Intraoperative transesophageal echocardiographic images. a Midesophageal four-chamber view demonstrating tricuspid atresia, a hypoplastic right ventricle, and VSD. b Midesophageal right ventricle inflow–outflow view using color Doppler imaging demonstrating pulmonary stenosis that caused a dissipative flow in the main pulmonary artery before BTS. c Midesophageal ascending aortic short-axis view using color Doppler imaging demonstrating an antegrade flow from the completely severed main pulmonary artery to both the right and left pulmonary arteries due to BTS, which connected the brachiocepharic artery to the main pulmonary artery. d, Midesophageal ascending aortic short-axis view demonstrating the retrograde flow from the right pulmonary artery to the left pulmonary artery due to the BCPS, which connected the superior vena cava to the right pulmonary artery
