title: Current status of percutaneous right ventricular assist devices: First-in-man use of a novel dual lumen cannula.
abstract: Ventricular assist devices have become an accepted therapeutic solution for patients with severe left ventricular dysfunction when pharmacology fails to maintain sufficient cardiac output. Despite various technologies that have allowed left ventricular assist devices to become more reliable and versatile in the past decade, comparatively little attention has been applied to right heart assistance which is still in the early stage of its development. The extracorporeal devices developed thus far have been associated with mobility issues and complications common to ventricular assist devices in general, such as infection, bleeding, and thromboembolism. Designed to obviate the problems previously experienced by other right ventricle (RV)-focused devices, the Protek Duo (CardiacAssist, Pittsburgh, PA) is a novel, fully percutaneous, dual lumen cannula for RV support used in conjunction with the paracorporeal TandemHeart(®) (CardiacAssist, Pittsburgh, PA) pump. We describe our initial experience with the Protek Duo cannula in two different clinical scenarios. In addition, we summarize the current percutaneous mechanical support technology for RV assistance and propose modification of current technology to facilitate its application. © 2016 Wiley Periodicals, Inc.
