Complete Unbalanced Atrioventricular Septal Defect With a Common Arterial Trunk in an Uncontrolled Type I Diabetic Mother: A Case of Diabetic Embryopathy

摘要

When performed by a trained sonographer, fetal echocardiography can be instrumental in identifying cardiac pathology and abnormal cardiac physiology before a baby is born. Even though the diagnostic accuracy of a fetal echocardiogram can be limited by maternal body habitus, gestational age, and fetal position, sequential exams allow for detailed analysis of the cardiac structures. Early identification and diagnosis of intrauterine cardiac anomalies and subsequent pregnancy management and delivery planning are essential to providing the best possible outcome for fetuses born with heart defects. In this case study, we describe a rare combination of congenital heart defects diagnosed in an uncontrolled type I diabetic mother while in her second trimester of pregnancy.
