High-Output Mechanical Circulatory Support in Left Main Interventions: The Magenta Elevate High-Risk PCI First-in-Human Study.

Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA. Electronic address:
Background: The Magenta Elevate is a 9-F, self-expanding, catheter-mounted pump delivered sheathed through a commercially available 10-F femoral introducer over the wire to the left ventricle (LV), providing temporary hemodynamic support up to an equivalent of normal cardiac output.
Objectives: The authors sought to assess the feasibility and outcomes of Elevate-supported high-risk percutaneous coronary intervention (HR-PCI) in a first-in-human study and study the hemodynamic impact of high-output support during prolonged interventional left main coronary artery (LM) occlusions.
Methods: In this study, 14 patients underwent Elevate-supported HR-PCI, with 8 patients undergoing 20 prolonged (39 ± 16 seconds) balloon occlusions of an unprotected LM.
