Perioperative intra‑aortic balloon counterpulsation in a patient with myocardium at risk undergoing urgent noncardiac surgery.

We are presenting the case of a 76‑year‑old female scheduled for major abdominal surgery. Her past medical history was remarkable for a three‑vessel coronary artery disease, with a severely impaired left ventricular function. She had already undergone complex coronary artery bypass surgery. Currently, she presented with the rare constellation of a hemodynamic relevant and interventionally intractable stenosis of the left subclavian artery proximal to a crucial coronary bypass from left internal mammary artery to the left anterior descending. To protect this patient from perioperative myocardial infarction, an intra‑aortic balloon pump was successfully used.
