Value of transesophageal echocardiography in device closure of perimembranous ventricular septal defects in children via ultra-minimal trans intercostal incision.

Under TEE guidance, PmVSDs were closed successfully using a concentric occluder via an ultra-minimal trans intercostal incision. TEE, which was used to assess defects and postoperative effect, effectively guide PmVSDs closure, is of great value.
