Summary

Stroke remains the most dangerous and frightening complication of atrial fibrillation (AF). Numerous factors predisposing to peripheral embolism in patients with AF have been well defined, documented and included in the CHA2DS2VASC score. Although proper anticoagulation minimizes the risk attributable to "known" risk factors, stroke may still occur. Thus, "unknown" risk factors may play an important role in stroke risk stratification in patients with AF. The investigators assume that one of the important "unknown" risk factor is left atrial appendage (LAA) morphology. The ASSAM study is planned to include 100 patients after ischemic stroke or transient ischemic attack (TIA) and known status of anticoagulation at the time of stroke. The control group will consist of 100 patients scheduled for AF ablation without a history of stroke or TIA.

Conditions

• Ischemic Stroke

Interventions

Type	Name	Description
RADIATION	computed tomography	CT angiography will be performed with a dual-source CT scanner using prospective ECG gating, with detector collimation of 128x0.6 mm, a gantry rotation time of 280 ms, tube voltage of 100-120 kV, tube current of 280-380 mAs depending on the patient's body mass.
