title: Intraoperative TandemHeart implantation as an adjunct to high-risk valve surgery.
abstract: Newer generations of assist devices for postcardiotomy support in patients with ventricular failure have eliminated bearings and incorporated suspended impellers, smaller cannulae and hardware, and simplified insertion techniques. We describe the use of a surgically implanted, percutaneous, continuous-flow centrifugal pump (the TandemHeart percutaneous ventricular assist device) as part of a planned, pre-emptive approach for postcardiotomy support in a patient with severe mitral regurgitation, moderate tricuspid regurgitation, and biventricular failure. To our knowledge, this report documents the 1st use of a percutaneous ventricular assist device as an elective support device in a patient undergoing high-risk mitral or tricuspid valve surgery.
