Enhancement of Arterial Pressure Pulsatility by Controlling Continuous-Flow Left Ventricular Assist Device Flow Rate in Mock Circulatory System
Continuous-flow left ventricular assist devices (CF-LVADs) generally operate at a constant speed, which reduces pulsatility in the arteries and may lead to complications such as functional changes in the vascular system, gastrointestinal bleeding, or both. The purpose of this study is to increase the arterial pulse pressure and pulsatility by controlling the CF-LVAD flow rate. A MicroMed DeBake...

متن کاملArterial Pulsatility and Aortic Valve Function under Continuous Flow Left Ventricular Assist
Continuous Flow Left Ventricular Assist Devices (CF-LVADs) generally operate at a constant speed, which causes a decrease in pulse pressure and pulsatility in the arteries and allegedly may lead to late complications such as aortic insufficiency and gastrointestinal bleeding. The purpose of this study is to increase the arterial pulse pressure and pulsatility while obtaining more physiological ...
متن کاملPulsatility and the risk of nonsurgical bleeding in patients supported with the continuous-flow left ventricular assist device HeartMate II.
BACKGROUND Bleeding is an important cause of morbidity and mortality in patients with continuous-flow left ventricular assist devices (LVADs). Reduced pulsatility has been implicated as a contributing cause. The aim of this study was to assess the effects of different degrees of pulsatility on the incidence of nonsurgical bleeding. METHODS AND RESULTS The Utah Transplantation Affiliated Hospi...
متن کاملApical pseudoaneurysm following continuous flow left ventricular assist device placement.
The HeartMate II continuous flow left ventricular assist device (LVAD) (Thoratec Inc) provides circulatory support for patients with medically refractory systolic heart failure as both a bridge to transplantation and destination therapy. Although left ventricular apical pseudoaneurysm has rarely been reported with first-generation pulsatile flow LVADs, this has not been previously reported with...
