Central and peripheral blood flow during exercise with a continuous-flow left ventricular assist device: constant versus increasing pump speed: a pilot study.
BACKGROUND End-stage heart failure is associated with impaired cardiac output (CO) and organ blood flow. We determined whether CO and peripheral perfusion are maintained during exercise in patients with an axial-flow left ventricular assist device (LVAD) and whether an increase in LVAD pump speed with work rate would increase organ blood flow. METHODS AND RESULTS Invasively determined CO and ...

متن کاملBlood pressure and adverse events during continuous flow left ventricular assist device support.
BACKGROUND Adverse events (AEs), such as intracranial hemorrhage, thromboembolic event, and progressive aortic insufficiency, create substantial morbidity and mortality during continuous flow left ventricular assist device support yet their relation to blood pressure control is underexplored. METHODS AND RESULTS A multicenter retrospective review of patients supported for at least 30 days and...
متن کاملLate Complications Following Continuous-Flow Left Ventricular Assist Device Implantation
Left ventricular assist devices have become standard therapy for patients with end-stage heart failure. They represent potential long-term solutions for a growing public health problem. However, initial enthusiasm for this technology has been tempered by challenges posed by long-term support. This review examines these challenges and out current understanding of their etiologies.
متن کاملApical pseudoaneurysm following continuous flow left ventricular assist device placement.
The HeartMate II continuous flow left ventricular assist device (LVAD) (Thoratec Inc) provides circulatory support for patients with medically refractory systolic heart failure as both a bridge to transplantation and destination therapy. Although left ventricular apical pseudoaneurysm has rarely been reported with first-generation pulsatile flow LVADs, this has not been previously reported with...
