Abstract
long device variant may be advantageous in some large and long PDAs. Larger case series are needed to compare the ODO with preexisting devices.

Introduction
Since the rst successful transcatheter closure of patent ductus arteriosus (PDA) by Porstmann in 1967 [1, 2], several di erent PDA closure devices have been developed and evaluated. Today, percutaneous clo- sure of almost any PDA beyond neonatal age can be easily and safely performed using detachable coils or speci cally designed occluders, including di erent generations of the Amplatzer Duct Occluder (ADO I, II, and AS) [3-5]. Nevertheless, some large and long (i.e., “slow tapering”) type A PDAs and nonconical large PDAs still pose technical di culties to the inter- ventionist, especially in small infants.
A new device, the Occlutech Duct Occluder (ODO), has been designed with the aim of addressing some of these challenges. Like the ADO I, the ODO is con- structed from braided Nitinol wires, has an aortic

Objective: To describe our experience in percutaneous patent ductus arteriosus (PDA) closure using the Occlu- tech Duct Occluder (ODO).
Methods: We retrospectively reviewed records of pa- tients who underwent a PDA closure attempt using the ODO between August 2013 and October 2015. Only pa- tients with isolated PDA and weighing ≥6 kg were eligi- ble for ODO use.
Results: Eighteen ODO devices were successfully im- planted in 18 patients. Patient age and weight ranged from 6 to 180 months (median, 23.5 months) and 6 to 54 kg (median, 11 kg), respectively. PDAs were of type A (n = 16), type E (n = 1), or type D (n = 1). PDA diameter ranged from 2 to 5 mm (median, 3 mm). Median proce- dure time was 55 min (range, 35–105 min). Median u- oroscopy time was 9.2 min (range, 3.0–29.6 min). The device diameter (pulmonary end) was 5–8 mm (medi- an, 7 mm). The standard shank length was used in 13 cases, and the long variant was used in ve cases. Me- dian follow-up period was 12 months. All devices were successfully implanted. Total occlusion was achieved the following day in all but two patients, in whom it was con rmed one month later. No major complica- tions occurred. Mild pulmonary obstruction was noted in one patient, and aortic disc bulging occurred in two patients without hemodynamic consequences. Conclusion: In this group of patients, the ODO showed excellent results in terms of safety and e cacy. The
