coronary angiography
Imaging procedure using contrast dye to visualize the coronary arteries and assess for blockages or narrowing.
Full Definition
An invasive imaging technique that involves cardiac catheterization with injection of radiographic contrast material into the coronary arteries to visualize luminal anatomy and detect stenotic lesions. The procedure provides detailed assessment of coronary artery disease severity, location, and morphology, guiding decisions for revascularization therapy. Digital subtraction angiography allows for high-resolution imaging with reduced contrast load. Complications are rare but may include bleeding, contrast nephropathy, or vascular injury.
Usage
Usage note: Distinguish from non-invasive CT coronary angiography when referring to catheter-based procedure.
