摘要

To discuss the suitable types of ventricular septal defects for asymmetric occluders, and elucidate the critical role of echocardiography in choosing occluders, guiding successful occlusion and avoiding injury during operation.We retrospectively studied 179 patients with ventricular septal defects who received minimal-invasive surgical device closure with asymmetric occluder. We analyzed the types, size and morphology of ventricular septal defects suitable for asymmetric occluders. The therapeutic efficiency was evaluated by follow-ups.Out of the 179 successful cases treated with asymmetric occluders, 86.59% had perimembranous ventricular septal defects, and double-committed sub-arterial ventricular septal defects accounted for 13.41%. In general, the size of occluders to be selected was the maximum diameter of the defects plus 2-3 mm. Follow-ups showed that occluders were placed and fixed properly. No severe residual shunt, valve regurgitation or heart block were discovered.Application of asymmetric occluders expands the range of indications for occlusion via small chest incision. Accurate echocardiography helps to improve the safety and successful rate of the surgery.
