Once considered a childhood disease, the number of adults living with congenital heart disease (CHD) has now exceeded the number of pediatric patients. The landscape of percutaneous intervention for adult congenital heart disease (ACHD) has evolved over the past decade and has yet to be characterized in Canada. The aim of this study was to begin to understand the current infrastructure underlying ACHD interventions in Canada and to characterize the type and number of interventions being carried out across the country. A cross-sectional national survey was distributed by e-mail to all cardiac catheterization laboratory directors in 2015. All Canadian laboratories involved in ACHD interventions responded, encompassing 19 institutions spanning 69 cardiac catheterization laboratories. A total of 1451 percutaneous interventions were recorded. Nationwide, the most common simple ACHD interventions were for atrial septal defect and patent foramen ovale closures. The most common ACHD interventions of increased complexity were for coarctation stenting and transcatheter pulmonary valve implantation. There was a marked clustering of procedures in Ontario, Québec, British Columbia, and Alberta in keeping with Canada's population-density distribution. A total of 23 ACHD operators were identified, half of whom had ACHD-specific fellowship training. These data can be used as a starting point to inform the present state of affairs in the area and lay the groundwork for further work to assess resource allocation and human resource planning for the care of patients with ACHD in Canada.
