Assessment of left atrial remodeling using speckle tracking echocardiography after percutaneous atrial septal defect closure in adult patients

Abstract Background Atrial fibrillation (AF) is a well-known, long-term complication of atrial septal defect (ASD) in adults, even after device closure. Left (LA) strain rate applied to the analysis chamber function has been demonstrated be an important predictor LA reverse remodeling. This study aimed determine changes closure ASD. Methods prospective enrolled adults with secundum ASD undergoing transcatheter from December 2016 August 2017. We analyzed clinical characteristics and before six months Results A total 11 patients were enrolled. The mean age was 42.6 ± 9.9 years, (54.5%) females. There no significant change conventional echocardiographic parameters global reservoir 1.17 0.34 0.85 0.30 ( p = 0.030). median conduit 0.68 (0.42–1.16) 0.41 (0.16–0.79) 0.213), respectively. contractile at six-month follow-up showed improvement compared pre-procedural (0.33 0.65 vs. − 0.43 0.38, 0.006). Conclusions functional occurred during follow-up, while right (RA) geometric not significant. remodeling proved by restoration late diastolic function.
