Established in October 1991, the Canadian Adult Congenital Heart (CACH) Network was created to pool the knowledge and experience of congenital heart disease professionals in Canada to help strengthen their skills and knowledge of the discipline, and to create a community of individuals committed to caring for adults with congenital heart disease-and their families.

CACH Network received Affiliate Status with the Canadian Cardiovascular Society (CCS) in September 2010. This CCS Affiliate Status integrates CACH Network in the CCS community, provides the opportunity for close collaboration on programs and services to the cardiovascular community and strengthens government relations and public relations (e.g. advocacy, public education activities).
