Esophageal stenosis due to vascular ring.

a E u s a o 6-year-old boy was referred for follow-up of a ventricular septal defect, which was first diagnosed when he was a neonate. Cardiac catheterization performed t 7 months of age revealed an aberrant left subclavian artery rising from the right aortic arch. Recurrent respiratory inection that caused stridor and/or wheezing occurred in early nfanthood, but it was deemed not related to the cardiac efect because the pulmonary-to-systemic flow ratio was 1.6:1 nd there was no pulmonary hypertension. With time, his espiratory symptoms remitted, and he was lost to follow-up or several years, while his family worried about his dysphagia. o heart murmur was auscultated, and the second heart ound was split and fixed. Electrocardiography showed inomplete right bundle-branch block. Ultrasonography indiated a small infundibular ventricular septal defect and right entricular volume overload with intact atrial septum. Contrast-enhanced 16-row multislice computed toography was performed, and three-dimensional reconstrucion (Figure 1) visualized anomalous connection of the rightpper pulmonary vein to the superior vena cava (A) and the ight retroesophageal aortic arch with an aberrant left subclaigure 1.
