Diagnostic yield, clinical and demographic factors, and testing trends over time were evaluated. Surveys were sent to parents of children who had met a clinical geneticist (n=112).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Genetic testing was completed in 607 individuals (74 molecular testing; 533 cytogenetic testing only). The diagnostic rate was 36% and 9%, respectively. Use of molecular testing significantly increased over time (p=0.033), but yield did not (p=0.288). Molecular testing yield was high in neonates (64%), and patients with extracardiac anomalies (40%) or relevant family history (40%). Brain (p=0.022), haematological\/cancer (p\u22640.001), immune (p\u22640.001), endocrine (p\u22640.001) anomalies and intellectual disability (p=0.027) were associated with a diagnosis following cytogenetic testing. Short stature was significantly associated with diagnostic yield following molecular testing (p=0.012). Survey respondents (n=28) reported a positive experience (p=0.013) with minimal decisional regret (p=0.322).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Cytogenetic testing remains an important first-tier test in CHD.
