Brief Summary:
Ventricular septal defect (VSD) is one of the most common pediatric congenital malformations. In recent years, in view of the rapid rise of transthoracic minimally invasive hybrid closure for pediatric VSD in the clinical practice, precision assessment of perioperative its effectiveness and safety has already become an important issue that must be solved. On the basis of echocardiography, integrating with characteristics associated critical care, the investigators focus on precision assessment of perioperative effectiveness and safety of transthoracic hybrid closure for pediatric VSD, compared with conventional surgical sternotomy repair with cardiopulmonary bypass (CPB).

Arm Intervention/treatment
Active Comparator: Off-pump hybrid closure
Hybrid closure is that a periventricular technique uses an occluding device to closure ventricular septal defects of patients through the delivery system by transthoracic minimally invasive small incision without cardiopulmonary bypass.
Drug: sufentanil anesthesia
Anaesthesia is maintained by inhaled isoflurane in concentrations 0.7-0.8 % end-tidal with additional sufentanil injected during surgery, as required. During extracorporal circulation patients receive isoflurane via a vaporizer incorporated in the extracorporeal gas supply in the same concentrations.
Other Name: Sufentanil, Sufenta, (R-30730)

Procedure: Hybrid closure
Hybrid closure of ventricular septal defects through the delivery system without cardiopulmonary bypass by transthoracic minimally invasive small incision.
Other Name: TTMI: Transthoracic Minimally Invasive

Placebo Comparator: Control
Control group: Conventional closure of ventricular septal defects was aided with cardiopulmonary bypass.
Drug: sufentanil anesthesia
Anaesthesia is maintained by inhaled isoflurane in concentrations 0.7-0.8 % end-tidal with additional sufentanil injected during surgery, as required. During extracorporal circulation patients receive isoflurane via a vaporizer incorporated in the extracorporeal gas supply in the same concentrations.
Other Name: Sufentanil, Sufenta, (R-30730)

Procedure: Control
Surgical closure of ventricular septal defects with cardiopulmonary bypass by routine open thoracotomy.
Other Name: CPB: cardiopulmonary bypass
