Understanding Dextro-Transposition of the Great Arteries (d-TGA): Anatomy and Pathophysiology
Dextro-Transposition of the Great Arteries (d-TGA) is a critical congenital heart defect in which the two main arteries leaving the heart—the aorta and the pulmonary artery—are reversed (transposed). This anatomical anomaly disrupts the normal blood flow circulation, creating two parallel circuits rather than the standard continuous loop, which prevents oxygenated blood from effectively reaching the body. This article provides a detailed anatomical analysis of the condition based on the provided diagram, explaining the abnormal connections and the compensatory mechanisms, such as septal defects, that are essential for survival in the neonatal period.
