Popis: 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
