目的:探讨超声心动图在经胸微创封堵术治疗继发孔房间隔缺损中的应用价值。方法:术前经胸超声心动图(TTE)初步筛选20例单纯继发孔房间隔缺损(ASD)患者,观察各切面ASD大小及周缘情况,术中经食管超声心动图(TEE)进一步观察缺损情况,在TEE引导下进行经胸微创封堵术,术后1周、3个月随访,采用TTE观察心房水平有无残余分流、封堵器有无移位及右心系统回缩情况等。结果:20例ASD患者行经胸微创封堵术,封堵成功20例,占100%。TTE对上、下腔静脉缘的显示率为75.5%和78.6%,TEE均为100%。术后1周、3个月TTE随访,心房水平无残余分流、封堵器位置稳定,无移位,未影响周围瓣膜功能及静脉回流,右房、右室内径较术前缩小。结论:超声心动图贯穿了经胸微创封堵术治疗继发孔房间隔缺损的全程,TEE与TTE联合应用,对术前诊断与筛选、术中选择封堵器和实时监控、术后效果评价发挥了重要作用。
Objective: To investigate the value of echocardiography in the treatment of secondary atrial septal defect by minimally invasive transcatheter closure. Methods: Twenty patients with simple secondary atrial septal defect (ASD) were preliminarily selected by transthoracic echocardiography (TTE). The ASD size and perimeter of the ASD were observed. The intraoperative transesophageal echocardiography (TEE) Under the guidance of TEE transthoracic minimally invasive occlusion surgery, 1 week after surgery, 3 months follow-up, the use of TTE to observe the atrial residual flow diversion, occluder displacement and right ventricular system contraction situation . Results: Twenty patients with ASD underwent minimally invasive occlusion of the thoracic cavity. Twenty patients were successfully blocked, accounting for 100%. TTE on the superior vena cava margin of the display rate of 75.5% and 78.6%, TEE were 100%. After 1 week and 3 months after TTE follow-up, there was no residual shunt at atrial level. The occluder position was stable, no displacement and no effect on peripheral valve function and venous return. Conclusion: Echocardiography through the minimally invasive transcatheter closure of the entire process of secondary atrial septal defect, TEE and TTE combined application of preoperative diagnosis and screening, intraoperative selection of occluder and real-time monitoring, postoperative effects Evaluation plays an important role.
