A patient is seen in the emergency department for a myocardial infarction and cardiogenic shock. The physician assesses the patient for contraindications to an intra-aortic balloon pump (IABP). Which of the following is an absolute contraindication?
• The IABP works by inflating a balloon inside the descending aorta during diastole to displace blood and increase perfusion to the organs. During systole, the balloon rapidly deflates, reducing aortic volume through a vacuum effect and lessening the workload of the heart
• Absolute contraindications to an IABP include significant aortic
• The other absolute contraindication is aortic
• Incorrect: AAA and peripheral arterial disease are relative contraindications, and an IABP can be used with caution. Vascular complications are the major risk associated with its use
• Incorrect: A hypertensive crisis is not a contraindication to an IABP
