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.

Prognostic Value of Pressure-Volume Measures in Hemocompatibility-Related Clinical Adverse Events
Continuous-flow left ventricular assist device (cf-LVADs) can lead to hemocompatibility-related clinical adverse events (HRAEs) which are largely determined by mechanisms that underpin the pump-patient interaction. We assessed the association of pressure-volume (PV) measures [stroke work (SW)& pump arterial elastance (EA)] with incidence of HRAEs.

Postoperative Atrial Fibrillation in Lung Transplant Recipients with and without Concomitant Modified Maze
Atrial fibrillation is common following lung transplantation and may contribute to increased risk of stroke. The goal of this study was to characterize the incidence of atrial fibrillation in lung transplant recipients with and without a concomitant modified Maze procedure.

A Prospective Randomized Trial Comparing Stroke Volume Measurements by Esophageal Doppler and Pulse-Contour Analysis During a Fluid Resuscitation Protocol in Brain-Dead Organ Donors
Maximizing stroke volume (SV) is the optimal method of fluid resuscitation. Both the esophageal doppler (EDM) and pulse contour analysis (PCA) are validated methods of measuring SV in critical patients, but neither have not been well-studied in the brain-dead (BD) donor. We have previously published our fluid resuscitation protocol in BD donors demonstrating a significant reduction in time on vasopressors from 16 hours in the control group to 2.9 hours in the protocol group. We performed a prospective randomized trial comparing the effectiveness of the EDM and PCA in this fluid resuscitation protocol in BD donors.

Stroke Risk in the Contemporary Era of Left Ventricular Assist Device Support
The HeartMate 3 left ventricular assist device (LVAD) has lower stroke rates compared to the HeartMate 2 in a clinical trial setting. Here we report real world stroke rates in patients implanted with HeartMate 2 and HeartMate 3 LVADs.

Sex-Based Differences in Clinical Outcomes of Stroke Related to LVAD
Sex-based differences among patients with left ventricular assist devices (LVAD) having stroke are uncertain. We aimed to compare demographic and clinical characteristics, inpatient outcomes, and measures of health care utilization among men and women who had stroke while undergoing LVAD implantation.

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.

Association of Outflow Cannula Angulation with Adverse Neurological Events in Patients with CF-LVAD
Adverse neurological outcomes are the Achilles heel of the current day LVAD technology and are associated with worse survival. Our previous data suggests that outflow cannula (OFC) angles measured using cardiac CT may correlate with stroke in continuous-flow HeartMate II patients. Therefore, the aim of our study was to assess the relationship of inflow cannula (IFC) and outflow cannula (OFC) position with neurological outcomes centrifugal flow pumps (HM3 and HVAD).

Bacteriophage Therapy and the Biofilm: An Old Solution for a Persistent and Desperate Problem?
With the adoption of use of continuous-flow pumps with centrifugal design and complete magnetic levitation (i.e., HeartMate 3, Abbott, Chicago, IL), outcomes following durable left ventricular assist device (LVAD) have continuously improved over the last five years (1). Improved hemocompatibility associated with this device design has translated into a significant reduction in major adverse events, primarily pump thrombosis, stroke, and to a lesser extent, reduction in non-surgical bleeding (1).
