BACKGROUND Stenting for aortic coarctation (CoA) has been accepted as an alternative to surgery for adolescents and adults, but only a few case have been reported in Japan. The purpose of this study was to provide a detailed review of Japanese national data on stenting of CoA. METHODS In a subanalysis of the data of the Japanese Society of Pediatric Interventional Cardiology (JPIC), we identified 35 patients with CoA who underwent stenting. We analyzed procedural characteristics including factors that may have contributed to hemodynamic effectiveness, and we compared these parameters between the patients under and over 15 years of age. RESULTS The mean ratio of balloon diameter/minimum lumen diameter (MLD) before stenting was 1.7 (range, 1.2-4.0), and the mean difference between the balloon diameter and the reference vessel diameter was -0.7 mm (range, -5.0 to +3.0 mm). %MLD/balloon diameter, which was defined as [(balloon diameter - MLD after dilation)/balloon diameter] × 100 predicted achievement of
