摘要
目的:应用经食管三维和经胸超声心动图评价房颤患者左心耳及左心房容积与功能。方法:将112例房颤患者分为阵发性房颤(paroxysmal atrial fibrillation,ParAF)组(80例)和持续性房颤(persistent atrial fibrillation,PerAF)组(32例),对照组为40例非房颤患者。收集各组临床资料,经胸超声心动图测量左心房前后径(LAD),左心房容积(LAV),左室舒张末期容积(LVEDV),左室收缩末期容积(LVESV);经食管三维超声心动图测量左心耳最大排空速度(LAAeV),左心耳最大充盈速度(LAAf V),左心耳最大容积(LAAVmax),左心耳最小容积(LAAVmin);计算左心房容积指数(LAVI),左室射血分数(LVEF),左心耳射血分数(LAAEF)。结果:与对照组比较,ParAF组的LAAEF,LAAeV,LAAf V明显降低,LAD,LAV,LAVI,LAAVmax, LAAVmin明显增大(P<0.05);与ParAF组相比,PerAF组的LAAEF,LAAeV,LAAf V亦明显降低,LAD,LAV,LAVI,LAAVmax,LAAVmin亦明显增大(P<0.05);两组LVEDV, LVESV,LVEF差异均无统计学意义(P>0.05)。结论:经胸超声心动图评估能证实房颤患者左心房容积增大,经食道三维超声心动图评估能证实房颤患者左心耳扩大,提示左心耳功能减低,且Per AF患者变化更为显著。
Objective: To evaluate the volume and function of left atrium and left atrial appendage in patients with atrial fibrillation by three-dimensional transesophageal echocardiography and transthoracic echocardiography. Methods: A total of 112 patients with atrial fibrillation were divided into two groups: a paroxysmal atrial fibrillation (ParAF) group (n=80) and a persistent atrial fibrillation (PerAF) group (n=32). Control group was people without atrial fibrillation (n=40). Clinical data of the participants were collected. Left atrial dimension (LAD), left atrial volume (LAV), left ventricular enddiastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV) were measured by transthoracic echocardiography, while left atrial appendage peak emptying flow velocity (LAAeV), left atrial appendage peak filling flow velocity (LAAf V), left atrial appendage maximum volume (LAAVmax) and left atrial appendage minimum volume (LAAVmin) were measured by threedimensional transesophageal echocardiography. Left atrial volume index (LAVI), left ventricular ejection fraction (LVEF) and left atrial appendage ejection fraction (LAAEF) were calculated. Results: Compared with the control group, LAAEF, LAAeV and LAAf V in the ParAF group were decreased obviously, while LAD, LAV, LAVI, LAAVmax and LAAVmin in the ParAF group were increased obviously (P<0.05). Compared with the ParAF group, LAAEF, LAAeV and LAAf V in the PerAF group were also decreased obviously, and LAD, LAV, LAVI, LAAVmax and LAAVmin in the ParAF group were also increased obviously (P<0.05). There was no statistically significant difference in LVEDV, LVESV, LVEF between the ParAF group and the PerAF group (P<0.05). Conclusion: Left atrium and left atrial appendage were enlarged and the function of left atrial appendage was declined in patients with AF, and the changes were more obvious in patients with PerAF compared with patients with ParAF by three-dimensional transesophageal echocardiography and transthoracic echocardiography.
