Background: Transcatheter closure of patent ductus arteriosus (PDA) has gained acceptance over the last two decades, replacing the surgery in more than 90% of the cases, so the safety and efficacy of transcather closure of PDA have been evaluated by studying different experiences from different centers in developing countries. The aim is to report our experience with PDA transcather closure, with focus on the adverse events and complications faced during the procedure.
Results: Outcome data on PDA transcatheter closure were collected from two different tertiary centers in a multicenter registry. During the period from June 2017 till January 2021, 308 PDA closure were recorded, using device in 197 (64%) and coils in 111 (36%) patients, most of the patients were in pediatric age group from 6 months to 6 years and only 10 patients (3.2%) were adults. Most patients had isolated PDA of 92%, and 9 (2.9%) patients had residual PDAs either post-surgical or transcatheter closure. Median minimum PDA diameter was 2.8 mm (range 1-7.6 mm; IQR 1.8-3.8 mm). The procedure was successful in 293 patients (95%). Complications occurred in 15/308 patients (5%), and only 6 (2%) of them were major complications, but none was life threating. Frequent complications were device embolization (2%), hemolysis (1%), arrhythmia (1%). Younger age, low body weight and longer procedure time were associated with a high complication rate (p < 0.005). Device-related complications were more common than coil-related complications (2.5% versus 0.5%).
Conclusions: Although transcatheter closure of PDA is considered to be effective procedure with low complications rate, however, complications should be anticipated and managed properly.
