Patient radiation doses in interventional cardiology procedures

Area of Science:

• Medical Physics
• Radiology
• Cardiology

Background:

• Interventional cardiology procedures frequently involve prolonged fluoroscopy and radiographic exposure, leading to substantial patient radiation doses.
• Common procedures include coronary angiography, percutaneous coronary interventions, electrophysiology studies, and radiofrequency catheter ablation.

Purpose of the Study:

• To review and synthesize patient radiation doses from interventional cardiology procedures based on international scientific literature.
• To identify factors contributing to the wide variability in radiation doses observed across studies.

Main Methods:

• A comprehensive literature review of 72 relevant studies published over the last 22 years.
• Analysis of reported patient radiation doses for non-pediatric interventional cardiology procedures.

Main Results:

• Patient radiation doses vary significantly among different interventional cardiology procedures and even within similar studies.
• Observed discrepancies in radiation doses are attributed to patient-specific factors, procedural characteristics, physician expertise, and fluoroscopic equipment variations.

Conclusions:

• Interventional cardiology procedures expose patients to considerable radiation doses.
• Continuous efforts are necessary to minimize patient radiation exposure during these cardiac interventions.
