Hiremath G, Meadows J, Moore P. How Slow Can We Go? 4 Frames Per Second (fps) Versus 7.5 fps Fluoroscopy for Atrial Septal Defects (ASDs) Device Closure. Pediatr Cardiol. 2015 Jun;36(5):1057-61.

Radiation exposure remains a significant concern for ASD device closure. In an effort to reduce radiation exposure, the default fluoroscopy frame rate in our Siemens biplane pediatric catheterization laboratory was reduced to 4 fps in November 2013 from an earlier 7.5 fps fluoro rate. This study aims to evaluate the components contributing to total radiation exposure and compare the procedural success and radiation exposure during ASD device closure using 4 versus 7.5 fps fluoroscopy rates.
