ABSTRACT
OBJECTIVE@#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.@*METHODS@#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.@*RESULTS@#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.@*CONCLUSION@#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.
