Despite therapeutic improvements, cardiogenic shock (CS) remains the most common cause of death in patients with acute myocardial infarction (AMI). In addition to percutaneous coronary intervention, inotropes, fluids, adjunctive medication, intra-aortic balloon counterpulsation, and also assist devices are widely used for treatment. However, currently, there is only limited evidence for any of the above treatments. This review will therefore outline the underlying causes, pathophysiology, and treatment of CS complicating AMI with major focus on interventional techniques and advancement of new therapeutical arsenals, both pharmacological and mechanical.

Traumatic injury to the pericardial leaflets does occur during crimping and deployment of balloon- or self-expandable VSs. Injury may be more severe with the balloon-expandable VSs. The impact of such an injury on prosthesis durability requires a further investigation.
