Z95.5: Presence of coronary angioplasty implant and graft

The heart is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. Your coronary vessels were probably constricted or damaged. You thus had a treatment on your coronary vessels. Constrictions can for instance be widened. After that, tubes can also be placed in the constrictions. These tubes should keep the coronary vessel open. One of your coronary vessels may also have been replaced.
