Differential Diagnosis of New Giant T-Wave Inversions
To the Editor The electrocardiogram (ECG) presented by Dr Cai and colleagues is indeed a great challenge. Two days after a fall, an older patient was admitted to the hospital with a hip fracture that was treated by external fixation and skin traction. On hospital day 2, the patient suddenly lost consciousness. An ECG immediately performed showed giant negative T waves (>20 mm) in the precordial leads and a QTc prolongation of 535 milliseconds. Cardiac troponin was elevated. Findings of computed tomography and magnetic resonance imaging (performed because of neurologic deficits) showed bilateral multifocal subacute ische...

Improving door-to-reperfusion time in acute ischemic stroke during the COVID-19 pandemic: experience from a public comprehensive stroke center in Brazil
ConclusionAcute stroke care continued to be a priority despite the COVID-19 pandemic. The implementation of a thrombolytic bolus and the start of continuous infusion on the CT scan table was the main factor that contributed to the reduction of DNT. Continuous monitoring of service times is essential for improving the quality of the stroke center and achieving better functional outcomes for patients.

Improved language function for post-stroke aphasia in the long term following repeated repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy: a case report
ConclusionsThe findings of the study indicate that the repeated use of repetitive transcranial magnetic stimulation and intensive speech-language-hearing therapy may be effective in improving and preserving language function and increasing cerebral blood flow for aphasia following stroke.

TCCD Fusion Imaging to Estimate Intracranial Pressure and Tissue Displacement with Large Hemispheric Infarction
ConclusionsFusion imaging is an easy method to access and acquire measurements for critical care patients and follow-up of tissue and vascular displacement after stroke. Fusion imaging may be a decisive support for indicating hemicraniectomy.

Evaluating cardiac function with chest computed tomography in acute ischemic stroke: feasibility and correlation with short-term outcome
ConclusionHydrostatic lung changes on chest CT can be used as an indicator of cardiac function and as a preliminary reference for short-term outcome in AIS patients.

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...

Contribution Of Mitral Valve Atrioventricular Plane Displacement To The Stroke Volume In Patients With Severe Mitral Regurgitation
Introduction: Longitudinal shortening measured as atrioventricular plane displacement (AVPD) represents a piston-like movement of the base of the ventricles toward the apex during the cardiac cycle. Prior studies using echocardiography and cardiac magnetic resonance imaging demonstrated AVPD to account for a large part of the left ventricular (LV) stroke volume (SV) in athletes, healthy controls, and heart failure patients. We sought to validate the use of cardiac computed tomography (CCT) to measure the AVPD and subsequently explore the contribution of the AVPD towards overall LV SV in patients with functional and primary...

Relationship Between Thoracic Aortic Calcification And Coronary Artery Calcium Measured On Chest CT Scans
Introduction: Cerebrovascular accidents (CVA) remain a leading cause of mortality and morbidity worldwide. Identifying appropriate risk markers may allow detection of patients at high risk for stroke who would benefit from early initiation of preventative measures. Utilizing atherosclerotic burden of multiple vascular beds may allow for improved cardiovascular risk assessment. Coronary artery calcium (CAC) is a well-established, excellent predictor of coronary heart disease, but its association with stroke is modest.

Streamlined Carotid Artery Calcification Labeling For Cta Scans
Introduction: We require vast amounts of manually labeled calcifications to train advanced machine learning classifiers for carotid artery plaque detection and phenotyping high-risk calcifications for ischemic stroke patients. We developed CTOOL, a web-based software for streamlined calcium labeling with minimal user interaction.

Clinical Significance and Influencing Factors of Microvascular Tissue Reperfusion After Macrovascular Recanalization
In this study, we aimed to investigate the impact of tissue optimal reperfusion (TOR) and its influencing factors. From December 1, 2020 to December 1, 2021, AIS patients with successful recanalization (modified Thrombolysis in Cerebral Infarction score [mTICI] ≥ 2b) after mechanical thrombectomy (MT) were retrospectively reviewed. Computed tomography perfusion was performed before and after MT. Successful reperfusion was assessed by TOR, defined as > 90% reduction of the Tmax > 6 s lesion volumes between baseline and early follow-up perfusion profiles. The impact of TOR on functional outcomes after...

Investigation of Mechanical Thrombectomy in Elderly Patients over 85 Years Old: A Multicenter Study
This study examined the usefulness of thrombectomy in the elderly. We retrospectively analyzed patient data using a multicenter acute ischemic stroke registry (NGT-FAST). We examined outcomes in patients 75 years and older who underwent thrombectomies between January 1, 2021, and December 31, 2021. The patients were divided into two groups: the 75-84-year-old group and the 85+-year-old group. There was no difference in the pretreatment National Institutes of Health Stroke Scale score or Alberta Stroke Program Early Computed Tomography Score between the two groups, but the 85+-year-old group had a significantly lower rate o...
