coronary angiogram
Diagnostic imaging procedure using contrast injection to visualize coronary artery anatomy and pathology.
Full Definition
A minimally invasive diagnostic procedure where contrast material is injected into the coronary arteries through a cardiac catheter, allowing real-time X-ray visualization of vessel anatomy, stenosis location and severity, and collateral circulation. The procedure provides the gold standard assessment of coronary artery disease and guides treatment decisions. Results are typically reported with specific vessel nomenclature and stenosis percentages.
Usage
Usage note: Distinguish from therapeutic angioplasty procedures in documentation.
