Congenital Heart Defects as One of the Causes of Perinatal Mortality

Congenital malformations are one of the most common causes of infant mortality and disability in children, and congenital heart defects (CHD) occupy a leading place in the structure of all developmental anomalies. The article presents data from a retrospective analysis of charts of children who died from complex congenital heart defects and congenital heart defects in combination with multiple developmental defects. An analysis of the pathological examination cards of 102 children from 0 to 2 years old who died in maternity hospitals and children's hospitals in Bishkek was carried out. The selection of autopsy cards of children was carried out on the basis of the Republican Pathological Bureau. As a result of pathological studies, changes in the heart and lungs were revealed. At the maternity hospital stage, out of 102 children with severe congenital heart defects, 70 newborns died, which averaged 68.6%. Among congenital heart defects, heart defects with aortopulmonary shunting with pulmonary hypertension predominated — in 45 children (44%), in particular, ventricular septal defect, atrial septal defect, then ductus-dependent heart defects were diagnosed in 25 children (24.5%), which included Tetralogy of Fallot, transposition of the great vessels. 23.5% of children had multiple congenital malformations: in all cases, congenital heart disease was recorded in combination with several malformations, such as an anomaly of the musculoskeletal system with craniofacial dimorphism, anomalies of the gastrointestinal tract and urinary system, and an anomaly of the lungs. The most common association of congenital heart disease with defects of other organs and systems was observed in cases of ventricular septal defect, atrial septal defect, patent ductus arteriosus.
