Background: Transcatheter patent ductus arteriosus (PDA) closure is an established procedure.
Objectives: The aim of the study was to assess midterm follow up of the Nit-Occlud coil and the amplatzer ductal occluder (ADO)
closure of PDA.
Patients and Methods: In this cohort study, we collected the longitudinal data of patients who underwent percutaneous closure
using coil or ADO from November 2005 to November 2013. A total of 404 patients with PDA closure by devices were included during
the study period. Coil occlusion was performed in 220 patients and 184 patients underwent catheterization using ADO. Follow-up
evaluations were performed with echocardiography at two weeks, two months, six months, and during the study period (in average
4.8 ± 3.8 years).
Results: The patients’ mean age was 24 months (range: 1 - 312). The catheterization was successful in 393 (97.2%) patients and unsuccessful
in 11 (2.7%). Immediate complete occlusion was seen in 290 (73.7 %) patients. The occlusion rates at two weeks, two months,
six months, and during the study period were 73.7%, 84%, 93.6%, 98.7%, and 99.5%, respectively. Complications occurred in 23 (5.8%)
patients during or immediately after the catheterization, and device embolization with 2.7% was the most common complication.
Most complications occurred in a patient with pulmonary hypertension who was less than one year old and was undergoing the
first year of experience with devices.
Conclusions: Our findings showed that transcatheter occlusion of the PDA is an effective and safe intervention by coil or Amplatzer
with excellent early and one-year outcomes. Pulmonary hypertension, age of less than 12 months and experience of less than one
year may increase the complications of device closure.
