Description
A 3-day-old full-term neonate, born by normal vaginal delivery, was presented with respiratory distress and mild cyanosis. His room air saturation in all four limbs was 84%. The clinical examination was unremarkable. Chest X-ray showed cardiomegaly and increased pulmonary vascular markings. Transthoracic echocardiography revealed 8 mm ostium secundum atrial septal defect (ASD) with bidirectional shunt and dilated right atrium and right ventricle with absence of individual pulmonary veins (PV) draining into left atrium (LA). Suprasternal view showed vertical vein (VV) which was recognised as a vessel lateral to LA with red-coloured continuous flow on Doppler (figure 1). The PVs were draining into the venous confluence behind the LA which was draining into the VV. VV connects into the left innominate vein which finally forms the right superior vena cava (figure 1, video 1).
