Quiz case: a clinical reasoning challenge in the emergency stroke setting
AbstractA right-handed woman in her 80s was admitted to the emergency department 1 h after sudden-onset global aphasia and right-sided hemiparesis. Medical history included arterial hypertension, dyslipidemia, hyperuricemia, aortic stenosis, osteoporosis, and recent pulmonary embolism. Medication consisted of apixaban, bisoprolol, hydrochlorothiazide, allopurinol, fenofibrate, and vitamin D. Vital parameters (blood pressure, heart rate, body temperature, oxygen saturation) and glycemia were all within normal range. Electrocardiogram showed a first-degree atrioventricular block. The patient was promptly transported to the e...

Predictive Ability Of More Than 3-day Pre-atrial Fibrillation Ablation Cardiac Computed Tomography In Detection Of Left Atrial Thrombus
Introduction: Several studies described the diagnostic accuracy of Cardiac Computed Tomography (CCT) with delayed phase in detection of LA/LAA thrombus. Pre-Atrial fibrillation ablation (AFA) CCT is primarily done for pulmonary vein mapping. CCT performed alone within 72 hours prior to AFA has been suggested to be an alternative to Transesophageal Echocardiography (TEE) to rule out LAA thrombus in the low-intermediate stroke risk patients.(1) Hounsfield Unit ratio (HU) of> 0.75 between left atrial appendage (LAA) and ascending aorta (AA) has been suggested as reliable indicator of absence of thrombus on CCT(2) However, pre...

Mechanical thrombectomy for acute paradoxical cerebral embolism due to pulmonary arteriovenous malformation: A case report and review of literature
CONCLUSION: Although rare, PAVM is a treatable cause of stroke in relatively young adults; thus, it is important to keep in mind the possibility of its presence.PMID:36751447 | PMC:PMC9899467 | DOI:10.25259/SNI_987_2022

SARS-CoV-2 infection and SLE: endothelial dysfunction, atherosclerosis, and thrombosis
We present systemic lupus erythematosus (SLE) as a model rheumatic disease with endothelial dysfunction and discuss its mechanisms, factors that influence the early onset and rapid progression of atherosclerosis, and the increased risk of thromboembolic events. We focus on established methods to improve endothelium function, including statins, antiplatelet, and antithrombotic therapy. Hypercoagulable and hypofibrinolitic states and a hyperinflammatory response characterize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Several pathogenic mechanisms are typical for an acute phase of Covid-19 post-Co...

Clinical characteristics, multiorgan dysfunction and outcomes of patients with COVID-19: a prospective case series
This study provides further evidence that COVID-19 is a multisystem disease involving neurologic, cardiac and thrombotic dysfunction, without evidence of hepatic dysfunction. Patients have persistent organ dysfunction after hospital discharge, underscoring the need for research on long-term outcomes of COVID-19 survivors.PMID:35853662 | DOI:10.9778/cmajo.20210151

Ventricular-arterial decoupling is associated with in-hospital adverse events in normotensive pulmonary embolism
AbstractDuring acute pulmonary embolism (PE) a compensatory increase in right ventricular (RV) contractility is required to match increased afterload to maintain right ventricular-pulmonary arterial (RV-PA) coupling. The aim of this study was to assess the prognostic utility of RV-PA decoupling in acute PE. We assessed the association between measures of transthoracic echocardiography (TTE)-derived RV-PA coupling including tricuspid annular plane systolic excursion (TAPSE)/right ventricular systolic pressure (RVSP) and right ventricular fractional area change (FAC)/RVSP as well as stroke volume index (SVI)/RVSP (a measure ...

On the Impact of Left Upper Lobectomy on the Left Atrial Hemodynamics
The left atrium (LA) functions to transport oxygenated blood from the pulmonary veins (PVs) to the left ventricle (LV). LA hemodynamics has received much attention because thrombosis in the LA in pathological states, such as atrial fibrillation, is a major factor leading to thromboembolic stroke. In the last 5 years, multiple cohort studies have revealed that left upper lobectomy (LUL) with PV resection risks thrombus formation in the PV stump even in the normal LA without a history of cardiac disease; the causal mechanism is, however, an open question. The present study investigated the potential effect of an LUL on LA he...

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.
