Abstract/Summary

Aims To examine determinants of access to treatment, outcomes, and hospital utilization in patients undergoing secundum atrial septal defect (ASD) closure in adulthood in England and Wales. Methods and results Large retrospective cohort study of all adult patients undergoing secundum ASD closures in England and Wales between 2000/01 and 2016/17. Data were from population-based official data sets covering congenital heart disease procedures, hospital episodes, and death registries. Out of 6541 index closures, 79.4% were transcatheter [median age 47 years, interquartile range (IQR) 34–61] and 20.6% were surgical (40 years, 28–52). The study cohort was predominantly female (66%), with socioethnic profile similar to the general population. Mortality in hospital was 0.2% and at 1 year 1.0% [95% confidence interval (CI) 0.8–1.2%]. Risk of death was lower for transcatheter repairs, adjusting for age, sex, year of procedure, comorbidities, and cardiac risk factors [in-hospital adjusted odds ratio 0.09, 95% CI 0.02–0.46; 1-year adjusted hazard ratio 0.5, 95% CI 0.3–0.9]. There was excess mortality 1 year after ASD closure compared with matched population data. Median (IQR) peri-procedural length of stay was 1.8 (1.4–2.5) and 7.3 (6.2–9.2) days for transcatheter and surgical closures, respectively. Hospital resource use for cardiac reasons started the year before repair (median two inpatient and two outpatient-only days) and decreased post-repair (zero inpatient and one outpatient days during the first 2 years). Conclusion This national study confirms that ASD closure in adults, by surgical or transcatheter methods, is provided independently of ethnic or socioeconomic differences, it is low (but not no) risk, and appears to reduce future cardiac hospitalization even in older ages.
