A complication of an axillary intra-aortic balloon pump.

ABSTRACT

Intra-aortic balloon pumps (IABPs) are used to mechanically temporize a failing heart by decreasing afterload while increasing coronary perfusion pressure of the heart while more definitive treatment is sought. We report a case of a 65-year-old male with nonischemic cardiomyopathy, atrial fibrillation, thyroiditis, and non-Hodgkin lymphoma who presented with worsening heart failure. He underwent a percutaneous placement of a left axillary IABP with seemingly no complications. Approximately 3 weeks post-placement, the patient was taken for a heart transplant when an intraoperative transesophageal echo showed that the IABP was in the aortic arch and ascending aorta, instead of its proper placement in the descending aorta. The patient's arterial line showed waveforms appropriate for an IABP patient, and the patient showed no signs indicative of improper placement. This erroneous placement carried the potential to affect the aortic valve function, injure the aortic intima and/or occlude the aortic arch vessels. .
