Use of mechanical circulatory support in high-risk percutaneous coronary interventions.

As the field of percutaneous coronary intervention grows in volume, expertise, and available tools, interventional cardiologists are increasingly performing more complex and higher-risk coronary artery procedures. Mechanical circulatory support devices, previously used only in urgent situations, are now being utilized as supplementary tools to enhance outcomes in elective complex cases. This shift has sparked significant discussions about patient and device selection, as well as the potential risks involved. In this article, we explore the various devices and their distinct features. Additionally, we also introduce algorithms for device selection, placement and weaning to help guide physicians during their care for their high-risk PCI patients.
