Abstract
Percutaneous mechanical circulatory support devices (PMCSD) consist of the intra-aortic balloon pump (IABP), Impella (Abiomed Inc., Danvers, Massachusetts), Tandem Heart (Cardiac Assist, Inc., Pittsburgh, Pennsylvania), or extracorporeal membranous oxygenation (ECMO). They augment cardiac output, cardiac index, and cardiac power which allow the operator to mitigate hemodynamic perturbations during high-risk percutaneous coronary intervention (HR-PCI). This review discusses PMCSD and their contemporary literature. Recent literature has substantiated the hemodynamic benefits of PMCSD in HR-PCI and cardiogenic shock, but no mortality benefit was found. As stent technology improves, PCI is expanding into high-risk cases in which PMCSD provide hemodynamic support allowing safe and complete revascularization.
