Coronary angiography

Picture
Developed by Mason Sones in the 1950's coronary angiography is regarded as the gold standard test for the diagnosis of coronary artery disease.


Most cases are performed by a radial artery (wrist) approach. After infiltration of a small amount of local anaesthetic into the wrist a small tube (sheath) is passed into the radial artery. Through the sheath a catheter is passed up the arteries of the arm to the heart and then a small amount of contrast is injected into the coronary arteries which supply the heart muscle. During the injection an X ray picture is taken which allows the cardiologist to see if there are any significant narrowings of the arteries.


Interesting Angiography Appearances

The Accordion Effect: A complex stenosis was observed between the 2 stents in the LIMA. Administration of intracoronary glyceryl trinitrate had no effect. This lesion appeared when the LIMA was straightened by the guidewire so it was assumed to be a pseudo lesion. The pseudo lesion disappeared after the guidewire in the guiding catheter was pulled back as shown in the video.  (Muller et al., Circulation 1998)
