Percutaneous transcatheter device closure of secundum atrial septal defects (ASD) has now largely replaced surgical closure in most centres. The aim of this study was to compare results of transcatheter and surgical ASD closure in adults in Latvia during the years 2002-2014 and to analyse long-term outcomes of transcatheter closure. We analysed data from 334 patients with secundum ASD who underwent ASD closure in Pauls Stradiņč Clinical University Hospital. Patients were included into device or surgical closure groups. In the device group, three follow-ups were made 1, 6, and 12 months after the procedure. No follow-up data were available for surgical arm patients beyond their hospitalisation period. The mean age of patients was 45.3 ± 19.9 years for the device group and 40.0 ± 16.9 years for the surgical group (p = 0.023). The mean secundum ASD size in the device and surgical groups was 14.2 ± 5.6 mm and 28.7 ± 10.0 mm, respectively (p < 0.001). No differences were observed regarding procedure success rates: 99.2% in the device group and 100% in the surgical group (p = 0.451). Periprocedural complications generally were more common in the surgical closure group. The study results show a successful introduction of the percutaneous ASD closure method in Latvia with good early and late outcomes and without significant differences in procedure success rate compared to surgical closure.
