3D TEE may refine ASD sizing in complex defects versus 2D; leaves open whether it should supplant balloon measurement for device selection.
Does three-dimensional transoesophageal echocardiography improve the anatomical assessment of atrial septal defects compared to two-dimensional echocardiography and balloon sizing?
Dynamic three-dimensional transoesophageal echocardiography enhances the anatomical and physiological understanding of atrial septal defects, particularly for complex shapes and antero-superior rims, compared to 2D imaging.
