The<unk>  is a percutaneously inserted ventricular assist device (pVAD) that is used to temporarily support left or right ventricular function in patients with cardiogenic shock complicating acute myocardial infarction who undergo high-risk percutaneous coronary intervention (PCI) or open heart surgery. Cardiogenic shock occurs in approximately 6% to 12% of patients with STEMI and 17% of patients with NSTEMI. In these patients, cardiogenic shock results in a 30% to 50% in-hospital mortality after the ischemic event. pVADs utilize a small mechanical pump to give short term support to the ventricles. pVADs aim to improve outcomes through three primary mechanisms: (1) increase the mean arterial pressure (2) reduce in ventricular diastolic pressure (3) increase in coronary perfusion.
