Risk Factors for Development of Stroke in Patients With Continuous-Flow Left Ventricular Assist Device Support as Destination Therapy [PDF]

Texas Heart Institute Journal
Background: Continuous-flow left ventricular assist devices (LVADs) are increasingly used as destination therapy. Although postimplantation stroke rates have been described in the context of bridge-to-transplant or mixed cohorts, stroke development is ...
