Key result
Real-time 3D TEE was feasible for guiding transcatheter ASD closure in all patients, though short-axis dimensions differed from 2D TEE by a mean of -1.4 mm (P<0.05).
Why the study?
Does RT3D TEE provide feasible guidance and comparable dimension measurements to ICE and 2D TEE in patients undergoing transcatheter ASD closure?

RT3D TEE may be feasible for ASD closure guidance in select cases; leaves open comparability to 2D TEE given dimensional differences in this case report.

RT3D TEE is a feasible alternative to ICE and 2D TEE for guiding transcatheter ASD closure, offering en-face visualization and potentially lower costs.
Lodato et al. (2009) conducted an observational in Ostium secundum atrial septal defect (n=13). Real-time three-dimensional transoesophageal echocardiography (RT3D TEE) vs. Intracardiac echocardiography (ICE) and two-dimensional TEE was evaluated on Feasibility of RT3D TEE to guide ASD closure and comparison of ASD and balloon dimensions (MD -1.4 mm, p=< 0.05). Real-time 3D TEE was feasible for guiding transcatheter ASD closure in all patients, though short-axis dimensions differed from 2D TEE by a mean of -1.4 mm (P<0.05).
