Percutaneous ventricular assist device placement during active cardiopulmonary resuscitation for severe refractory cardiogenic shock after acute myocardial infarction.

Cardiogenic shock after acute myocardial infarction is associated with a high mortality rate despite modern reperfusion methods and intra-aortic balloon pump support. For myocardial infarction patients in cardiogenic shock that is refractory to intra-aortic ballon pump counterpulsation and pressors (severe refractory cardiogenic shock), there are limited means to rapidly provide additional hemodynamic support. We present the case of a 49-year-old man who presented with an anterior wall acute myocardial infarction complicated by cardiogenic shock. After resuscitation and stabilization with intra-aortic balloon pump and pressor support, the patient underwent successful emergent percutaneous transluminal coronary angioplasty and stenting of the left anterior descending coronary artery. Forty-eight hours later, the patient again went into severe refractory cardiogenic shock; pulseless electrical activity arrest followed. Cardiopulmonary resuscitation was started, and the patient underwent urgent placement of a TandemHeart percutaneous ventricular assist device. The device enabled the reversal of terminal hemodynamic collapse during active cardiopulmonary resuscitation, subsequent stabilization of the patient, and discharge of the patient from the hospital after device removal. In this patient, the percutaneous ventricular assist device was successful in the treatment of severe refractory cardiogenic shock after acute myocardial infarction.
