The case of the furtive finding: atypical atrial flutter
A patient’s arrhythmia was identified only after an electrocardiogram (ECG) lead was attached directly to an atrial epicardial lead. The 87-year-old man had a history of paroxysmal atrial fibrillation, coronary artery disease, and severe mitral and tricuspid regurgitation and was admitted for corrective cardiac surgery. His history included a cardioembolic stroke 10 months prior to admission, hypertension, and hyperlipidemia. He underwent coronary artery bypass grafting (CABG) to the right coronary artery, bioprosthetic mitral valve replacement, tricuspid annulus repair, and a maze cryoablation or cryomaze procedure.

History of Thyroid Disorders in Relation to Clinical Outcomes in Atrial Fibrillation: A Cohort Study
Atrial fibrillation is the most common cardiac complication of hyperthyroidism. The association between history of hyperthyroidism and stroke remains unclear. We sought to determine whether history of thyroid dysfunction is a thromboembolic risk factor in patients with atrial fibrillation.

Commentary: TIA for the internist
A few times a year an internal medicine colleague asks, “Can you tell me TIA (transient ischemic attack) in a nutshell?” With the new stroke and TIA guidelines coming out this May,1 the below case is all too familiar. A 64 year-old man with a history of hypertension comes in for an urgent care visit. Three days ago he awoke with left arm weakness; he could not open doors or lift things, but symptoms fully resolved by early afternoon. He had no pain or other symptoms, he is normotenisve on medication.

Hypoglycemic Hemiparesis: The Stroke Masquerader
The classic presentation of hypoglycemia involves Whipple's triad of signs and symptoms of hypoglycemia, low plasma glucose, and resolution of symptoms with correction of glucose derangement.1 Findings in hypoglycemia are classified as either neuroglycopenic or autonomic.2 Whereas some are synonymous with hypoglycemia and allow prompt recognition and treatment, there are other manifestations of hypoglycemia that are relatively uncommon, such as hemiparesis, which can be mistakenly attributed to other etiologies.

SAME-TTR score, time in therapeutic range and outcomes in anticoagulated patients with atrial fibrillation
Oral anticoagulation is highly effective preventing stroke and mortality in non-valvular atrial fibrillation patients. However, the efficacy and safety of vitamin K antagonists, the main oral anticoagulation drug used) strongly depends upon the quantity of anticoagulation control, as reflected by the average percentage of the time in therapeutic range of INR (International Normalised Ratio) 2.0-3.0. An easy, simple prediction of which atrial fibrillation patients are likely to do well on vitamin K antagonists (with good average time in therapeutic range) could guide decision-making between using vitamin K antagonists (eg.

However, the efficacy and safety of vitamin K antagonists (the main oral anticoagulation drug used) strongly depends upon the quantity of anticoagulation control, as reflected by the average percentage of the time in therapeutic range of international normalized ratio 2.0-3.0.
