The anteroposterior relationship of aorta and pulmonary artery and thymic hypoplasia contribute to the narrow pedicle in infancy in dextro transposition of great arteries. Some also call it &#8216;egg on string&#8217; appearance to account for the narrow pedicle.<\/p>\n<p>In a case reported by Varal et al, a baby admitted to neonatal intensive care unit with severe respiratory distress, cyanosis and a short systolic murmur had X-ray chest showing \u201cegg on a string\u201d sign [2]. Emergency echocardiography and cardiac catheterisation confirmed the diagnosis of D-TGA. Prostaglandin E1 infusion to maintain ductal patency followed by arterial switch operation was planned. Authors mentioned that the \u201cegg on a string\u201d sign may be seen on chest X-ray in around one third of patients with D-TGA.<\/p>\n<p>It may be noted the X-ray appearance in congenitally corrected transposition is entirely different from that of dextro transposition of great arteries. Congenitally corrected transposition is also called levo transposition of great arteries because of the levoposed aorta. Levo posed aorta is seen as a bulge along the left upper border of the heart [3].<\/p>\n<p><strong><span style=\"color: #0000ff;\">References<\/span><\/strong><\/p>\n<ol>\n<li>Michael W.
