Issues with carotid stenosis detection by ultrasound in patients with left ventricular assist devices

The study by Kronfli et  al1 was a small retrospective study of patients using a left ventricular assist device (LVAD) who had undergone carotid duplex ultrasound evaluation. Given the increasing utility of LVADs and their hemodynamic effects, it seems prudent to study the criteria for arterial stenosis in such patients. It was observed that the peak systolic velocity was decreased and the end-diastolic velocity and velocity ratios were increased. There were also three different flow pumps: 21 with axial flow, 13 with centrifugal flow, and 2 with pulsatile flow.
