Balloon dilation of pulmonary venous pathway obstruction after Mustard repair for transposition of the great arteries.
Percutaneous balloon dilation was attempted in three patients with mid baffle pulmonary venous pathway obstruction after the Mustard operation for transposition of the great arteries. The procedure was unsuccessful in a 3 year old boy. Evidence for relief of obstruction in the other two patients (7 and 14 years old, respectively) consisted of angiographic demonstration of improved caliber at the site of the pulmonary venous pathway narrowing, improvement in the Doppler spectral signal at this site from an "obstructed" to a "normal" pattern as well as symptomatic improvement. Balloon dilation was performed twice in one of these patients. The Doppler and symptomatic improvement were sustained in both patients at short-term follow-up (5 and 6 months, respectively). This technique may offer effective relief of pulmonary venous pathway obstruction in some patients with this complication of the Mustard operation.
