Percutaneous balloon angioplasty in an infant with obstructed total anomalous pulmonary vein return.

ABSTRACT

This is a report of successful dilation of stenosis of the common trunk in a case of total anomalous pulmonary vein return into the left superior vena cava in a 3 month old infant. Percutaneous angioplasty was performed with a 6 mm diameter balloon catheter. Right ventricular systolic pressure decreased from 96 to 60 mm Hg, mean pulmonary vein pressure decreased from 26 to 14 mm Hg and left ventricular systolic pressure increased from 70 to 90 mm Hg.
