Malposition of axillary IABP. AP chest radiograph with contrast limited adaptive histone equalization (CLAHE) filter demonstrating an axillary approach IABP (a, b). The IABP is malpositioned with the upper marker in the brachiocephalic artery (white arrow on image a). The black arrow indicates the location of the sheath. The inflated balloon is seen in the aortic arch and upper descending aorta. The inferior marker is within the descending aorta (dashed arrow). b AP chest radiograph after attempted advancement of the IABP, the superior marker is malpositioned and is now in the ascending aorta (white arrow). The inferior marker is in the descending aorta (dashed arrow). (IABP = Intra-aortic balloon pump, CLAHE = Contrast limited adaptive histone equalization)
