Radiation Safety in Chronic Total Occlusion Percutaneous Coronary Intervention.

Chronic total occlusion percutaneous coronary intervention (CTO-PCI) is a complex, high-radiation procedure that requires careful radiation management to protect both patients and health care providers. This review outlines the biological risks of radiation exposure, differentiating deterministic and stochastic effects, and highlights key safety thresholds and regulatory guidelines. It presents a range of mitigation strategies across procedural phases, including advanced shielding systems, low-dose imaging platforms, and real-time monitoring tools. Institutional protocols and a culture of shared accountability are emphasized to support the ALARA principle. Emerging technologies offer promising solutions to reduce operator exposure and improve safety outcomes in modern CTO-PCI practice.
