Radiation exposure in different cardiac catheterization procedures in cath lab

Area of Science:

• Cardiology
• Radiological Protection
• Medical Imaging

Background:

• Interventional cardiology procedures expose cardiologists and staff to significant radiation.
• Assessing radiation exposure is vital for occupational safety in cardiac catheterization labs.

Purpose of the Study:

• To evaluate and quantify radiation exposure levels.
• To compare radiation doses across different cardiac catheterization procedures, operators, and vascular access routes.

Main Methods:

• A descriptive cross-sectional study was conducted from November 2008 to December 2009.
• Patients were grouped by procedure: coronary angiography, percutaneous coronary intervention (PCI), permanent pacemaker (PPM), and percutaneous transvenous mitral commissurotomy (PTMC).
• Radiation doses were analyzed based on operator (consultants vs. trainees) and access site (femoral, radial, sub-clavian).

Main Results:

• Radiation doses varied considerably among procedures, with PCI showing the highest mean dose and PTMC the lowest.
• Femoral access generally resulted in higher radiation doses compared to radial or sub-clavian access.
• Consultants received higher mean radiation doses than trainees, though procedure complexity also plays a role.

Conclusions:

• Radiation exposure in cardiac catheterization is not uniform.
• Significant differences in radiation doses exist based on the specific procedure, the operator's experience level, and the chosen vascular access route.
• Findings highlight the need for tailored radiation protection strategies in interventional cardiology.
