Six infants underwent angiography of the aortic root and the descending aorta with balloon inflation during diagnostic cardiac catheterisation and angiography. In these infants with large proximal left to right shunts, descending aortography with balloon inflation resulted in better opacification of the persistent ductus arteriosus than aortic root angiography, thereby enabling accurate measurement of the persistent ductus arteriosus. Similar systemic and pulmonary vascular impedances had been speculated as the cause of poor or non-opacification of the ductus after ascending aortography. Balloon inflation may have altered the aortic impedance with resulting opacification of the ductus. Descending aortic angiography with balloon inflation is also useful in opacifying the isolated ductus and in demonstrating aortopulmonary collaterals in patients with pulmonary atresia.
6例婴儿在诊断性心导管插入术和血管造影期间接受了主动脉根部和降主动脉血管造影，并进行了球囊扩张。在这些存在大的近端左向右分流的婴儿中，球囊扩张的降主动脉造影比主动脉根部造影能更好地使动脉导管显影，从而能够准确测量动脉导管。曾推测升主动脉造影后动脉导管显影不佳或不显影的原因是体循环和肺循环血管阻力相似。球囊扩张可能改变了主动脉阻力，从而使动脉导管显影。球囊扩张的降主动脉造影在使孤立的动脉导管显影以及显示肺动脉闭锁患者的主肺动脉侧支方面也很有用。
