Objective To analyze the effect of domestic made two-disk-like VSD occluder device, on membranous aneurysm ventricular septal defect （VSD）. Methods Forty-eight patients with membranous aneurysm VSD from march 2008 to may 2008 was included. They were all treated with transcatheter occlusion by domestic two-disk-like occluder. EKG and ultrasoundeardiogram were performed about 1,3,6 months and 1 year after the therapy. Results Occlusion was successfully performed in 46 patients,the success rate of the group was 95.8% （46of48） ,2 cases with more holes could not be closed. The defection of right surface on the septum was closed in 36 cases,LVG showed that 42 patients had complete immediate closttre;4 patients had a small shunt immediately after the procedures. TIE revealed that there were no residual shunts in all pa- tients 3 months after the procedure. 1 patient suffered from cerebral embolism in the procedure and recovered in 2 months; 1 patient suffered from spasmodic Ⅲ atrial ventricular block and returned to normal 3d after medication. Conclusion Transcatheter closure of membranous anertrysm VSD using this domestic occluder is safe and effective, It is necessary to choose appropriate technique of closure according to the shape, size and conditions of ventricular septal aneurysm during the interventional procedure in order to achieve the best efficacy.
