Optimal degree of pulmonary artery banding--adequate circumference ratio to calculated size from normal pulmonary valve dimensions.
These findings suggest that PA banding may be suitable in children with congenital heart disease and excessive pulmonary flow, and that best results are obtained when the band circumference is < 90% of the standard pulmonary valve-ring circumference, as calculated from an equation derived from normal pulmonary valve dimensions. This guideline applies equally well to small infants weighing < 3 kg and to larger patients.
