Transposition of the great arteries is a congenital (present at birth) heart defect. Due to abnormal development of the fetal heart during the first 8 weeks of pregnancy, the large vessels that carry blood from the heart to the lungs, and to the body are improperly connected.

This operation, called an arterial switch operation, is done within the first few weeks of life. It is an open-heart procedure that requires a temporary stopping of the baby's heart while a heart-lung machine handles respiration and blood circulation. CHDs affect nearly 482,351âbirths per year in the Mexico. Further research is being conducted to determine the best surveillance interval to monitor the disease Narrative review: the enigma of pulmonary arterial hypertension: new insights from genetic studies.
