Mechanical circulatory support in high-risk percutaneous coronary intervention

High-risk percutaneous coronary intervention involves technical challenges in performing revascularization, hemodynamic instability and heart rate variability, and possible complications. Mechanical circulatory support devices ensure hemodynamic stability and expansion of opportunities for revascularization. Current methods include the following devices: intra-aortic balloon counterpulsation, Impella, TandemHeart, and venoarterial extracorporeal membrane oxygenation. The review accumulates current evidences on the use of these devices for mechanical circulatory support during high-risk percutaneous coronary intervention from the reports, registries, randomized and observational studies, as well as clinical trials.
