This study evaluates the value of transesophageal echocardiography (TEE) combined with speckle tracking imaging in predicting the recurrence of atrial fibrillation (AF) after radiofrequency ablation. A total of 269 patients with paroxysmal AF were divided into 2 groups according to the clinical follow-up results: the recurrence group (n = 79) and the non-recurrence group (n = 190). Left atrial appendage flow velocity was measured by TEE, left atrial anteroposterior diameter, left atrial volume index and CAAP-AF score were measured by conventional TEE, and left atrial reservoir phase strain, left atrial pipeline phase strain and left atrial pump phase strain were measured by speckle tracking imaging. The correlation between each parameter and recurrence was compared. Logistic regression analysis showed that left atrial reservoir strain and left atrial appendage flow velocity were sensitive indicators to predict the recurrence of paroxysmal AF after radiofrequency ablation. Ultrasound parameters can be used to screen the patients who are prone to recurrence after operation and provide reference for clinical treatment to reduce the recurrence rate.
本研究评估经食管超声心动图（TEE）联合斑点追踪成像在预测射频消融术后心房颤动（AF）复发中的价值。将269例阵发性AF患者根据临床随访结果分为2组：复发组（n = 79）和未复发组（n = 190）。通过TEE测量左心耳流速，通过传统TEE测量左房前后径、左房容积指数和CAAP-AF评分，通过斑点追踪成像测量左房储存期应变、左房管道期应变和左房泵血期应变。比较各参数与复发之间的相关性。Logistic回归分析显示，左房储存期应变和左心耳流速是预测射频消融术后阵发性AF复发的敏感指标。超声参数可用于筛选术后易复发的患者，为临床治疗提供参考以降低复发率。
