CONCLUSIONS
Cardiogenic shock due to left main coronary artery thrombosis is rare and associated with high mortality and poor prognosis. Urgent revascularization and hemodynamic support are vital to improving survival. Intra-aortic balloon pumps, which until recently have been the only percutaneously deliverable mechanical support devices, have now been joined by a number of additional percutaneous mechanical circulatory support devices which can provide even greater assistance in cardiac function.
