Considerable progress has been made over the last decades in the diagnosis and treatment of congenital heart disease (CHD) and over 90% of the children born with this condition are expected to survive into adulthood in the current era. This has created a substantial population of patients with adult congenital heart disease (ACHD). As the population of ACHD continues to expand rapidly, so does the potential for transcatheter interventions in this patient population.

Transcatheter interventions for CHD has dramatically evolved over the past three decades to provide definitive treatment to some of the most frequent CHDs such as atrial septal defects, patent ductus arteriosus with nearly 100% early and late survival. More complex procedures such as valve implantation and various types of stenting have emerged to provide additional alternatives to cardiac surgery and many of these complex patients will need subsequent interventions throughout their lives. In addition, the similar interventional techniques used for CHD are applied to treat other acquired cardiac conditions such as paravalvular leak closure or the more recent implantation of atrial flow reducer in patients with cardiac failure. Finally, new scientific evidence for the closure of patent foramen ovale after cryptogenic stroke will further increase the interventional program in ACHD units.
