Association between Fibrinogen and Leukoaraiosis in Patients with Ischemic Stroke and Atrial Fibrillation
Leukoaraiosis (LA), a surrogate of cerebral small-vessel diseases (CSVD), has been increasingly recognized because of its high prevalence and strong prognostic value in stroke. But the mechanism of LA is incompletely clarified. Fibrinogen is a crucial role in coagulation cascade and inflammation. There are inconsistent reports on the association of fibrinogen with LA in the general population. We aimed to investigate the association between fibrinogen and LA in patients with stroke and atrial fibrillation (AF), which was not ever reported before.

Anticoagulant-Free but Dangerous: Perisurgical Consideration
It is recognized that anticoagulants should be withdrawn before surgery or invasive tests for the recommended period. However, it is not well known when anticoagulants should restart. For the past 12 months, we had 5 patients who suddenly developed ischemic stroke after a prolonged withdrawal of anticoagulants for atrial fibrillation.

Repeated Mechanical Thrombectomy in the Same Intracranial Artery Segment
We report a patient with an important scenario that may arise in the management of an acute ischemic stroke: the need for a repeated mechanical thrombectomy in the same intracranial artery segment. The patient had a history of atrial fibrillation and a mechanical mitral valve replacement. In her first stroke, she had an occlusion of the proximal segment of the right middle cerebral artery; 58 days later, she presented with an occlusion in the same segment of that cerebral artery. In both instances, the thrombus was extracted by a stent retriever with good clinical and radiographic results.

Severe Vasospasm of the Middle Cerebral Artery after Mechanical Thrombectomy Due to Infective Endocarditis: An Autopsy Case
We describe a case of middle cerebral artery occlusion due to IE, which caused severe vasospasm and reocclusion after mechanical thrombectomy (MT). We present the pathologic findings of the occluded middle cerebral artery and investigate the precautions to be taken while performing MT due to IE. A 72-year-old man with atrial fibrillation treated with dabigatran presented with right hemiparesis and aphasia.

Suboptimal Anticoagulant Management in Japanese Patients with Nonvalvular Atrial Fibrillation Receiving Warfarin for Stroke Prevention
Atrial fibrillation (AF) is the most common cardiac arrhythmia, with increasing prevalence in Japan. Although prothrombin time –international normalized ratio (PT-INR) targets for monitoring warfarin therapy in patients with nonvalvular AF (NVAF) are well defined, real-world patient characteristics and PT-INR levels remain unknown among Japanese patients with NVAF who initiate and continue warfarin (warfarin maintainers) versus those who switch from warfarin to direct oral anticoagulants (DOACs; warfarin switchers).

Acute Stroke Despite Dabigatran Anticoagulation Treated with Idarucizumab and Intravenous Tissue Plasminogen Activator
Dabigatran is a direct thrombin inhibitor used to reduce the risk of stroke in patients with nonvalvular atrial fibrillation. For patients who present with an acute stroke despite dabigatran therapy, clinical data on the use of intravenous tissue plasminogen activator (IV-tPA) is limited. There is an anticipated increased risk of symptomatic intracranial hemorrhage (sICH) when using IV-tPA in patients on dabigatran therapy. In 2015, the humanized monoclonal antibody fragment idarucizumab was approved for rapid (minutes) reversal of anticoagulant effects of dabigatran.

Genetic and Non-Genetic Factors Affecting the Quality of Anticoagulation Control and Vascular Events in Atrial Fibrillation
Warfarin has a narrow therapeutic window. We hypothesized that genetic factors related to warfarin metabolism (CYP2C9) and activity (VKORC1) would show stronger associations than modifiable factors with the quality of anticoagulation control and risks for thromboembolism and hemorrhage.

Association of Paroxysmal Supraventricular Tachycardia with Ischemic Stroke: A National Case-Control Study
Cardioembolic stroke accounts for approximately 15%-20% of all ischemic strokes. Atrial fibrillation constitutes one-half to two-thirds of all cardioembolic stroke events. The association of paroxysmal supraventricular tachycardia (PSVT) with ischemic stroke remains unclear. A national case –control study was conducted to identify the risk factors, including PSVT, for ischemic stroke in Taiwan.

Left ventricular diastolic dysfunction and arterial occlusion in ischemic stroke related to atrial fibrillation
【Background】Left ventricular diastolic dysfunction lead to left atrial stasis and thus increases a risk of left atrial appendage thrombus in patients with atrial fibrillation. We investigated whether left ventricular diastolic dysfunction is associated with embolic burden in patients with ischem ic stroke related to atrial fibrillation.

Endovascular thrombectomy in a patient with acute left internal carotid artery occlusion receiving rivaroxaban
The 78-year-old female patient came to our emergency department (ED) due to acute consciousness disturbance, global aphasia and right-sided weakness onset within 3 hours. She had hypertension, persistent non-valvular atrial fibrillation treated with rivaroxaban 10 mg/day, and previous stroke with sequela of left-sided paralysis. Her pre-stroke modified Rankin Scale (mRS) was 2. NIHSS score was 32 at ED, partially contributed by previous stroke. And her creatinine clearance was 50 ml/min, international normalized ratio (INR) was 2.38.

Atrial fibrillation modifies the effect of chronic kidney disease on outcome of stroke patients potentially eligible for intravenous thrombolysis
【Background】Atrial fibrillation (Af) increases risk of stroke and is a common comorbidity in patients with chronic kidney disease (CKD). However, the interaction between Af and CKD on stroke outcome has not been determined.

Calcified Amorphous Tumor Causing Shower Embolism to the Brain: A Case Report with Serial Echocardiographic and Neuroradiologic Images and a Review of the Literature
An 89-year-old woman with chronic atrial fibrillation, hypertension, chronic heart failure, and dementia was admitted to our hospital due to multiple small cerebral and cerebellar infarctions. Transthoracic echocardiogram revealed a floating calcified mass lesion arising from the endocardium of the posterior portion of the mitral annulus with mitral annular calcification. Furthermore, the mass had a heterogeneity of the echogenicity. The mass was diagnosed as a calcified amorphous tumor based on specific echocardiographic features.
