Endovascular thrombectomy and left atrial appendage evaluation for recurrent cerebral embolism case with atrial fibrillation early after administration of intravenous tissue plasminogen activator
ConclusionsAttention should be paid to ischemic stroke recurrence as a complication of IV t-PA, and preparation for mechanical thrombectomy is warranted. Further study of the left atrial appendage is needed to clarify the mechanisms of onset.

Anticoagulant management by low-dose of low molecular weight heparin in patients with nonvalvular atrial fibrillation following hemorrhagic transformation and complicated with venous thrombosis: Five case reports and literature review
For patients with nonvalvular atrial fibrillation (NVAF) following hemorrhagic infarction (HI)/hemorrhage transformation (HT) and complicated with venous thrombosis, the management of anticoagulation is controversial. Our study intends to explore the safety and effectiveness of using low-dose of low molecular weight heparin (LMWH) to treat NVAF patients with HI (or HT) and complicated with venous thrombosis. Between January 2018 and January 2019, NVAF related acute ischemic stroke patients with HT/HI, hospitalized in the department of neurology or rehabilitation in our hospital, are enrolled retrospectively. Among them,...

Predictors of asymptomatic cerebral infarction associated with radiofrequency catheter ablation for atrial fibrillation using an irrigated-tip catheter
Conclusion The presence of SEC and procedure duration prior to heparin injection are determinants of asymptomatic CI during AF ablation despite the use of an irrigated-tip catheter.

Subtle Post-Procedural Cognitive Dysfunction After Atrial Fibrillation Ablation
ConclusionsAblation for AF is associated with a 13% to 20% prevalence of POCD in patients with AF at long-term follow-up. These results were seen in a patient population with predominant CHADS2 (Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, previous Stroke/transient ischemic attack) scores of 0 to 1, representing the majority of patients undergoing ablation for AF. The long-term implications of these subtle changes require further study.

Results of percutaneous closure of patent foramen ovale with the GORE ® Septal Occluder
Conclusion. PFO closure with the GSO is accompanied by a high technical success rate and closure rates similar to other currently used devices. The incidence of atrial fibrillation was higher than reported with most other devices. This may be a chance finding but warrants further investigation in larger trials. © 2013 Wiley Periodicals, Inc.

Autism in the Son of a Woman with Mitochondrial Myopathy and Dysautonomia: A Case Report
Conclusion Given emerging evidence that mitochondrial dysfunction, particularly in the electron transport chain needed for cellular energy production, is an underlying pathophysiological mechanism for some varieties of ASD, clinicians should have a high index of suspicion for mitochondrial disease, especially when they encounter a patient with unusual neurological or constitutional symptoms. The prevalence of mitochondrial disease in ASD patients may be as high as five percent, which means that it is not the “zebra”[27] diagnosis that it might be in a non-ASD patient, where prevalence is about 0.01 percent.10 Reference...

Real-time phase contrast magnetic resonance imaging for assessment of haemodynamics: from phantom to patients
Conclusions The real-time sequence is accurate compared to conventional segmented PC-MRI. Its applicability in Afib was shown. Real-time PC-MRI might become a valuable tool in arrhythmia. Key Points • Assessment of haemodynamics is crucial in many cardiac diseases. • Arrhythmias are a major limitation of conventional techniques in cardiac magnetic resonance. • A real-time technique, which allows application in arrhythmia, was validated. ...

Prediction of atrial fibrillation development and progression: Current perspectives.
Abstract Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. Several conventional and novel predictors of AF development and progression (from paroxysmal to persistent and permanent types) have been reported. The most important predictor of AF progression is possibly the arrhythmia itself. The electrical, mechanical and structural remodeling determines the perpetuation of AF and the progression from paroxysmal to persistent and permanent forms. Common clinical scores such as the hypertension, age ≥ 75 years, transient ischemic attack or stroke, chronic obstructive pulmonary disease, and ...

Association of platelet-to-lymphocyte ratio with silent brain infarcts in patients with paroxysmal atrial fibrillation.
In this study, we aimed to evaluate whether the inflammation as measured by increased platelet to lymphocyte ratio (PLR) predispose to silent infarcts in patients with paroxysmal atrial fibrillation (PAF). METHODS: The present study investigated a total of 48 new diagnosed patients with PAF who had no signs of stroke. PLR, which was calculated as the ratio of the platelet count to the lymphocyte count, C-reactive protein and erythrocyte sedimentation rate were measured due to evaluate inflammatory state. Magnetic resonance imaging (MRI) was performed to evaluate the presence of silent brain infarcts (SBIs) in patients....

Multiple Cerebral Infarcts in a Young Patient Associated With Marijuana Use
Cerebrovascular events associated with marijuana use have been reported previously. This association is plausible, but not well-established yet. A 14-year-old girl, long-term heavy cannabis user, presented with generalized tonic-clonic seizures and decreased level of consciousness a few hours after smoking cannabis. Brain magnetic resonance imaging showed multiple areas of acute, subacute and chronic ischemic lesions in the left frontal lobe, basal ganglia, and corpus callosum. History of other illicit drug use and other known causes of stroke were ruled out. Cannabis might cause stroke through direct effects on the cerebr...

Cardiovascular disease and brain health: Focus on white matter hyperintensities
Publication date: June 2018 Source:IJC Heart & Vasculature, Volume 19 Author(s): Francesco Moroni, Enrico Ammirati, Maria A. Rocca, Massimo Filippi, Marco Magnoni, Paolo G. Camici Diseases affecting the brain contribute to a substantial proportion of morbidity and mortality in the general population. Conditions such as stroke, dementia and cognitive impairment have a prominent impact on global public health. Despite the heterogeneous clinical manifestations of these conditions and their diverse prognostic implications, current evidence supports a role for cardiovascular disease as a common pathophysiological groun...
