OBJECTIVES: To investigate the efficacy and safety of percutaneous transluminal balloon dilation (PTBD) for the treatment of bilateral pulmonary artery banding (bil-PAB) site stenosis. BACKGROUND: Although bil-PAB is an alternative initial treatment for high-risk neonates with hypoplastic left heart syndrome (HLHS) or critical aortic stenosis (cAS), those patients often suffer from desaturation because of progressive stenosis of the bil-PAB sites during the interstage period. METHODS: We retrospectively evaluated the efficacy and safety of 11 consecutive PTBD procedures performed between 2006 and 2012 to treat bil-PAB site stenosis in four high-risk infants (three females) with HLHS or cAS. RESULTS: PTBD was repeated twice in two patients and three times in one patient over intervals. The mean balloon diameter (BD) and BD-to-band circumference (BC) ratio were 3.1 ± 0.5 mm and 0.31 ± 0.06, respectively. After the procedures, the mean minimum lumen diameter was dilated significantly from 1.1 ± 0.1 mm to 1.7 ± 0.3 mm (P < 0.01), and the mean peripheral oxygen saturation increased significantly from 75 ± 8% to 85 ± 4% (P < 0.01). All patients reached the next stage operation involving the Norwood & bidirectional Glenn or Ross procedure, after growth. No complications such as band rupture occurred. CONCLUSIONS: For progressive stenosis of bil-PAB sites, PTBD using a balloon size that did not exceed the BC (BD around 30% of the BC) was an effective and safe procedure.
