Article Synopsis
  • The reduced pulsatility in patients with continuous-flow left ventricular assist devices (CF-LVAD) like the HeartMate3 (HM3) has been associated with clinical complications, and the device's "artificial pulse" feature is believed to improve outcomes.
  • A study measured arterial pulsatility and flow in 148 participants, finding that HM3 patients exhibited similar pulsatility levels to HeartMate II (HMII) patients while showing enhanced pulsatility transmission to the microcirculation.
  • Results suggest that the artificial pulse is detectable without significant changes in pulsatility, and that future clinical practices for HM3 patients may need to consider these dynamics regarding pump speeds and microvascular flow.

Objective: Carotid distensibility (CD) is a measure of carotid artery elasticity that has been introduced as a risk factor for cardiovascular disease. Information regarding reproducibility of sonographic CD measures is limited. The objective of this study was to evaluate the inter-reader reliability of sonographic measurements of common carotid artery (CCA) diameters and derived metrics of CD.
