Advocacy at the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery.

The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery (WCPCCS) will be held in Washington DC, USA, from Saturday, 26 August, 2023 to Friday, 1 September, 2023, inclusive. The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery will be the largest and most comprehensive scientific meeting dedicated to paediatric and congenital cardiac care ever held. At the time of the writing of this manuscript, The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery has 5,037 registered attendees (and rising) from 117 countries, a truly diverse and international faculty of over 925 individuals from 89 countries, over 2,000 individual abstracts and poster presenters from 101 countries, and a Best Abstract Competition featuring 153 oral abstracts from 34 countries. For information about the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery, please visit the following website: [www.WCPCCS2023.org]. The purpose of this manuscript is to review the activities related to global health and advocacy that will occur at the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery.Acknowledging the need for urgent change, we wanted to take the opportunity to bring a common voice to the global community and issue the Washington DC WCPCCS Call to Action on Addressing the Global Burden of Pediatric and Congenital Heart Diseases. A copy of this Washington DC WCPCCS Call to Action is provided in the Appendix of this manuscript. This Washington DC WCPCCS Call to Action is an initiative aimed at increasing awareness of the global burden, promoting the development of sustainable care systems, and improving access to high quality and equitable healthcare for children with heart disease as well as adults with congenital heart disease worldwide.

Recommendations for developing effective and safe paediatric and congenital heart disease services in low-income and middle-income countries: a public health framework.

The global burden of paediatric and congenital heart disease (PCHD) is substantial. We propose a novel public health framework with recommendations for developing effective and safe PCHD services in low-income and middle-income countries (LMICs). This framework was created by the Global Initiative for Children's Surgery Cardiac Surgery working group in collaboration with a group of international rexperts in providing paediatric and congenital cardiac care to patients with CHD and rheumatic heart disease (RHD) in LMICs. Effective and safe PCHD care is inaccessible to many, and there is no consensus on the best approaches to provide meaningful access in resource-limited settings, where it is often needed the most. Considering the high inequity in access to care for CHD and RHD, we aimed to create an actionable framework for health practitioners, policy makers and patients that supports treatment and prevention. It was formulated based on rigorous evaluation of available guidelines and standards of care and builds on a consensus process about the competencies needed at each step of the care continuum. We recommend a tier-based framework for PCHD care integrated within existing health systems. Each level of care is expected to meet minimum benchmarks and ensure high-quality and family centred care. We propose that cardiac surgery capabilities should only be developed at the more advanced levels on hospitals that have an established foundation of cardiology and cardiac surgery services, including screening, diagnostics, inpatient and outpatient care, postoperative care and cardiac catheterisation. This approach requires a quality control system and close collaboration between the different levels of care to facilitate the journey and care of every child with heart disease. This effort was designed to guide readers and leaders in taking action, strengthening capacity, evaluating impact, advancing policy and engaging in partnerships to guide facilities providing PCHD care in LMICs.

The Role of Congenital Heart Disease Patient Organizations in Advocacy, Resources, and Support Across the Lifespan.

Congenital heart disease patient organizations, comprising experts with lived experience, and their families and supporters, have become an essential voice for patient advocacy, resources, and support. Thanks largely to the Internet, these organizations are growing in number worldwide. Their common voice can be used to influence research, be the catalyst for advocacy efforts for new programmes and supports, and connect patients and providers in endeavours beyond the clinical setting. The result has become more active engagement with how policy decisions, research directions, and laws are decided that will shape patients' lives. From advocating for much-needed mental health support, policies to combat discrimination and the lack of access to support services, and partnerships with clinicians and others to develop educational resources and tools, congenital heart disease patient organizations are having a considerable impact on patient lives and ultimately patient outcomes.

Les organisations formées de patients atteints d'une cardiopathie congénitale (CC), qui sont de par leur vécu des experts en la matière, de membres de leur famille et de personnes qui les soutiennent, jouent un rôle crucial pour défendre les intérêts des patients et leur offrir des ressources et du soutien. Dans une large mesure grâce à l'Internet, le nombre de ces organisations est en croissance partout au monde. La mise en commun de leur voix peut influencer la recherche, servir de catalyseur aux initiatives en faveur de nouveaux programmes et de nouvelles formes de soutien, et contribuer à établir des liens entre les patients et les cliniciens au-delà du contexte clinique. La prise de décisions concernant les politiques, les orientations de recherche et les lois peut par conséquent bénéficier d'une participation plus active des patients, qui sont les premiers concernés. Ces organisations exercent une grande influence sur la vie des patients et, en fin de compte, sur leurs résultats cliniques, notamment grâce à tous les efforts qu'ils consacrent à la revendication d'un soutien en santé mentale, qui fait grandement défaut, de politiques de lutte contre la discrimination et le manque d'accès aux services de soutien ainsi que de partenariats avec des cliniciens et d'autres alliés dans le but de concevoir des ressources et des outils éducatifs.

Global Access to Comprehensive Care for Paediatric and Congenital Heart Disease.

Paediatric and congenital heart disease (PCHD) is common but remains forgotten on the global health agenda. Congenital heart disease is the most frequent major congenital anomaly, affecting approximately 1 in every 100 live births. In high-income countries, most children now live into adulthood, whereas in low- and middle-income countries, over 90% of patients do not get the care they need. Rheumatic heart disease is the most common acquired cardiovascular disease in children and adolescents. While almost completely eradicated in high-income countries, over 30-40 million people live with rheumatic heart disease in low- and middle-income countries. Challenges exist in the care for PCHD and, increasingly, adult congenital heart disease (ACHD) worldwide. In this review, we summarize the current status of PCHD and ACHD care through the health systems lens of workforce, infrastructure, financing, service delivery, information management and technology, and governance. We further highlight gaps in knowledge and opportunities moving forward to improve access to care for all those living with PCHD or ACHD worldwide.

Les cardiopathies pédiatriques et congénitales (CPC) sont fréquentes, mais demeurent dans l'angle mort des politiques de santé mondiale. La cardiopathie est l'anomalie congénitale majeure la plus fréquente; elle touche environ 1 naissance vivante sur 100. Dans les pays à revenus élevés, la plupart de ces enfants atteignent désormais l'âge adulte, tandis que dans ceux à revenus faibles ou moyens, plus de 90 % des patients n'obtiennent pas les soins dont ils ont besoin. La cardiopathie rhumatismale est la maladie cardiovasculaire acquise la plus fréquente chez les enfants et les adolescents. Alors qu'elle est pratiquement éradiquée dans les pays à revenus élevés, plus de 30 à 40 millions de personnes en sont atteintes dans les pays à revenus faibles et moyens. À l'échelle mondiale, il existe de nombreux obstacles aux soins des CPC et, de plus en plus, des cardiopathies congénitales chez l'adulte (CCA). Notre article de synthèse présente un résumé de l'état actuel des soins des CPC et des CCA en abordant plusieurs aspects des systèmes de santé : ressources humaines, infrastructures, financement, services offerts, gestion des renseignements, technologies de l'information et gouvernance. Nous mettons également en lumière des lacunes dans les connaissances et des avenues d'amélioration de l'accès aux soins pour les personnes atteintes de CPC et de CCA partout dans le monde.

Transition to adulthood and transfer to adult care of adolescents with congenital heart disease: a global consensus statement of the ESC Association of Cardiovascular Nursing and Allied Professions (ACNAP), the ESC Working Group on Adult Congenital Heart Disease (WG ACHD), the Association for European Paediatric and Congenital Cardiology (AEPC), the Pan-African Society of Cardiology (PASCAR), the Asia-Pacific Pediatric Cardiac Society (APPCS), the Inter-American Society of Cardiology (IASC), the Cardiac Society of Australia and New Zealand (CSANZ), the International Society for Adult Congenital Heart Disease (ISACHD), the World Heart Federation (WHF), the European Congenital Heart Disease Organisation (ECHDO), and the Global Alliance for Rheumatic and Congenital Hearts (Global ARCH).

The vast majority of children with congenital heart disease (CHD) in high-income countries survive into adulthood. Further, paediatric cardiac services have expanded in middle-income countries. Both evolutions have resulted in an increasing number of CHD survivors. Expert care across the life span is necessitated. In adolescence, patients transition from being a dependent child to an independent adult. They are also advised to transfer from paediatrics to adult care. There is no universal consensus regarding how transitional care should be provided and how the transfer should be organized. This is even more challenging in countries with low resources. This consensus document describes issues and practices of transition and transfer of adolescents with CHD, accounting for different possibilities in high-, middle-, and low-income countries. Transitional care ought to be provided to all adolescents with CHD, taking into consideration the available resources. When reaching adulthood, patients ought to be transferred to adult care facilities/providers capable of managing their needs, and systems have to be in place to make sure that continuity of high-quality care is ensured after leaving paediatric cardiology.

Development of an international standard set of clinical and patient-reported outcomes for children and adults with congenital heart disease: a report from the International Consortium for Health Outcomes Measurement Congenital Heart Disease Working Group.

AIMS: Congenital heart disease (CHD) is the most common congenital malformation. Despite the worldwide burden to patient wellbeing and health system resource utilization, tracking of long-term outcomes is lacking, limiting the delivery and measurement of high-value care. To begin transitioning to value-based healthcare in CHD, the International Consortium for Health Outcomes Measurement aligned an international collaborative of CHD experts, patient representatives, and other stakeholders to construct a standard set of outcomes and risk-adjustment variables that are meaningful to patients. METHODS AND RESULTS: The primary aim was to identify a minimum standard set of outcomes to be used by health systems worldwide. The methodological process included four key steps: (i) develop a working group representative of all CHD stakeholders; (ii) conduct extensive literature reviews to identify scope, outcomes of interest, tools used to measure outcomes, and case-mix adjustment variables; (iii) create the outcome set using a series of multi-round Delphi processes; and (iv) disseminate set worldwide. The Working Group established a 15-item outcome set, incorporating physical, mental, social, and overall health outcomes accompanied by tools for measurement and case-mix adjustment variables. Patients with any CHD diagnoses of all ages are included. Following an open review process, over 80% of patients and providers surveyed agreed with the set in its final form. CONCLUSION: This is the first international development of a stakeholder-informed standard set of outcomes for CHD. It can serve as a first step for a lifespan outcomes measurement approach to guide benchmarking and improvement among health systems.

Adult congenital cardiac life-long needs evaluation in a low-middle income country, Pakistan.

OBJECTIVE: Adult congenital heart diseases (ACHD) have distinct health care needs that require life-long care. Limited data is available from low-middle income countries (LMIC). This descriptive study conducted in Pakistan, aimed to assess patients and health care professionals understanding of the needs for ACHD care and the perceived barriers to care. METHODS: A telephone survey was conducted of ACHD patients. An e mail survey was sent to the paediatric and adult cardiologists of five institutions (3 public and 2 private) that provide ACHD services in Pakistan. Descriptive statistics (frequencies, mean ± SD, median) were used for data analysis. RESULTS: A total of 128 ACHD patients were surveyed, 65 (51%) were females with a mean age of 29.4±10.4 years. Atrial septal defect repair was the most common surgical procedure. Mean age at surgery was 25.6±10.49 years, and a surgical follow-up period of 3.8±2.3 years. Majority (n=3, 60%) of the health care professionals (HCPs) responded that 75-100% of the ACHD surgical patients would need lifelong care, yet 10-25% return to their cardiology clinics. Most of the surveyed ACHD patients (89%, n=114) demonstrated a lack of understanding of life-long care after surgery due to not being communicated by their HCPs. Cost and travelling issues were the barriers highlighted by HCPs. Both ACHD patients (96%, n=122) and HCP (100%, n=5) underscored their interest in life long care. CONCLUSIONS: Majority of ACHD patients in Pakistan did not know that life-long follow-up is needed. Education regarding lifelong care for ACHD patients was identified as a means to alleviate the knowledge gap.

Knowledge of Life-Long Cardiac Care by Adolescents and Young Adults with Congenital Heart Disease.

National management guidelines recommend that patients with moderate and complex congenital heart disease (CHD) receive life-long cardiac care (LLCC), guided in adulthood by an adult congenital heart disease (ACHD) specialist. However, the percentage of adult CHD patients who receive such care is quite low. Inadequate knowledge regarding LLCC may contribute to care interruption. We, therefore, sought to determine the knowledge of adolescents and young adults regarding LLCC. In this multi-center study, we administered a survey to patients 13-20 years of age with surgically repaired congenital heart disease. We assessed the understanding of both their need for LLCC and awareness of the type of recommended care providers. A total of 290/302 (96%) patients approached in the outpatient clinic setting (10 centers) agreed to study participation; mean age was 16.3 ± 2.3 years; patients were 62% male. While the need for LLCC was recognized by 78% of subjects, only 37% understood that an ACHD specialist in adulthood should guide this care. Only 37% of respondents stated that their current cardiology team had spoken to them about LLCC, but 90% wished to learn more. A substantial number of adolescents and young adults with moderate and complex CHD lack adequate knowledge about LLCC, but most have a desire to learn more about the type of care they will require in adulthood. Transition education/assessment ensuring successful transfer to adult-oriented care for this population should emphasize the importance of LLCC.

Electronic medical record integration with a database for adult congenital heart disease: Early experience and progress in automating multicenter data collection.

BACKGROUND: The adoption of electronic health records (EHR) has created an opportunity for multicenter data collection, yet the feasibility and reliability of this methodology is unknown. The aim of this study was to integrate EHR data into a homogeneous central repository specifically addressing the field of adult congenital heart disease (ACHD). METHODS: Target data variables were proposed and prioritized by consensus of investigators at five target ACHD programs. Database analysts determined which variables were available within their institutions' EHR and stratified their accessibility, and results were compared between centers. Data for patients seen in a single calendar year were extracted to a uniform database and subsequently consolidated. RESULTS: From 415 proposed target variables, only 28 were available in discrete formats at all centers. For variables of highest priority, 16/28 (57%) were available at all four sites, but only 11% for those of high priority. Integration was neither simple nor straightforward. Coding schemes in use for congenital heart diagnoses varied and would require additional user input for accurate mapping. There was considerable variability in procedure reporting formats and medication schemes, often with center-specific modifications. Despite the challenges, the final acquisition included limited data on 2161 patients, and allowed for population analysis of race/ethnicity, defect complexity, and body morphometrics. CONCLUSION: Large-scale multicenter automated data acquisition from EHRs is feasible yet challenging. Obstacles stem from variability in data formats, coding schemes, and adoption of non-standard lists within each EHR. The success of large-scale multicenter ACHD research will require institution-specific data integration efforts.

Clinicians' perspectives on patient satisfaction in adult congenital heart disease clinics--a dimension of health care quality whose time has come.

OBJECTIVES: Patient-centered care and patient satisfaction represent key dimensions of health care quality. This is relevant for the growing number of patients with life-long conditions. In the present study, our goal was to examine clinicians' attitudes and behavior with respect to patient satisfaction in adult congenital heart disease outpatient clinics. METHODS: A 34-question survey was developed to assess adult congenital heart disease clinicians' awareness, attitudes, and behavior relative to patient satisfaction and administered in-person or online to clinicians from the largely U.S.-based Adult Congenital Heart Association's database of adult congenital heart disease health care providers. RESULTS: Overall, 267 questionnaires were filled out: 108 were collected in person (79% response rate) and 159 online (17.5% response rate). Responses were received from physicians (161); nurses (73); physician assistants (20); and others (13). Although 85% of clinicians believed it was important to inquire about patient satisfaction, only 28% reported routinely inquiring about this dimension of care. Only 34% claimed they had adequate training to cope with varying levels of patient satisfaction, 44% stated that their department utilized patient satisfaction surveys, and 37% received feedback from the hospital management in the preceding 12 months. In multivariate analyses, clinicians that received feedback from the hospital management and had adequate training were more likely to inquire about patient satisfaction. CONCLUSION: Although patient satisfaction is perceived as an important dimension of quality care by adult congenital heart disease clinicians, most of them reported insufficient institutional support to achieve this. Our findings suggest that clinicians would benefit from health care organizations engaging them in the delivery of this dimension of health care quality.

Clinical research priorities in adult congenital heart disease.

BACKGROUND: Adult congenital heart disease (ACHD) clinicians are hampered by the paucity of data to inform clinical decision-making. The objective of this study was to identify priorities for clinical research in ACHD. METHODS: A list of 45 research questions was developed by the Alliance for Adult Research in Congenital Cardiology (AARCC), compiled into a survey, and administered to ACHD providers. Patient input was sought via the Adult Congenital Heart Association at community meetings and online forums. The 25 top questions were sent to ACHD providers worldwide via an online survey. Each question was ranked based on perceived priority and weighted based on time spent in ACHD care. The top 10 topics identified are presented and discussed. RESULTS: The final online survey yielded 139 responses. Top priority questions related to tetralogy of Fallot (timing of pulmonary valve replacement and criteria for primary prevention ICDs), patients with systemic right ventricles (determining the optimal echocardiographic techniques for measuring right ventricular function, and indications for tricuspid valve replacement and primary prevention ICDs), and single ventricle/Fontan patients (role of pulmonary vasodilators, optimal anticoagulation, medical therapy for preservation of ventricular function, treatment for protein losing enteropathy). In addition, establishing criteria to refer ACHD patients for cardiac transplantation was deemed a priority. CONCLUSIONS: The ACHD field is in need of prospective research to address fundamental clinical questions. It is hoped that this methodical consultation process will inform researchers and funding organizations about clinical research topics deemed to be of high priority.

Improving heart disease knowledge and research participation in adults with congenital heart disease (the Health, Education and Access Research Trial: HEART-ACHD).

OBJECTIVE: The objective of this prospective multi-center study was to evaluate heart disease knowledge within the adult congenital heart disease (ACHD) population, pilot an educational intervention and assess interest in research participation among new patients at ACHD clinics. BACKGROUND: Many adults with congenital heart disease lack knowledge about their heart condition that may contribute to undesirable outcomes. METHODS: Patients ≥18 years of age were recruited upon their first presentation to an ACHD clinic and underwent an educational intervention consisting of creation of a personal health information 'passport' and an introduction to web-based resources. Subjects were asked to complete initial and follow-up surveys documenting their perceived knowledge. RESULTS: Nine hundred twenty-two subjects were recruited from 12 ACHD centers, and 520 (57%) completed follow-up surveys. Patients who completed the follow-up survey were more likely to be women, have more education, and have mild heart disease. At follow-up, the ability of the subjects to name their heart condition improved (78% to 83%, p=0.002). Improvements were seen in mean Likert items regarding perceived knowledge of appropriate exercise (p<0.0001), symptoms of heart rhythm problems or endocarditis (p<0.0001), reasons for cardiac tests (p<0.007), and birth control options and pregnancy safety (p<0.0001). On follow-up, subjects reported a better understanding of medical research (p<0.01), and higher interest in research participation (p<0.003). CONCLUSION: This joint clinician-patient pilot program will help inform future efforts toward patient education and participation in research with a focus on standardization of protocols for life-long longitudinal follow-up and continued multi-center collaboration in the ACHD population.

Prevalence and predictors of gaps in care among adult congenital heart disease patients: HEART-ACHD (The Health, Education, and Access Research Trial).

OBJECTIVES: The goal of this project was to quantify the prevalence of gaps in cardiology care, identify predictors of gaps, and assess barriers to care among adult congenital heart disease (adult CHD) patients. BACKGROUND: Adult CHD patients risk interruptions in care that are associated with undesired outcomes. METHODS: Patients (18 years of age and older) with their first presentation to an adult CHD clinic completed a survey regarding gaps in, and barriers to, care. RESULTS: Among 12 adult CHD centers, 922 subjects (54% female) were recruited. A >3-year gap in cardiology care was identified in 42%, with 8% having gaps longer than a decade. Mean age at the first gap was 19.9 years. The majority of respondents had more than high school education and knew their heart condition. The most common reasons for gaps included feeling well, being unaware that follow-up was required, and complete absence from medical care. Disease complexity was predictive of a gap in care with 59% of mild, 42% of moderate, and 26% of severe disease subjects reporting gaps (p < 0.0001). Clinic location significantly predicted gaps (p < 0.0001), whereas sex, race, and education level did not. Common reasons for returning to care were new symptoms, referral from provider, and desire to prevent problems. CONCLUSIONS: Adult CHD patients have gaps in cardiology care; the first lapse commonly occurred at age ∼19 years, a time when transition to adult services is contemplated. Gaps were more common among subjects with mild and moderate diagnoses and at particular locations. These results provide a framework for developing strategies to decrease gaps and address barriers to care in the adult CHD population.

Parental knowledge regarding lifelong congenital cardiac care.

OBJECTIVE: To assess parental knowledge regarding lifelong congenital cardiac care (LLCCC). BACKGROUND: National guidelines recommend that nearly 50% of adult survivors with congenital heart disease (CHD) receive LLCCC; the number of adults who receive such care seems far less. Inadequate parental knowledge of LLCCC might contribute to care interruption. METHODS: In this multicenter study, we administered a questionnaire to parents of children with moderate and complex CHD to assess knowledge of LLCCC. RESULTS: A total of 500 parents participated; the median age of their children was 10 years (range: 2-18 years). Most parents (81%) understood that their child would need LLCCC, but only 44% recognized that their child's cardiology care should be guided by an adult congenital heart specialist in adulthood. More than half (59%) of the parents stated that their current cardiology team had never spoken to them about LLCCC, but 96% wished to learn more. Variables associated with parental LLCCC knowledge included previous discussions regarding LLCCC, underlying cardiac surgical diagnosis, and level of parental education. CONCLUSIONS: A substantial number of parents of children with moderate and complex CHD lack knowledge about LLCCC, but almost all of them have a desire to learn more about the care their child will need as an adult.

The whole adult congenital heart disease patient.

Adults with congenital heart disease (CHD) have unique medical and psychosocial needs. They require lifelong cardiac surveillance from medical providers with training and expertise in the care of adults with CHD. Patients with CHD must recognize the importance of ongoing surveillance and must not be lost to care in childhood, adolescence, or adulthood. This can be accomplished with the implementation of a comprehensive transition program with the collaboration of patients, parents, and both pediatric and adult health care providers. Finally, consideration of the "whole" patient demands recognition of the unique medical and psychosocial challenges of adults with CHD.

Attitude toward and current practice of transfer and transition of adolescents with congenital heart disease in the United States of America and Europe.

The objective of this study was to explore the current practice and attitudes of pediatric cardiologists in the United States and Europe on the transfer and transition of children with congenital heart disease (CHD). A survey among pediatric cardiology programs in the United States and Europe was undertaken. Sixty-nine centers completed and returned the 61-item questionnaire that was specifically devised for this survey. Of 69 participating centers, 74% reported that they transfer their patients to adult-focused care. When a center transfers its patients, 80% transfer them to a formalized Adult Congenital Heart Disease Program. The median age of transfer is 18 years. Comorbidities, pregnancy, and patient/family request to leave pediatric cardiology were identified as initiators for transfer. Complexity of the heart defect was relatively less important when deciding whether to transfer patients. Only one-third of the centers that transfer their patients provide a structured preparation for patients and family. Development of a formal transition program is planned at 59% of the centers that transfer patients. In conclusion, timely transfer and a structured transition process of children with CHD are not implemented in all pediatric cardiology programs. Health-care providers working in pediatric cardiology should make their transfer policies explicit and transition programs ought to be developed.

Adult congenital heart disease: the patient's perspective.

This article presents the adult congenital heart disease (ACHD) patient "voice" by high-lighting issues and challenges commonly identified in peer support forums but rarely addressed in the existing literature. Representative patient quotations are provided, and relevant research on patient education and psychosocial function is referenced. Issues discussed include the provision of overly pessimistic and overly optimistic prognoses, common patient misperceptions and knowledge gaps, frustrations and dangerous encounters in the medical system, and living with invisible disabilities. Patient self-perception of congenital heart disease, the gifts of congenital heart disease, and the role of patient associations are also discussed. For each issue identified, implications for the ACHD health professional are outlined and recommendations for best practices are made.

Transition and transfer from pediatric to adult care of the young adult with complex congenital heart disease.

This article focuses first on the process of transition and transfer of care of young adults with complex congenital heart disease. It defines the transition process and briefly discusses its history. It reviews the important aspects of transition, outlines the key elements of a successful transition program, and provides a curriculum appropriate for the young adult with congenital heart disease. Finally, it identifies the barriers to transfer of care, discusses the importance of a policy on timing, outlines the components of adult provider services that may be needed, and reviews the steps to an orderly transfer process.

Report of the National Heart, Lung, and Blood Institute Working Group on research in adult congenital heart disease.

The Working Group on research in adult congenital heart disease (ACHD) was convened in September 2004 under the sponsorship of National Heart, Lung, and Blood Institute (NHLBI) and the Office of Rare Diseases, National Institutes of Health, Department of Health and Human Services, to make recommendations on research needs. The purpose of the Working Group was to advise the NHLBI on the current state of the science in ACHD and barriers to optimal clinical care, and to make specific recommendations for overcoming those barriers. The members of the Working Group were chosen to provide expert input on a broad range of research issues from both scientific and lay perspectives. The Working Group reviewed data on the epidemiology of ACHD, long-term outcomes of complex cardiovascular malformations, issues in assessing morphology and function with current imaging techniques, surgical and catheter-based interventions, management of related conditions including pregnancy and arrhythmias, quality of life, and informatics. After research and training barriers were discussed, the Working Group recommended outreach and educational programs for adults with congenital heart disease, a network of specialized adult congenital heart disease regional centers, technology development to support advances in imaging and modeling of abnormal structure and function, and a consensus on appropriate training for physicians to provide care for adults with congenital heart disease.
