Key result
Very low frame rate fluoroscopy is linked to ~75% lower radiation exposure during PCI.
Why the study?
The feasibility and efficacy of very low frame rate fluoroscopy protocol during PCI to reduce radiation exposure without compromising outcomes was not established.
Does a very low frame rate fluoroscopy protocol reduce radiation exposure in patients undergoing percutaneous coronary intervention?
Comparison
Very low frame rate fluoroscopy protocol (3.8 and 7.5 fps) vs standard 15 fps fluoroscopy protocol
Design
Retrospective cohort study

Does a very low frame rate fluoroscopy protocol reduce radiation exposure in patients undergoing percutaneous coronary intervention?
Effect estimate: 74.7% reduction
Absolute Event Rate: 433% vs 1714%
p-value: p=<0.0001
Implementing a very low frame rate fluoroscopy protocol during PCI significantly reduces patient radiation exposure without compromising procedural efficiency or clinical safety.
Gupta et al. (2021) conducted a cohort in Obstructive coronary artery disease requiring Percutaneous Coronary Intervention (PCI) (n=326). Very low frame rate fluoroscopy (VLFF) protocol (3.8 + 7.5 fps) vs. Standard fluoroscopy protocol (15 fps) was evaluated on Radiation exposure measured by Air Kerma (mGy) (74.7% reduction, p=<0.0001). The very low frame rate fluoroscopy protocol (3.8 and 7.5 fps) reduced radiation exposure by 74.7% compared to the standard 15 fps protocol during percutaneous coronary intervention.
