Ischemic Stroke and Intracranial Hemorrhages During Impella Cardiac Support
Impella is a percutaneously placed, ventricular assist device for short-term cardiac support. We aimed to study acute neurologic complications during short-term cardiac support with Impella. We reviewed prospectively collected data of 79 consecutive persons implanted with Impella at a single tertiary center. Acute neurologic events (ANE) were defined as ischemic strokes or intracranial hemorrhages. Among those with ANE, specific causes of ischemic and hemorrhagic events were collected and discussed. Of 79 persons with Impella with median 8 days of support (range 1–33 days), six (7.5%) developed ANE at a median of 5 days ...

Computed tomography perfusion in patients of stroke with left ventricular assist device
AbstractLeft ventricular assist devices (LVAD) are widely applied for patients with severe heart failure as a bridge to heart transplantation as well as destination therapy. Patients with implanted LVAD have an increased risk of cerebral thrombosis and computed tomographic perfusion (CTP) has the potential to be performed for early diagnosis and treatment of acute ischemic stroke (AIS), including interventional thrombectomy. Here, we report our series of CTP examination in patients having suspected AIS after LVAD implantation. We retrospectively investigated 33 contrast-enhanced CTPs from January 2017 to December 2018 whic...

Hyperhomocysteinemia and Oxidative Stress May Predict the Risk of Stroke in Patients Supported by Continuous Flow Left Ventricular Assist Devices
Stroke is one of the leading complications during CF-LVAD support. The purpose of this observational study was to investigate the temporal relationship of circulating homocysteine (Hcy) and oxidative stress as potential markers to identify CF-LVAD patients at risk for developing postoperative strokes.

Low Left Ventricular Stroke Work Index is Associated with a Poor Prognosis in LVAD Patients
Hemocompatibility-related adverse events (HRAE) are thought to be largely driven by the pump-patient interaction. We hypothesized that patients with left ventricular assist devices (LVADs) with low left ventricular stroke work index (LVSWI), and thus less native contribution to total flow, would have more adverse clinical outcomes.

Prognostic Importance of Pulmonary Artery Pulsatility Index and Right Ventricular Stroke Work Index in End-Stage Heart Failure Patients
Conclusion: The low PAPi was an ind ependent risk for ACE and it had a linear association with it. However, RVSWI seems to be have a nonlinear association with ACE (J-curve pattern).

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 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.

Incidence and Impact of Post-Transplant Stroke on Outcomes Following Orthotopic Heart Transplantation Under the 2018 United States Heart Allocation System: A UNOS Registry Analysis
With the increased rate of temporary mechanical circulatory support utilization after the 2018 heart allocation policy change, we sought to quantitate the clinical trends and impact of post-transplant stroke (PTS) and functional independence on outcomes following orthotopic heart transplant (OHT).

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.

Dh-452784-2 identifying atrial fibrillation with sinus rhythm electrocardiogram using artificial intelligence in embolic stroke with undetermined source
Previous studies have demonstrated acceptable ranges of accuracy of artificial intelligence (AI) algorithms for identifying patients with paroxysmal atrial fibrillation (AF) based on their sinus rhythm electrocardiograms (ECGs). However, none of them has been validated in patients with embolic stroke with undetermined source (ESUS) in which thorough AF screening is required.

Preoperative higher right ventricular stroke work index increases the risk of de novo aortic insufficiency after continuous-flow left ventricular assist device implantation
This study investigated the influence of preoperative hemodynamic parameters on de novo AI in CF-LVAD recipients. We reviewed 125 patients who underwent CF-LVAD implantation without concomitant AV surgery between 2005 and 2018. De novo AI was defined as moderate or severe AI in those with none or trivial preoperative AI. During mean 30 ± 16 months of CF-LVAD support, de novo AI-free rate was 86% and 67% at 1 and 2 years, respectively. Multivariable analysis showed that higher right ventricular stroke work index (RVSWI) (hazard ratio, 1.12 /g/m2/beat; 95% confidence interval, 1.00 –1.20;p = 0.047) and trivial ...
