Clinical Outcomes After Percutaneous Patent Ductus Arteriosus Closure in Adults.

BACKGROUND: There is little published data regarding percutaneous patent ductus arteriosus (PDA) closure in adults. We aim to describe the outcomes of adult patients undergoing PDA closure at a single tertiary referral centre. METHODS: All adults who underwent device PDA closure at our centre from 2001 to 2017 were identified and enrolled in the study. Available clinical data and imaging data were reviewed. RESULTS: At total of 141 patients were identified, with a mean age of 43 ± 15 years. Left ventricular dilation was present in 27% and pulmonary hypertension in 36% of the patients. Most ducts (74%) were of type A morphology. Mean ductal diameter at the pulmonary artery end was 4.1 ± 1.9 mm and mean length was 10.0 ± 4.7 mm. Wire passage from the pulmonary artery was achieved in 79%. Procedural success rate was 100%, and an Amplatzer duct occluder was deployed in all successful cases (ADO1 device in 97%). There was a small residual shunt in 6% at the time of closure, and only 2 patients had a residual leak on echocardiography at a median 3 months' follow-up. No major complications occurred. CONCLUSIONS: Transcatheter PDA closure with the use of an Amplatzer duct occluder is very effective in adults across all duct morphologies and associated with a very low complication rate.
