目的:评价心腔内超声心动图(ICE)在经心导管应用Amplatzer封堵器关闭Ⅱ孔型房间隔缺损(ASD)术中的应用价值。 方法:207例Ⅱ孔型ASD患者,年龄1.83-85(32.84±24.21)岁。ASD大小分别于术前经胸超声心动图和术中ICE标准切面测量,比较二者对ASD测量值与术中球囊测得ASD延长径的相关性。 结果:207例术前经胸超声心动图测ASD直径(16.30±5.89)mm,与球囊测ASD延长径(21.36±7.32)mm,相关系数r1=0.91(P<0.05);术中ICE测值(21.49±8.04)mm,相关系数r2=0.99(P<0.01)。手术成功率99.03％。瞬时完全堵闭率89.23％,24 h完全堵闭率94.69％,全组无严重并发症。 结论:ICE测量ASD直径与球囊测量ASD延长径相关性良好;术中标准切面的建立更易于清晰显示ASD大小,形态,周边结构;无需全麻,提高了经导管关闭ASD手术的安全性及成功率。
Objective: To evaluate the value of intracardiac echocardiography (ICE) in the closure of type Ⅱ atrial septal defect (ASD) with transcatheter Amplatzer occluder. Methods: A total of 207 patients with type Ⅱ ASD were aged 1.83-85 (32.84 ± 24.21) years. ASD size were measured by preoperative transthoracic echocardiography and intraoperative ICE standard sections, and the correlation between ASD measurements and intraoperative balloon ASD extension was compared. Results: The preoperative transthoracic echocardiography was used to measure the diameter of ASD (16.30 ± 5.89) mm, and the diameter of ASD was (21.36 ± 7.32) mm, the correlation coefficient r1 was 0.91 (P <0.05). The ICE (21.49 ± 8.04) mm, the correlation coefficient r2 = 0.99 (P <0.01). Surgical success rate was 99.03%. Instantaneous complete blocking rate of 89.23%, 24 h completely blocking rate of 94.69%, the whole group without serious complications. CONCLUSIONS: The correlation between the ASD diameter measured by ICE and the diameter of ASD measured by balloon is good. The setting of the standard section in operation is easier to clearly show the size, shape and peripheral structure of ASD. It also improves the safety of ASD without catheter and general anesthesia.
