Figure 2 Computed tomographic angiography findings of the heart and great vessels(A) Definitive diagnosis of Berry syndrome. The aorta originates from the left ventricle, giving rise to the brachiocephalic artery, left common carotid artery, and left subclavian artery. The ascending aorta inner diameter is 7.4 mm. The aortic arch is interrupted distal to the left subclavian artery, with a local connection between the ascending aorta and pulmonary trunk. The defect spans approximately 7.7 mm. (B) After first-stage corrective surgery for Berry syndrome. The aortopulmonary window has been separated. The descending aorta anastomotic site is relatively narrow, with an inner diameter of approximately 5.3 mm. Right heart enlargement with right ventricular wall thickening is present. The anastomotic site between the right pulmonary artery and main pulmonary artery remains patent. The right pulmonary artery shows stenosis, with the narrowest point measuring approximately 1 mm.
