Application of improved wire - maintaining technique in performing transcatheter closure of ventricular septal defects：a clinical study / 介入放射学杂志

ABSTRACT

Objective To discuss the clinical efficacy and safety of improved wire- maintaining technique in performing transcatheter closure of ventricular septal defects. Methods During the period from June 2011 to June 2013 at Changhai Hospital, percutaneous transcatheter closure of ventricular septal defect with improved wire-maintaining technique was carried out in 62 patients. According to the manipulation used , the patients were divided into traditional wire-maintaining technique group (group A, n = 30) and improved wire- maintaining technique group (group B, n = 32). The use of occluder during the procedure, the fluoroscopy time, the operation time and the complications were recorded. Follow-up examinations with ECG, echocardiogram and chest radiograph were performed at 24 hours and at 1 , 3 and 6 months after the procedure. The results were analyzed. Results No statistically significant differences in the use of occluder and in the incidence of complications existed between the two groups (P > 0.05). No severe complications occurred in both groups. The fluoroscopy time and the operation time in group A were (11.96 ± 3.63) min and (53.43 ± 14.48) min respectively, while the fluoroscopy time and the operation time in group B were (9.37 ± 2.77) min and (45.34 ± 10.38) min respectively, and the differences between the two groups were statistically significant (P < 0.05). Conclusion In performing transcatheter closure of ventricular septal defects, the practice.
