Comparison of continuous-flow and pulsatile-flow left ventricular assist devices: is there an advantage to pulsatility?
BACKGROUND Continuous-flow left ventricular assist devices (CFVAD) are currently the most widely used type of mechanical circulatory support as bridge-to-transplant and destination therapy for end-stage congestive heart failure (HF). Compared to the first generation pulsatile-flow left ventricular assist devices (PFVADs), CFVADs have demonstrated improved reliability and durability. However, CF...
متن کاملGastrointestinal bleeding with continuous-flow left ventricular assist devices.
Continuous-flow left ventricular assist device (CF-LVAD) insertion is a life-saving procedure that is being increasingly used in patients with advanced heart failure. However, patients with CF-LVADs are at an increased risk of gastrointestinal bleeding (GIB). Bleeding can occur anywhere in the GI tract with lesions being more prevalent in the upper GI tract than in the lower GI tract. The patho...
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 کاملEffects of continuous-flow versus pulsatile-flow left ventricular assist devices on myocardial unloading and remodeling.
BACKGROUND Continuous-flow left ventricular assist devices (LVAD) are increasingly used for patients with end-stage heart failure (HF). We analyzed the effects of ventricular decompression by continuous-flow versus pulsatile-flow LVADs on myocardial structure and function in this population. METHODS AND RESULTS Sixty-one patients who underwent LVAD implantation as bridge-to-transplant were an...
متن کاملEnhancement 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...
