|Condition or disease||Intervention/treatment||Phase|
|Ventricular Septal Defect||Device: Fully Absorbable VSD Occlusion System Device: VSD Occluder||Not Applicable|
- This is a prospective, multicenter, randomized and noninferiority clinical trial, which is designed to compare the effectiveness and safety with the fully absorbable ventricular septal defect (VSD) occlusion system and VSD occlusion system produced by Shanghai shape memory alloy materials co., LTD.
- This trial will recruit about 108 subjects from 4 centers. Patients will be randomized to two groups in equal proportion (54 in each). The proposal recruiting period is 12 months and the follow-up will be performed at 1 month, 3 months and 6 months after surgery.

Experimental: Treatment Group
Experimental group is allocated to use novel fully degradable ventricular septal defect closure system manufactured by Shanghai shape memory alloy materials co. LTD.
Device: Fully Absorbable VSD Occlusion System
Under echocardiography guided treatment of VSD with a novel fully degradable clolsure system
Active Comparator: Control Group
Control Group is allocated to use Interposition conveying device for ventricular septal defect closure produced by Shanghai shape memory alloy material co. LTD.
Device: VSD Occluder
Under echocardiography guided treatment of VSD with commercially available occluder.
- success rate of occlusion at 6 months after the surgery [ Time Frame: 6 months after the surgery ]Successful occlusion is that when follow-up under echocardiography at 6 months after surgery, the occlusion site shows no residual shunt or only a small amount of residual shunt.
- Surgical technique success rate [ Time Frame: Immediately after surgery ]After the occluder was implanted with surgical intervention transport device (test group) or occluder and intervention transport device (control group), the occluder was released safely.
- technique success rate [ Time Frame: Immediately after surgery ]After the occluder was implanted with occluder and surgical intervention transport device (test group) or occluder and intervention transport device (control group), the occluder was released safely and no occluder detachment occurred during the operation.
