Rescue intracranial stenting in acute ischemic stroke (study)
CONCLUSION: Our study suggests that despite the occurrence of postprocedural symptomatic intracerebral hemorrhage in a low proportion of cases, rescue intracranial stenting could be an important alternative treatment after mechanical thrombectomy failure.PMID:37415427 | DOI:10.1177/15910199231171272

Benchtop evaluation of a double stent retriever thrombectomy technique for acute ischemic stroke treatment
CONCLUSIONS: In vitro evaluation of the mechanism of action of the double stent retriever provided explanations that appear to support the high efficacy of such an approach in patient cohorts and could help operators when selecting the optimal mechanical thrombectomy strategy in cases of arterial occlusions difficult to treat with a single stent retriever.PMID:37415424 | DOI:10.1177/15910199231179846

Multicenter comparison of antiplatelet treatment strategies for urgent/emergent neuroendovascular stenting
CONCLUSION: The optimal timing of antiplatelet administration in relation to stent placement and route of administration of antiplatelet agents is unclear. Timing and route of administration of antiplatelet agents may have an effect on thrombosis in emergent neuroendovascular stenting. Significant practice variation exists in antiplatelet agent utilization in emergent neuroendovascular stenting.PMID:37402388 | DOI:10.1177/15910199231180003

Systematic Review and Meta-analysis of Radial or Femoral Access for Carotid Stenting
ConclusionThe modest quality of the data suggested comparable procedural outcomes between the transradial and transfemoral approaches when performing carotid stenting; however, high level evidence regarding postoperative brain images and risk of stroke in transradial carotid stenting are lacking. Therefore, it is reasonable for interventionists to weigh up the risks of neurological events and potential benefits, including fewer access site complications, before choosing the radial or femoral arteries as access sites. Future large-scale randomized controlled trials are imperative.

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.

Hemodynamic outcomes of stenting for vertebrobasilar insufficiency in patients with a low flow state
