Objective: Tetralogy of fallot (TOF) is one of the most common forms of
cyanotic congenital heart disease (CHD). The aim of this study was
determination of demography, associated anomalies, peripheral pulmonary
stenosis (PPS), blood grouping, Rh typing, operation results and
complications in TOF. Material & Methods: The records of 270
patients were reviewed. These patients were admitted from 1993 to 2003,
in Shaheed Rajaei Hospital. Findings: Male patients were 60.37% and
females were 39.63%. Incidence of patent foramen ovale (PFO), Right
Aortic Arch (RAA), coronary artery (CA) anomalies and other anomalies
were 44.81%, 21.11%, 9.25% and 36.30% respectively. Single ostium
coronary artery (SOCA) was the most common CA anomaly. The most common
PPS was bifurcation stenosis. TOF was more common in O blood group
patients. The mean age at the first palliative operation was 5.21 years
and for TC was 7.19 years. Post surgical mortality rate was about 3%
and morbidity rate, 12.18%. Conclusion: Trend toward earlier total
correction (TC), and single stage early TC of TOF should be recommended
as the preferred management strategy
