The gap between indicated and prescribed stroke prevention therapies in a high-risk geriatric population
ConclusionsThis data set suggests that 37% of eligible elderly LTC residents failed to receive recommended stroke prevention therapies.

Transoesophageal echocardiography prior to catheter ablation could be avoided in atrial fibrillation patients with a low risk of stroke and without filling defects in the late-phase MDCT scan: A retrospective analysis of 783 patients
ConclusionsFor AF patients with low risk of stroke, when MDCT images showed no filling defect in the late phase, TEE prior to catheter ablation can be avoided.Key Points•MDCT can help detect the presence of LAA thrombus.•TEE can be avoided when late-phase MDCT shows no filling defect.•TEE is required in patients whose MDCT images indicate thrombus.

A Non-linear Association Between Total Small Vessel Disease Score and Hemorrhagic Transformation After Ischemic Stroke With Atrial Fibrillation and/or Rheumatic Heart Disease
Background: Previous studies have investigated the association between a single marker of cerebral small vessel disease (SVD) and hemorrhagic transformation (HT). However, the effect of the total SVD burden on HT has not been evaluated yet. We aimed to investigate the association between the total SVD score and HT in ischemic stroke patients with atrial fibrillation (AF) and/or rheumatic heart disease (RHD). Methods: Ischemic stroke patients with AF and/or RHD admitted within 7 days after onset were enrolled at two hospitals in China. The total SVD score was based on the presence of lacunes, extensive white matter hyperin...

Screening of Embolic Sources by Point-of-Care Ultrasound in the Acute Phase of Ischemic Stroke
Our objective was to evaluate hand-held echocardiography as point of care ultrasound scanning (POCUS) to detect sources of embolism in the acute phase of stroke. Prospective, unicentric observational cohort study of non-lacunar ischemic stroke patients evaluated by V Scan device. The main sources of embolism (MSEs) were classified into embolic valvulopathies and severe ventricular dysfunction. We looked for atrial fibrillation (AF) predictors in strokes of undetermined etiology. MSEs were detected in 19.23% (25/130).

Mesial bifrontal stroke presenting as isolated spontaneous confabulations.
Abstract A 52-year-old man with paroxysmal atrial fibrillation presented with spontaneous confabulation, working memory deficits, and frontal release signs. MR scan of brain showed bifrontal mesial ischaemic strokes and angiography demonstrated that both anterior cerebral arteries were supplied by the left internal carotid artery. Isolated spontaneous confabulation is a rare presentation of stroke and may be associated with orbitofrontal cortex lesions. Interestingly, functional imaging during rapid-eye-movement sleep may show bilateral medial frontal lobe hypometabolism, suggesting anatomical overlap between drea...

Systematic Screening for Atrial Fibrillation in Patients at Moderate-to-High Risk of Stroke 　- Potential to Increase the Atrial Fibrillation Detection Rate (SCAN-AF)
CONCLUSIONS: Sequential use of a BP monitor and handheld ECG for 4 weeks is a practical strategy for identifying undiagnosed AF in Japanese people at heightened risk of stroke.PMID:35125371 | DOI:10.1253/circj.CJ-21-0813

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...

Impact of frailty models on the prescription of oral anticoagulants and on the incidence of stroke, bleeding, and mortality in older patients with atrial fibrillation: a systematic review
CONCLUSIONS: Due to the great heterogeneity among different validated frailty measures, indiscriminately relying on "frailty" should not be regarded as the gold standard for clinical decision-making about stroke prevention in older AF patients. Present findings suggest that severe frailty according to the DAM is associated with less use of OAT and increased risk of all-cause mortality, thereby representing at the moment the most reasonable tool to efficiently recognize patients with limited life expectancy and for whom there is so far scant, if any, evidence of a clinical benefit of OAT.AVAILABILITY OF DATA AND MATERIAL: A...

Usefulness of the MrWALLETS Scoring System to Predict First Diagnosed Atrial Fibrillation in Ischemic Stroke Patients
In this study we searched for echocardiographic parameters associated with first diagnosed AF, to form a scoring system for the identification of AF patients. We examined 571 ischemic stroke patients (72.7 ±13.5 years, 50.6% women), subdivided into 4 groups: documented cause without AF, first diagnosed AF, known paroxysmal AF, and permanent AF. All patients underwent transthoracic echocardiography, brain CT scan, carotid/vertebral ultrasound, and continuous ECG monitoring.

Po-697-02 impact of left atrial appendage stump on arrhythmogenicity and stroke risk after atri-clip in patients with persistent atrial fibrillation
Surgical left atrial appendage occlusion (LAAO) with an atrial clip (Atricure) is frequently performed for stroke prophylaxis in patients with atrial fibrillation (AF). Scant data exist for arrhythmogenicity and thromboembolic risk with the residual LAA stump.

Case of malignant brain edema despite successful recanalization after mechanical thrombectomy for anterior circulation stroke
CONCLUSION: MBE after MT results in unsatisfactory functional outcomes, even if it has successful revascularization. No collateral in the territory of the occluded vessel in the initial angiogram is one of the predictors of MBE after MT.PMID:37151444 | PMC:PMC10159319 | DOI:10.25259/SNI_28_2023
