Jarvik 2000 biventricular assist device conversion from old pin-shaped bearing pumps to new conical bearing pumps

摘要

A patient with a Jarvik 2000 (Jarvik Heart, Inc., New York, NY) biventricular assist device had massive hemolysis and device insufficiency of the right ventricular assist device (RVAD) after the anticoagulation was temporarily reversed due to cerebral hemorrhage. After the patient's condition was stabilized by bridge use of CentriMag (Levitronix LLC, Waltham, MA) for right ventricle support, the Jarvik 2000 pumps with pin-shaped bearings were exchanged with new conical bearing pumps. Examination of the removed pumps revealed tight thrombus formation around the pin-shaped bearings.
