Rapid progression of carotid artery atherosclerosis and stenosis in a patient with a ventricular assist device.

This case describes the management of cerebrovascular disease in a patient with a left ventricular assist device (LVAD) who was awaiting cardiac transplantation. It demonstrates several unique features in managing vascular disease in patients with cardiac assist devices. First, we detail the difficulties in using duplex ultrasound to assess patients with altered hemodynamic physiology. Second, we report an instance of rapid progression of known carotid stenosis in a patient with a recently placed LVAD. This case suggests that patients with any degree of carotid stenosis before LVAD placement should be monitored closely for progression after the LVAD is placed.
