Efficacy of Three Dimensional Transesophageal Echocardiography for Percutaneous Device Closure in Atrial Septal Defect
Background: Three-dimensional echocardiographic image for atrial septal defect (ASD) is useful for evaluation of defect size and shape. The investigators suggested optimal device size using three-dimensional transesophageal echocardiographic image and our formula in previous study. Purpose: In this study, the investigators seek to predict the correct device size and confirm the accuracy of the formula that we made before device closure in ASD patients.Start: March 2014
