In this procedure, the provider performs coronary angiography, an imaging study of the vessels in the heart. He inserts tubing into an artery, typically in the groin or arm, and threads it into the left side of the heart, where he injects dye. He also injects dye into the left ventricle, the lower chamber on that side, if necessary, and into any prior bypass grafts. He supervises the collection of images and interprets the images to identify narrowing or blockages in the vessels and assess the health of the heart.
