A significant MVG is commonly seen in patients with severe calcific aortic stenosis and is associated with higher pulmonary arterial and left atrial pressures.
Among patients with acute myocardial infarction (AMI), those in cardiogenic shock have the highest mortality rate. Early revascularisation with primary percutaneous intervention or coronary artery bypass surgery has decreased the mortality rate of patients in cardiogenic shock, but it remains high. The conventional treatment of haemodynamic instability has been the use of the intra-aortic balloon pump (IABP); however, the IABP may not give adequate support to patients with severe left ventricular dysfunction. Recent advances in percutaneous left ventricular assist devices, specifically the TandemHeart and Impella LP 2.5, have shown improved haemodynamic support compared with the IABP. This article provides an overview of the use of percutaneous left ventricular assist devices to treat patients presenting with cardiogenic shock after acute MI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
