Insights
Cardiologists face higher radiation exposure during certain electrophysiology procedures. Atrial flutter and AVNRT/AVNT ablations result in the greatest physician radiation exposure, primarily linked to X-ray time.
Area of Science:
- Cardiology
- Medical Physics
- Radiation Safety
Background:
- Cardiologists performing electrophysiology procedures are at high risk of occupational radiation exposure.
- Previous studies have not comparatively assessed radiation exposure across different electrophysiology procedures.
Purpose of the Study:
- To measure and compare radiation exposure levels for cardiologists during various electrophysiology procedures.
- To identify specific procedures associated with higher radiation doses for operators.
Main Methods:
- Analysis of 150 electrophysiology procedures over a 6-month period.
- Radiation exposure measured using personal electronic dosimeters on the operator's left arm.
Main Results:
- Radiation exposure varied significantly by procedure type.
- Compared to electrophysiology studies, exposure was 3x higher for atrial fibrillation ablation, 9x higher for AVNRT/AVNT ablation, and 10x higher for atrial flutter ablation.
- X-ray time was the primary determinant of physician radiation exposure (R²=0.28).
Conclusions:
- Significant differences in cardiologist radiation exposure exist based on the electrophysiology procedure performed.
- Atrial flutter and AVNRT/AVNT ablations pose the highest radiation risks to operators.
Purpose:
Cardiologists are among the health professionals that are most exposed to ionizing radiation, but there is no study comparing the level of exposure of physicians during different electrophysiology procedures. We aimed to measure and compare cardiologists' exposure to radiation during different electrophysiology procedures.
Methods:
The study population comprised all electrophysiology procedures performed over a 6-month period in a large referral centre. The endpoint was operator radiation exposure, assessed using a personal electronic dosimeter located on the operator's left arm.
Results:
In total, 150 electrophysiology procedures were analyzed. Compared with electrophysiology studies (reference category), physician radiation exposure was 3-fold greater during ablation of atrial fibrillation, 9-fold greater during ablation of atrioventricular nodal reentrant tachycardia (AVNRT)/atrioventricular reentrant tachycardia (AVNT), and 10-fold greater during ablation of atrial flutter (p < 0.001). Physician exposure was mainly related to X-ray time (R2 = 0.28).
Conclusions:
Our study showed significant differences in cardiologists' exposure to ionizing radiation depending on the type of electrophysiology procedure. Atrial flutter and AVNRT/AVNT ablations are the procedures in which operators are most exposed to ionizing radiation.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
