Transposition of the great arteries: the importance of new strategies for rapid diagnosis

Abstract

Transposition of the Great Arteries (TGA) is considered the predominant cyanotic congenital heart disease (CHD) of the neonatal period, accounting for 5-9% of cardiac malformations. In TGA, the ventriculo-arterial connection is considered discordant, as the ascending aorta arises abnormally from the morphological right ventricle and the pulmonary artery arises abnormally from the morphological left ventricle, connected to the pulmonary trunk (YELBUZ et al., 2018). Therefore, the systemic and pulmonary circulations are in parallel rather than in series, causing oxygen-poor blood to circulate through the body and oxygenated blood to circulate through the lungs (SÉGUÉLA et al., 2016).
