Complications of Continuous-Flow Mechanical Circulatory Support Devices
Left ventricular assist devices (LVADs), more importantly the continuous-flow subclass, have revolutionized the medical field by improving New York Heart Association (NYHA) functional class status, quality of life, and survival rates in patients with advanced systolic heart failure. From the first pulsatile device to modern day continuous-flow devices, LVADs have continued to improve, but they ...
متن کاملAdvances in Mechanical Circulatory Support Bleeding and Thrombosis in Patients With Continuous-Flow Ventricular Assist Devices
Because of the obligate intravascular location of contemporary continuous-flow ventricular assist devices (CFVADs), it is not surprising that bleeding and thrombosis are among the most common and feared complications of this therapy, respectively. Although strides have been made in our understanding of the pathophysiology of continuous flow, intravascular CF-VADs have been widely used only in t...
متن کاملSimulation of Dilated Heart Failure with Continuous Flow Circulatory Support
Lumped parameter models have been employed for decades to simulate important hemodynamic couplings between a left ventricular assist device (LVAD) and the native circulation. However, these studies seldom consider the pathological descending limb of the Frank-Starling response of the overloaded ventricle. This study introduces a dilated heart failure model featuring a unimodal end systolic pres...
متن کاملMechanical Circulatory Support
The role of mechanical circulatory device therapy has progressed rapidly over the last 2 decades, from supporting the failing heart in hospitalized patients awaiting heart transplantation to permanent or “destination” outpatient therapy in individuals with end-stage systolic heart failure (HF) for whom transplantation is not an option. Over this period, devices themselves have evolved through s...
متن کاملPediatric Mechanical Circulatory Support
Mechanical circulatory support (MCS) in the pediatric heart failure population has a limited history especially for infants, and neonates. It has been increasingly recognized that there is a rapidly expanding population of children diagnosed and living with heart failure. This expanding population has resulted in increasing numbers of children with medically resistant end-stage heart failure. T...
