Effect of Atrial Septal Defect Shape Evaluated Using Three-Dimensional Transesophageal Echocardiography on Size Measurements for Percutaneous Closure

The relationships between the SBDs and maximal diameters measured on two-dimensional and 3D-TEE images are influenced by the ASD shape and size. Therefore, the ASD shape, as well as the size, should be considered when the device size is determined without SBD measurement.
