We report a case of atrial fibrillation in a patient in whom a mobile thrombus in the left atrial appendage increased in size after low-dose dabigatran therapy. A 74-year-old man was admitted to our hospital because of sudden onset of right hemiplasia and dysarthria. On admission, his National Institutes of Health Stroke Scale score was three. Axial diffusion-weighted magnetic resonance images ...

right atrial dilation due to left heart disease is a common complication among adults. the present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. the results of chest x-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. during the tra...

Atrial fibrillation is the most common cardiac arrhythmia, and its prevalence is increasing. Cardioembolic stroke, most of the times secondary to thrombus formation in the left atrial appendage, is its most feared and life threatening consequence. Oral anticoagulation with vitamin-K-antagonists is currently the most used prophylaxis for stroke in patients with atrial fibrillation; unfortunately...

Restoration of sinus rhythm by electrical cardioversion is a therapeutic option in appropriately selected patients with atrial fibrillation. It is important to determine predictors of electrical cardioversion outcome in patients with atrial fibrillation. Predictive value of clinical and conventional echocardiographic parameters for predicting cardioversion outcome is limited. The role of left a...

OBJECTIVE To determine the relations between left atrial appendage function, spontaneous echo contrast, and thromboembolism in patients with different modes of permanent pacemakers. PATIENTS AND METHODS 88 patients with pacemaker implantation and 25 healthy controls in sinus rhythm had transoesophageal echocardiographic examination of the left atrial appendage. Left atrial size, appendage are...

BACKGROUND Modern pharmacological studies have confirmed that the total extract of Zhigancao Decoction, either as a single active compound or in combination, can inhibit arrhythmia. In this study, the myocardial tissue/silicon substrate microelectrode array (MEA) was used to detect the Zhigancao Decoction medicated serum of the New Zealand white rabbits right atrial appendage after rapid right ...

background: p wave dispersion (pwd) is defined as the difference between the maximum p wave duration (p max ) and the minimum p wave duration (p min ) in 12-leads of the surface electrocardiography. the aim of this study was to evaluate the values of pwd during atrial fibrillation (af) after acute myocardial infarction (ami).   methods: we prospectively evaluated atrial rhythms of 350 patients ...

Identifying independent risk factors for stroke in patients with atrial fibrillation is important for 2 main reasons: it sheds light on stroke pathogenesis associated with this common cardiac dysrhythmia, and it allows stratification of stroke risk for individual patients. Both are keys to prevention of the unduly large cardioembolic brain infarcts that complicate atrial fibrillation. Among non...
