摘要
目的分析经食管超声心动图检查(TEE)评估不同类型房颤患者左心耳(LAA)结构和收缩功能的价值。方法选取无锡市人民医院2018年10月至2019年9月就诊治疗的57例房颤患者,其中37例持续性房颤患者,设为持续性房颤组,另20例为阵发性房颤患者,设为阵发性房颤组,行TEE检查,比较2组左LAA相关结构及血流动力学参数,2组左房、右心耳(SEC)以及泥浆样改变发生率,比较2组BMI及CHADS2评分。结果与持续性房颤组对比,阵发性房颤组LAA最大开口径、LAA最大深度、LAD指标均较低,而Pev-LAA、Pfv-LAA、LVDd、EF指标较高,阵发性房颤组左房、LAASEC以及泥浆样改变的发生率分别为16.22%、0,低于持续性房颤组的发生率72.97%、18.92%;与持续性房颤组对比,阵发性房颤组BMI、CHADS2评分较低(P<0.05)。结论房颤患者左房及LAA结构和功能的改变是血栓形成的基础。TEE能准确检出房颤患者LAA血栓,评估LAA结构和功能状态,为临床提供了预测血栓形成的参考依据。
Objective To evaluate the value of TEE in evaluating left atrial appendage structure and systolic function in patients with different types of AF.Methods A total of 57 patients with AF who were treated in Wuxi People's Hospital from October 2018 to September 2019 were selected.Among them,37 patients with persistent AF were assigned to the persistent AF group and the other 20 were patients with paroxysmal AF.It was set up in the paroxysmal atrial fibrillation group,and TEE examination was performed.The LAA-related structures and hemodynamic parameters of the two groups were compared,and the left atrial and right atrial appendage SEC,thrombosis,and stroke risk of the two groups were compared.Results Compared with the persistent atrial fibrillation group,the maximum LAA opening caliber,maximum LAA depth and LAD indexes were lower in the paroxiral atrial fibrillation group,while the indexes of pev-laa,pfv-laa,LVDd and EF were higher.The incidence of left atrial fibrillation,LAASEC and mud sample changes in the paroxiral atrial fibrillation group was 16.22%and 0,respectively,lower than that in the persistent atrial fibrillation group(72.97%and 18.92%,respectively).Compared with the persistent af group,the BMI and CHADS2 scores of the paroxysmal af group were lower(P<0.05).Conclusion The structural and functional changes of left atrium and left atrial appendage in patients with AF are the basis of thrombosis.TEE can accurately detect left atrial appendage thrombus in patients with atrial fibrillation,assess the structure and functional status of left atrial appendage,and provide a reference for predicting thrombosis in clinical practice.
