Abstract:
Objective To summarize and evaluate our surgical approach of tetralogy of Fallot with complete atrioventricular septal defect.Methods 11 patients underwent surgical correction at our institute between June 2007 and April 2012.All of the 11 patients received biventricular or partial biventricular repair through a combined right atrial and right ventricular outflow tract approach.Two-patch technique was used in all 11 children.To minimize the incision in the right ventricular outflow tract(ROVT),8 patients underwent a transatrial approach to close ventricular septal defect.A transannular patch was needed in 7 patients,and a monocuspid valve was inserted in 1 of these patients.Results One hospital death occurred during intensive care stay due to severe low cardiac output syndrome and one late death took place six months after operation because of pneumonia and heart failure.The mean follow-up time was (21.20 ± 19.08) months (range,3-60 months).The KaplanMeier curve for the survival rate was 79.5％ at 5 years.Several postoperative complications occurred during the first 3 months,including 1 mild RVOT obstruction and 1 pulmonary artery stenosis,2 tiny residual atrial septal defects and 1 slight residual ventricular septal defect.Moderate pulmonary valve regurgitation was present in all patients,whether transannular patch was used or not.All survivors remained in good condition in NYHA class Ⅰ or Ⅱ.Conclusion Outcomes of complete correction of tetralogy of Fallot with complete atrioventricular septal defect are favorable during follow-up time.It is feasible to close a ventricular septal defect with a 2-patch technique through a transatrial approach alone.Accurate suturing is the key to the success of the surgery.
