Cardiac catheterization often necessitates the use of fluoroscopy to visualize the path of the catheter as it enters the heart or as it enters the coronary arteries. The coronary arteries are recognized as "epicardial vessels" as theyarein theepicardium, thefarthest layer of theheart. The useof fluoroscopy requires radiopaquecontrast, which inrarecases can lead to contrast-induced kidney injury(see Contrast-inducednephropathy). People are constantly uncovered to down doses of ionizing radiation through procedures. Ideal table positioning amongst the x-ray source and receiver, and radiation monitoring via thermoluminescent dosimetry, are two keywaysof easing a person's exposure to radiation. People with certain comorbidities (people who have more than one condition at the same time) have a higher peril of adverse events during the cardiac catheterization procedure. These comorbidity conditions comprise aortic aneurysm, aortic stenosis, extensive three-vessel coronary artery disease, diabetes, uncontrolled hypertension, obesity, chronic kidney disease, and unstable angina.
