Abstract

OBJECTIVES: To determine the success rate of transcatheter closure of secundum atrial septal defects (ASDs) in adults and to characterize anatomical structures predisposing to unsatisfactory results. PATIENTS AND METHODS: Preinterventional and follow-up transesophageal echocardiography of 17 consecutive patients treated with a Sideris buttoned device was reviewed. Residual jet size of 5 mm or smaller was considered an adequate result; jet size larger than 5 mm was inadequate. Maximal ASD diameter, ASD area, and anterior, posterior, superior, and inferior septal rims were measured. RESULTS: The 7 patients with adequate results (41%) had smaller defects before implantation of a buttoned device (mean SD maximal ASD diameter, 12 4 vs 19 5 mm; P
