Tetralogy of fallot.

The optimal management of patients with tetralogy of Fallot has to consider the individual intra-cardiac anatomy as the most important variable, together with the age and the body weight of the patient. In any case the potential advantages of a primary early repair should be weighted against the experience and expertise of the individual centre and/or surgical team in dealing with tetralogy of Fallot and with neonates and infants. The best results are achieved by very carefully adapting the surgical technique to the individual morphology of the right ventricular outflow tract and of the pulmonary arteries. The details of the established surgical management for each component of the surgical repair are analysed and described. Over a period of 12 years (from 1993 to 2005) 318 consecutive patients with tetralogy of Fallot underwent repair with one hospital death (1/318=0.3% mortality).
