Key result
Percutaneous balloon catheter dilatation successfully relieved recurrent pulmonary venous atrial stenosis in an infant, with clinical and echocardiographic improvement persisting at 9 months.
Why the study?
Does percutaneous balloon catheter dilatation improve haemodynamics and echocardiographic parameters in an infant with recurrent pulmonary venous atrial stenosis after a Senning procedure?

Does percutaneous balloon catheter dilatation improve haemodynamics and echocardiographic parameters in an infant with recurrent pulmonary venous atrial stenosis after a Senning procedure?
Percutaneous balloon catheter dilatation can successfully relieve recurrent pulmonary venous atrial stenosis after a Senning procedure in infants, though infection risks exist.
May support balloon dilatation for post-Senning pulmonary venous stenosis in infants; hypothesis-generating and requires prospective confirmation before practice change.
Pulmonary venous atrial stenosis developed after a modified Senning procedure in an infant with transposition of the great arteries. The pulmonary venous atrium was surgically revised, but the obstruction recurred. The stenosis was then enlarged by percutaneous balloon catheter dilatation. There was an immediate haemodynamic and echocardiographic improvement. Clinical and echocardiographic improvement persisted nine months after dilatation. The procedure was complicated by staphylococcal endarteritis.

Coulson et al. (1990) conducted a case report in Pulmonary venous atrial stenosis (n=1). Percutaneous balloon catheter dilatation was evaluated on Haemodynamic and echocardiographic improvement. Percutaneous balloon catheter dilatation successfully relieved recurrent pulmonary venous atrial stenosis in an infant, with clinical and echocardiographic improvement persisting at 9 months.
