Key result
Percutaneous closure of secundum atrial septal defects achieved a 93.3% procedural success rate with low short-term complication rates, including device embolisation (3.6%), residual shunt (2.2%), and arrhythmia (1.4%).
Why the study?
To evaluate the procedural and short-term results of percutaneous atrial septal defect closure in adults.

Percutaneous closure of secundum atrial septal defects in adolescents and adults is feasible and associated with a high procedural success rate (93.3%) and low short-term complications.
Short-term procedural data appear acceptable in adults; leaves open need for prospective trials before changing practice.
Objectives: To evaluate the procedural and short-term results of percutaneous atrial septal defect (ASD) closure in adults. Methodology: We retrospectively analysed 149 consecutive patients with a secundum ASD who underwent percutaneous closure from September 2011 to January 2021. Procedural and short-term results, including arrhythmia, device embolisation and residual shunt, were assessed at 2 days and 4 weeks and 6 months after percutaneous closure of atrial septal defect. Results: The patients were 14 to 77 (37.7 ± 15.0) years old and 101 (67.8%) were female. Maximum defect size was 18.0 ± 6.3 mm measured on transoesophageal echocardiography. The device diameter used in patients who underwent closure was 21.9 ± 6.9 mm (6–38 mm). Percutaneous closure procedure success rate was 93.3%. In our study, the rates of device embolisation, arrhythmia and residual shunt were 3.6%, 1.4%, and 2.2%, respectively. Conclusion: Transcatheter closure of ASDs in adults was feasible in our centre with good short-term outcome. The procedure should be performed in experienced centres by cardiologists specialised in the treatment of structural heart diseases due to potentially severe complications.

Can et al. (2022) conducted a cohort in Secundum atrial septal defect (n=149). Percutaneous atrial septal defect closure was evaluated on Procedural success rate. Percutaneous closure of secundum atrial septal defects achieved a 93.3% procedural success rate with low short-term complication rates, including device embolisation (3.6%), residual shunt (2.2%), and arrhythmia (1.4%).
