Objective:

To evaluate the impact of suspended lead suits on occupational radiation exposure among interventional echocardiographers during left atrial appendage occlusion (LAAO) procedures.

Approach:

Key Findings:

• Median head-level radiation dose was 0 μSv with suspended lead suits vs 11 μSv with traditional lead aprons.
• 60% of procedures with suspended lead suits had undetectable radiation exposure, compared to none with traditional lead aprons.
• 30% of procedures with traditional lead aprons had exposure of at least 20 μSv, while none with suspended lead suits did.
• Even after adjusting for procedural radiation use, exposure remained lower with suspended lead suits (0.0 μSv/Gy × cm² vs 0.6 μSv/Gy × cm²).

Interpretation:

The use of suspended lead suits significantly reduces occupational radiation exposure for interventional echocardiographers during LAAO procedures, which is critical given the associated long-term health risks.

Limitations:

• The study was conducted at a single institution, limiting generalizability.
• Focus was solely on LAAO procedures, which may not reflect outcomes in other structural heart interventions.
• Further multicenter studies are needed to assess variability and cost-effectiveness.

Conclusion:

Suspended lead suits may offer a safer alternative to traditional lead aprons in reducing radiation exposure during LAAO procedures, warranting further investigation.
