The 1st World Congress of Paediatric Cardiology was held in London, United Kingdom, in 1980, organised by Dr Jane Somerville and Prof. Fergus Macartney. The idea was that of Jane Somerville, who worked with enormous energy and enthusiasm to bring together paediatric cardiologists and surgeons from around the world. The 2nd World Congress of Paediatric Cardiology took place in New York in 1985, organised by Bill Rashkind, Mary Ellen Engle, and Eugene Doyle. The 3rd World Congress of Paediatric Cardiology was held in Bangkok, Thailand, in 1989, organised by Chompol Vongraprateep. Although cardiac surgeons were heavily involved in these early meetings, a separate World Congress of Paediatric Cardiac Surgery was held in Bergamo, Italy, in 1988, organised by Lucio Parenzan. Thereafter, it was recognised that surgeons and cardiologists working on the same problems and driven by a desire to help children would really rather meet together. A momentous decision was taken to initiate a Joint World Congress of Paediatric Cardiology and Cardiac Surgery. A steering committee was established with membership comprising the main organisers of the four separate previous Congresses and additional members were recruited in an effort to achieve numerical equality of cardiologists and surgeons and a broad geographical representation. The historic 1st “World Congress of Paediatric Cardiology and Cardiac Surgery” took place in Paris in June, 1993, organised by Jean Kachaner. The next was to be held in Japan, but the catastrophic Kobe earthquake in 1995 forced relocation to Hawaii in 1997. Then followed Toronto, Canada, 2001, organised by Bill Williams and Lee Benson; Buenos Aires, Argentina, 2005, organised by Horatio Capelli and Guillermo Kreutzer; Cairns, Australia, 2009, organised by Jim Wilkinson; Cape Town, South Africa, 2013, organised by Christopher Hugo-Hamman; and Barcelona, Spain, 2017, organised by Sertac Cicek. With stops in Europe (1993), Asia-Pacific (1997), North America (2001), South America (2005), Australia (2009), Africa (2013), and Europe again (2017), in 2021, The World Congress of Paediatric Cardiology and Cardiac Surgery will be held for the first time in the continental United States.1 The 8th World Congress of Paediatric Cardiology and Cardiac Surgery will be held in Washington DC, United States of America, 19–24 September, 2021, and will be organised by Jeffrey P. Jacobs and Gil Wernovsky. Mitchell I. Cohen served as the Scientific Program Co-Chair for the 2017 World Congress of Paediatric Cardiology and Cardiac Surgery, and he will again serve as the Scientific Program Co-Chair for the 2021 World Congress of Paediatric Cardiology and Cardiac Surgery along with Kathyrn Dodds RN, MSN, CRNP.

An internationally approved and globally used classification scheme for the diagnosis of CHD has long been sought. The International Paediatric and Congenital Cardiac Code (IPCCC), which was produced and has been maintained by the International Society for Nomenclature of Paediatric and Congenital Heart Disease (the International Nomenclature Society), is used widely, but has spawned many “short list” versions that differ in content depending on the user. Thus, efforts to have a uniform identification of patients with CHD using a single up-to-date and coordinated nomenclature system continue to be thwarted, even if a common nomenclature has been used as a basis for composing various “short lists”. In an attempt to solve this problem, the International Nomenclature Society has linked its efforts with those of the World Health Organization to obtain a globally accepted nomenclature tree for CHD within the 11th iteration of the International Classification of Diseases (ICD-11). The International Nomenclature Society has submitted a hierarchical nomenclature tree for CHD to the World Health Organization that is expected to serve increasingly as the “short list” for all communities interested in coding for congenital cardiology. This article reviews the history of the International Classification of Diseases and of the IPCCC, and outlines the process used in developing the ICD-11 congenital cardiac disease diagnostic list and the definitions for each term on the list. An overview of the content of the congenital heart anomaly section of the Foundation Component of ICD-11, published herein in its entirety, is also included. Future plans for the International Nomenclature Society include linking again with the World Health Organization to tackle procedural nomenclature as it relates to cardiac malformations. By doing so, the Society will continue its role in standardising nomenclature for CHD across the globe, thereby promoting research and better outcomes for fetuses, children, and adults with congenital heart anomalies.

In the opening plenary address of the 2017 7th World Congress of Pediatric Cardiology and Cardiac Surgery the author, who represented the World Society for Pediatric and Congenital Heart Surgery at the Congress and is currently the Society’s president, described the history of the formation of the World Society. He listed accomplishments of the World Society including publication of the only journal devoted to congenital cardiac surgery, development of a global database, and convening several international conferences dating back to the inaugural conference in Washington, DC in 2007. The general theme of the presentation is the importance of teamwork in managing patients and families with CHD. Challenges facing congenital heart teams are discussed including the fragility of cardiac programmes, that can be heavily influenced by the administrative structure of a paediatric hospital; the difficulty of recruiting skilled surgeons into the field as training in general cardiothoracic surgery contracts and general surgery becomes predominantly laparoscopic with few open procedures; and increasing barriers to the international movement of surgeons including the opportunities for United States of America-based surgeons to acquire international experience at leading global centres. Finally, the author focusses on the danger that the team approach poses to maintaining empathy and emotional support for the family with CHD undergoing a stressful hospitalisation. He discusses strategies to optimise holistic support of the child and family.

The importance of teamwork is being increasingly recognised in healthcare. Nonetheless, it is equally recognised that teamwork is difficult. In this article, I explore whether we can learn lessons from musicians, orchestras, and conductors as we build our teams. The evolution of the role of the conductor provides useful lessons on leadership and the evolving role of the members of the orchestra on how team members can contribute to a shared outcome. The uncertainty of jazz provides useful lessons for innovation in an increasingly turbulent healthcare environment.

Over the past decades, survival of patients with CHD improved significantly, making it a life-cycle disease. Hence, there is a need for a workforce that can take up the care for afflicted individuals in the different phases of the life spectrum. Each life phase is associated with specific challenges. Topics that should receive more attention in clinical care or in CHD research are parenting styles of parents of children, transfer and transition of adolescents, cumulative burden of injury in the brain in adults, and geriatric care for older persons with CHD. Nurses, along with other healthcare professionals, will play a pivotal role in building up expertise in these areas and taking up these challenges.

Marfan syndrome, bicuspid aortic valve, and/or coarctation of the aorta are associated with medial abnormalities of the ascending aortic or para-coarctation aorta. Medial abnormalities in the ascending aorta are prevalent in other type of patients with a variety of CHDs such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic left heart syndrome, and tetralogy of Fallot, encompassing a wide age range and may predispose to dilatation, aneurysm, and rapture necessitating aortic valve and root surgery. These CHDs exhibit ongoing dilatation of the aortic root and reduced aortic elasticity and increased aortic stiffness that may relate to intrinsic properties of the aortic root. These aortic dilatation and increased stiffness can induce aortic aneurysm, rapture of the aorta, and aortic regurgitation, but also provoke left ventricular hypertrophy, reduced coronary artery flow, and left ventricular failure. Therefore, a new clinical entity can be used to call this association of aortic pathophysiological abnormality, aortic dilation, and aorto-left ventricular interaction – “aortopathy”.

Cardiac anesthesia and critical care provide an important continuum of care for patients with congenital heart disease. Clinicians in both areas work in complex environments in which the interactions between humans and technology is critical. Understanding our contributions to outcomes (modifiable risk) and our ability to perceive and predict an evolving clinical state (low failure-to-predict rate) are important performance metrics. Improved methods for capturing continuous physiologic signals will allow for new and interactive approaches to data visualization, and for sophisticated and iterative data modeling that will help define a patient’s phenotype and response to treatment (precision physiology).

CHD affects millions of patients worldwide. Interventional therapies for CHD goes back to the mid-1960s when Bill Rashkind performed balloon atrial septostomy on a cyanotic baby with transposition of the great vessels. This was followed by development of balloon catheters to perform balloon valvuloplasties and angioplasties in the early to late 1980s. Although King and Mills performed the first transcatheter closure of secundum atrial septal defect in the mid-1970s, this procedure was better realised in the mid-1990s. More intracardiac defect closures were performed in the late 1990s and early 2000. This brings us to the current era of percutaneous valve implantation as developed by Bonhoeffer. In this paper, we will discuss the past, present, and future of interventional cardiac catheterisation for CHD patients.

The Imaging Program at the 7th World Congress highlighted the versatility and diagnostic power of the current and upcoming imaging tools in Pediatric Cardiology and Cardiac Surgery. Several experts presented interesting as well as practical data on the use of 2D and 3D Echocardiography, magnetic resonance imaging and computed tomography in the fetus, child, and adult with congenital heart disease. Bridging sessions coupled use of these imaging modalities and screening practices in patients with acquired heart disease. Hot topics included nomenclature of ventricular septal defects, the challenging diagnosis of double outlet right ventricle, cardiac tumors, and imaging of aortapathies. Several talks concentrated on the quantitative assessment of ventricular function and reviewed numerous exciting new modalities that currently serve as research tools. In summary, Imaging Sessions truly represented how far we have advanced the field of Imaging in Pediatric Cardiology and Cardiovascular Surgery.

The interventional cardiology track at the 7th World Congress of Pediatric Cardiology and Cardiac Surgery reflects the pivotal position of transcatheter interventions in the future of our speciality. The highlights of the week are outlined in this review.

The Seventh World Congress of Pediatric Cardiology was held in Barcelona in July, 2017. The central philosophy of the congress was “bridging together” all major specialties in the field. This article summarises the highlights of the meeting as it relates to ambulatory paediatric cardiology. There is a now a more unified approach to children with CHD, including assessment of neuro-developmental outcomes. The new World Heart Foundation criteria for the diagnosis of rheumatic fever remain controversial.

The seventh meeting of the World Congress of Pediatric Cardiology and Cardiac Surgery was an opportunity for healthcare professionals from around the world to meet and discuss current issues affecting patients with acquired and CHD. A dedicated anaesthesia track facilitated the exchange of ideas and fostered many new friendships. This review highlights the congenital cardiac anaesthesia track and the involvement of the Congenital Cardiac Anesthesia Society in the congress.

The heart failure, heart transplantation, and pulmonary hypertension workgroups of the Scientific Committee were honoured to be asked to plan a full slate of sessions at the 2017 World Congress of Pediatric Cardiology and Cardiac Surgery. In all there were 35 oral platform presentations, a further 14 oral platform presentations in “Bridging Together” sessions with other workgroups/specialties, a terrific debate about transplant listing in adult CHD patients, and a further 23 oral abstract presentations. The speakers were clear and concise, the research presented was ground-breaking, and the global representation was evident.

The 2017 Seventh World Congress was held in Barcelona, Spain, 16–21 July. The week in review for this meeting is presented in the current issue of Cardiology in the Young, and herein we discuss the surgical highlights of the programme.

For the first time in 2017 adults with CHD was included in the World Congress of Pediatric Cardiology & Cardiac Surgery. With growing numbers and more complex patients reaching adulthood, there is a growing need for more attention to this subspecialty. Although survival is excellent and now over 90% of patients reach adulthood, many have residual problems and complications. Heart failure and arrhythmias are most commonly encountered. Life-expectancy is nearly normal for mild lesions, but remains reduced in moderate-complex lesions and re-interventions are often needed. As most patients want to live a normal life, sports participation and pregnancy become very important issues. Finally, although innovative treatments are being developed, including for end-stage heart failure, we have to refine strategies for optimal care, including during the end-stage lives of our patients. This article provides an overview of a selection of topics in the field of adults with CHD presented during the 2017 Seventh World Congress of Pediatric Cardiology & Cardiac Surgery (WCPCCS) in Barcelona.

In this report, the authors prepared an opinion poll regarding the most important people, events, technologies, concepts, discoveries, and therapies in paediatric cardiology and cardiac surgery. The results were presented in continuous slide show format at the 2017 Seventh World Congress of Pediatric Cardiology & Cardiac Surgery (WCPCCS 2017), Barcelona, Spain.
