Back   Figure 9A. Selective angiogram in the patent ductus of a three week old patient who presented with severe cyanosis. The ductus arises from an anomalous left subclavian artery in this patient with a right aortic arch. It supplies the entire left pulmonary artery. At presentation at three weeks of age the ductus was nearly closed and did not respond to prostaglandin. The patient had a stenotic MAPCA to the right lung and saturations in the 40’s.  B. Following emergent balloon dilation of the ductus, saturations increased into the 70’s. A left modified BT shunt was placed ten days later and the ductus was ligated.     Back www.impaedcard.com
