Detection of inflow obstruction in left ventricular assist devices by accelerometer: A porcine model study
Left ventricular assist devices (LVAD) provide circulatory blood pump support for severe heart failure patients. Pump inflow obstructions may lead to stroke and pump malfunction. We aimed to verify in vivo that gradual inflow obstructions, representing prepump thrombosis, are detectable by a pump-attached accelerometer, where the routine use of pump power (PLVAD) is deficient.

Platelet Function and Sildenafil Use During Left Ventricular Assist Device Support
Clinical outcome studies have shown that sildenafil is associated with reduced mortality and thrombotic events such as ischemic stroke during contemporary left ventricular assist device (LVAD) support. Sildenafil has anti-platelet properties but its relation to platelet function during LVAD support is uncertain.

A Retrospective Study on Gender, LAA Morphology and Stroke Risk
This was a retrospective study to investigate whether gender and LAA size/morphology was a predictor of cerebral vascular events in patients undergoing cardiac surgery. We studied the LAA morphology, and measurements for women and men in an attempt to correlate the different morphologies/sizes with the patient's risk of stroke.

Comparing Velocity and Mean Arterial Pressure to Assess Pulsatility in Patients with Continuous Flow Left Ventricular Assist Devices
An increasing number of end-stage heart failure patients are supported by continuous-flow Left Ventricular Assist Devices (cfLVADs). In these patients, accurate assessment of arterial pulsatility remains a challenge because of diminished pulse pressure. Limited pulsatility in modern cfLVADs itself can be associated with adverse events such as stroke. Our study investigates the value of simultaneous arterial pressure and arterial blood velocity assessment in cfLVAD patients.

Optimization of Left Ventricle Size After VAD Implantation Prevents Incidence of Cerebral Infarction
Stroke after ventricular assist device (VAD) implantation is a critical complication. Previous studies have noted the distance between the inflow cannula and the left ventricular (LV) septum, as well as an angulation of the inflow cannula from the apical axis, related to the incidence of stroke. In the early phase after VAD implantation, diuresis is caused by improved renal blood flow, furthermore, rapid volume reduction of LV greatly changes circulating plasma volume, resulting in increased stroke risk; however, little is known about an appropriate indicator for the prevention of this phenomenon.

Who is at Risk for Seizures After Heart Transplantation?
Seizures may occur following heart transplantation (HTx), especially since tacrolimus can lower a seizure threshold. HTx recipients are also at high stroke risk given many patients have existing cerebrovascular disease. The purpose of the study was to assess the prevalence and risk factors for seizures in HTx recipients at our center.

Assessing Cardiac Recovery for Decommissioning of LVAD Support: Structure versus Function
Recovery of left ventricular (LV) function during LVAD support occurs in only 1-3% of patients. Assessment for recovery and LVAD removal is desirable given the risks of infection, stroke, and device malfunction. This case of a patient with an LVAD, with recovered LV systolic function but abnormal exercise hemodynamics, illustrates the potential utility of right heart catheterization studies for clinical decisions.
