Abstract

Anatomical atrial septal defect (ASD) diameter measured by transesophageal echocardiography (TEE) underestimates the Amplatzer septal occluder (ASO) size for ASD closure. The aim of this study is to investigate whether a new echocardiographic diameter (procedural ASD diameter) may enable precise measurements of ASO device size. Fifty adult patients with secundum ASD were evaluated by TEE for percutaneous closure. The procedural ASD diameter was measured using the steadier rim borders where thickness was 2.5 mm. Out of the 50 patients, 12 were considered unsuitable for Amplatzer device closure. The other 38 patients underwent percutaneous closure. The mean anatomical ASD diameter was 14.8 ± 7.0 mm, the mean procedural ASD diameter measured 19.5 ± 8.1 mm, and the mean stretched balloon diameter (SBD) was 20.0 ± 8.0 mm. ASO device size was 20.1 ± 8.0 mm. At linear regression analysis, a high correlation (r = 0.99) was found between procedural ASD diameter and SBD. Procedural ASD diameter correlates with SBD and may allow reliable prediction of Amplatzer device in an adult population undergoing percutaneous ASD closure.
