Management errors in adults with congenital heart disease: prevalence, sources, and consequences

Access to Specialized Care Across the Lifespan in Tetralogy of Fallot

Individuals living with tetralogy of Fallot require lifelong specialized congenital heart disease care to monitor for and manage potential late complications. However, access to cardiology care remains a challenge for many patients, as does access to mental health services, dental care, obstetrical care, and other specialties required by this population. Inequities in health care access were highlighted by the COVID-19 pandemic and continue to exist. Paradoxically, many social factors influence an individual's need for care, yet inadvertently restrict access to it. These include sex and gender, being a member of a racial or ethnic historically excluded group, lower educational attainment, lower socioeconomic status, living remotely from tertiary care centres, transportation difficulties, inadequate health insurance, occupational instability, and prior experiences with discrimination in the health care setting. These factors may coexist and have compounding effects. In addition, many patients believe that they are cured and unaware of the need for specialized follow-up. For these reasons, lapses in care are common, particularly around the time of transfer from paediatric to adult care. The lack of trained health care professionals for adults with congenital heart disease presents an additional barrier, even in higher income countries. This review summarizes challenges regarding access to multiple domains of specialized care for individuals with tetralogy of Fallot, with a focus on the impact of social determinants of health. Specific recommendations to improve access to care within Canadian and American systems are offered.

An Opportunity to See the Heart Defect Physically: Medical Student Experiences of Technology-Enhanced Learning with 3D Printed Models of Congenital Heart Disease

Three-dimensional (3D) printing is increasingly used in medical education and paediatric cardiology. A technology-enhanced learning (TEL) module was designed to accompany 3D printed models of congenital heart disease (CHD) to aid in the teaching of medical students. There are few studies evaluating the attitudes and perceptions of medical students regarding their experience of learning about CHD using 3D printing. This study aimed to explore senior medical students' experiences in learning about paediatric cardiology through a workshop involving 3D printed models of CHD supported by TEL in the form of online case-based learning. A mixed-methods evaluation was undertaken involving a post-workshop questionnaire (n = 94 students), and focus groups (n = 16 students). Focus group and free-text questionnaire responses underwent thematic analysis. Questionnaire responses demonstrated widespread user satisfaction; 91 (97%) students agreed that the workshop was a valuable experience. The highest-level satisfaction was for the physical 3D printed models, the clinical case-based learning, and opportunity for peer collaboration. Thematic analysis identified five key themes: a variable experience of prior learning, interplay between physical and online models, flexible and novel workshop structure, workshop supported the learning outcomes, and future opportunities for learning using 3D printing. A key novel finding was that students indicated the module increased their confidence to teach others about CHD and recommended expansion to other parts of the curriculum. 3D printed models of CHD are a valuable learning resource and contribute to the richness and enjoyment of medical student learning, with widespread satisfaction.

Adults with small, unrepaired atrial septal defects have reduced cardiac index during exercise

OBJECTIVES

Small, unrepaired atrial septal defects are considered a benign lesion with good prognosis. Recently, clinical and register-based studies discovered increased long-term mortality and morbidity. The nature of these findings is not fully understood. Therefore, MRI was performed to evaluate cardiac function at rest and during exercise.

METHODS

Adults with open or spontaneously closed atrial septal defects and healthy, matched controls underwent MRI for evaluation of cardiac chamber volume. Quantitative flow scans measured blood flow in the ascending aorta and the proximal pulmonary artery at rest and during increasing supine exercise.

RESULTS

In total, 15 open defects (39 ± 11 years) and 15 matched controls (38 ± 12 years) were included, along with 20 spontaneously closed (36 ± 13 years) and 20 controls (36 ± 11 years). Cardiac chamber volumes and flow measurements at rest were comparable between groups, as were heart rates and workloads during exercise. At maximal exercise, open defects reached 31% lower cardiac index and had 38% higher retrograde flow in the pulmonary artery than their controls, p < 0.01. Shunt ratio remained unchanged during exercise, 1.2 ± 0.2. Closed defects reached 18% lower cardiac index, p = 0.02, with comparable pulmonary retrograde flow. Maximal cardiac index was inversely correlated with increasing age for patients only.

CONCLUSION

Adults with a small, open or spontaneously closed atrial septal defects exhibit markedly lower exercise capacity compared with healthy peers. Moreover, open defects exhibit higher retrograde flows with increasing exercise. Finally, increasing age is related to poorer results in patients but not healthy controls. Longitudinal studies are necessary in order to determine potential accelerated worsening of physical capacity along with age-related changes in patients.

Common diagnostic errors in adults with congenital heart disease

Owing to the great advances in the care for children with congenital heart disease by paediatric cardiac surgeons and cardiologists, there are ever increasing numbers of patients with congenital heart disease who reach adult life. At some stage during the late teenage years or soon after, these patients 'transition' from paediatric cardiac care to surveillance by cardiologists who look after adults. Many such specialists, however, are more familiar with commoner acquired heart problems such as coronary disease, heart failure, and arrhythmia in structurally normal hearts and less familiar with congenital heart disease. For this reason, international guidelines have suggested that the care of young adults with congenital heart disease take place in designated specialist adult congenital heart disease centres. It remains very important, however, for general cardiologists to have a good understanding of many aspects of adult congenital heart disease, including common pitfalls to avoid and, importantly, when to refer on, to a specialist centre. To help healthcare providers across the spectrum of cardiology practice to address common themes in adult congenital heart disease, this state-of-the-art review provides a series of case vignettes to illustrate frequent diagnostic problems that we have seen in our tertiary-level adult congenital heart disease centres, which are sometimes encountered in general cardiology settings. These include commonly 'missed' diagnoses, or errors with diagnosis or management, in these often very complex patients.

Factors Associated With Nonattendance at the Adult Congenital Heart Disease Clinic

Adults with congenital heart disease (CHD) are a complex population for whom adult CHD-specific care results in better outcomes. Our objective was to identify factors associated with no-shows and cancelations in an adult CHD (ACHD) clinic and evaluate the efficacy of a social worker intervention to promote ambulatory follow-up. The medical record identified adults with a scheduled appointment in the adult CHD clinic from January 2017 to March 2021. Social worker intervention was performed between March 2020 and May 2021 and consisted of phone calls to those who did not show up. Logistic regression and descriptive statistics were performed. Of 8,431 scheduled visits, 56.7% were completed, 4.6% were no-shows, and 17.5% were canceled by patients. The factors associated with no-shows were Medicaid (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.26 to 2.12, p <0.001), previous no-show (OR per 1% increase in previous no-show rate 1.13, 95% CI 1.12 to 1.15, p <0.001), satellite clinic location (OR 3.15, 95% CI 2.06 to 4.74, p <0.001), virtual visit (OR 1.97, 95% CI 1.28 to 2.92, p = 0.001), and Hispanic ethnicity (OR 1.48, 95% CI 1.03 to 2.10, p = 0.031). The factors associated with cancelations were female gender (OR 1.45, 95% CI 1.25 to 1.68, p <0.001) and virtual visits (OR 2.24, 95% CI 1.50 to 3.40, p <0.001). Social worker outreach calls did not impact frequency of rescheduling. No patients accepted additional support. In conclusion, Medicaid insurance, previous number of no-shows, and Hispanic ethnicity were found to be associated with a higher risk of no-show, identifying a high-risk population that may benefit from targeted interventions. Social worker outreach did not have an appreciable impact on the rescheduling rates.

Cardiogenic shock in adults with congenital heart disease: Insights from the FRENSHOCK registry

BACKGROUND

Data on cardiogenic shock in adults with congenital heart disease (ACHD) are scarce.

AIM

We sought to describe cardiogenic shock in ACHD patients in a nationwide cardiogenic shock registry.

METHODS

From the multicentric FRENSHOCK registry (772 patients with cardiogenic shock from 49 French centres between April and October 2016), ACHD patients were compared with adults without congenital heart disease (non-ACHD). The primary outcome was defined by all-cause mortality, chronic ventricular assist device or heart transplantation at 1year.

RESULTS

Out of the 772 patients, seven (0.9%) were ACHD, who were younger (median age: 56 vs. 67years), had fewer cardiovascular risk factors, such as hypertension (14.3% vs. 47.5%) and diabetes (14.3% vs. 28.3%), and no previous ischaemic cardiopathy (0 vs. 61.5%). Right heart catheterization (57.1% vs. 15.4%), pacemakers (28.6% vs. 4.6%) and implantable cardioverter-defibrillators (28.6% vs. 4.8%) were indicated more frequently in the management of ACHD patients compared with non-ACHD patients, whereas temporary mechanical circulatory support (0 vs. 18.7%) and invasive mechanical ventilation (14.3% vs. 38.1%) were less likely to be used in ACHD patients. At 1year, the primary outcome occurred in 85.7% (95% confidence interval: 42.1-99.6) ACHD patients and 52.3% (95% confidence interval: 48.7-55.9) non-ACHD patients. Although 1-year mortality was not significantly different between ACHD patients (42.9%) and non-ACHD patients (45.4%), ventricular assist devices and heart transplantation tended to be more frequent in the ACHD group.

CONCLUSIONS

Cardiogenic shock in ACHD patients is rare, accounting for only 0.9% of an unselected cardiogenic shock population. Despite being younger and having fewer co-morbidities, the prognosis of ACHD patients with cardiogenic shock remains severe, and is similar to that of other patients.

Changes in the Cath Lab in the Treatment of Adult Patients with Congenital Heart Disease: A 12-Year Experience in a Single Referral Center with the Establishment of a Dedicated Working Group

BACKGROUND

Adults with congenital heart disease (ACHD) are a growing population needing ongoing care. The aim of this study was to investigate if a dedicated ACHD team impacted the timing and indication of invasive cardiology procedures in these patients at our hospital.

METHODS

Our retrospective single-center study enrolled adult patients with moderate or complex congenital heart disease and with at least one cardiac catheterization between January 2010 and December 2021. According to the period, procedures were labeled as group A (2010 to 2015) or group B (2016 to 2021) and further divided into diagnostic (DCC) and interventional cardiac catheterizations (ICC).

RESULTS

594 patients were eligible for the study. Both DCC (p < 0.05) and ICC increased between groups A and B (p < 0.05). In group B: Fontan patients accounted for the majority of DCC (p < 0.001), while DCC decreased in arterial switch repair (p < 0.001). In Fontan patients, conduit stenting was prevalent (p < 0.001), while fenestration closures dropped (p < 0.01). In patients with tetralogy of Fallot and native outflow tract, percutaneous pulmonary valve implantations (PPVI) increased, with a concurrent reduction in pulmonary valve replacements (p < 0.001 vs. surgical series). In right ventricular conduits, ICC increased (p < 0.01), mainly due to PPVI. Among Mustard/Senning patients, baffle stenting increased from Group A to Group B (p < 0.001). In patients with pulmonary atresia and biventricular repair, ICC often increased for pulmonary artery stenting.

CONCLUSIONS

A dedicated working group could improve ACHD patients' indications for interventional procedures, leading to tailored treatment, better risk stratification and optimizing time until heart transplantation.

An interactive geographic information system to inform optimal locations for healthcare services

Large health datasets can provide evidence for the equitable allocation of healthcare resources and access to care. Geographic information systems (GIS) can help to present this data in a useful way, aiding in health service delivery. An interactive GIS was developed for the adult congenital heart disease service (ACHD) in New South Wales, Australia to demonstrate its feasibility for health service planning. Datasets describing geographic boundaries, area-level demographics, hospital driving times, and the current ACHD patient population were collected, linked, and displayed in an interactive clinic planning tool. The current ACHD service locations were mapped, and tools to compare current and potential locations were provided. Three locations for new clinics in rural areas were selected to demonstrate the application. Introducing new clinics changed the number of rural patients within a 1-hour drive of their nearest clinic from 44·38% to 55.07% (79 patients) and reduced the average driving time from rural areas to the nearest clinic from 2·4 hours to 1·8 hours. The longest driving time was changed from 10·9 hours to 8·9 hours. A de-identified public version of the GIS clinic planning tool is deployed at https://cbdrh.shinyapps.io/ACHD_Dashboard/. This application demonstrates how a freely available and interactive GIS can be used to aid in health service planning. In the context of ACHD, GIS research has shown that adherence to best practice care is impacted by patients' accessibility to specialist services. This project builds on this research by providing opensource tools to build more accessible healthcare services.

Evolution in Congenital Cardiology Education: The Rise of Digital-Learning Tools

Technology-enhanced learning is now an established part of medical education due to its ready availability and on-demand nature. This offers new opportunities but also challenges to both learners and teachers. This review outlines the current use of social media tools and online resources in medical education with a particular emphasis on congenital cardiology. It provides strategies to the reader on how to optimize learning in the digital environment and offers guidance on how such tools can be incorporated into routine educational practice. Suggestions for developing and assessing educational material online are discussed. Lastly, the concepts of digital professionalism and digital scholarship are explored to aid medical teachers and educators employ these technologies effectively into their teaching and career development.

Changing epidemiology of congenital heart disease: effect on outcomes and quality of care in adults

The epidemiology of congenital heart disease (CHD) has changed in the past 50 years as a result of an increase in the prevalence and survival rate of CHD. In particular, mortality in patients with CHD has changed dramatically since the latter half of the twentieth century as a result of more timely diagnosis and the development of interventions for CHD that have prolonged life. As patients with CHD age, the disease burden shifts away from the heart and towards acquired cardiovascular and systemic complications. The societal costs of CHD are high, not just in terms of health-care utilization but also with regards to quality of life. Lifespan disease trajectories for populations with a high disease burden that is measured over prolonged time periods are becoming increasingly important to define long-term outcomes that can be improved. Quality improvement initiatives, including advanced physician training for adult CHD in the past 10 years, have begun to improve disease outcomes. As we seek to transform lifespan into healthspan, research efforts need to incorporate big data to allow high-value, patient-centred and artificial intelligence-enabled delivery of care. Such efforts will facilitate improved access to health care in remote areas and inform the horizontal integration of services needed to manage CHD for the prolonged duration of survival among adult patients.

Caring for the Aging Patient With Adult Congenital Heart Disease: A Review of Cardiac and Noncardiac Comorbidities

As the demographics of congenital heart disease (CHD) have shifted, there are now more adults living with CHD than children in North America. This presents unprecedented challenges as patients with CHD acquire noncardiac comorbidities and seek care for a variety of reasons, including noncardiac surgery and emergency department (ED) visits. CHD shifts from a one organ problem to a multisystem disease and requires a team of specialists to maintain high-quality longitudinal care. In this review, we summarize the challenges patients with CHD and their providers face as they age. We review the demographics of CHD and health care utilization. We examine the rates of noncardiac comorbidities and the current quality of care received by adult patients with CHD.

Disparities in Loss to Follow-Up Among Adults With Congenital Heart Disease in North Carolina

Background

The AHA/ACC Adult Congenital Heart Disease guidelines recommend that most adults with congenital heart disease (CHD) follow-up with CHD cardiologists every 1 to 2 years because longer gaps in care are associated with adverse outcomes. This study aimed to determine the proportion of patients in North Carolina who did not have recommended follow-up and to explore predictors of loss to follow-up.

Methods

Patients ages ≥18 years with a healthcare encounter from 2008 to 2013 in a statewide North Carolina database with an ICD-9 code for CHD were assessed. The proportion with cardiology follow-up within 24 months following index encounter was assessed with Kaplan-Meier estimates. Cox regression was utilized to identify demographic factors associated with differences in follow-up.

Results

2822 patients were identified. Median age was 35 years; 55% were female. 70% were white, 22% black, and 3% Hispanic; 36% had severe CHD. The proportion with 2-year cardiology follow-up was 61%. Those with severe CHD were more likely to have timely follow-up than those with less severe CHD (72% vs 55%, P < .01). Black patients had a lower likelihood of follow-up than white patients (56% vs 64%, P = .01). Multivariable Cox regression identified younger age, non-severe CHD, and non-white race as risk factors for a lower likelihood of follow-up by 2 years.

Conclusion

39% of adults with CHD in North Carolina are not meeting AHA/ACC recommendations for follow-up. Younger and minority patients and those with non-severe CHD were particularly vulnerable to inadequate follow-up; targeted efforts to retain these patients in care may be helpful.

Impact of a structured patient education programme on early diagnosis of prosthetic pulmonary valve endocarditis

BACKGROUND

Infective endocarditis is a major threat after prosthetic pulmonary valve replacement. Early diagnosis may improve outcomes.

METHODS

A structured patient education programme for prevention and early diagnosis of infective endocarditis was developed at our institution since 2016. Time delay between onset of symptoms of prosthetic pulmonary valve endocarditis and its diagnosis (defined as initiation of appropriate high-dose intravenous antibiotic treatment) was compared for patients presenting before (cohort 1) and after (cohort 2) initiation of the patient education programme.

RESULTS

Between 2008-2019, 26 patients (median age 24.9, range: 16.8-62.0 years, 73% male) were diagnosed with prosthetic pulmonary valve endocarditis, 13 patients (cohort 1) before (1.7 cases/year) and 13 patients (cohort 2) after June 2016 (3.7 cases/year). There were no differences in baseline characteristics or clinical presentation between the study cohorts. Overall, the median delay between onset of symptoms and diagnosis of infective endocarditis was 6 days (range: 0-133 days) with a significantly longer delay among patients in cohort 1, compared to cohort 2 (25 days, range: 5-133 days versus 3 days, range: 0-13 days, p < 0.0001). A delay of >7 days was documented in 11/13 patients (85%) in cohort 1 as compared to 1/13 (8%) in cohort 2 (p < 0.001). Need for urgent valve replacement or permanent deterioration of prosthetic valve function was higher in cohort 1, compared to cohort 2 (11/13, 85% versus 5/13, 39%; p = 0.041).

CONCLUSIONS

Prosthetic pulmonary valve endocarditis is increasingly recognised. A structured patient education programme may improve early diagnosis and clinical outcomes.

Medical education and training within congenital cardiology: current global status and future directions in a post COVID-19 world

Despite enormous strides in our field with respect to patient care, there has been surprisingly limited dialogue on how to train and educate the next generation of congenital cardiologists. This paper reviews the current status of training and evolving developments in medical education pertinent to congenital cardiology. The adoption of competency-based medical education has been lauded as a robust framework for contemporary medical education over the last two decades. However, inconsistencies in frameworks across different jurisdictions remain, and bridging gaps between competency frameworks and clinical practice has proved challenging. Entrustable professional activities have been proposed as a solution, but integration of such activities into busy clinical cardiology practices will present its own challenges. Consequently, this pivot towards a more structured approach to medical education necessitates the widespread availability of appropriately trained medical educationalists, a development that will better inform curriculum development, instructional design, and assessment. Differentiation between superficial and deep learning, the vital role of rich formative feedback and coaching, should guide our trainees to become self-regulated learners, capable of critical reasoning yet retaining an awareness of uncertainty and ambiguity. Furthermore, disruptive innovations such as "technology enhanced learning" may be leveraged to improve education, especially for trainees from low- and middle-income countries. Each of these initiatives will require resources, widespread advocacy and raised awareness, and publication of supporting data, and so it is especially gratifying that Cardiology in the Young has fostered a progressive approach, agreeing to publish one or two articles in each journal issue in this domain.

Identifying and responding to the sexual reproductive health needs of women with heart disease: A qualitative study

Background:

Recognizing the needs of women with heart disease in the field of reproductive health and meeting them can reduce the related complications. The aim of this study was to identify the sexual and reproductive health needs of these women.

Materials and Methods:

The present study was conducted with qualitative approach (Content analysis). Ten married women of reproductive age with heart disease and 20 providers and managers in, Isfahan, Iran, were selected by using purposive and snowball methods (in 2020). The research setting included heart disease clinics, offices of health team, comprehensive health centers, and the Isfahan Maternal Health Department. Data were collected by semi-structured individual face-to-face interviews in the clinic or other appropriate locations. Some interviews were conducted virtually. Analysis was performed by Qualitative contentment analysis / Conventional content analysis.

Results:

Sexual and reproductive health needs of women with heart disease were emerged in five main categories, “planned childbearing,” “ssociocultural support,” “Early reproductive health care of girls,” “health team attention to sexual health,” and “health system revision.”

Conclusions:

Providing comprehensive reproductive health services before and during pregnancy, family planning, and sexual health for women with heart disease is necessary. It seems that using a multidisciplinary team approach could improve their reproductive health.

Discontinuation of follow-up care for young people with complex chronic conditions: conceptual definitions and operational components

Background

A substantial proportion of young people with Complex Chronic Conditions (CCCs) experience some degree of discontinuation of follow-up care, which is an umbrella term to describe a broken chain of follow-up. Discontinuation of follow-up care is not clearly defined, and the great plethora of terms used within this field cannot go unnoticed. Terms such as “lost to follow-up”, “lapses in care” and “care gaps”, are frequently used in published literature, but differences between terms are unclear. Lack of uniformity greatly affects comparability of study findings. The aims of the present study were to (i) provide a systematic overview of terms and definitions used in literature describing discontinuation of follow-up care in young people with CCC’s; (ii) to clarify operational components of discontinuation of follow-up care (iii); to develop conceptual definitions and suggested terms to be used; and (iv) to perform an expert-based evaluation of terms and conceptual definitions.

Methods

A systematic literature search performed in PubMed was used to provide an overview of current terms used in literature. Using a modified summative content analysis, operational components were analysed, and conceptual definitions were developed. These conceptual definitions were assessed by an expert panel using a survey.

Results

In total, 47 terms and definitions were retrieved, and a core set of operational components was identified. Three main types of discontinuation of follow-up care emerged from the analysis and expert evaluation, conceptually defined as follows: Lost to follow-up care: “No visit within a defined time period and within a defined context, and the patient is currently no longer engaged in follow-up care”;Gap in follow-up care: “Exceeded time interval between clinic visits within a defined context, and the patient is currently engaged in follow-up care”; andUntraceability: “Failure to make contact due to lack of contact information”.

Conclusion

By creating a common vocabulary for discontinuation of follow-up care, the quality of future studies could improve. The conceptual definitions and operational components provide guidance to both researchers and healthcare professionals focusing on discontinuation of follow-up care for young people with CCCs.

Qualitative study of facilitators and barriers for continued follow-up care as perceived and experienced by young people with congenital heart disease in Sweden

In-depth understanding of factors perceived by young people with congenital heart disease (CHD) to affect continued follow-up care is needed to tailor preventive strategies for discontinuation of follow-up care. To identify facilitating factors, low-prevalence settings in terms of discontinuation should be investigated.

OBJECTIVE

This qualitative study describes factors affecting continued follow-up as perceived and experienced by young adults with CHD.

PARTICIPANTS

Using a mixed purposive sampling technique, 16 young adults with CHD were included. Three participants had discontinued follow-up care and 13 had continued follow-up care after transfer.

SETTING

Participants were recruited from all seven university hospitals in Sweden, which is considered a low-prevalence setting in terms of discontinuation.

DESIGN

Individual interviews were performed and subjected to qualitative content analysis.

RESULTS

The analysis resulted in three main categories, illuminating factors affecting continued follow-up: (1) motivation for follow-up care; (2) participation in care and sense of connectedness with healthcare provider (HCP) and (3) care accessibility. The choice of continuing follow-up or not was multifactorial. Knowledge of your CHD and the importance of continuing follow-up care was a central factor, as well as experiencing CHD-related symptoms and having ongoing or planned medical treatment or interventions. Sensing a clear purpose with follow-up care was facilitating, as was feeling well treated and cared for by HCPs. Practical aspects, such as travel distance was also stressed, as well as active invitations and reminders for visits.

CONCLUSION

Factors on both patient, hospital and healthcare system level were raised by participants, stressing the importance of holistic approaches when developing preventive strategies for discontinuation. There is a need for improved skills and competencies among HCPs, as well as a person-centred approach to follow-up care. In addition, specific healthcare needs and remaining transitional needs after transfer to adult care require careful consideration to prevent discontinuation.

Adäquate Versorgungsstrukturen und Bedeutung von Big-Data-Analysen bei EMAH-Patienten

Da immer mehr Kinder mit angeborenem Herzfehler (AHF) überleben und ins Erwachsenenalter eintreten, sind nunmehr rund zwei Drittel der aktuellen AHF-Patienten Erwachsene mit angeborenen Herzfehlern (EMAH). Es wird geschätzt, dass in Deutschland aktuell ca. 350000 EMAH-Patienten leben, wobei die Zahl weiter rasch zunimmt. Die lebenslange kardiologische Anbindung von EMAH-Patienten ist nach aktuellen Leitlinienempfehlungen erforderlich und mit einer niedrigeren Letalität und Morbidität assoziiert. Somit ist die ausschließliche hausärztliche Versorgung von EMAH-Patienten nicht ausreichend. EMAH-Patienten sind an spezialisierte EMAH-Zentren/bei EMAH-Kardiologen anzubinden und sollten gemeinschaftlich mit niedergelassenen kardiologischen Kollegen behandelt werden. Big Data und Methoden des maschinellen Lernens sind integraler Bestandteil der Forschungsbemühungen bei EMAH-Patienten, die unter einer chronischen, lebenslangen Erkrankung leiden. Methoden der künstlichen Intelligenz werden die Versorgung von EMAH-Patienten in Zukunft effizienter machen und die Reproduzierbarkeit von Bildgebungsuntersuchungen erhöhen.

A reproductive and sexual health promotion program for women with heart diseases: A protocol for mixed methods study

BACKGROUND

Nowadays, for various reasons, the prevalence of heart diseases has increased in women during reproductive age. These diseases can lead to serious reproductive and sexual-related complications in the affected women. This study will conduct to develop a reproductive health promotion program for women with heart diseases.

MATERIALS AND METHODS

This is an exploratory sequential mixed methods study that will be conducted in four phases. The first phase is a qualitative research that is done using content analysis method and semi-structured individual interviews. The experiences of women with heart disease and health providers' team in educational hospitals, health centers, and private offices of physicians about reproductive health need will be explored. Purposive sampling will be continued until data saturation is reached and the conventional content analysis method will be used. In the second phase, the studies published from 2000 to 2020 will be reviewed by the matrix method and then will be analyzed by using thematic analysis. Integrating the results of these two stages, the draft of the program will be designed. In the third phase, the validation of the program will be checked by using the two-round modified Delphi method. In the fourth phase, the program will be implemented by the health system and its process will be monitored.

CONCLUSION

A life cycle reproductive health program for women with heart disease can help improve their preconception health, fertility planning, and sexual health and promote the well-being of these women in the long run.

Atrial septal defect in adulthood: a new paradigm for congenital heart disease

Atrial septal defects (ASDs) represent the most common congenital heart defect diagnosed in adulthood. Although considered a simple defect, challenges in optimal diagnostic and treatment options still exist due to great heterogeneity in terms of anatomy and time-related complications primarily arrhythmias, thromboembolism, right heart failure and, in a subset of patients, pulmonary arterial hypertension (PAH). Atrial septal defects call for tertiary expertise where all options may be considered, namely catheter vs. surgical closure, consideration of pre-closure ablation for patients with atrial tachycardia and suitability for closure or/and targeted therapy for patients with PAH. This review serves to update the clinician on the latest evidence, the nuances of optimal diagnostics, treatment options, and long-term follow-up care for patients with an ASD.

Study design and rationale of the pAtients pResenTing with cOngenital heaRt dIseAse Register (ARTORIA-R)

Aim

Due to improved therapy in childhood, many patients with congenital heart disease reach adulthood and are termed adults with congenital heart disease (ACHD). ACHD often develop heart failure (HF) as a consequence of initial palliative surgery or complex anatomy and subsequently require advanced HF therapy. ACHD are usually excluded from trials evaluating heart failure therapies, and in this context, more data about heart failure trajectories in ACHD are needed to guide the management of ACHD suffering from HF.

Methods and results

The pAtients pResenTing with cOngenital heaRt dIseAse Register (ARTORIA‐R) will collect data from ACHD evaluated or listed for heart or heart‐combined organ transplantation from 16 countries in Europe and the Asia/Pacific region. We plan retrospective collection of data from 1989–2020 and will include patients prospectively. Additional organizations and hospitals in charge of transplantation of ACHD will be asked in the future to contribute data to the register. The primary outcome is the combined endpoint of delisting due to clinical worsening or death on the waiting list. The secondary outcome is delisting due to clinical improvement while on the waiting list. All‐cause mortality following transplantation will also be assessed. The data will be entered into an electronic database with access to the investigators participating in the register. All variables of the register reflect key components important for listing of the patients or assessing current HF treatment.

Conclusion

The ARTORIA‐R will provide robust information on current management and outcomes of adults with congenital heart disease suffering from advanced heart failure.

Different levels of care for follow-up of adults with congenital heart disease: a cost analysis scrutinizing the impact on medical costs, hospitalizations, and emergency department visits

AIM

To scrutinize the economic impact of different care levels, such as shared care, in the follow-up of adult congenital heart disease (ACHD) patients.

METHODS

The BELgian COngenital heart disease Database combining Administrative and Clinical data (BELCODAC) was analyzed. Patients (N = 6579) were categorized into five care levels based on their cardiac follow-up pattern between 2006 and 2010. Medical costs, hospitalizations, and emergency department visits were measured between 2011 and 2015.

RESULTS

In patients with moderate lesions, highly specialized cardiac care (HSC; exclusive follow-up by ACHD specialists) and shared care with predominantly specialized cardiac care (SC+) were associated with significantly lower medical costs and resource use compared to shared care with predominantly general cardiac care (SC-) and general cardiac care (GCC). In the patient population with mild lesions, HSC was associated with better economic outcomes than SC- and GCC, but SC+ was not. HSC was associated with fewer hospitalizations (- 33%) and less pharmaceutical costs (- 46.3%) compared to SC+. Patients with mild and moderate lesions in the no cardiac care (NCC) group had better economic outcomes than those in the GCC and SC- groups, but post-hoc analysis revealed that they had a different patient profile than patients under cardiac care.

CONCLUSION

More specialized care levels are associated with better economic outcomes in patients with mild or moderate lesions in cardiac follow-up. Shared care with strong involvement of ACHD specialists might be a management option to consider. Characteristics of patients without cardiac follow-up but good medium-term economic prospects should be further scrutinized.

Lack of specialist care is associated with increased morbidity and mortality in adult congenital heart disease: a population-based study

AIMS

The aim of this study was to provide population-based data on the healthcare provision for adults with congenital heart disease (ACHD) and the impact of cardiology care on morbidity and mortality in this vulnerable population.

METHODS AND RESULTS

Based on administrative data from one of the largest German Health Insurance Companies, all insured ACHD patients (<70 years of age) were included. Patients were stratified into those followed exclusively by primary care physicians (PCPs) and those with additional cardiology follow-up between 2014 and 2016. Associations between level of care and outcome were assessed by multivariable/propensity score Cox analyses. Overall, 24 139 patients (median age 43 years, 54.8% female) were included. Of these, only 49.7% had cardiology follow-up during the 3-year period, with 49.2% of patients only being cared for by PCPs and 1.1% having no contact with either. After comprehensive multivariable and propensity score adjustment, ACHD patients under cardiology follow-up had a significantly lower risk of death [hazard ratio (HR) 0.81, 95% confidence interval (CI) 0.67-0.98; P = 0.03) or major events (HR 0.85, 95% CI 0.78-0.92; P < 0.001) compared to those only followed by PCPs. At 3-year follow-up, the absolute risk difference for mortality was 0.9% higher in ACHD patients with moderate/severe complexity lesions cared by PCPs compared to those under cardiology follow-up.

CONCLUSION

Cardiology care compared with primary care is associated with superior survival and lower rates of major complications in ACHD. It is alarming that even in a high resource setting with well-established specialist ACHD care approximately 50% of contemporary ACHD patients are still not linked to regular cardiac care. Almost all patients had at least one contact with a PCP during the study period, suggesting that opportunities to refer patients to cardiac specialists were missed at PCP level. More efforts are required to alert PCPs and patients to appropriate ACHD care.

Heart failure in adults with congenital heart disease: a narrative review

The number of adults with congenital heart disease (ACHD) has increased over the last decades due to advancements in medical care, including interventional and surgical therapies. We are therefore more frequently challenged by the long-term consequences of palliative or corrective surgery carried out during childhood. Although patients with ACHD may develop conditions related to general cardiovascular risk factors, such as coronary artery disease, the most common complications leading to morbidity and mortality are arrhythmias, heart failure and thromboembolic events. For the management of arrhythmias, current recommendations regarding ablation and device therapy must be considered, whilst also taking into account the anatomical limitations of their congenital heart defect or surgical pathways. Heart failure treatment in acute and chronic settings must also consider the particular anatomy present, including the nature of the systemic ventricle. Treatments strategies for ACHD are typically extrapolated from the respective guidelines in non-ACHD patients, despite a lack of evidence to support this strategy. Right heart failure can be especially challenging to manage in conditions where either a systemic right ventricle or shunt lesions resulting in volume and/or pressure loading of the right ventricle are present. All physicians and cardiologists in particular should be acquainted with the most common diseases in ACHD, their complications and management regime, especially with regards to heart failure as this is a common reason for acute presentation in the emergency department.

Path ahead for 'low risk' adolescents living with a Fontan circulation

OBJECTIVE

A high risk of morbidity and mortality is well documented in adults with a Fontan circulation. The difference in outcomes between those with and without significant morbidity at the time of transition to adult care has not been well characterised.

METHODS

We analysed clinical outcomes in patients enrolled in the Australian and New Zealand Fontan Registry ≥16 years of age. Low risk (LR) Fontan patients were defined as those without history of sustained arrhythmia, thromboembolic event, transplantation, Fontan conversion, protein-losing enteropathy, plastic bronchitis, New York Heart Association class III/IV and/or moderate/severe atrioventricular valve regurgitation or ventricular dysfunction. Increased risk (IR) patients had one or more risk factor.

RESULTS

Inclusion criteria were met in 822 patients; mean age 26±8 years, median follow-up from age 16 was 9 years, 203 had atriopulmonary connection (APC) and 619 had total cavopulmonary connection (TCPC). Survival at 30 years was higher in the LR versus IR; 94% versus 82% (p=0.005), 89% versus 77% (p=0.07) for APC and 96% versus 89% (p=0.05) for TCPC. LR patients experienced less Fontan failure (HR 0.34, 95% CI 0.23 to 0.49, p<0.001) and ventricular dysfunction (HR 0.46, 95% CI 0.29 to 0.71, p=0.001) compared with IR patients. For LR TCPC patients, modelled survival projections at 60 years were 49%-67%.

CONCLUSIONS

Clinical outcomes for adolescents LR at transition to adult care are markedly superior to those who have established risk factors for Fontan failure, which is an important consideration when formulating individualised long-term risk estimates and counselling patients.

European Society of Cardiology Working Group on Adult Congenital Heart Disease and Study Group for Adult Congenital Heart Care in Central and South Eastern European Countries consensus paper: current status, provision gaps and investment required

AIMS

To examine the current status of care and needs of adult congenital heart disease (ACHD) services in the Central and South Eastern European (CESEE) region.

METHODS AND RESULTS

We obtained data regarding the national ACHD status for 19 CESEE countries from their ACHD representative based on an extensive survey for 2017 and/or 2018. Thirteen countries reported at least one tertiary ACHD centre with a median year of centre establishment in 2007 (interquartile range 2002-2013). ACHD centres reported a median of 2114 patients under active follow-up with an annual cardiac catheter and surgical intervention volume of 49 and 40, respectively. The majority (90%) of catheter or surgical interventions were funded by government reimbursement schemes. However, all 19 countries had financial caps on a hospital level, leading to patient waiting lists and restrictions in the number of procedures that can be performed. The median number of ACHD specialists per country was 3. The majority of centres (75%) did not have ACHD specialist nurses. The six countries with no dedicated ACHD centres had lower Gross Domestic Product per capita compared to the remainder (P = 0.005).

CONCLUSION

The majority of countries in CESEE now have established ACHD services with adequate infrastructure and a patient workload comparable to the rest of Europe, but important gaps still exist. ACHD care is challenged or compromised by limited financial resources, insufficient staffing levels, and reimbursement caps on essential procedures compared to Western Europe. Active advocacy and increased resources are required to address the inequalities of care across the continent.

Adult congenital heart care in the COVID-19 era, and beyond: A call for action

While virus epidemics are nothing new to man, the scale, speed of global spread and immediacy of the COVID-19 pandemic have been truly unprecedented [1]. The entire world has been turned on its head in less than a few months, with major implications beyond disease burden and loss of life, threatening the economic status quo and human psychosocial balance and wellbeing not only for patients, but for all of us. The primary aim of our Call for Action Viewpoint was to support and protect our adult congenital heart disease (ACHD) patients and their needs during these challenging and uncertain times. This goal had to be met while we, as individuals, teams, institutions and nations, came together in a global effort to combat this aggressive virus, that appears to spare no organs or systems, nor any borders, geographic or other. As with any crisis, there is always opportunity: we are submitting herewith a vision for a different and better model of ACHD care, and for a better life journey and health care experience for our patients, that should be in place in the aftermath of the Covid-19 pandemic. Many of the points and principles discussed in this article, need not be confined to ACHD patients, but have a broader reach. And we must not forget nor neglect the most vulnerable in society at this time, namely the elderly, disabled and other dependent or disadvantaged groups in this "We Are One" global operation. Last but not least, this maybe the time to take better care of ourselves (and others) and reflect on life.

Machine learning algorithms estimating prognosis and guiding therapy in adult congenital heart disease: data from a single tertiary centre including 10 019 patients

AIMS

To assess the utility of machine learning algorithms on estimating prognosis and guiding therapy in a large cohort of patients with adult congenital heart disease (ACHD) or pulmonary hypertension at a single, tertiary centre.

METHODS AND RESULTS

We included 10 019 adult patients (age 36.3 ± 17.3 years) under follow-up at our institution between 2000 and 2018. Clinical and demographic data, ECG parameters, cardiopulmonary exercise testing, and selected laboratory markers where collected and included in deep learning (DL) algorithms. Specific DL-models were built based on raw data to categorize diagnostic group, disease complexity, and New York Heart Association (NYHA) class. In addition, models were developed to estimate need for discussion at multidisciplinary team (MDT) meetings and to gauge prognosis of individual patients. Overall, the DL-algorithms-based on over 44 000 medical records-categorized diagnosis, disease complexity, and NYHA class with an accuracy of 91.1%, 97.0%, and 90.6%, respectively in the test sample. Similarly, patient presentation at MDT-meetings was predicted with a test sample accuracy of 90.2%. During a median follow-up time of 8 years, 785 patients died. The automatically derived disease severity-score derived from clinical information was related to survival on Cox analysis independently of demographic, exercise, laboratory, and ECG parameters.

CONCLUSION

We present herewith the utility of machine learning algorithms trained on large datasets to estimate prognosis and potentially to guide therapy in ACHD. Due to the largely automated process involved, these DL-algorithms can easily be scaled to multi-institutional datasets to further improve accuracy and ultimately serve as online based decision-making tools.

Heart University: a new online educational forum in paediatric and adult congenital cardiac care. The future of virtual learning in a post-pandemic world?

Online learning has become an increasingly expected and popular component for education of the modern-day adult learner, including the medical provider. In light of the recent coronavirus pandemic, there has never been more urgency to establish opportunities for supplemental online learning. Heart University aims to be "the go-to online resource" for e-learning in CHD and paediatric-acquired heart disease. It is a carefully curated open access library of paedagogical material for all providers of care to children and adults with CHD or children with acquired heart disease, whether a trainee or a practising provider. In this manuscript, we review the aims, development, current offerings and standing, and future goals of Heart University.

Perioperative Echocardiography in the Adult With Congenital Heart Disease

Survival of patients with congenital heart disease has significantly improved over the last 2 decades, confronting interventionalists, surgeons, anesthesiologists, cardiologists, and intensivists with often unfamiliar complex pathophysiology in the perioperative setting. Aside from cardiac catheterization, echocardiography has become the main imaging modality in the hospitalized adult with congenital heart disease. The great variety of congenital lesions and their prior surgical management challenges practitioners to generate optimal imaging, reporting, and interpretation of these complex anatomic structures. Standardization of echocardiographic studies can not only provide significant benefits in the surveillance of these patients, but also facilitate understanding of pathophysiologic mechanism and assist clinical management in the perioperative setting. Knowledge in obtaining and interpreting uniform imaging protocols is essential for the perioperative clinician. In this publication, the authors review current international consensus recommendations on echocardiographic imaging of adults with congenital heart disease and describe the fundamental components by specific lesion. The authors will emphasize key aspects pertinent to the clinical management when imaging these patients in the perioperative setting. The goal of this review is to familiarize the perioperative physician on how to structure and standardize echocardiographic image acquisition of congenital heart disease anatomy for optimal clinical management.

Outpatient volumes and medical staffing resources as predictors for continuity of follow-up care during transfer of adolescents with congenital heart disease

BACKGROUND

Providing continuous follow-up care to patients with congenital heart disease (CHD) remains a challenge in many settings. Previous studies highlight that patients with CHD experience discontinuation of follow-up care, but mainly describe a single-centre perspective, neglecting inter-institutional variations. Hospital-related factors above and beyond patient-related factors are believed to affect continuity of care. The present multicentre study therefore investigated (i) proportion of "no follow-up care"; (ii) transfer destinations after leaving paediatric cardiology; (iii) variation in proportions of no follow-up between centres; (iv) the association between no follow-up and outpatient volumes, and (v) its relationship with staffing resources at outpatient clinics.

METHODS

An observational, multicentre study was conducted in seven university hospitals. In total, 654 adolescents with CHD, born between 1991 and 1993, with paediatric outpatient visit at age 14-18 years were included. Transfer status was determined 5 years after the intended transfer to adult care (23y), based on medical files, self-reports and registries.

RESULTS

Overall, 89.7% of patients were receiving adult follow-up care after transfer; 6.6% had no follow-up; and 3.7% were untraceable. Among patients in follow-up care, only one remained in paediatric care and the majority received specialist adult CHD care. Significant variability in proportions of no follow-up were identified across centres. Higher outpatient volumes at paediatric outpatient clinics were associated with better continued follow-up care after transfer (OR = 1.061; 95% CI = 1.001 - 1.124). Medical staffing resources were not found predictive.

CONCLUSION

Our findings support the theory of hospital-related factors influencing continuity of care, above and beyond patient-related characteristics.

Opinions of general and adult congenital heart disease cardiologists on care for adults with congenital heart disease in Belgium: a qualitative study

BACKGROUND

The growing adult congenital heart disease (CHD) population requires efficient healthcare organisation. It has been suggested that clinically appropriate care be provided for individual patients on the least complex level possible, in order to alleviate saturation of special care programmes.

METHODS

Semi-structured interviews with 10 general and 10 adult CHD cardiologists were conducted to elucidate opinions on healthcare organisation in Belgium. A particular focus was placed on the potential role of general cardiologists. The software program NVivo 12 facilitated thematic analysis.

RESULTS

A discrepancy existed between how general cardiologists thought about congenital care and what adult CHD cardiologists considered the minimum knowledge required to adequately treat patients. Qualitative data were categorised under the following themes: knowledge dissemination, certification, (de)centralisation of care, the role of adult CHD cardiologists, the role of dedicated nurse specialists, and patient referral. It appeared to be pivotal to organise care in such a way that providing basic care locally does not impede the generation of sufficient patient volume, and to continue improving communications between different care levels when there is no referral back. Moreover, practical knowledge is best disseminated locally. Cardiologists' opinions on certification and on the role of dedicated nurse specialists were mixed.

CONCLUSION

On the basis of the results, we propose five recommendations for improving the provision of care to adults with CHD. A multidimensional approach to defining the role of different healthcare professionals, to improving communication channels, and to effectively sensitising healthcare professionals is needed to improve the organisation of care.

Real-world healthcare utilization in adult congenital heart disease: a systematic review of trends and ratios

BACKGROUND

As a result of medical advances, the adult congenital heart disease population is rapidly expanding. Nonetheless, most patients remain prone to increased morbidity and mortality. Therefore, long-term medical resource use is required. This systematic review aims to present the trends over the past decades of medical resource utilization in adult congenital heart disease as well as its current status, with a focus on hospitalizations, emergency department visits, outpatient cardiology visits, and visits to other healthcare professionals.

METHODS

MEDLINE (Pubmed), Embase, and Web of Science were searched for retrospective database research publications. The ISPOR checklist for retrospective database research was used for quality appraisal. Trends over time are explored.

RESULTS

Twenty-one articles met the inclusion criteria. All but one of the studies was conducted in Western Europe and North America. The absolute number of hospitalizations has been increasing over the last several decades. This increase is highest in patients with mild lesions, although these numbers are largely driven by hospitalizations of patients with an atrial septal defect or a patent foramen ovale. Meanwhile, outpatient cardiology visits are increasing at an even higher pace, and occur most often in geriatric patients and patients with severe lesions. Conversely, the number of hospitalizations per 100 patients is decreasing over time. Literature is scarce on other types of healthcare use.

CONCLUSION

A strong rise in healthcare utilization is noticed, despite the mitigating effect of improved efficiency levels. As the population continues to grow, innovative medical management strategies will be required to accommodate its increasing healthcare utilization.

Traversing the liminal: what can Fontan adults' transition experiences and perspectives teach us about optimizing healthcare?

BACKGROUND

Successfully transitioning to adult care is important for congenital heart disease (CHD) patients, particularly those at the worst end of the spectrum with a Fontan circulation, as their ongoing health engagement affects their health outcomes. Yet, there is a lack of literature exploring patient perspectives about their transition experiences, and what helps or hinders successful transition to adult care.

METHODS

Young adults with a Fontan circulation (n = 18) from the Australian and New Zealand Fontan Registry participated in in-depth phone interviews. Thematic analyses were used to analyze the qualitative interview data.

RESULTS

We identified six key themes which stood out from patient experiences, including differences between pediatric and adult congenital cardiac care, the need for preparation through formal transition programs, and the important role of support systems.

CONCLUSION

To become active managers of their healthcare and remain engaged with the healthcare system, young people would benefit from coordinated efforts between pediatric and adult care to formally prepare them for transition to adult care. This should include involvement from their support network and ongoing education about their health condition. The study highlights the importance of studying patient perspectives through qualitative research to better inform health service provision in the CHD space.
