Blood pressure and stroke risk in left ventricular assist devices
Ischemic and hemorrhagic stroke are one of the most devastating outcomes arising from treatment of end-stage congestive heart failure with a left ventricular assist device (LVAD)1. Stroke after LVAD is associated with increased risk of mortality and is a leading cause of not qualifying for transplantation. The risk of stroke is one of many factors limiting more widespread adoption of this technology for end-stage heart failure. The risk factors for stroke in LVAD have been the subject of several studies, with recent infection2 and changes in anti-thrombotics being commonly found3.

Carotid Artery Blood Flow and Its Association with Stroke during Left Ventricular Assist Device Support
Left ventricular assist device (LVAD) surgery is a life-prolonging therapy for advanced heart failure (HF). Despite many improvements over the years, LVADs continue to be associated with a high incidence of stroke and other vascular complications such as gastrointestinal bleeding (GIB). At present, the pathogenesis of these complications during LVAD support remains unclear. Abnormal structure and hemodynamics in large arteries are a potential contributor. We hypothesized that structural abnormalities and flow alterations will be significantly associated with stroke and a composite outcome of stroke, GIB, and death in HF pa...

Different Risk Factors for Ischemic and Hemorrhagic Stroke on Continuous Flow Left Ventricular Assist Device Support
Patients with end-stage heart failure on left ventricular assist devices are predisposed to stroke. Preoperative factors associated with increased stroke risk are poorly understood.

Stroke and Survival Outcomes in Left Ventricular Device Patients
Left ventricular assist devices (LVADs) are artificial pumps used for hemodynamic support in patients with end stage heart failure. They can function effectively as a bridge to transplant as well as extend and improve the quality of life of patients. However, these patients are still at a higher risk of stroke, death, and other complications than the average population.

Carotid-bulb thrombus and continuous-flow left ventricular assist devices: A novel observation
The continuous-flow left ventricular assist device (LVAD) has emerged as a clinically important treatment strategy for patients with advanced-stage heart failure. However, LVADs are not without associated neurologic complications, including stroke. In one review, the incidence of stroke (both ischemic and hemorrhagic) with the HeartMate II (HM II; Thoratec, Pleasanton, CA) ranged from 2% to 18%. In another recent single-center study, the incidence was 10%. In that study, previous stroke, persistent malnutrition and inflammation, severity of heart failure and post-LVAD infections were associated with neurologic complications.

The Impact of Statin Therapy on Neurological Events Following Left Ventricular Assist System Implantation in Advanced Heart Failure
Stroke is a leading cause of disability and death in advanced heart failure patients supported with continuous-flow left ventricular assist systems (CF-LVAS). Statins (HMG-CoA Reductase Inhibitors) reduce the risk of major cardiovascular and neurological events, such as stroke, but their impact has not been evaluated in patients implanted with CF-LVAS. We sought to explore the association between use of statin therapy and subsequent occurrence of neurological events, particularly stroke, following CF-LVAS implantation.

4D Flow MRI in 3D Printed Models of Aorta Grafted With a Ventricular Assist Device Allows Detailed Embolic Trajectory Analysis
Embolic stroke remains an important source of morbidity and mortality in heart failure patients treated with Ventricular Assist Devices (VADs). Decreasing the probability of cranial versus descending aortic embolic trajectory by optimizing the VAD outflow graft position and terminal curvature angle could reduce embolic stroke risk. The goal of this study is to investigate particle trajectories released by a VAD into the aorta, and the effect changes in outflow graft insertion site and terminal curve have on those trajectories.

Natural Antibodies and Left Ventricular Assist Device Complications
Left ventricular assist devices (LVAD) are widely used as a bridge to heart transplantation or destination therapy for advanced heart failure. However, hemocompatibility-related complications such as pump thrombosis, stroke and bleeding remain frequent. We previously reported that LVAD implantation is followed by a sharp increase in serum levels of IgG natural antibodies (Nabs) recognizing oxidation-specific epitopes (OSE). Nabs have been implicated in inflammatory reactions related to atherosclerosis, ischemic stroke and primary graft dysfunction following heart transplantation.

A longer waiting game: Bridging children to heart transplant with the Berlin Heart EXCOR device—the United Kingdom experience
Conclusions: BH use in the UK has allowed significant increases in the number of children with end-stage heart failure who can be successfully bridged to transplant and the length of time they can be supported. The total number of transplants has not increased.

Diagnosis of hemolysis and device thrombosis with lactate dehydrogenase during left ventricular assist device support
Mechanical circulatory support (MCS) with a continuous-flow (CF) rotary pump is associated with low levels of hemolysis during normal pump operation. Clinically significant hemolysis can be an early sequelae of pump thrombus. Left ventricular assist device (LVAD) thrombosis may result in stroke, peripheral embolism, heart failure, device exchange, and death. The timely detection of pump thrombus remains challenging.

Incidence of increases in pump power use and associated clinical outcomes with an axial continuous-flow ventricular assist device
Left ventricular assist devices (LVADs) have been shown to improve survival in patients with end-stage heart failure. Newer-generation LVADs with continuous-flow mechanics yield lower rates of disabling stroke, infection, and need for device exchange compared with earlier pulsatile-flow devices. It has been hypothesized that an elevation in the pump power may be an early indication of device thrombosis. Our goal was to define the frequency of pump power elevations, evaluate when they happen in relation to device implantation, and determine the rate at which they precede adverse events suggestive of pump thrombosis.

Post-approval study of a highly pulsed, low-shear-rate, continuous-flow, left ventricular assist device, EVAHEART: A Japanese multicenter study using J-MACS
Conclusions: The EVAHEART device provides safe, reliable and long-term circulatory support with improved survival in commercial settings of BTT in Japan, where the transplant waiting period is much longer. Incidences of GI bleeding, hemolysis, right ventricular failure, device thrombosis and mechanical failure were extremely rare in patients on EVAHEART devices.

First Implantation in Man of a New Magnetically Levitated Left Ventricular Assist Device (HeartMate III)
Outcomes of heart failure patients supported by a continuous flow left ventricular assist device (LVAD) have steadily improved over the past decade due in large part to better patient selection and management 1,2. Nevertheless, adverse events such as bleeding, infection, stroke and thrombus persist and limit the overall effectiveness of this therapy. Bleeding is the most common serious adverse event that results from the extensive surgery required for implantation and blood component damage due to shear forces in the small blood flow paths of current design axial-flow and centrifugal-flow pumps.
