Fifty\u2010four patients were selected as comparisons. There were no significant differences in the age at catheterization, procedure time, fluoroscopy time, or contrast amount (cc\/kg). The lower\u2010birth\u2010weight infants were more likely to be premature (median age 29 vs. 37 weeks, <jats:italic>P<\/jats:italic> &lt; 0.001), and to have left\u2010sided obstructive lesions including aortic stenosis or coarctation. The comparison patients were more likely to be postoperative (28% vs. 0%, <jats:italic>P<\/jats:italic> = 0.02), and included a higher number with hypoplastic left heart syndrome. There was an increased incidence of interventions performed in the lower\u2010birth\u2010weight infants (83% vs. 41%, <jats:italic>P<\/jats:italic> = 0.002). There was a difference in the interventions performed between the two groups: the comparisons had more atrial septal procedures, and the lower\u2010birth\u2010weight infants had more coarctation dilations and aortic valve dilations. There were no significant differences in the acute success rate of the procedures (100% vs. 95%), overall complication rate (56 vs. 57%), incidence of blood transfusions (44 vs. 30%), or major complications (11 vs. 13%) between the lower\u2010birth\u2010weight and comparison groups respectively. There was a trend towards higher survival rate in the comparison group in this small study population, but it did not reach significance (80 vs. 61%, <jats:italic>P<\/jats:italic> = 0.13).<\/jats:p><\/jats:sec><jats:sec><jats:title><jats:styled-content>Conclusions:<\/jats:styled-content><\/jats:title><jats:p>Cardiac catheterization in neonates &lt;1,500 g is more likely to include percutaneous intervention, especially on the left side, but is generally successful with a complication rate similar to procedures performed in larger infants.
