摘　　要：本文探究320排CT在先天性心脏病(CHD)介入治疗中的应用价值。选取66例CHD患者为研究对象进行回顾性研究,其中,房间隔缺损(ASD)33例,室间隔缺损(VSD)33例。患者均分别于介入封堵手术术前和术后行经胸超声心动图(TTE)、320排CT心脏四维容积动态成像(4D-CCTA)检查。结果显示,术前TTE、4D-CCTA测量ASD和VSD最大径与封堵器腰部直径(POS)的差值小于TTE测量的差值(P<0.05);术前TTE、4D-CCTA测量的ASD和VSD最大径与POS、所选封堵器型号均存在良好相关性(P<0.05),且后者相关性更高;4D-CCTA测量CHD患者术后EF、EDVI、ESVI、SVI、CI均低于TTE测量数据(P<0.05)。320排CT能准确测量CHD患者术前ASD和VSD大小、间隔总长,有助于指导医生选择封堵器型号,且能准确评估患者术后左心功能。This study explored the application value of 320-slice CT in the interventional therapy for congenital heart disease(CHD).A retrospective study was carried out in 66 patients with CHD,including 33 cases of atrial septal defect(ASD)and 33 cases of ventricular septal defect(VSD).All patients underwent transthoracic echocardiography(TTE)and 320-slice CT four-dimensional volume dynamic imaging(4D-CCTA)before and after interventional occlusion surgery.The results showed that the difference between the maximum diameter of ASD,VSD and the waist diameter(POS)of the occluder measured by preoperative TTE and 4D-CCTA was smaller than the difference measured by TTE(P<0.05).The maximum diameter of ASD and VSD measured by preoperative TTE and 4D-CCTA both had a good correlation with POS and the selected type of occluder(P<0.05),and the latter had a higher correlation.The postoperative EF,EDVI,ESVI,SVI,and CI of CHD patients measured by 4D-CCTA were lower than those data measured by TTE(P<0.05).It can be seen that 320-slice CT could accurately measure the size of preoperative ASD and VSD,and total interval length of CHD patients,which could be helpful to guide doctors in selecting the type of occluder,and accurately evaluate the left ventricular function of patients after operation.
