Peripheral and coronary arteriography, as well as left ventriculography, are imaging procedures used to diagnose and evaluate cardiovascular conditions. These procedures involve the injection of contrast dye into the arteries of the heart or other blood vessels, which helps create detailed images of the blood flow and the structure of the heart and blood vessels.
During the procedure, a thin, flexible catheter is inserted into a blood vessel in the arm or leg and guided to the site of interest. The contrast dye is then injected into the catheter and images are taken using X-ray imaging technology. In coronary arteriography, the dye is injected into the coronary arteries, which supply blood to the heart muscle, while in peripheral arteriography, the dye is injected into other blood vessels outside of the heart, such as in the arms, legs, or kidneys.
Left ventriculography involves the injection of contrast dye into the left ventricle of the heart, which is the chamber responsible for pumping oxygen-rich blood out to the body. This allows doctors to evaluate the size, shape, and function of the left ventricle.
These imaging procedures can help diagnose and evaluate a variety of cardiovascular conditions, such as coronary artery disease, peripheral artery disease, heart valve disorders, and heart failure. The results of these tests can help guide treatment decisions, including the use of medications, surgery, or other interventions.
