Introduction
This study was conducted with the permission of the local ethics
committee. Complete atrioventricular septal defect was defined by
Lillhei et al. in 1955. 1-2 It constitutes 3 to 4% of
all congenital cardiac defects, and insidance of 2-3 per thousand live
births.3 It is observed most often with Down syndrome
(25-71%) and is more common in females. S/M = 1.3/1. Surgical morbidity
and mortality, which were high in the early periods, have come to the
present day by being improved with a better understanding of congenital
surgical anatomy, success in the treatment of pulmonary hypertension,
surgical techniques, and the guidance of technological
developments.6,7,8 Almost all cases can be operated
with good outcomes in the early stages of the
disease.9
Complete correction surgery, which started with the use of the TPT by
Trusler in 1975, has now evolved into a surgery that tends to not use
patches for VSD closure with the MSP technique of Ben Wilcox and Graham
Nunn. 3,8,10,11 Along with all these, ideal surgical
timing, optimal treatment strategy (primary or staged surgery), single
– two-patch techniques are still controversial.
