A study on eccentric occluder via ultra minimal incision of doubly committed subarterial ventricular septal defects.

TEE-guided intercostal DCS-VSD occlusion is safe and effective. There is no statistical difference between two approach with the operation time, chest opening and closing time, occluder placing time, and postoperative hospital staying. At the same time, the surgical incision by intercostal incisionis smaller and the operation invasion is less, it is a surgical approach which worth to develop.
