Congenital heart disorders (CHD) cause 0.8% of live births, but during the past few decades, technological advancements and widespread repair have boosted the number of newborns who survive into adulthood—more than 95% now. Although late complications such as cardiovascular disease, hypoxemia (PH), arrhythmias, aneurysms, and endocarditis developed often, they had a significant negative influence on mortality and morbidity. Significant advancements have been achieved in the diagnosis process through the utilization of MRI, biomarkers, and e-health ideas, including the simulation of anatomy. With a continued focus on education and the establishment of weekly interdisciplinary consultations, care is now centralized in specialized centers on examination and treatment. The burden of congenital abnormalities has been significantly diminished by the use of innovative ideas in cardiac surgery and percutaneous treatments.
