed that the prevalence of depression was significantly higher among PM and ICD recipients than the control group (p = .01).

CONCLUSION

Considering the results of the present study and the high prevalence of anxiety and depression, it seems necessary to focus more on educating patients about the effectiveness of PM and ICD devices in reducing anxiety and depression.

Quality of life and psychological co-morbidities in children and adolescents with cardiac pacemakers and implanted defibrillators: a cohort study in Eastern Germany

INTRODUCTION

The implantation of a pacemaker or an implantable cardioverter-defibrillator during childhood may reduce quality of life and lead to mental health problems. This study aimed to evaluate potential mental health problems (i.e., depressive and anxiety symptoms) and quality of life in children with cardiac active devices in comparison to healthy peers.

METHODS

We analysed data of children with pacemakers or implantable cardioverter-defibrillators aged 6-18 years. Quality of life, depressive and anxiety symptoms were assessed by standardised questionnaires. The results were compared to age-matched reference groups.

RESULTS

Children with implantable cardioverter-defibrillator showed significant lower quality of life in comparison to reference group (p = 0.03), but there was no difference in quality of life between children with pacemaker and reference group. There was no significant difference in depressive symptoms between children with a cardiac rhythm device compared to reference group (self-report: p = 0.67; proxy report: p = 0.49). There was no significant difference in anxiety (p = 0.53) and depressive symptoms (p = 0.86) between children with pacemaker and children with implantable cardioverter-defibrillator.

CONCLUSIONS

Living with an implantable cardioverter-defibrillator in childhood seems to decrease the patients' quality of life. Although children with pacemaker and implantable cardioverter-defibrillator don't seem to show more depressive and anxiety symptoms in comparison to their healthy peers, there still can be an increased risk for those children to develop mental health problems. Therefore, treating physicians should be aware of potential mental health problems and provide the patients and their families with appropriate therapeutic offers.

Health-related quality of life outcomes in pediatric patients with cardiac rhythm devices: a cross-sectional study with case-control comparison

Background

Little is known about health-related quality of life (HRQoL) in pediatric patients with cardiac rhythm devices. This study aims to compare self- and proxy-reported HRQoL in patients with pacemaker (PM) and implantable cardioverter-defibrillator (ICD) to that in sex- and age-matched healthy controls and to examine predictors for generic and disease-specific HRQoL.

Methods

The study included 72 PM and ICD patients (39% females) and 72 sex- and age-matched healthy controls from 3 to 18 years of age. HRQoL data was obtained by the PedsQL 4.0 Generic Core Scales and Pediatric Cardiac Quality of Life Inventory. Medical data was collected retrospectively from medical records.

Results

Patients had significantly lower self- and proxy-reported generic overall HRQoL and lower physical health than healthy controls, and ICD patients also had lower psychosocial health. On multivariate analyses, generic overall HRQoL and physical health was significantly predicted by current cardiac medication (β = −.39, p = .02 for overall HRQoL, respectively β = −.44, p = .006 for physical health). Disease-specific overall HRQoL was only marginally predicted by child age, device type, and the presence of a structural congenital heart disease (p < .10).

Conclusions

This study shows that PM and ICD patients have lower HRQoL than healthy controls and that patients who need cardiac medication are seen by their parents at great risk for lower generic overall HRQoL. Our study also indicates a trend towards higher risk for low disease-specific HRQoL in younger patients, ICD patients, and patients with a structural congenital heart disease. Special attention should be given to these patients as they may benefit from a timely clinical evaluation in order to provide supportive interventions.

Allowing Adolescents to Weigh Benefits and Burdens of High-stakes Therapies

We present the case of a girl aged 17 years and 10 months who has a strong family history of long QT syndrome and genetic testing confirming the diagnosis of long QT syndrome in the patient also. She was initially medically treated with β-blocker therapy; however, after suffering 1 episode of syncope during exertion, she underwent placement of an implantable cardioverter defibrillator. Since then, she has never had syncope. However, during the few months before this presentation, she experienced shocks on multiple occasions without any underlying arrhythmias. These shocks are disconcerting for her, and she is having significant anxiety about them. She requests the defibrillator to be inactivated. However, her mother, who also shares the diagnosis of long QT syndrome, disagrees and wants the defibrillator to remain active. The ethics team is consulted in this setting of disagreement between an adolescent, who is 2 months shy of the age of maturity and medical decision-making, and her mother, who is currently responsible for her medical decisions. The question for the consultation is whether it would be ethically permissible for the doctors to comply with the patient's request to turn off the defibrillator or whether the doctors should follow the mother's wishes until the patient is 18 years of age.

[Cardiac implantable electronic devices and health-related quality of life]

Patients, scientists and healthcare providers are increasingly interested in identifying interventions that not only reduce mortality but also improve symptoms, function and health-related quality of life. Health-related quality of life is a strong, independent predictor of mortality, cardiovascular events, hospitalization and treatment costs in patients with cardiac diseases. Remote monitoring of pacemakers has a positive effect on health-related quality of life and functional capacity and is equivalent to monitoring these patients in hospitals. Implantation of an implantable cardioverter defibrillator has a major impact on mental health, with the majority of patients experiencing the fear of ICD shocks as particularly detrimental to the quality of life. Variables, such as age, gender and duration of implantation should be considered in the assessment and planning of strategies for improving the quality of life of patients with electronic implantable cardiac devices.

Posttraumatic stress and health-related quality of life in parents of children with cardiac rhythm devices

PURPOSE

Studies have shown a high prevalence of post-traumatic stress disorders (PTSD) among parents of children with life-threatening diseases. However, it is yet unknown whether parents of children with cardiac rhythm device develop posttraumatic stress symptoms or even PTSD.

METHODS

This cross-sectional investigation is part of a comprehensive single-center study of long-term medical and psychosocial outcomes in pediatric patients with pacemaker (PM) and implantable cardioverter defibrillator (ICD). 69 patients (78%) were included in the study, with the participation of 69 mothers and 57 fathers. Parents completed the Posttraumatic Diagnostic Scale and Medical Outcomes Study Short Form-36 item questionnaire. Child's medical data was collected retrospectively from patients' hospital records.

RESULTS

At assessment, the patients (39% females) were on average 11.2 years old. The predominant device type was PM in 56 cases (81%). The mean time since device implantation was 6.3 years (SD = 4.3). Full heart-disease related PTSD was diagnosed in one mother and no father, while partial heart-disease-related PTSD was diagnosed in 3 mothers (4%) and 2 fathers (4%). Parental HRQoL-especially regarding the mental health dimension-was affected in both parents. In both parents, total PTSD symptom severity scores were a significant predictor for mental health summary scores after controlling for child age at implantation, presence of other non-cardiac disease in the child, parental age, and presence of own chronic disease.

CONCLUSIONS

Special attention should be given to parental PTSD symptoms in the clinical follow-up of PM and ICD patients as some parents might probably benefit from psychological support.

Health-Related Quality of Life and Psychological Adjustment of Children and Adolescents with Pacemakers and Implantable Cardioverter Defibrillators: A Systematic Review

The absence of cardiac symptoms, the improved exercise tolerance and the increased life expectancy are the advantages of a successful cardiac device therapy. Nevertheless, the fact of a lifelong device dependency, the inherent possibility of device malfunction and the progression of the underlying heart disease may impact the health-related quality of life (HRQoL) and the psychological adjustment of these individuals. To date, an overview of findings on these topics is lacking. The objective of this study was to evaluate and summarize the current evidence on generic and disease-specific HRQoL and psychological adjustment in paediatric patients with a pacemaker (PM) or an implantable cardioverter defibrillator (ICD). A systematic literature search was conducted using relevant databases and predefined keywords. Study selection was conducted based on predefined inclusion criteria. Fourteen studies were selected which were of varying methodological quality. Overall, the studies indicated that PM/ICD patients themselves and their parents scored lower than healthy controls on generic HRQoL scales and reported similar disease-related HRQoL as patients with severe forms of congenital heart disease. Regarding psychological adjustment outcome, PM recipients and norms were not significantly different with respect to anxiety and depression symptoms, while ICD patients showed more signs of anxiety than depression. HRQoL and psychological health should be considered when setting therapy goals and evaluating medical treatment success. This approach allows an early intervention in patients at risk of maladaptation, which is especially important in the young patient undergoing crucial developmental stages.

The psychological impact of permanent cardiac pacemakers on pediatric patients and their parents: A case control study

BACKGROUND

This study assessed anxiety and depression in children with permanent pacemakers (PPM) and quality of life of their parents.

METHODS

Ninety children (63.3% males and 36.6% females) and their parents were included in the study and were divided into three groups. The control group (Group 1) included 30 normal healthy children (57% males and 43% females), the PPM group (Group 2) included 30 age-matched children (70% males and 30% females) with PPM and structurally normal heart, while the Group 3 included 30 children (63% males and 37% females) with PPM and congenital heart disease (PPM+CHD). Psychological assessment of children and their parents was carried out using an interview-based questionnaires.

RESULTS

Psychiatric disorders were more prevalent in PPM+CHD group including depression (P=0.04), anxiety (P=0.02) and lower parents' QoL (P=0.01). The PPM group had higher depression and lower parents' QoL than the control group. Family income was independent factor for depression (r2=-6.3, with P<0.05). Sex of the child and CCU admission were independent factors for anxiety (r2=-9.5, P<0.05 & r2=10.5, P=0.001) in PPM group.

CONCLUSION

Children with pacemakers have higher psychiatric disorders and their parents have lower QoL.

The Capture Gap: Implantable Cardioverter-Defibrillator Quality of Life

We aimed to compare salient characteristics and antecedents of quality of life (QOL) in adolescents and young adults with implantable cardioverter-defibrillators (ICDs) from qualitative methods with quantitative measurement of QOL and correlations between QOL (PedsQL) and measured participant characteristics. Concurrent parallel mixed methods design was used to collect survey data from the PedsQL electronic health record, demographic questionnaire, and semistructured interview data. A convenience sample of 16 individuals with ICDs, aged 13 to 25 years, was obtained from a tertiary pediatric facility. Overall QOL and subdomains of physical, psychosocial, and academic/work were examined by PedsQL and visual analog scale. Select demographics were collected to develop a participant profile. Females with ICDs appear to be at risk of poor QOL given some unknown factors. Financial status of the individual and the family was positively related to QOL. For new ICD persons involved in physical activities that must be stopped, peer support appears to improve QOL.

Decreased inappropriate shocks with new generation ICDs in children and patients with congenital heart disease

OBJECTIVE

Inappropriate implantable cardioverter defibrillator (ICD) shocks in children and patients with congenital heart disease (CHD) remain a major complication of device therapy, occurring in as many as 50% of children with ICDs. New generation devices include algorithms designed to minimize inappropriate shocks. This study aimed to evaluate the effect of new generation ICDs on the incidence of inappropriate shocks in the pediatric and CHD population.

DESIGN

Retrospective study of patients with CHD or under age 25 receiving ICDs between 2000 and 2015. New generation ICDs were defined as those with Medtronic "SmartShock" algorithms.

RESULTS

Two hundred eight devices were implanted in 146 patients. Rates of inappropriate shocks were similar between diagnoses (P = .71). The rate of inappropriate shock was 15% over median 5.8 years follow-up. In the 36 patients (25%) with new generation ICDs, the rate of inappropriate shock was 6.3% over 4 years. Comparing old to new generation ICDs, freedom from first inappropriate shock was 90.6% versus 97.1% at 1 year and 80.4% versus 97.1% at 3 years (P = .01). Lead fracture was associated with having inappropriate shock (hazard ratio 8.5, P < .0001), and there was no significant difference between the device groups when lead fractures were excluded. Clinical actions were taken in 69% of patients after initial inappropriate shock (such as medication or program change, system revision, or explant). When an action was taken, subsequent inappropriate shock was reduced (5.3% vs 49.2% at 1 year; P = .002).

CONCLUSIONS

Pediatric and CHD patients are experiencing reduced inappropriate shocks with new generation ICD systems, though reduced lead fracture may account for this improvement. Clinical interventions after inappropriate shock favorably impact the subsequent rate of shocks once an inappropriate shock occurs.

Mindfulness-Based Stress Reduction and Group Support Decrease Stress in Adolescents with Cardiac Diagnoses: A Randomized Two-Group Study

Adolescents with cardiac diagnoses face unique challenges that can cause psychosocial distress. This study compares a Mindfulness-Based Stress Reduction (MBSR) program to a video online support group for adolescents with cardiac diagnoses. MBSR is a structured psycho-educational program which includes yoga, meditation, cognitive restructuring, and group support. A published feasibility study by our group showed significant reduction in anxiety following this intervention. Participants were randomized to MBSR or video online support group, and completed measures of anxiety, depression, illness-related stress, and coping pre- and post-6-session interventions. Qualitative data were obtained from post-intervention interviews. A total of 46 teens participated (mean 14.8 years; 63% female). Participants had congenital heart disease and/or cardiac device (52%), or postural orthostatic tachycardia syndrome (48%). Illness-related stress significantly decreased in both groups. Greater use of coping skills predicted lower levels of depression in both groups post-study completion. Higher baseline anxiety/depression scores predicted improved anxiety/depression scores in both groups. Each group reported the benefits of social support. The MBSR group further expressed benefits of learning specific techniques, strategies, and skills that they applied in real-life situations to relieve distress. Both the MBSR intervention and video support group were effective in reducing distress in this sample. Qualitative data elucidated the added benefits of using MBSR techniques to manage stress and symptoms. The video group format is useful for teens that cannot meet in person but can benefit from group support. Psychosocial interventions with stress management techniques and/or group support can reduce distress in adolescents with cardiac diagnoses.

How active are young cardiac device patients? Objective assessment of activity in children with cardiac devices

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.

Embodying a New Meaning of Being At Risk: Living With an Implantable Cardioverter Defibrillator for Arrhythmogenic Right Ventricular Cardiomyopathy

Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D) is a genetic condition that can cause fatal arrhythmias. The implantable cardioverter defibrillation (ICD) is a primary treatment for ARVC/D. Using a grounded theory approach, this study examines the experiences of 15 individuals living with an ICD. The ability to cope with and adjust to having an ICD is influenced by the acceptance of the ICD as something needed to survive, an understanding of the ICD's function, existing support networks, and ones' ability to manage everyday challenges. Coping well requires reshaping ideas about the meaning of being at risk and understanding how the ICD fits into that changing personal risk narrative. A thorough understanding of the unique needs of individuals with ARVC/D and of the specific factors contributing to the psychosocial distress related to having an ICD (vs. having the disease itself) is needed. Nurses must be prepared to provide ongoing support and education to this population.

“There are days I wish it wasn’t there, and there’s days I realize I’m lucky”: A qualitative study of psychological sequelae to the implantable cardioverter defibrillator as a treatment for the prevention of sudden cardiac death in arrhythmogenic right ventricular cardiomyopathy

Objectives

Arrhythmogenic right ventricular cardiomyopathy caused by a TMEM43 p.S358L mutation is a fully penetrant autosomal dominant cause of sudden cardiac death where prophylactic implantable cardioverter defibrillator therapy significantly reduces mortality by returning lethal cardiac rhythms to normal. This qualitative study assessed the psychological ramifications of the implantable cardioverter defibrillator on recipients, their spouses and their mutation negative siblings.

Design

Qualitative interview study.

Participants

Twenty-one individuals (nine mutation positive, eight mutation negative and four spouses) from 15 families completed semi-structured interviews.

Results

No theoretical assumptions about the data were made: inductive sub-coding was accomplished with the constant comparison method and cohesive themes across all respondent interviews were determined. All interviewees had a family history of sudden cardiac death and appropriate implantable cardioverter defibrillator therapy in themselves or family members. Average length of time with an implantable cardioverter defibrillator was 10 years. Major themes included: (1) acceptance and gratitude, (2) grudging acceptance, (3) psychological effects (on emotional and psychological well-being; functioning of the broader family unit; and relationships), and (4) practical concerns (on clothes, travel, loss of driving licence and the effects of an implantable cardioverter defibrillator discharge). These affected all family members, regardless of mutation status.

Conclusions

Despite the survival advantage of implantable cardioverter defibrillator therapy, the intervention carries psychological and practical burdens for family members from kindreds manifesting p.S358L TMEM43 ARVC that does not appear to dissipate with time. A move towards integrating psychology services with the cardiac genetics clinic for the extended family may provide benefit.

Behavioural and emotional implications of implantable cardioverter-defibrillators in the young and in athletes

Despite the life-saving capabilities of implantable cardioverter-defibrillators, they may have implications on behavioural and emotional well-being and have been shown to negatively affect patients' psychosocial functioning. Children and CHD patients with these devices are at higher risk for complications, and therefore may have higher risk of psychosocial dysfunction including depression, anxiety, and a decrease in overall quality of life. In addition, these patients may be restricted from activities, which may also contribute to psychosocial dysfunction. Recommendations published in 2015 support a more liberal approach to athletic participation in this patient population compared with previous guidelines. Approaches to limit psychosocial dysfunction include education, minimisation of shocks, and psychosocial therapy. Psychosocial dysfunction should be assessed at each clinic visit, and information regarding intervention should be provided to patients and their families as needed. Psychosocial dysfunction may be debilitating, and healthcare providers should facilitate and support normal psychosocial function by offering resources as needed.

The Impact on Family of Pediatric Chronic Respiratory Failure in the Home

OBJECTIVE

To assess the family impact of managing severe, chronic respiratory failure (CRF) at home. Better understanding will inform parental counseling and serve as a point of reference for interventions.

STUDY DESIGN

Families of children with CRF completed the Impact on Family Scale (IFS) and Consumer Assessment of Healthcare Providers and Systems. Using multivariable linear regression, we assessed the relationship between IFS and family, clinical, and utilization characteristics.

RESULTS

A total of 118 parents (60%) completed the IFS; 114 parents (58%) completed all measures. The 15-item IFS mean total score was 40 (SD = 10) with a possible range of 15-60 (greater scores indicate more impact). Modeling identified a negative association with parent emotional functioning, parent-rated child health, and private insurance only (compared with both private/public), and other family characteristics (eg, parental education, marital status, and income) were not associated with IFS scores.

CONCLUSION

Families of children with CRF are greatly impacted by their child's health. In contrast to other children with special health care needs, family characteristics were not associated with IFS scores, excluding insurance type. These results may reflect more uniform demands and stressors related to CRF. Future research should identify interventions to attenuate the impact of CRF.

Quality of life after videoscopic left cardiac sympathetic denervation in patients with potentially life-threatening cardiac channelopathies/cardiomyopathies

BACKGROUND

Left cardiac sympathetic denervation (LCSD) provides an additive or potentially alternative treatment option for patients with life-threatening cardiac channelopathies/cardiomyopathies.

OBJECTIVE

We sought to examine the effects of LCSD on quality of life (QOL).

METHODS

From November 2005 to May 2013, 109 patients who underwent LCSD were subsequently sent postoperative QOL surveys.

RESULTS

Of 109 patients, 8 (7%) could not be contacted. Of the remaining 101 patients, 62 returned surveys (response rate 61%). There were an average of 4.1 ± 1.8 self-reported side effects immediately after LCSD. The most common anticipated side effects included unilateral hand dryness, color or temperature variance between sides of the face, and abnormal sweating. Although parent-reported pediatric physical QOL scores were lower than national norms, there were no differences in psychosocial QOL or disability scores (P = .09 and .33, respectively). QOL scores for adult patients were not significantly different from a US normative sample. Adult LCSD patients reported less disability than a US normative sample (P < .01). There was no correlation between QOL scores and the presence of anticipated side effects. However, among the subset of pediatric patients who continued to receive ventricular fibrillation-terminating implantable cardioverter-defibrillator shocks after LCSD, there was a correlation between their disability scores and the number of reported shocks (Spearman correlation = 0.56). The majority of patients/parents reported that they were very or somewhat satisfied with their surgery (or their child's surgery) and would definitely or probably recommend LCSD to another patient.

CONCLUSION

Despite the anticipated side effects associated with LCSD, patients are satisfied with their surgery and indicate that they would recommend the surgery to another patient.

Implantable cardioverter-defibrillators in children

Implantable cardioverter-defibrillators (ICD) have become an integral component in the management of children with life-threatening cardiac arrhythmias complicating a variety of different inherited and congenital cardiovascular conditions. Implantation often requires novel approaches and configurations to overcome the size and anatomic limitations posed by many children needing ICDs. While their use has undoubtedly saved many lives, ICD use may be associated with significant morbidity, so detailed case selection and individualised postimplant programming is critical.

Time dependence of risks and benefits in pediatric primary prevention implantable cardioverter-defibrillator therapy

BACKGROUND

Implantable cardioverter defibrillators (ICDs) used to prevent sudden cardiac arrest in children not only provide appropriate therapy in 25% of patients but also result in a significant incidence of inappropriate shocks and other device complications. ICDs placed for secondary prevention have higher rates of appropriate therapy than those placed for primary prevention. Pediatric patients with primary prevention ICDs were studied to determine time-dependent incidence of appropriate use and adverse events.

METHODS AND RESULTS

A total of 140 patients aged <21 years (median age, 15 years) at first ICD implantation at Boston Children's Hospital (2000-2009) in whom devices were placed for primary prevention were retrospectively identified. Demographics and times to first appropriate shock; adverse events (including inappropriate shock, lead failure, reintervention, and complication); generator replacement and follow-up were noted. During mean follow-up of 4 years, appropriate shock occurred in 19% patients and first adverse event (excluding death/transplant) occurred in 36%. Risk of death or transplant was ≈1% per year and was not related to receiving appropriate therapy. Conditional survival analysis showed rates of appropriate therapy and adverse events decrease soon after implantation, but adverse events are more frequent than appropriate therapy throughout follow-up.

CONCLUSIONS

Primary prevention ICDs were associated with appropriate therapy in 19% and adverse event in 36% in this cohort. The incidence of both first appropriate therapy and device-related adverse events decreased during longer periods of follow-up after implantation. This suggests that indications for continued device therapy in pediatric primary prevention ICD patients might be reconsidered after a period of nonuse.
