Objective |
We sought to investigate whether left atrial (LA) appendage (LAA) function was impaired in patients with systemic embolism in sinus rhythm.
Methods |
Transesophageal echocardiography was performed in 7 patients within 5 days after embolism (early group) and in 32 patients, more than 5 days after embolism (late group). We searched intracardiac thrombus and determined LAA area and LAA flow velocity, and the grade of spontaneous echocontrast.
Results |
LA thrombus could be detected in 2 of the 39 patients only in early group (P = .028). The patients of early group, as compared with late group, had lower LAA flow velocity (28 ± 16 vs 60 ± 26 cm/s, P = .007) and higher grade of spontaneous echocontrast score (1.14 ± 1.46 vs 0.25 ± 0.62, P = .013). LA dimension and LAA area were not statistically different.
Conclusion |
LAA function may be impaired early after embolism even in sinus rhythm.
