title: "Bedside" balloon septostomy in infants with transposition of the great arteries: new concepts using two-dimensional echocardiographic techniques.
abstract: We performed balloon atrial septostomies in six successive infants with transposition of the great arteries, using echocardiographic guidance at the bedside in the neonatal intensive care unit. In all cases adequate septostomy was obtained and instantaneously assessable. PaO2 values increased as expected (mean before septostomy 28 mm Hg; after, 42 mm Hg). In cases of transposition clearly diagnosed echocardiographically, this intervention need not be done in the catheterization laboratory. The need for a full hemodynamic study in the neonatal period is arguable.
