  • Objective 

    To investigate the application of transesophageal echocardiography in the evaluation of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation.

    Methods 

    Eighty patients with patent foramen ovale were selected as the study objects, and were divided into atrial fibrillation group (n=44) and non-atrial fibrillation group (n=36), and 30 healthy subjects were selected as control group. Transesophageal echocardiography was performed in three groups. The left atrial appendage volume and changes of function in three groups were compared.

    Results 

    The left atrial appendage maximum volume (LAAVmax), left atrial appendage minimum volume (LAAVmin), left atrial appendage opening maximum area (MA) and left atrial appendage opening maximum length diameter (MD) in the atrial fibrillation group and non-atrial fibrillation group were significantly higher, and the left atrial appendage maximum emptying velocity (LAAeV) and left atrial appendage maximum filling velocity (LAAfV) were significantly lower than those of the control group (P < 0.05). The LAAVmax, LAAVmin as well as MA and MD of left auricular opening in patients with left auricular spontaneous imaging (SEC) in the atrial fibrillation group were significantly higher than those in the non-atrial fibrillation group, and LAAeV and LAAfV were significantly lower than those in the non-atrial fibrillation group (P < 0.05). After treatment, the incidence of end-point events in the atrial fibrillation was significantly higher than that in the non-atrial fibrillation group (P < 0.05).

    Conclusion 

    The application of transesophageal echocardiography in the evaluation of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation is effective. The left atrial appendage function of patients with atrial fibrillation is worse than that of patients without atrial fibrillation.
