In plain language
In 22 children having atrial septal defect closure, using 3D transesophageal echo to guide right heart catheterization cut fluoroscopy time by 54% and patient radiation by 78% versus historical controls. Staff dose was not measured, though less fluoroscopy likely lowers it.

What it found
3D transesophageal echocardiography (TEE) guidance of right heart catheterization in atrial septal defect (ASD) closure reduced total fluoroscopy time and radiation dose compared with historical controls.
Key figures: 54% reduction in fluoroscopy time; 78% radiation reduction
Fluoroscopy time for the right heart catheterization step under 3D TEE guidance was almost zero.
Key figures: mean 0.06 ± 0.23 min
RHC time decreased along the learning curve.
Key figures: r = -0.63, P < .01
No significant differences in RHC time or total procedural time versus controls.
Limits to keep in mind
Small single-series study with historical controls, so groups may differ in ways other than guidance method. Only patient dose and fluoroscopy time were measured; staff dose was not assessed.
