What are the clinical features and treatment options for Transposition of Great Arteries (TGA)?
* Transposition of Great Arteries (TGA) is the most common cyanotic heart disease.
* The aorta emerges from the right ventricle and the pulmonary artery from the left ventricle.
* The foramen ovale allows partial mixing of blood after birth, ensuring initial survival.
* When the foramen ovale closes, the child dies.
* Clinical features include absence of murmur, cyanosis, hypoxia, tachypnea, and metabolic acidosis.
* Treatment options include continuous infusion of prostaglandin E1 to keep the ductus arteriosus open, atrial septostomy with a balloon to allow flow, and arterial inversion surgery (Jatene surgery) in the first weeks of life.

A Transposição das Grandes Artérias (TGA) é uma doença cardíaca cianótica congênita. Suas características clínicas incluem ausência de sopro cardíaco, cianose, hipóxia, taquipneia e acidose metabólica. O tratamento para TGA envolve a infusão contínua de prostaglandina E1 para manter o ducto arterioso aberto, a realização de septostomia atrial com balão para permitir o fluxo sanguíneo e a cirurgia de inversão arterial (cirurgia de Jatene) nas primeiras semanas de vida.
