ABSTRACT

Objective To discuss the surgical technique in correction of tetralogy of Fallot with complete atrioventricular septal defect (TOF-AVSD). Methods 16 patients aged 2-16 years underwent correction of TOF-AVSD. The atrioventricular septal defect was closed through a right atriotomy and longitudinal right ventriculotomy in each case. The three-patch technique was used for the first 7 cases and two-patch technique for the later 9 cases. The commissure between the superior and inferior bridging leaflets of the left portion of the common atrioventricular valve was closed in each patient. RVOT obstruction was relieved by a transannular patch. Results Results There were 4 deaths in the early postoperative period, 3 deaths in the first 7 cases compared to 1 death in the later 9 cases (P
