Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Therapeutic introduction of various substances into the circulation to occlude vessels, either to arrest or prevent hemorrhaging, to devitalize a structure, tumor, or organ by occluding its blood supply, or to reduce blood flow to an arteriovenous malformation. Angiography is the X-ray imaging of blood vessels using contrast agents injected into the bloodstream (see Angiography). x Ischemic heart disease and the resulting heart failure continue to carry high morbidity and mortality, and a breakthrough in our understanding of this disorder is needed.
