| description | Objective The left atrial appendage is the most source of thrombus formation in atrial fibrillation.The aim of this study was to find out left atrial appendage functions in patients with PAF with or without stroke.Materials and Methods This study included74 paroxysmal atrial fibrillation patients who were performed transesophageal echocardiography for evaluation of stroke or who have suspicion doubt of atrial septal defect and patent foramen ovale. All patients had undergone 24 hours electrocardiography Holter recorder, 2 dimensional echocardiography, transesophageal echocardiography.Results Thereare no differences between the groups for diabetes, hypertension, smoking, hyperlipidemia and creatinine levels. Patients with stroke group had lower left atrial appendagefilling velocity (26.8±5, 38.9±5) (p lt;0.001), had lower left atrial appendagecontraction velocity (30.8±6, 46.6±7) (p lt;0.001) and had bigger left atrial appendagearea (2.7±0.6, 2.4±0.4) (p=0.03) than without stroke group. Left atrial appendagecontraction velocity (p=0.013) and filling velocity (p=0.045) are the independent predictors of stroke.Conclusion Our findings showed that stroke is associated with low filling velocity and low contraction velocity of left atrial appendage. Our findings suggest that this indices are independent predictors of stroke. If these results are confirmed in future studies, patients with paroxysmal atrial fibrillation without stroke and with low filling velocity and low contraction velocity of left atrial appendageshould receive more medical attention, to reduce unfavorable outcomes. |
