Objective: To describe our experience in percutaneous Patent Ductus Arteriosus (PDA) closure using the Occlutech Duct Occluder (ODO).

Methods: We retrospectively reviewed patients who underwent an attempt for PDA closure with ODO between August 2013 and October 2015. Only patients with isolated PDA and weighing ≥ 6 kg were eligible for the ODO use.

Results: Eighteen ODO devices were successfully implanted in 18 patients. Age and weight ranged from 6 to 180 months (median 23.5) and 6 to 54 kg (median 11), respectively. PDA was of type A (16 patients), type E (1) and type D (1). PDA diameter ranged from 2 to 5 mm (median 3). Median procedure time was 55 minutes (range 35 to105). Median fluoroscopy time was 9.2 minutes (range 3 to 29.57). The device diameter (pulmonary end) was 5 to 8 mm (median 7). The standard shank length was used in 13 cases and the long variant in the remaining 5. Median follow-up period was 12 months. All devices were successfully implanted. Total occlusion was achieved the following day in all but 2 in whom it was confirmed 1 month later. No major complication occurred. Mild pulmonary obstruction was noted in one patient and aortic disc bulging occurred in 2 others, without hemodynamic consequences.

Conclusion: In this group of patients, the ODO has shown excellent results in terms of safety and efficiency. The long device variant may be advantageous in some large and long PDAs. Larger series are needed to compare it with the preexisting devices.
