Introduction: Temporary mechanical circulatory support (MCS) is a common supportive therapy in cardiogenic shock and high-risk coronary intervention. The proliferation of new percutaneous MCS devices allows support to be instituted rapidly without surgical cutdown. The recent literature exploring the indications, benefits, and risks of each is reviewed. Areas discussed: Current applications of percutaneous MCS devices, including intra-aortic balloon pumps (IAPB), Impella, TandemHeart, and VA ECMO are discussed. Studies investigating each were identified through a combination of online database queries and direct extraction of single studies cited in previously-identified papers. Information on unpublished trials and registries was found on ClinicalTrials.gov. Expert commentary: Direct VADs provide a higher level of hemodynamic support compared to IABP and their early use will continue to expand. The development of percutaneous RV support systems may allow more patients to receive such therapy faster. VA ECMO is being used increasingly in CPR and in outreach programs.
