To describe early clinical experience with the amplatzer ductal occluder II additional sizes (ADO II AS) for percutaneous arterial duct occlusion in infants and small children.

Pre‐, intra‐ and postprocedural data analysis of all patients undergoing arterial duct occlusion with the ADO II AS from three tertiary referral centers.

17 patients (10 female) with a median age of 6 months (range 1.0–48.1 months) and a median weight of 5.7 kg (range 1.7–17.4 kg) underwent attempted transcatheter ductal closure with the ADO II AS. Retrograde arterial approach was used in eight patients with transvenous femoral approach used in nine. The mean minimal ductal diameter was 2.2 ± 0.7 mm with mean ductal length of 6.8 ± 1.7 mm. Device sizes used were 5/6 (n = 5), 3/4 (n = 4), 4/4 (n = 3), 4/6 (n = 3), and 5/4 (n = 2) with four French delivery sheaths used in all cases. The median fluoroscopy time was …
