This study was done to determine the feasibility, efficacy, and safety of the repair of ventricular septal defects using a minimally invasive mehtod. From Mar. 1997 to Dec. 1998, eighty0four patients underwent repair for ventricular septal defects (Male:Female=44:40). From ages ranged from 3 months to 10 years, with a mean age of 3.8±3.4 years. From a 4-6 cm lingitudinal rifgt parasternal incision, the pericardial cavity was entered through a division of the 3rd to 5th costal cartilages. Cardiopulmunary bypass was initiated after superior, inferior vena cava and ascending aortic cannulations. The aorta was cross-clamped and antergrade cardioplgia was administered. All the defects were successfully repaired through the right atrium or pulmonary trunk. There were no mortalities. All patients recovered from the operation rapidly. Cardiopulmonary bypass and ischemic times averaged 59.8±20.8 and 38.4±18.6 minutes, respectively. There were no significant dufferences in cardiopulmonary bypass time, ischemic time, ICU stay, hospitalization stay, extubation time, or chest tube frainage compared with 42 patients undergoing conventional median sternotomy ventricular septal defect repairs. Our experience demonstrates that a 5 cm small right parasternal minimally invasive approach can be used safely and effectively for the repair of ventricular septal defects in infants and children with cosmetic wound healing. |
