Multidisciplinary Approach to Patent Foramen Ovale Closure for Cryptogenic Stroke: Brain-Heart Board Experience.

Background And Objectives: Patent foramen ovale (PFO) is present in approximately 25% of adult population. The prevalence of PFO is high in patients with cryptogenic stroke suggesting paradoxical embolism. PFO closure in carefully selected patients is an effective secondary preventive strategy in these patients.

Neurogenic cardiac outcome in patients after acute ischemic stroke: The brain and heart connection.

Background: Neurogenic cardiac impairment can occur after acute ischemic stroke (AIS), but the mapping of the neuroanatomic correlation of stroke-related myocardial injury remains uncertain. This study aims to identify the association between cardiac outcomes and middle cerebral artery (MCA) ischemic stroke, with or without insular cortex involvement, as well as the impact of new-onset atrial fibrillation (AF) after AIS on recurrent stroke.

Methods: Serial measurements of high sensitivity troponin T (TnT), brain natriuretic peptide (BNP), electrocardiography (ECG), echocardiogram, and cardiac monitoring were performed on 415 patients with imaging confirmed MCA stroke, with or without insular involvement.

Shorter Intensive Care Unit Stay (12 Hours) Post Thrombolysis Is Safe and Reduces Length of Stay for Minor Stroke Patients.

The current standard of practice for patients with acute ischemic stroke treated with intravenous tissue-type plasminogen activator (tPA) requires critical monitoring for 24-hours post-treatment due to the risk of symptomatic intracranial hemorrhage (sICH). This is a costly and resource intensive practice. In this study, we evaluated the safety and efficacy of this standard 24-hour ICU monitoring period compared with a shorter 12-hour ICU monitoring period for minor stroke patients (NIHSS 0-5) treated with tPA only.

Jamestown Canyon Virus (JCV) Encephalitis Mimicking Acute Stroke in Michigan: A Case Report and Review of the Literature.

Jamestown canyon virus (JCV) is an arbovirus and is an under-recognized cause of mosquito-borne viral encephalitis. In this report we present a patient who presented with focal neurological deficits. Patient was initially evaluated for stroke.

Impact of a Stay-at-Home Order on Stroke Admission, Subtype, and Metrics during the COVID-19 Pandemic.

Objective: Our study aims to evaluate the impact of a stay-at-home order on stroke metrics during the 2019-novel coronavirus (COVID-19) pandemic.

Methods: Data on baseline characteristics, stroke subtype, initial National Institutes of Health Stroke Scale (NIHSS) score, the time between last known well (LKW) to emergency department (ED) arrival, tissue plasminogen activator (tPA) administration, the involvement of large vessel occlusion (LVO), and whether mechanical thrombectomy (MT) was pursued in patients with acute stroke were extracted from 24 March to 23 April 2020 (the time period of a stay-at-home order was placed due to the COVID-19 pandemic as the study group) at a tertiary care hospital in West Michigan, USA, compared with data from 24 March to 23 April 2019 (control group).

Results: Our study demonstrated a reduction in cases of acute ischemic stroke (AIS), although this did not reach statistical significance.

Mechanical Thrombectomy for Acute Stroke: Early versus Late Time Window Outcomes.

Background And Purpose: Recent trials have shown benefit of thrombectomy in patients selected by penumbral imaging in the late (>6 hours) window. However, the role penumbral imaging is not clear in the early (0-6 hours) window. We sought to evaluate if time to treatment modifies the effect of endovascular reperfusion in stroke patients with evidence of salvageable tissue on CT perfusion (CTP).

The Role of CT Perfusion in Defining the Clinically Relevant Core Infarction to Guide Thrombectomy Selection in Patients with Acute Stroke.

Background And Purpose: Infarct core assessment on presentation is important to evaluate salvageable tissue to select patients for thrombectomy. Our study aims to evaluate the correlation between infarct core volume measured by computed tomography (CT) perfusion (CTP) and magnetic resonance diffusion-weighted imaging (MR-DWI) in patients with acute large-vessel occlusion.

Methods: We studied patients who underwent CTP on presentation to the emergency department for stroke symptoms.
