Abstract

Blood pressure (BP) measurement is challenging among patients with continuous-flow left ventricular assist device (CF-LVAD) due to reduced pulse pressure (PP). Although Doppler opening BP (DOBP) is uniformly obtainable and provides an accurate measure of systolic BP (SBP), it routinely overestimates mean arterial pressure (MAP), particularly among CF-LVAD patients with higher PP. 1,2 The success rate of traditional cuff-based automated BP (ABP) monitors ranges from 50% to 80%, and is highly dependent on PP. 1–3 The HeartMate 3 (HM3, Abbott Labs) is the latest generation CF-LVAD with an improved pump design that resulted in significant reduction in mortality and hemocompatibility-related adverse events, 4 and, eventually, in a monopoly of the market. The HM3 features an artificial pulse which occurs asynchronously from the native.
