摘要
目的 :评价用Amplatzer封堵器封堵房间隔缺损患者术后和随访期心脏结构和功能的改变。方法 :入选病例 14例 ,房间隔缺损直径为 9～ 37( 2 2 7± 10 6 )mm。分别于术前、术后 1周和随访期 (平均 16 4±9 7个月 )行超声心动图检查 ,测量相关数据。结果 :与术前比较 ,术后及随访期右心室内径缩小 ,三尖瓣口、肺动脉瓣口血流峰值和肺动脉收缩压明显降低 (P <0 0 5～0 0 1) ,有显著性差异。未发现房室瓣和腔静脉梗阻以及主动脉壁受压 ,无新出现的心律失常和脑栓塞等并发症。结论 :房间隔缺损封堵术在消除异常分流的同时可有效改善右心高容量负荷状态 ,降低肺动脉高压 。
Objective:To evaluate the changes of cardiac structure and function before and after transcatheter closure of atrial septal defect(ASD). Methods:Fourteen ASD patients were enrolled in our study.The mean diameter of ASD was 22.7±10.6(range 9-37)mm.The operation was performed successfully by Amplatzer closure device.Echocardiography and other related examinations were performed before,one week after operation and during the follow-up. Results:The peak blood velocity of tricuspid valves and pulmonary aortic valves was significantly decreased after operation and during the follow-up (p<0.05-0.01).The pulmonary artery systolic pressure was also significantly decreased (p< 0.01).The right heart became smaller than that before operation(p<0.01).No obstructed atrial-ventricular valves and vena cava,or the pressed aortic wall were found.No complications such as arrhythmia,cerebral embolism were noted. Conclusions:ASD closure device not only can eliminate the abnormal shunt,but also can improve the high-volume load of the right heart.It can effectively decrease the pulmonary hypertension and make the enlarged right heart reduced.
