Text Extraction

Background. Atrial fibrillation is the most common arrhythmia in patients older than 40 years-old, and it significantly increases the risk of stroke. In patients with atrial fibrillation, the left atrial appendage excision during cardiac surgery is one of the suggested surgical procedures to avoid thrombus formation and risk of systemic embolization. Objective. To determine prevalence of stroke after cardiac surgery with or without left atrial appendage excision in patients with atrial fibrillation. Material. Thirty-one patients with atrial fibrillation underwent cardiac surgery from January, 2020 and July, 2021 were included. They were divided into two study groups, with and without left atrial appendage excision. Relevant variables between groups were: Postoperative major bleeding, stroke and death. Results were analyzed by descriptive statistics, X2 and Student’s t-distribution. Results. Ten patients were included in the excision group and 21 in non-excision group. The indications for cardiac surgery were mainly valvular surgery, especially mitral valve operations. Two patients without left atrial appendage excision (9.5%) developed stroke, but none of the patients in the excision group (p=0.320). Patients with excision developed more events such as postoperative major bleeding and mortality, though without statistically significant difference. Conclusions. There was no statistically significant difference regarding occurrence of stroke in patients with atrial fibrillation undergoing cardiac surgery with or without left atrial appendage excision. A limitation of this study is the small sample size; therefore, we recommend to continue this study including a mayor number of patients.
