Final answer:
A graft can be anastomosed between the coronary arteries to revascularize the heart muscle in a patient with heart disease.
Step-by-step explanation:
An anastomosis is a connection between two blood vessels. In the case of revascularizing the heart muscle, a graft can be anastomosed between the coronary arteries. These arteries branch from the aorta and supply blood to the heart. By creating a graft between the coronary arteries, blood flow can be restored to the heart muscle, helping to treat heart disease.
