Conclusion
The ideal device generates sufficient haemodynamic support to prevent end-organ failure, but also myocardial protection to prevent myocardial ischaemia and has a low complication rate. The experience and usage of percutaneous cardiac assist devices in CS as well as high-risk PCI has increased over the past years. However, there is still little evidence of clinical benefit of these invasive devices and it is important that they prove their clinical benefit before they become common clinical practice.
