Antiphospholipid Syndrome Diagnosed as a Result of the Occurrence of an Ischemic Stroke After a Successful Catheter Ablation of Atrial Fibrillation and Continuous Direct Oral Anticoagulants
We report a case of an ischemic stroke after a successful catheter ablation of atrial fibrillation (AF) and continuous oral anticoagulation therapy with direct oral anticoagulants (DOACs), which was the trigger for diagnosing antiphospholipid syndrome (APS). A 68-year-old woman underwent catheter ablation of persistent AF and continued oral anticoagulation with edoxaban at a dose of 30 mg once daily after the ablation procedure. An asymptomatic intracerebral hemorrhage was detected by brain computed tomography and magnetic resonance imaging one month post-ablation. Oral anticoagulation with dabigatran at 110 mg twice daily...

Predictors and Outcomes of Salvaging the Corticospinal Tract After Thrombectomy in Basilar Artery Occlusion Stroke
ConclusionCST salvage was associated with good functional outcomes in patients with BAO treated with thrombectomy. The presence of atrial fibrillation, location and length of BAO may predict CST salvage after thrombectomy, and rapid treatment with thrombectomy may protect this eloquent tract in these patients.

Embolic infarct topology differs between atrial fibrillation subtypes and embolic stroke of undetermined source
CONCLUSION: Cortical infarctions were twice as common among patients with AF versus ESUS. Subcortical infarct topography was strongly associated with chronic microvascular ischemic changes and therefore may not represent embolic phenomena. Larger-scale investigations are warranted to discern whether large or multifocal subcortical infarcts ought to be excluded from the ESUS designation.PMID:36130470 | DOI:10.1016/j.jstrokecerebrovasdis.2022.106782

Rational clinical approach to transient ischaemic attack, stroke and associated mimics: A retrospective cohort study
CONCLUSIONS: The present study demonstrated that specific clinical features and risk factors were associated with the final diagnosis at TIA clinic. These clinical features may assist with diagnosis of TIA in centres without access to a vascular neurologist.PMID:37190670 | DOI:10.1111/1742-6723.14238

Improved cerebral blood flow and hippocampal blood flow in stroke ‐free patients after catheter ablation of atrial fibrillation
ConclusionSR restoration with catheter ablation was associated with improved CBF and HBF at 3 months, maintenance of blood flow, and improved cognitive function at 12 months.

Simultaneous onset of myocardial infarction and ischemic stroke in a patient with atrial fibrillation: Multiple territory injury revealed on angiography and magnetic resonance
An 84-year-old man with a history of hypertension and paroxysmal atrial fibrillation (AF) who received no anticoagulant drugs experienced acute chest pain and transient loss of consciousness. He was transferred to our emergency room. His initial electrocardiogram showed sinus rhythm with ST-segment elevation in the I, aVL, and V1–V6 leads. His blood pressure was 158/92mmHg and his pulse was regular at 70beats per minute. A chest radiograph showed increased heart size and pulmonary vascular congestion. His troponin T level was elevated (more than 0.1ng/mL). He was diagnosed with ST-elevation myocardial infarction (MI) and...

Early Administration of Non-Vitamin K Antagonist Oral Anticoagulants for Acute Ischemic Stroke Patients With Atrial Fibrillation in Comparison With Warfarin Mostly Combined With Heparin.
Conclusions:This study suggests that NOACs are suitable for AIS patients with Af, perhaps even better than warfarin, given their simplicity. PMID: 25736910 [PubMed - as supplied by publisher]

Association between leukoaraiosis and hemorrhagic transformation after cardioembolic stroke due to atrial fibrillation and/or rheumatic heart disease
Cardioembolic stroke due to atrial fibrillation (AF) and/or rheumatic heart disease (RHD) often involves hemorrhagic transformation (HT), and we examined whether leukoaraiosis (LA) was associated with HT in these cases. We prospectively enrolled 251 patients who were admitted to two hospitals within one month of experiencing cardioembolic stroke due to AF/RHD. LA severity was assessed using three visual rating scales. HT was identified in 99 patients (39.4%) based on baseline computed tomography (CT) and post-admission magnetic resonance imaging or second CT.

Increased Blood Residence Time as Markers of High-Risk Patent Foramen Ovale
AbstractPrevious investigations have suggested that patients with patent foramen ovale (PFO) often have an atrial dysfunction, like to that observed in patients with atrial fibrillation (AF) which may concur to an increased risk of cryptogenic stroke. The aim of the study is to compare the atrial resident time (Rt) of PFO patients to those with sinus rhythm (SR) and AF using patient-specific 3D computational fluid dynamics (CFD) analysis. Models of left atrium (LA) hemodynamics were obtained from time-resolved CT scans and transthoracic echocardiography (TTE). Enrolled patients were divided into three groups: 30 healthy su...
