Atrial septal defect device closure. Is balloon sizing necessary?

Abstract

Objectives: This study compared the success rate of atrial septal defect device closure in children with and without balloon sizing during the procedure. Methods: This four-year, combined retrospective and prospective study was performed at a single center. All participants underwent transcatheter closure under transthoracic echocardiography and the success rate was analyzed considering the effect of balloon sizing. Results: Eighty-eight patients with a mean age of 6.48 ± 3.32 years were enrolled. Balloon sizing was performedor in 39 (44%) patients. It didn’t change the success rate compared to 49 (56%) patients without balloon sizing. Likewise, age and sex had no effect on thesuccess rate. However; the failure rate was higher in patients with larger defects. Conclusions: The study demonstrated that balloon sizing did not influence the success rate of atrial septal defect device closure, and a precise measurement by echocardiography can be as successful as balloon sizing.
