Cardiac catherization or heart cath is the approach where the insertion of the catheter into a chamber or vessel of the heart. It can be utilized as part of a therapeutic regimen to make better consequences for survivors of out-of-hospital cardiac arrest. Cardiac catheterization habitually obliges the use of fluoroscopy to visualize the path of the catheter as it penetrates the heart or as it enters the coronary arteries. Catherization technique may be a few types which could comprise: Left heart catherization, Right heart catherization, Coronary catherization.
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 they are in the epicardium, the farthest layer of the heart. The use of fluoroscopy requires radiopaque contrast, which in rare cases can lead to contrast-induced kidney injury (see Contrast-induced nephropathy). 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 keyways of 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.
