Show Summary Details


The technique of coronary angiography provides and records an instantaneous real-time fluoroscopic assessment of coronary luminal anatomy. It is used both as a diagnostic tool for the assessment of coronary disease and to provide the images which guide percutaneous coronary intervention (PCI). The procedure involves the injection of a bolus of radio-opaque contrast agent through a catheter placed in the coronary ostium, thereby delineating the luminal structure of the epicardial coronary arteries when viewed using simultaneous fluoroscopy. Angiography allows the identification of areas of intimal atheroma which impinge on the vessel lumen with potential to impair blood flow. In conjunction with clinical assessment and non-invasive investigation, the number, extent, location, and distribution of these coronary stenoses are pivotal in determining the optimal revascularization strategy, whether by surgical or percutaneous techniques.
