经导管封堵治疗50例室间隔缺损的疗效和安全性

目的:观察应用室间隔缺损封堵器经导管介入封堵先天性室间隔缺损(VSD)的疗效和安全性。方法：50例VSD患者术前由经胸超声心动图确诊，在透视及经胸超声心动图监视下经导管置入室缺封堵器封堵VSD，术后1, 3, 6个月分别行经胸超声心动图、心电图评价治疗效果。结果：50例VSD患者术中经左心室造影明确缺损直径为1.8～13.4（5.54±2.75）mm，封堵成功率96.0％（48/50），手术并发症发生率为16.7％（8/48），封堵术后3个月超声复查左室舒张末径较术前明显缩小。结论：经导管封堵VSD是一种成功率较高、并发症少、创伤小、疗效可靠的介入治疗方法。

Therapeutic effect and safety of transcatheter occlusion of ventricular septal defects in 50 patients

OBJECTIVE: To determine the therapeutic effect and safety of transcatheter closure of ventricular septal defects (VSD) in 50 patients. METHODS: Fifty patients were diagnosed by transthoracic echocardiography. To perform the operation, transthoracic echocardiography and X ray were used continuously to monitor the procedure. Transthoracic echocardiography and ECG were performed at 1, 3, and 6 months after the operation to evaluate the therapeutic effect. RESULTS: The VSD diameter ranged from 1.8 to 13.4 (5.54 +/- 2. 75) mm. The successful rate of the operation was 96.0%, and the complication rate of the operation was 16.7%. A 3 month follow-up was completed in 20 patients, and the median left ventricle end-diastolic dimension significantly decreased from (40.20 +/- 8.80) mm to (32.90 +/- 8.36) mm (P < 0.001). CONCLUSION: Transcatheter closure of ventricular septal defects is a good method with a high success rate of placement, fewer complications, and a good occlusion effect.
