Their screening was randomized to equal females/males with not known previous obstetric alert regarding CHD. Scanning was done by two teams of pediatric cardiologists by using echo-2D. Each team was ‘blinded’ to the findings of each other. All scans were recorded, and a third senior physician reevaluated them.</p><p><strong>Results</strong>: From 2570 term neonates of the general population, they detected 47 CHD’s. From them, 17 were critical and severe-CHD and 7/47(14.9%) were &nbsp;of moderate complex. 17/47 (36.2%) were cyanotic and 30/47(63.8%) were non-cyanotic. The incidence of simple CHD was 25/47(53.2%). Analysis of the specific anatomy is presented in table1. The estimated incidence was 1.83%. &nbsp;As this incidence has been among the highest reported a post hoc analysis has clarified and presented an important clinical rate of 1.48% after redacting minimal defects without any clinical significance, as minor PDA’s, ASD II, VSD’s. A post hoc calculation of BAov, revealed an anatomical BAov incidence of 1.65% and a functional BAov incidence of 1.4%.</p><p><strong>Conclusions:</strong> This first-ever prospective epidemiology study in Azerbaijan involving a cohort equal to 1.65% of the annual living births of the country, estimated a high incidence of CHD. This is among the highest reported globally. &nbsp;The amount of critical and severe CHD after the post hoc analysis increased from 46.8% to 55.3%. The incidence of cyanotic CHD after the post hoc analysis increased from 36.2% to 42.1%. &nbsp;These high numbers are possibly related to an isolated population and conjugated marriage customs of the country. As this represented a state population health burden a post hoc analysis based on clinical important CHD minimized the calculated index nearby 20%.</p> ER -
