Objective: The intermediate results achieved with a new technique for primary repair of tetralogy of Fallot with absent pulmonary valve syndrome are reported. Method: Apart from correction of tetralogy of Fallot, this approach includes translocation of the pulmonary artery anterior to the aorta and away from the tracheobronchial tree. Since November 1998 this technique has been employed in three symptomatic newborns and three infants with a diagnosis of tetralogy of Fallot with absent pulmonary valve. The median age at surgery was 37 days (range 14–256 days). The median weight at operation was 3.4 kg (range 2.9–4 kg). All patients had severe respiratory problems and congestive heart failure with cyanosis. Results: There was no early or late death during the follow-up (median 27 months). One patient required redo due to failure to thrive as a consequence of right ventricle volume overload. Valved conduit was inserted to pulmonary position. Respiratory symptoms disappeared or were significantly reduced in all patients. Postoperative computed tomographic scan showed no compression of trachea and main bronchi, pulmonary artery was away from tracheobronchial tree in all patients. Patients are doing well with adequate growth. Conclusions: The new technique described here has a potential to reduce or eliminate bronchial compression by pulmonary artery. Translocation of pulmonary artery anterior to the aorta takes the dilated pulmonary artery away from the trachea and bronchial tree. This approach was found to be technically feasible and can be useful especially in symptomatic newborns and infants.
